[Sundance 6g72]

Im going to use this thread to post updates of our progress at drag week in a few days! I have my moms cannon camera and as far as i know its decent enough to get some videos of Ed's shadow screaming down the track

What do you guys think the car will run on ave?

heres a mod list (if i can remember them all correctly)

MS II
Custom twin plenums
dual 80mm Throttle Bodys
Powered Heads
Crower Regrinds
Light flywheel (not alum)
Custom Half header
3inch exhaust
no major weight reduction
street tires
a543 trans
VE table seeing values as high as 104 ! !

17.5 :P

Just ball busting - I hope this thing runs fantastic for you guys, and blows the expectations of some onlookers right out of the water! Represent the NA Pbodies!

I'll say high 13's, low 14's.

Well I don't know that Ed has a lot of passes under his belt and not sure about the tune.

I would think the trap speed would be very good if the tune was on. 100mph capable.

we made it to Topeka ks!!! but not without issues

lots of rain, TPS sensor went out momentarily on the truck, we forgot a laptop and we dont have the cable for my camera to upload pictures. Not to worry, we used my laptop and confirmed that it works with Ed's megasquirt and the car is running great. we also fixed (so we think) the wideband issue by updating the firmware (LC -1 2.0 beta firmware, you need to do a bit of looking to find it)

tomorrow im going to try and buy a usb cable for the camera so i can get you guys some good picture and videos!

[Vigo]

Yeh, pictures are important. Good luck out there!

[turbovanman²]

Good to hear.

What does the LC1 update do? Link?

[Sundance 6g72]

i meant lc 1 firmware 1.20! not 2.0

it fixed the gauge from dropping out and giving us a huge rich spike

pics in a second.. ill have more as days go on.

www.photobucket.com/dragweek6g72 is the url pics are being uploaded to as we speak

So is that old firmware? or brand new release?

[Ondonti]

Saw those on facebook. Ed is non longer flying under the radar.

I like the front half header.

So what is he running?

[Sundance 6g72]

all the runs are no good. should be low 14s easily but without slicks its tough. every run got better though. we went from a 16 to a 15.3...... car did make 170hp to the wheels (i made 147 and 15.3 is where i should be!) but not sure if slicks are needed

i know the record is at 14.2 but that is with less mods plus he had slicks. car is running 90mph though. i think the best 60' was 2.2 it was much worse.


right now we have an issue though. seems like the car runs VERY lean and starts bucking (afr goes from 18:1 - 21:1) and then it dies. this happend twice in hot temperatures and a long drive. we havnt had it happen sense though... we need help making sense of the data log.

shouldnt be to hard to find where the issue happens.... it goes lean and stays lean. the lean spikes earlier in the log might be when the throttle is lifted. when it goes super lean we kind of jumped on and off the gas so that will explain the tps going up and down. not sure if its fuel or ign related and its hard to tell when he problem just disappears..

if someone could take a look and give some input!

Do you have a fuel pressure gauge with you? Worst case, somebody out of that whole bunch of racers probably does. I have had multiple instances of the pump strainer pulling enough silty debris up against it to choke the pump and become a lean problem. When the car sits, some of it falls back off, and then when driving again it sucks it back up. The same thing can happen with oil pickups and trans filters in motors and trannies.

Just an idea.

I dont know how to view the log.

[turbovanman²]

Sounds like you had fun, too bad it didn't run as planned. Do they ever?

[Ondonti]

Confused. Is this happening when racing or when cruising around.

90mph is not good.
I did 88 on an almost stock 3.0 with a604, ported plenum and spacers, exhaust cut off after cat, 52mm tb and CAI and new magnacore wires. That was only a 15.48 E.T., so if you went 15.3 on a manual trans that is harder to ET vs MPH, then something is going wrong.

[Sundance 6g72]

we have a fuel pressure gauge but it reads fine.. the question is, does it read fine when the problem comes back

every race went fine.. just slower than it should be. It only happend twice and that was when cruising and when we had it idle it still was crazy lean and then died. its hard to make the problem come back though...

we are looking into the fuel pump and fuel filter.

tell ED to stop running 31 degrees. Run 40 or more degrees total. He already proved on the dyno that an OEM style 3.0 makes more power when you go from 38 degrees to 41 degrees (+3 degrees base). Now, why is he running 10 degrees less. My cars are always turds when I do that. He is so far down on power.
He needs 12.5-13.0:1 AFR and lots of timing.

One thing I have never had trouble with is running fast when I want to, even when I bring a knife to a gun fight.
One question I have is what gear are you guys ending in. If you rev to 7000 you don't need 4th gear. Are you short shifting and killing power, or running out of power in 3rd...I am thinking you need 4th because I bet you have tiny 50 series tires on there also.

[87turbodance]

I see AFRs in that log mostly range from 16-20:1. Seems very strange. I'm wondering if your info from the wideband is wrong.
