yeah they are a 26" MT ET street, which is the reason for hitting 5th...I go to the track maybe 3 times a year so i dont see buying another set in the future for me..I plan to go to the track this wednesday for the last time then sell my tires...I cant bump my limiter without a flash and really im not a fan of bumping the rev limit and F/I on a stock block DE..scary stuff

the whole thing comes down to being worth it to me..i could do this and im sure it would be great and have thought about it many times and would net me better times, but i would have to get the flash to bump my rev limiter which isnt cheap..around 5-600 bucks, then i would have to drive 4 hours to get on the dyno and re-tune for the added rpm's which isnt cheap, and honestly i dont know if i would have the fuel to safely run out that high, so i would probably have to add larger injectors as well, all to be able to get thru the traps in 4th gear maybe 3-4 times a year and pick up a little more power up top is probably not worth it to me, i think im done with the track after this next time wednesday and plan to sell the tires anyway..I plan to start another project car pretty soon for a track car (top secret)

Well, regardless...I think adding 109whp to my car is no joke so I'm happy for now. I'll get some cash saved up and add an exhaust soon with some other mods and slap on a 2.87 ( which I already have on the way ) and see what happens.
Thanks guys.

what year is this car? If ur revving to 7200 i dont see how people can say those numbers arent low..I make 420whp/355ft. lbs on 9-10 psi...(3.12 pulley) with just minor bolt on's on a dynojet...big difference in numbers and im only revving to 6600???...5AT is not gonna suck that much up..Only difference there really is i have an exhaust..idk seems weird to me but guess not..
IMO the OP is making exactly what he should be for his supporting mods and non revup AT.

Just curious, what did you do for your fuel delivery? Did you upgrade your injectors and swap out the intank fuel pump, or did you use the Vortech FMU that comes with the full kit? If you are on stock injectors that may be the reason for your numbers. I think they are only 290cc.

You made 420 rwhp with a 3.12 pulley on a non revup? what additional "minor" mods do you have? I had a revup using 2.87 with catback and then was able to make 440 @12 psi (on a dynojet). Just yesterday dropped my car off for retune. To get away from high PSI's i installed Stillen Headers, Stillen HFC to go with Stillen exhaust, and i went up in pulley size to 3.12. I am hoping to make a clean 420 RWHP @ 9 psi.

yezzir.. ur scared of 12psi???? why not just get the 928 valve that bleeds off boost...u could stay with the 2.87 to bring the boost in sooner than the 3.12 and bring more torque in and bleed off anything more than say 10-11 psi or whatever u are shooting for...thats what i would do

my numbers are on a dynojet..I have been on 2 dynojets and 1 dynapack..the first dynojet said 408whp/345ft. lbs. and the 2nd dynojet said 420whp/355ft. lbs, the dynapack was waay high....this is at 9.5-10psi..take it for what it is but both are pretty close..the trap speed shows the power is there so really dont know how the numbers would be high, also i am hitting 5th gear before the trap which is killing time and mph...
numbers are numbers, and ill be the first one to say that numbers are worthless..i just find it hard to beleive the stock exhaust is robbing the op like that..maybe though with the stock exhaust and the 20's and 5at combo it is happening..

Hmmm,
What ECU are you running.....wonder how happy some ecu's are gonna be with this bleeding off boost.
I didn't read up on it, but more importantly which way does it "fail"? By that does it fail open where it bleads as much boost as possible, or closed where it lets all boost go to motor?
just curious
