Hey guys, Ive been reading how some guys have upgraded to a 4000rpm stall from 32-3600stalls and have been very happy with the change. I was wondering if thats what I need. My car is a LS1 with forged pistons and rods, stock crank and a 237/243 112lsa cam. This setup was meant to be fast hi revving which it is...from a dig. I feel that the acceleration suffers a bit from a roll. I have a Yank SS 3600 with 3.42s. Im afraid this might just be me geeting use to the cars speed. The car is slammed to the ground yet get 1.60ft times and run the 1/8th at 7.283sec @ 96.58mph. I have yet to run the 1/4 with the tuning and setup I have done. Would stepping up to a Yank PT4000 make a difference or not enough to justify the price of the new tc plus install?... Also, maybe it wants more gear?

You are ok on the gear.. et and mph matches.. sixty foot isn't amazing. are you spinning?

If you aren't planning spraying I would move to a 4400, if spraying stay where u are.

That should get you in the high high 1.4 range and get you some 6.9x passes.

Yeah I was breaking them loose and did get a little wheel hop at times. I thought of nitrous since the motor can handle 150-200 shots all day but Im not too serious about it. All motor performace is my main concern.

I thought a little 100-150shot off the line would be cheaper than getting a new stall. Lol.

before you make any more decision i would make sure you are dead hooking. What tire setup are you running?
Just going from 1.60 to 1.55 will take you from 7.25 to 7.15.
since it an handle it i would seriously consider it.. You could talk to a sponsor and have them get you a 4000 nitrous converter.
You can easily have 700+ in a nitrous kit before you know it, mostzly buying used part too. Lol

If all you really care for is all motor.. put a 4400 in, you wont be sorry. You need to get the car hooking though before anything.

I would just keep the converter you have and put a kit on it, you will be MUCH happier in the end

Thnx for the advice guys. I thought about it and you guys are right. Idk if all that work to change the tc would be worth while or if it would be enough of a diference to make it worth it. I already have a window switch setup for my water injection that Im sure I could easily hook up a no2 kit to. Any recommendations on an easy setup or system?

I can't believe I'm the first to say it. It's a stalled automatic, of course it is going to do better from a stop than a roll! LOL

My car ran 7.20@ 97mph with 1.601 60' with a cam pretty close to yours with a Fuddle racing 3600 nitrous converter. I got the car to run 6.90's N/A with 1.47-1.49 60' and do you know how?

I'll start by saying I never touched the converter, I bought adjustable drag shocks all the way around and some half decent adjustable suspension parts and tweaked the suspension until I dialed in the 60'. I would highly recommending putting your money into adjustable suspension and especially some good shocks and get the most out of your setup before you go changing things that may not necessarily be the issue.

I'd be willing to bet that you didn't accomplish this with a 3.42 gear in the rear end. I agree that the car needs to hook consistently before changing anything and the wheel hop issue definitely has to be fixed.

I would approach the car in this order: maximize suspension setup, lower the gear ratio, then up the converter stall speed. I wouldn't recommend running a 4000+ stall speed with less than a 3.90 gear ratio. The motor will get "up on the converter" and lag there until the wheel speed catches up.

342s can get him deep into the 1.4x range, possibly even 1.3x with a good dialed in setup. Autos don't need a low ratio to cut a good short time.
I would look at suspension... then either converter or nitrous.

Thats exactly what I was going to say. If you want to do better from a roll then get a tighter stall, or just swap to a six speed. Stalled auto's suck from a roll. If it were me, I would leave the stall and start upgrading your suspension as mentioned above. If your not hooking up now, your damn sure not going to with some nitrous.

I guess my oad racing suspension isnt the best for drag racing. Lol
