My brother's 95 Formula, which is bought new and only has 5000 miles on it, still has an internally stock engine. He put an ATI ProCharger P-1SC on it, and a complete Hooker header/exhaust system. The 4L60E with a 3500 Yank converter broke on the 1st pass down the track. He replaced the tranny with a Rossler turbo 400, and used a Neal Chance 4000 stall converter. A Moser 12 bolt with 4:30 gears was installed, and the suspension was fully done. BMR K Member, BMR upper/lower a arms, Spohn torque arm, Spohn lower control arms, etc. The car is only making 367 rwhp on my Mustang Chassis Dyno, yet it runs consistant 11.32 at 118 mph runs. We weighed his car the other day and it weighed 3508 lbs. This Winter my brother is going to remove the air conditioning, and install a manual steering rack, and possibly the lighter brakes and wheels. The goal is to get it into the 10's for now with the stock engine. This car can be seen in the project car section of my website. Bob

 

Not too bad..What did it break?
Thats crazy to find a car that year, with that many miles on it..

 

How loaded is the Dyno? Seems it may be producing a little more HP than that! What 60fts did he cut? Nice times by the way!

 

It broke the tranny internals. My brother bought it new, and just never used it. He always said it was too slow for him to want to drive it. It's kind of ironic in that now that he's almost into the 10's and the car is much faster, he pretty much only uses it a 1/4 mile at a time... Bob

 

Mustang 1750 chassis dyno, the 4000 stall always will give a lower rwhp number. His 60ft times have been in the 1.52 range. Thanks! Bob

 

Yeah I know about stalls hiding HP, kinda cool in an ironic way!
