what times do you think i should run??? any guesses are good I finally have things falling into place and have pretty well all my troubles figured out but I'm wondering what times you guys are running or what you think i mihgt run. Stock bottom end ls1 with 6.0 heads running 60# pounders with an sts system runing 10-14 lbs. custom tunning of cource and some stickies out back to transfer power down hopefully they should eliminate all wheel spin. 3000 stall to spool online but other than that I believe its only having to push 3056 lbs down that 1/4 mile any ideas as to what time would be seen?? any guys out there that have a similar set-up and what are your times thanks

If you do everything right, you should see mid to high 11's at around 120ish

What trim STS? 60 or 67? That is allot of boost on a stock bottom end!! Oh and if you have a stock rearend... you will break it verrrrryyyy soon. But you can see my setup is not much different than yours... and in 100% stock trim with an M6 I ran 11.6 on ET Streets... you should do better with an A4 and a Stall.

yeah sorry about that guys i forgot about the suspesion and stuff ive done i have a 9" out back now and 0/90 front shock and 60/90 rear shocks so i have some really nice transfer now other than the rear end i have bmr lower arms edlebroke adjustable pan hard and torque arm. And I didnt think 10-14 lbs would be too much with the C/R now around what 9.2 i think it is but maybe you guys are right haha who knows till she blows. thanks for the feedback guy hope this really puts the power down properly but i guess i have to face the facts tens will be done on my new bottom end i guess. thanks and if there are any other ideas on how to get there please feel free to speak up and yes i have thought of juice but not sooo much of a freeby hahaha thanks again guys .

if it's tuned right and you can manage a 1.7 or better 60' and you have the 67 turbo is should go 10's really easy.
My car was trapping 124 consistantly at 13 psi on 2.0 60's. I would only manage 11.7's due to boost response and my lack of ability to launch.
The amount of boost you can run safely is directly proportional to the tune, octane and how smart you are. The lowest boost my car sees is 10 psi on 91 octane with just a tiny bit of meth for some extra safety.
If I put 6.0 heads on my stock motor and was still 6spd i'm confident that 700 rwhp would be easy to get and safe. I might crank up my boost to 18psi or so with the new auto on some 110 or 117 in the near future. Most i've run so far is 15psi which should have put me around 675 to the wheels. Never ran at the track on the t76 though. I can tell you that I've pulled several liter bikes from 65+ though.
How long your motor lasts is really dependent on the tune.

im actually going to be running a t70 not the 67 or 76 so im was just wondering from what i hear they are pretty good for spool time and what not so i guess i will have to wait and see . thanks Zombie ....... were u honestly pushing 15 lbs on stock compresison and motor?? wow thast some crazy tunning im guessing wow but good to hear that it can be done... I was also reading around this place that the number & cylinder is the biggest cause of failure in these engines ringlands letting go ???? hope this isnt true for all motors they put out but it seems alot of ppl have had this happen, what causes this just faulty casting or is there a clearance issue?? anybody know ???

I believe they say # 7 lets go due to poor fuel distribution. Apparently 7 gets less than everybody else? Thats why alot of folks say tune richer than you think you should.

I just tuned another stock motor car and he made 500 rwhp and 600 rwtq at 4500 rpms with a 67 turbo and 14 psi. We couldn't get the rpms any higher due to massive wheelspin on the dyno.
