A buddy of mine just dyno'd his car at Powertrain Dynamics in California. The car is '93 Cobra with the new HP Performance street kit, out of the box Edelbrock Performer heads, Cobra intake (lower matched to Edelbrock runners) and a B-303 cam. The short block is stock with the exception of ARP bolts, stock displacement, crank, rods, etc.
On a run with ~20psi of boost, they had to let off at 4500rpms as the boost was climbing a little too high. The car still put down
The torque had peaked at 4100rpms but the horsepower was still climbing!! These are actual numbers at sea level, no correction factoring.
They turned the boost down to a more street-friendly level and it peaked at 15psi but was bleeding down to 13psi (need a different boost controller) and the car made
Again, this is on the stock bottom end (with ARPs), the car has stock electronics with a C&L MAF, 42lb injectors and a 1:1 regulator. The turbo is the stock 60mm that comes base with their kit
. Tranny is a World Class T-5 with a SPEC Stage III clutch, tires are 28x10.5 ET Drags with 3.73 gears. The power curves are as flat as Kansas too, hehe.
Richard Holdener drove it down the street and after a 1st, 2nd, and 3rd gear burn he decided to take it easy for fear of his whitie tighties, lol.
Just some info in case anyone was curious on that HP Performance kit that has been in MM&FF lately. I gotta get me one of these babies.
