I am so surprised today!! I went down and ran the Iroc on the dyno machine today. A bunch of friends rented time so I joined in. My eyes almost popped outta my head! I knew I was a bit over stock but...so we ran it again and the same thing. I want to know what you guys (and gals) think. All the other cars were on the money and expectations so I'm thinking the machine is good. So here's the set up: '88 Iroc 5.7 TPI
-K&N's ducted to the grille openings
-Descreened MAF
-Coolant bypass @ the throttle plate
-Desmogged, no air pump or a.i.r. tubing
-Hooker Headers, Magnaflow freeflow cat, 80 series magnaflow muffler
-GMPP 1.6 rr's w/ the exhaust valves just a tick loose for better cooling
-adjustable fuel regulator set at 47 lb.
- 3:23 10 bolt posi
-all stock GM ignition components

296 hp---310 ft/lb torque !! check out the graphs! I was so happy I just had to light 'em up for a nice smoker!

 

It says BHP, which is power at the flywheel, and I guess they need to fix the date and time on their machine, unless you went back in time 17 years to dyno the car.

and why pull in OD (says 4th gear)

 

-they've programmed for the adjustment to flywheel hp. The pulls we're actually made in 3rd gear. So it's really about 255hp @ the rear wheels. I think that's pretty good for a stock mtr that's just breathing a lot better.
