I really did not have any where that I could check to see were the converter was flashing to. I did pull the chip out out the low side on the 2 step and the converter went to 4800 on the trans brake. The only chip I found close to that was 4100, so I installed it and tried it. It just made the wheelstand worse. It actually went on the rear bumper. It caught me off guard and I lifted instead of shifting, as it was still climbing. It came down kind of hard and dented the pan a little. https://www.youtube.com/watch?v=U1N066LYGyQ I played with the launch RPM and ended on 2500 rpms. The car left good, but is pulling to the right. I added some preload to the passenger side, but when I went to make another pass I noticed I now have a water leak at the radiator. I guess when I came down it twisted the radiator a little. I will try to find a shop to repair it and head back out on Sunday. https://www.youtube.com/watch?v=TkidPFOvDyU Last edited by 416challenger; 02/16/13 01:09 PM.

Quote: you have the same problem I do, you better put some wheelie bars on that thing while your trying to figure it out. Add the longest wheelie bars you can and still get the car in the trailer and test till it looks like it is working well. Then shift weight forward (if the car isn't repeating like a machine)till the car is as consistent as it can get. Go win races. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Higher launch RPM 99% of the time is going to result in a more aggressive launch aka bigger wheel stand. This theory people say about leaving against the converter so it doesn't "flash" has never held true with anything I've seen. I've tried it many times in different cars with the same result. Keep the RPM low. And fix the turning right issue (add pre load). -Dustin 67 Dart, 9 second, 392" G3 Hemi 68 Barracuda 340 F/SA

If not you better start making sure tire pressure is the same right and left, check track prep and car alignment, or see if the driver is some how doing it. PLEASE don't take this personal but when a car leaves the line like that you better learn not to get back in the throttle because either you are going to wreck the car, do engine damage, or maybe DAD with take over driving HIS car again. Its not worth it. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

If I flash my converter, i'm hard on the wheelie bars, but when I load it up on the stall, it doesn't hit the bars as hard. I'm not sure if it's because of the limiters I have on my front suspension maybe, after a couple of inches of rise, my car has to pick up the whole front end. but what you are saying isnt always true. I even put max adjustment on my bars to see, and it was the same. This may all change with his shorter wheel base tho.

The car obviously has other issues, it needs to go straight regardless of how high the wheels are in the air.

It was a 3800 lb car running 9.85-9.92's no bars, we went back to the shop and made a some corrections for the IC and got it to where it did no wheelies and ran the same times, with a 9.82 best run. 5500 0n the stall and transbrake.

It works on all the foot brake cars I've raced BUT, I haven't raced a trans brake car in a lot of years, soon to change sometimes you have to go the wrong way on testing to find out which way the wrong way is Never rule out trying something old on a new problem, what works on one car usually work again in a similar situation Mr.Cab Racing and winning with Mopars since 1964.

Works on my car but I have to vary the tire pressure to work on different tracks... a 1/4 psi to 1/2 psi to control the lift and get the tire speed to what I want.... I leave on the conv all the time... but Tony might have to move the IC back to keep the front down NOTE the pic in my sig is for pics not the way it leaves on the normal basis EDIT even here I needed more air.. I was a 1/4 psi low 7591200-5-108.JPG (138 downloads) Last edited by MR_P_BODY; 02/16/13 11:43 PM.

I agree with ya, My car has pulled a few hundred big wheelies and I can tell you that the higher the launch RPM the harder it gets up on the bumper. http://youtu.be/fAP_2rxz_GA
