AJ had a sweet ride. Good luck on your tune. Jeff is an awesome guy and the shop does top notch work. Enjoy!

that he did, he has helped me build this car, started it up tonight and will be getting the tune tomorrow in the am. only thing that sucks is i broke a wheel stud while switching to my street tires... hopefully 4 lugs hold up.

Listen to Jeff. If he says it will hold for the tune, it will. If he says fix it, do so. The guy knows his cars and wont steer you wrong.

Looking forward to seeing your numbers. Get it early because it's going to be a hot week!

well my 2.5 pulley blew apart on the dyno, yes the pulley not the belt. im waiting on my sister to run my 2.75 up to me and it will be getting tuned on that as of now. what would you guys suggest to do to hit 700? also the car has 26x11.5 17 drag radials on it on the dyno so numbers will be about 30hp lower.

Is really hard to hit 700whp + on a 2.3 and the corn ... I think 04 sleeper has been the only one ...I know a local member that made 680whp with your set up with a 2.6 RR upper and 9:7:1 compression .. you should be happy if you make that ... Do u have full 3 inch exhaust and 1 7/8 long tubes as well ?

i do not have longtubes but i think this setup shows promise, the run where the pulley exploded the car made 645lbs of torque and like 630whp on the drag radials and 100 degree weather. The pulley busted at 4700rpm so i dont know what kind of hp it would have made but we were still in the process of tuning so there was a little more to be gotten. The finl numbers on the 2.75 cam out to 602whp and 617wtq. it was only hitting 17.5 lbs of boost on the 2.75 for some reason, maybe because of the heat. im going to try to get another 2.5 pulley and go at it again.

according to the e85 hp list, 3 others have as well. 650cobra made 703/716 stock engine and kleistang made 748/770 with a stroker and skaarew04svt made 719/655 with a 10:1 alumintator engine

Just dyno the car in February and call it a day. Like I said call RR I'm sure they will work with you on the 2.5 that came apart. For what it's worth I would say run a 2.9 upper only with timing and call it a day. Your stock pistons will thank you :) The heat from an over spun blower will kill whatever extra boost you may see from the smaller pulley.

My car made 708 whp with previous owner (bb97gt on here) with a 2.3l and a 3.0 pulley with 21 psi. BBK Longtubes

Tune on it now is 675whp with a 3.25 pulley at 19psi.

Both e85 tunes obviously.
