SoCal Dyno day-the La Carrera GLHS runs-finally.

[ForzaV12]

Chris @ TU was finally able to twist Paul's arm(with a lot of help from the socal crew) and get him out here for a dyno day. Last time he was out here was in 2004!
Unfortunately for me, I had completely redone the infamous La Carrera, Sublime GLHS-new 2.2 with IMSA crank, rods, custom lc pistons, cnc'd head, GT30R, TU header, 3" SV, fuel rail, 3" side exhaust,568 w/quaffe, custom axles,etc.
It has always had a "baseline" cal in it and would never really run properly, so it basically sat in the hanger except for the occasional run up and down the tarmac to keep things fresh.
I arrived early Saturday for the dyno session. My car was on the dyno for three hours and probably made 20+ runs. Paul(and Steve-the dyno owner) kept working the fuel curves, gradually built up boost,etc,etc and finally had a cal to test.
Just for some background, I wasn't looking for huge HP numbers. While this combo should easily hit 400hp, it makes no sense as traction is limited for road course action. My primary concern was reliable power and quick spool for road race use. So, my boost levels were about 21-23lbs, combined with a bulletproof bottom end and low compression it will(hopefully) run for many track hours on crappy pump gas.
Even at those low boost levels we still obtained about 300HP at the wheel. When we first took it out for a test run, the drivability was great but as soon as you got into boost it would go pig rich and stumble badly. Back to Paul-he expected this and reflashed the cal for the partial boost mapping. Back out for a drive. Bottom line-this car is now fast-figure 360 CHP and a sub 2K weight! Pulls out of corners hard, spins sticky road race rubber in third easily and just wants to run.

We are really looking forward to the Team Shelby Bash in Vegas and look to have a little something for the Fords. Our little essentially stock Terlingua GLHS ran well last year, this should be an entirely new ball game.
If Alan gets the red monster back together, between him, I, Todge and John L. we should be zinging around the big V-8s like killer bees.

Once more, thanks to Paul who kept patiently plugging away for hours at everyone's cals even when there were some stressful events. I haven't heard from John L(two Omni cals) or Ed(reflash on the Daytona) to see how their results turned out, but I know that myself, Todge, Jeff(89 CSX) and the van all had great results.

Here are a few pics. Coincidentally, there was a collector in three or four of the industrial buildings next to the dyno shop. They were running quite the variety of cool iron in and out of there all day long. 409 Impalas, Lambos, Six pack Roadrunner, Superstock Mopars, Caddys, VW microbus, 427 Corvettes, etc. Pretty cool.

Would love to see that happen! Should make for interesting conversation at the event.

[Vigo]

Congrats on the good results! 300+whp in a <2000lb omni sounds like silly fun.

Also glad for the big pictures of the van.. im considering a similar color for my spirit so it gives me something to state at and ponder..

[168glhs1986]

Nice build, sounds like you have a monster on your hands What intercooler are you running? If front mount do you have any pics? So this is the cal from turbo's unleashed? Did it really take 20 dyno pulls to tune it? Being from the east coast, I won't have the luxury of tuning in person

[turbovanman²]

That's very cool and yeah, it can take 20+ runs to get a cal dialed in.

That's what we are hoping-the Hero in car video should provide some entertaining footage.

There was an original 70s Mopar paint code that was close-with a bit more impact-might be cool on the Shadow.

IC is an ancient Sparco(it remained cool to the touch throughout the dyno sessions. The cal is a TU/Paul set-up. Yes, it really took that many pulls. Paul didn't take more than a 10 minute break for the 10 hours we were there. Super stressfull for the programmer-understandable that he doesn't want to do it very often. Although, I'm already hoping for another session for the black car!

That's very cool and yeah, it can take 20+ runs to get a cal dialed in.

Thanks, I was surprised that it took that many pulls. I'm old school and remember changing jets, power valves and timing on my musclecars. Usually was good to go after a half dozen pulls!

I had a lot of fun although it made for a long day. Very impressed with Steve's car. I was hoping to get a bit over 200 whp. Just have to figure out what I did wrong. Would having the tall tires make a difference in numbers? Everyone else there had short tires on their Omni's.

[glhs727]

Post up your dyno graphs!!! lets see the hp/torque numbers and a/f's too!

What kind of dyno was used? did it have an eddy current brake feature? sounds like it was an inertia style dyno if you had to road test for partial throttle.

Steve,
with that imsa crank, what kind of rpms does it pull up to?
so if I understood correctly, you made 300 whp and 360 crank horse power (chp?)

So is Paul the TU "calibration technician"? was he using D-cal? what happened to the new fangled tuning software stuff that was presented at SDAC by Ken? or was that what Paul was using to do all your tunes?

sounds like you guys had fun!
later,
Cindy

The difference would be pretty minor. What are the mods on your van? Is it posted in another thread somewhere? Nice paint color btw

[DocFish]

I don't have a way to post the dyno sheet. I hope maybe to fax it to someone and they could post it!?! Plus, I didn't want to hijack Steve's thread, but I will. Stock 2.5l bottom end, Super 70 w/quickspool and .63 stage 1, ported head with +1s (self ported, that's probably the problem), 2-piece with 52mm tb, ported stock exhaust manifold, 2-1/2" exhaust with no cat. 3 Ford Supercoupe ICs welded together. Paul said the IC probably wa working very well as he'd never seen a 2.5l that wanted more fuel on the top end. I guess it really wanted more fuel and timing from what I gather. Oh, this was at 18 psi. Didn't run it any higher. 196hp and 242 ft/lbs

Those cars are a work of art! Congrats on the new tune

what size injectors?

[DocFish]

+40s..

[glhs727]

really? yea....seems something is wrong, 196 whp with a big turbo, IC, ported head and you should have MORE than enough fuel with the +40's... well I hope you get it all worked out, that van is pretty cool looking! Vigo!! hurry up and get you van painted and do Mason's while you are at it!!!

I made a quick post in Lynn's thread, http://www.turbo-mopar.com/forums/sh...ad.php?t=44717, but I'm pleased to elaborate here.

I had two cars there - stock 86 GLHS and 85 GLHT converted to T2; the GLHS' first pull was 185 HP and finished with 195hp @ 16 pounds while the GLHT first pulled/flashed 248 HP at 23 pounds but finished with 228hp @ 18 pounds.

Both cars were dyno'd on Chevron 91 octane.

The '85 GLHT, has a junk yard 2.5 longblock with T2 stuff bolted onto it - TU's cast exhaust manifold, hybrid, ported 2 piece IM and FMIC. I think we went backwards but in a good way; first pull (I saw it but - no print out to confirm) was 248HP at 23 pounds but detonation on all 4, we turned the boost down and then Paul marched it back up until knock commenced at 18 pounds on cylinder #1 only and he couldn't take it any further - looking at cast pistons. I suspect that a weak injector on #1 is what stopped us.

As for the 86 GLHS, I soldered the 3 BAR weatherpack connector to Paul's socketed '86 LM board so the map sensor can stay under the kick panel. It is not an '87 CSX cal which is a tad faster but would require swapping a couple of pins; this way, I can stick a stock 2 BAR 86 Shelby cal back in it at any time without needing to change back the pinouts. The car has +20s and 2.5" SV/downpipe/cat. Other than that all stock. Same issue, Paul couldn't push the boost higher in the face of crummy gas and the risk of cast pistons. Fine with me. I appreciate his conservatism.

Both tunes are safely rich. Leaves room for me to . . . . .

Driveability of both cars is much improved.

Lastly, I thought I smelt race gas during the course of the day. I brought 5 gallons of unleaded 100 but we ran out of time so I did not get to play with it. I wasn't happy with how I was deprived of that opportunity . . . .

[DocFish]

John, I didn't realize both Omnis were yours! Do you road race both, or just one of them? Hope to see you guys in January.

[BadAssPerformance]

Cool story and pics! I love your Slime Green GLHS Forza!

[johnl]

John, I didn't realize both Omnis were yours! Do you road race both, or just one of them? Hope to see you guys in January.

I have never raced either one of them but both cars have done track days.

This January will be the third time that the GLHS has done the two day Shelby Bash track days. She has also done track days with the GT40s at Willow big track and and Streets.

The GLHT has done track days at the big track only. Last month Alan tried to get me out to a track day at Fontana . . .

The Ramerati did a track day with the SoCal Mopar Spring Fling at Willows big track too. That was fun, the trucklet flyin around with a bunch of growling screaming V8 Mopars.

It did'nt even occur to me to get the graphs-I was so excited after the final test drive that I forgot all about them. Long day, as I picked up the car at the hanger at 6am and didn't leave the dyno until after 6pm! I don't have a clue what dyno it was-you could check the dyno website. Car pulls hard to 6500 rpm with no let-up in power. It should be safe beyond that with the custom pistons(lowered c.r. and other goodies), IMSA crank, etc. As I mentioned earlier, I wasn't looking for big power numbers(numbers you mentioned were what we saw) as they are really pretty worthless for my application(and without drag slicks).
I don't know what software Paul was using, but he was busting his behind to get the tunes correct. We were able to watch my A-pillar mounted Innovate wideband during my runs-interesting stuff!
You and James coming to Vegas?

Those cars are a work of art! Congrats on the new tune

Thanks-very excited and I have quite a few tricks planned for the car(both cosmetic and functional) that I plan to get going ASAP. I just wasn't too motivated when the car had tuning issues.

Good numbers and if last year was any indication, we know you'll be turning up the boost!

Thanks! Wait until you see what I have planned for it.

somethings wacky, my 2.5 made 198/280 at 12lbs with the 2 piece, cummins i/c, stock head, ported exhaust, +40's and 3" exhaust.
