I finally got the car to the track and it was probably the hottest day of the year so far. DA was around 2800'. For the first time running with the supercharger and taking the weather conditions into account, I am very happy. I hit the rev limiter in third gear which I feel hurt my mph some. 1.507 60' 10.23 @ 134.64. I know the car has 9s in it with alittle more practice and cooler weather.

Very nice... Im surprised that the 60lbs injectors supplied you with fuel to 850rwhp+ on a SC'd car. My car maxed out the 60lbs injectors at 4500RPM where it saw 700rwtq and 640rwhp only. Base FP was set at 70psi and it held around 78psi or so by 4500RPM seeing around 8-9psi.

John,
Maybe you have mentioned this in a previous post but I was wondering about your T56. Have you had the internals rebuilt to withstand that power and torque? I couldn't imagine a stock manual tranny being able to hold 864 rwhp

Just so all you smartass Glen Burnie people know, I don't tune my car on a dynojet. I tuned the car on the street so I feel that is even better than a "MUSTANG DYNO".

Really how does the car hook at WOT on the street? the more load on the car the harder the inj. need to work. While the car is spinning during your "tuning session" its not telling you ****.
Not that everyone needs to use a dyno (some guys tune at the track) but you posted some dyno numbers so I assumed you would have done some tuning while it was on it.
Jeff has a car at the shop with a F1 and a 402 and it ran out of fuel with the 60lbs inj. at like 4700 rpms.(Custom fuel system with 2 pumps)
Since your SO smart I wont comment anymore on your 10 second monster

Well just to give people an update on my car, I have had a few problems lately. First my twin disk Textralia clutch (Exo-skel) started slipping on me in 4th gear. Did alot of research and decided to try the Spec twin disk clutch. Put it in and seems real nice and went to a private track rental last Thursday (6/14) and on the first run of the night broke my output shaft. Going to upgrade to the Viper output and maybe have my gears mikronited. For those that suggest me to put an auto in it, just forget it it isn't going to happen.

INSANE combo.
Props for doing it all in your garage and then taunting it around that you did it yourself and that it IS possible for all of you who believe that only a "shop" can make a car like this.

I've heard numerous times that injectors should NOT go above 80%. 130% sounds dangerous, so personally, I would switch those out before going WOT again. Especially with all of the effort you put into it, I would hate to see you come on here all bummed.
Sweet ride though and I'm glad you are keeping it manual.
