If you are STS and Stalled please come in
If you are STS and Stalled please come in Im currently installing and STS style system on my 04 GTO A4 and have a couple questions. I know all the supporting mods and must dos and must nots. This is more of a question about setup.
I currently am installing dual springs and hardened pushrods and going to run 60-1 on around 9 psi. This is a stock LS1 other wise. I also have a built 4l60e waiting to go in. My question is simple. what size stall would you think would be optimal. We are thinking on 9lbs i should be close to 500whp through the auto. atleast i hope, or i will turn it up till it pops;. lol
And also, do you think its good for high 10s at the track. Will be using 275 DRs for the track. i hope i didnt leave anything out. Im will be building a forged 370 all year, and when i switch engines next winter i will build a one off front mount. just curious of your thoughts on possible times. I will be running at Oreily Raceway park at indinapolis this year. (IRP), and they usually do a pretty good job of prepping the track.

60-1 with a .81 is the sizes of the turbo im using. Its coming off a friends car that dynod 500whp and 616 wtq through a 6 spd. And honestly, i was kind of leaning towards a 3200 stall. just didnt know what it would be like.

Thats a pretty small turbo !
prob wouldn't go to high on the stally with that combo, as it will be spooled up pretty early and will also sign off at lower rpm. You can tell by the high trq verses hp that the turbo is on the small side.
It would be usefull to see a dyno graph of power and torque to see where it was peaking.
Also converter will very depending on intended vehicle use, daily driver, weekend worrier, or race orientated.

run your car til you see full boost then go for something around there on avg most people see it between 32-3600. Without you knowing how and when it's going to hit with you set-up makes this kinda hard (so many variables). A happy medium would be a 3400 stall. What else do you see yourself doing in the future (transbrake, 2-step etc). I have a 3600 and I like it. The way it feels when you want to go is like a 6spd letting off the clutch to go, rolling with gas and obviously no clutch usage lol. You are going to be moving and going before your stall speed so it will just feel different at first.
no trans-brake, no looking for anything more then a 10 sec. street car. i have two other vehicles i drive through out the week. so if this one breaks, well, then it breaks. I was looking at his dyno graph. and it seems to hold the 508whp fairly well, i can see it dropping off ever so slightly maybe 25whp by 6000 rpm. so it is a little small.
Remember this only has to last me till next year
3600 stall seems big, although i have never driven a car with a stall, just seems big. i could be totally wrong though.

The reason I went as high as a 3600 is because of the motor and the size a/r I have. The reason from what I have been told is this will keep you in the power range when you are foot brake launching and will keep the rpms from dipping a lot when the car shifts. Give Yank a call and ask Dave what would work with your set-up I am sure he can help. Keep in mind that N/A motors are mostly in the 4000 stall area. But this isn't a DD so what would it hurt to have a bigger stall
About 3300-3500 ACTUAL stall should be good. That doesnt mean that an off the shelf 3300-3500 will actually stall there. You should talk to the guys at FTI.
Also, start saving for a new transmission because that's about where they die.

I'm running a 3000 with a 67mm .96. I love it and it runs great. Car is mostly a street car though. I dont see you hitting 10's with this setup. I could see mid 11's if you can keep it all together.
