Yes, it was nice to get compression back up, thanks to Mike Marra for coming through with a camshaft during his lunch break.

No problem Mike. Glad to help out in some way. Can't wait to see the car run on Saturday.

Car held up and ran great all day. About 8 runs total, launchin at 6k rpm. Started at 10 lbs of boost and finished up at 14 like planned. With Brian driving it ran back to back 12.99 with identical 1.78 60 ft time @ 104 mph. I had a best of 13.3x with a 60 ft of 1.87 @ 102 mph. We're on the safe side of the tune at 14 psi which I'm perfectlly ok with. Didn't have time to try to adjust cam, play with fuel or timing. I'll take a little break to learn more about tuning the Electromotive and hopeuflly have it tuned to 20 psi by spring time.

Ok, just look at the data log.

Max boost was 196.93 kpa which my math works out to be about 13.866 psi.
A/F ratios were conservativde accrossed the board, rarely getting into the 12's.
Injector Duty Cycle peaked at 75%.
I'll post the timeslip and BIN file later.

Somewhere on here there is a thread about lowest boost vs. 1/4 time. You should dig that up and post in it. You'll be in the top 5 for sure.

Thanks. Had a MAJOR discovery this morning. Brian noticed the crank compression was 110, 110, 110 and 78. Gulp, could spell major disaster. Then did a leakdown test.....8%, 7%, 8% and 5%. Hmmmm, now what does this mean.....turns out the cam was a bad grind. Replaced it with a stock turbo roller cam and wahla......150 compression across the board. Wow, that was a close call there. Nice find Brian!

I think with my current Fuel Curve (Time for One Gama (TOG) setup, my injectors will be at 85% percent around 17.2 psi.

So my goal will be to flatten my fuel curve so I can reach 85% duty cycle around 22 psi.

If I keep max rpm's at 6300 this will keep my pulse width around 16 which I think is about max for 52# injectors.

All of this is new to me so first I'll bump the boost up to 17 to see if indeed my injectors are maxed. Then I'll try playing around with the fuel curve to see if I can turn up the boost even more while keeping a close eye on AFR's.

When you run the numbers the injector DC gets pretty crazy at around 22PSI on paper. Many people have pushed them much, much farther than that of course. I prefer to play it safer rather than being sorry.

I input these numbers at the bottom under the fuel injector worksheet. 360, 4, 0.65, .85, 43.5 and come up with 72 lb injectors. I've tried other charts that include charting max rpm and come up with just about the same thing. The key number in the equation is BFSC and I hear with turbo cars the number is between .60 and .65. If you change that value to .50 then the 52 lb injectors seem to be ok but that's for NA cars.

Here is the other chart I used.

FWIW I usually use .48 for my BSFC numbers when working with higher HP 8v motors in our community. I've attempted to isolate "the right" bsfc number for certain cars of which I know their approx. HP from weight an MPH. If I use that number I have found that most calculations I use work out quite well. Frank's turbo calculator produces great results there too.

That is good to know, thanks Brian. We'll play with the VE table with the +40's past 17 psi before we just swap out to the new injectors.

I know it depends on your specific setup, but what are some of you other guys using for BSFC?

Street tuning went well today. Got the lean spot out at 5k so now my afr ratios are pretty steady around 11.6 ish. I do have fat spot around 4k that I'll get to later. Turned up the boost today to just over 15. Once I get more comfortable with making changes to the software, I'll turn on the EBC Brian hooked up and I'll give that a go with 1 psi increments till I'm happy.

Changed the front pads to the Hawk pads as the Porterfield R4's were way too dusty. My old set of R4's weren't like that so I just kept them on for street driving as well.

What's a good setting for afpr? I know it all depends on your setup but just thought I'd ask. I turned it up to 48psi or so and it seemed to help.

Generally I would start at stock 55psi fuel pressure and work from there. Since you are able to tune your fuel with the engine management, and you are running relatively low boost, I would keep the base fuel pressure higher for better spray.

I'm just the opposite.... I like to try to get pressure in the 40 to 45 psi range to keep the pump in the happy range when you are running 25psi+ boost pressure and a 1:1 AFPR.

Running 15 psi right now....but will soon be up to 22 when I feel comfortable turning on the ebc.

It sounds like I'm right in between what you and Mike are saying. I'm at 50 right now. I only plan to take it up to 22 psi or so. Probably anymore than that and the Super60 turbo is out of it's range of effectiveness.

ETA: I thought about it for a second and they probably just want the flow rate of the injectors are the pressure you're running.

Yes, flow rate input. I think I have a viper pump from the mid 90's. I should really take it out and look. As for psi, my engine with the super60 will never see more than 22psi anyway so I'm thinking I'll be fine.

contraption22
12-07-2011, 01:43 PM
I agree with Reeves about running low PSI when running high boost numbers. I do that myself running 83lb injectors and running 40psi of base fuel pressure. I was assuming Mike was going to be sticking with relatively low boost.

Back in the day before people were able to electronically tune their cars, people were running 25psi or less fuel pressure so they could run +40 injectors on stock cals. It would run ok, but it never seemed to idle very clean. I attributed it to injectors that didn't spray correctly at such low fuel pressures.

Mike, I just read through this whole thread as I finally found the time. I'm happy to see a very nicely executed and looking car all in the same package!

Some things I thought I would mention... when everyone is doing these fuel calculations for injectors, are you remembering that Chrysler is strange and flow rates their injectors at 55 psi instead of 42.5 psi like the rest of the world? That will highly alter your ultimate DC range calculations.

Also, be sure to monitor your actual fuel pressure under boost. When you have the ability to alter your fuel curve on demand, people often start to tune out mechanical issues... say an old pump that is losing volume/pressure at upper rpm or boost levels. You end up with a strange looking fuel demand in the upper RPM, but a powerband that doesn't seem to say the same thing.

Just some thoughts! Love the build, car, wheels, all of it!

Take care!

Thanks Aaron. I wasn't aware of the different flow rates, I'll look into that to see what it means, lol.

Do you have any suggestions in best way to monitor fuel pressure under boost? Can I rig something up to have my EMS system monitor that or is there another method?

Thanks for the compliments. I started with your block as the foundation and built around it. After I get a few more miles on it, I'll slap a bigger turbo on there and put that block to the test.

Chrysler rated their injectors at 55PSI rather than the 42.5 or so that other companies used. Thus, other injectors which you buy would be rated at the lower pressure and flow much more at our 55PSI static setting. It's something you need to take into account.

Cordes nailed it. The 52 pph +40's are not really 52lb/hr injectors per the normal rating system, so in turn your calculated IDC would be quite wrong.

Yes, you need an available 0-5V input on the EMS to be wired to a pressure sensor tapped into your fuel line pre regulator. The sensor will either come with a scaling of PSI vs voltage, or you will have to make one by setting the pump to different pressures and monitoring with a needle gauge to calculate the table.

Thats ideal. If not, ghetto version is a long fuel line T to a pressure gauge under your wiper blade. But ghetto style doesn't seem to suit this build. :)

the only way to tell is to have your +40s flowed.

there area some freak 40s out there that will flow almost 550cc at 45psi

so they turn out to be +50s at the 55psi chryco rating.



Mike, your running a standalone system correct? just keep the fuel pressure at the proper pressure you need, then make adjustments through the cal...shouldnt really be a need to raise or lower the fuel pressure when you can do it yourself through the computer by compensating with the fuel tables.

unless you know you are running a high volume/high flow pump thats rated for high pressure, its best to run your base fuel pressure as low as possible. Id suggest a bosch 044 fuel pump, as they are much more linear and are rated at a much higher pressure then say a 255 walbro......im pretty sure the viper had a high pressure pump tho?? might even be the 044 for all i know lol

---------- Post added at 05:55 AM ---------- Previous post was at 05:54 AM ----------

when i say linear, i mean that the flow does not drop off as hard after it reaches its maximum flow at the pumps rated psi......

wallace
12-23-2011, 07:46 AM
You can log fuel pressure with one of the electric Autometer fuel pressure gauges if your standalone will take a 0-5v input. You have to add two wires to the back of the gauge. I use a LM1 with auxbox and log fuel presssure. You can use the same sensor and gauge and also log backpressure at the turbine, just need to run a couple feet of 1/8" copper tube to keep the heat out of the sensor. HTH.

Because I bought Steve's GT3076R I decided it would be a good idea for some more safety improvements.

Plans are for a full cage out of mild steel right after it gets out of paint / body shop.

http://www.rollcageguy.com/

I'm cutting it close for SDAC completion but if all goes to plan we'll be there.

Edit - the GT30 will not be attending SDAC, the Super60 will. Hopefully we'll have the cam installed thou.

Why not a chromoly cage? They are lighter and stronger than mild steel, plus the properties of chromoly I think are a bit better for crashes as far as yielding and such are concerned.

I've heard that it's best to stress relieve(?) the crmo welds by heating them in a oven or some such after being put together and that failure to do so can lead to cracked joints when stressed? Any truth to that?

I thought (and I could be wrong here) that SCCA and NASA both mandated mild steel, which would be important for a road racer like Mike.

sy2206
02-09-2012, 06:15 PM
I'm not sure about NASA, but SCCA does allow it. Quoted from their 2012 rule book, "The roll bar hoop and all braces must be of seamless DOM mild steel tubing (SAE 1010, 1020, 1025) or equivalent, or alloy steel tubing (SAE 4130)." 1020 being the mild steel, and 4130 is the chrome moly. Because of the improved properties/added strength of the CM, you can run a little thinner wall. Mike and I ran some numbers last night. These figures do vary slightly depending on where you get them, but these will get us in the ballpark. 1.5" diameter .120" wall MS weighs 1.93lbs per foot. 1.5" diameter .095" wall CM weighs 1.37lbs per foot. So you're looking at roughly a 41% increase in weight going with MS over CM. Again, these numbers seem to vary slightly, when we were talking last night, we figured a 35% difference. We also figured a 6-point roll bar would use roughly 38' of tubing, and a 6-point cage would use about 54'. So here's some weights.

CM Roll bar, 52lbs
MS Roll bar, 73lbs

CM Roll cage, 74lbs
MS Roll cage, 104lbs

There are some other advantage to the CM over MS. However, the biggest disadvantage, cost. The CM is a fair amount more then MS. The roll cage guy said 80% of the cars he does use MS.

02-09-2012, 09:05 PM
I couldn't justify the $1g difference in cage price for only a 30lb weight savings. Not a bit worried about the steel cage being "stiff" enough. I think it will do just fine.

See, to me that's a lot of weight, especially since most of it is being added above the CG. Maybe I'm just overthinking it. BTW, I agree that the MS will certainly do the job! I never questioned that. :thumb:

Cost is a major factor, however, and I can certainly see why the choice of MS would be more popular considering the cost increase vs. the weight savings. Then again, how much do we spend to try and find 30# of weight to take out of the car sometimes? That's the way I look at it.

I'm not a 1/4 miler either. I'm looking at it from a standpoint of making the suspension work harder and saving overall weight. I know 30#'s isn't a whole bunch, and that some of our intercoolers weigh more than that, hence my comment on overthinking it! LOL :thumb:

The news on Chrome Molly isn't all good anyway. Yes we know it saves weight, yes we know its stronger BUT its also much more brittle than mild steel and is suseptable to stress cracks. If you do a lot of road racing you may even be replacing your cage after 4 yrs of track time. Then at best your replacing sections of your xage and at worst your building another 3500 cage. Have fun doing that.

Ironically, a cage that is BRAZED together can be better than one that is welded, due to the brazing material allowing for some flex, as well as the lower heat needed not causing embrittlement of the material... I seem to recall some Off-Road trucks going that way due to the shock loads...

I can imagine it befuddling a few tech guys not familiar with the technique though! Probably think it was a "redneck" move...

The added cost you guys speak of on the CM cage vs. Mild Steel....this is probably a lot of the added labor cost of the TIG welding vs. MIG welding correct? I don't remember the CM tubing costing a whole heck of a lot more than the MS tubing.....yes, more expensive...but not THAT much more.

They use brass and silver but also use a lug to hold the tubes in place as well. Often will drill and pin the tubes tack them and align the frame. Then braze to complete and realign.

I'll be applying clear bra to the important areas such as hood, bumpers, side mirrors, rear fender flares and roll cage

I thought people were saying NOT to powder coat wheels because the curing temps for the powder coat could anneal the aluminum, ruining the heat treatment.

I thought people were saying NOT to powder coat wheels because the curing temps for the powder coat could anneal the aluminum, ruining the heat treatment.

Ah, the great debate....Lots of info on this subject and I have a few concerns about this concern.

1) How do businesses that powdercoat wheels stay in business and not get sued when everyone breaks there wheels and crashes as a result of aftermarket powder coating?

2) Yes, I understand heating a wheel at 400 degrees for 15 minutes will change the wheel chemistry but no where near enough for me and lots of other track go-ers to worry about. You have to heat the wheel at that temp for something like 5-7 hours to put the metal into a t7 catagory.

I've read the posts that say they have broken there wheel after powdercoating. What some don't tell you is that they ran off the track and broke the wheel, then blame it on powder coating.

3) What happens when wheel repair shops widen a wheel or make one less wide? They weld it at an extremely high temp and then give it back to you to race on it!

So while others will never powder coat their wheels, I fall into the category of if done properly, I will not worry about running a aftermarket powder coated wheel.

Would I give my wheels to a powder coating shop that doesn't specialize in wheels...NO...They might heat it to 900 degrees and then you have trouble. Low Temps for a short period of time, proper heat build and cool down, IMO you'll be fine.

So for what it's worth, I will only trust a reputable wheel repair shop to powdercoat my wheels.

This subject is like Politics, no right answer and everyone has an opinion.

By the way, these wheels are for street / autocross use. My Traklites are for high speed track use. My powder coated Centurian I's are for show only.

While I haven't read the opinion of a metallurgists or experienced engineers on the subject, I'm still going to disagree. We are not pushing the boundaries of physics to understand what is happening in the process and there must be a ton of guys who know the real answer. It'll just take someone willing to do the digging or pay someone for their time to hear what the score is.

Cordes - I'll let you fund the wheel powder coating research project. For myself I have the info I need to proceed. Besides there are way too many variables involve like. Current makeup of wheels - how were they made (shot peened, heat treated?) Density of metal ( any air pockets in current casting? Then how are they powder coated - process, then how are they used? Track / street, etc...

I'm sure any metalurgist will tell u when you heat a wheel to 400 degrees its composition will change - the answer to the question is by how much and that has to be done on a wheel by wheel basis as they are all different.

Illinois tell you this much, if a nitrous bottle is heated over 350*F it must be decommissioned (have a hole drilled into it), because it could have been annealed. I suspect wheels are in the same boat.

That said, if they were cooled properly they could be essentially re-heat treated and be just fine. Some powder coaters may be aware of the issues with aluminum and do this process. Also, OE wheels are so over-built, even weakened they aren't in danger of failure ....

Pickup wheels outside of Philly on Saturday, drop off in Bath PA 2 hours later. They ship em out yesterday and I get them today. That's a nice service.

1 of the wheels was slightly bent, they straightened it and I had all 4 powder coated in a Audi Grey. It's pretty close to what GM calls Competition Grey.

They have a light tan powdercoat base and a grey paint laid over top. It came out just like the sample Audi wheel. With the Audi wheel, you can see where light reflects its lighter grey and on the outer it changes to darker grey (that's due to the tan powder underneath).

The Traklites, the Centurians and the Buddy Club "fakies" may never get to come out to play. It seems like I say this everytime I get a set of wheels refinished I say there my favs. So I'll say it again, these are my favorites, lol.

Another wash, some glazing and then waxing and we should be ready for final assembly / decal install.

Also, Brian serviced my trailer yesterday and added a sweet electric winch. The winch is located inside a tool box installed at the front of the trailer so it's totally enclosed.

Thanks to Brian who knocked my list out in 4 days! After installing the cam, according to the butt dyno we picked up some mid-range torque and it had a smooth curve, power came on steady and constant. Couldn't really let it out where we were so when I get it to the track, we'll test it at 14 psi and compare it to the 88 stocker.

The thrust bearings solved the coil bind issue. Thanks to everyone who recommended those.

The MBC Chad T installed last year works as advertised. We had to swap the stock spring out for the heavy one to get it past 15 psi. But with a ----pit controller it really couldn't be easier.

I asked about that and the seat are designed to have the belt come over the top around the head rest and there is a provision (extra cost) to have a 5 point belt come through the middle of the seat, which I got. :) I figured if I ever use them for a car that has a cage or if I add that to this car, I'll have the provision already there. When I get the seats I'll post pics of the top. Still wondering about that. I DO know that the head rest are interchangeable with some of the older Recaros, if not all of them. Which is nice because my friend has a set and the Saleen seats that have the mesh net head rest work in them as well. But I am with you about the pass throughs, kinda wish these seats had that style.

I'll eventually fill in the space with something attractive, probably metal in color so it sticks out and kind of matches the color of the headlight it replaced. Why no gains on a turbo car? I would assume the more air (especially clean air) the better.

^ The turbo is like a giant vacuum cleaner, its going to suck air no matter where it is, the cooler air will help some. I think a scooped air box under the front air dam may be more effective. Your car is so good looking I would loose 10 hp and keep it looking that way.

GLHNSLHT2
05-14-2012, 12:39 AM
Yes but if you can give the turbo more low vaccum or even pressurized air it becomes more efficient. It's like adding a turbo in front of it in effect. Just like Compound turbo charging. The easier the turbo can grab the air the more efficient it will be and the more power it will make. Put your hand over the end of a vacuum hose, the thing still sucks but no air goes through right?

fishcleaner
05-14-2012, 01:25 PM
^ I know the point you are making but every thing I've read on scoops it's really the cooler air that makes the difference over any air presure. First you have to confirm the headlight bucket is a high pressure area, I know on some Vipers the NACA scoop on the hood at very high speeds actually suck the air out of the airbox. The only way to know for sure it to make a few passes at the track and see if the times drop. NASCAR teams have forever pulled air from the cowl area because its the highest pressure area, Omni's have a great big cowl that could be turned into an airbox, something to look at anyway.

Sorry it's pretty dirty, hadn't washed it in like 10 minutes.

Thanks. Unfortunately I worked yesterday and today so couldn't join in the track session fun.

They (and the corvette guys) all loved it.

Most of the responses were, that's a rare Shelby and I haven't seen one of those in a while. This was a Team Shelby event so I think they welcome all things Shelby.

The guys at cars and coffee enjoy seeing it also. They want to hear the story about how this car came about.

I'be trying to figure out how to use the omni cowl to pull air from but can't think of how to do it as everything is in the way. Any pictures, ideas, dreams, suggestions, etc??

Thanks
Randy




^ I know the point you are making but every thing I've read on scoops it's really the cooler air that makes the difference over any air presure. First you have to confirm the headlight bucket is a high pressure area, I know on some Vipers the NACA scoop on the hood at very high speeds actually suck the air out of the airbox. The only way to know for sure it to make a few passes at the track and see if the times drop. NASCAR teams have forever pulled air from the cowl area because its the highest pressure area, Omni's have a great big cowl that could be turned into an airbox, something to look at anyway.

I'll probably sell a set and keep the rest.

Thank you. Here are a few from Cars and Coffee, Great Falls VA style

They had a Noble Turbo which if I were single would be in my garage right now. I'll try to get a good picture of it next week.

Alignment today and also hope to get a few runs on the Dyno to see where she's @ on 17 and 22 psi.

Update: 262 and 283 @ 17 psi, I'll have to double check data but I think it was about 10.3 afr so a little rich.

Couldn't get the mbc to work and despite Brian installing an ebc months ago I wasn't familiar enough with it to turn it on:banghead:. So for now I'll just have to wonder what it would have been @ 22 psi.

If I may bench race a little.......Does 262 flywheel = 300 @ crank, haha.

Will get familiar with ebc and try to have hummin for sdac.

A little! I'm running at 11.8 to 12.1 depending on how it feels. I'm pretty sure there is about 8 to 10 just there.
And as for the bench race.... 302 @ crank:D
