About a year and a half ago I did a dyno on my car with stock intake/software, euro headers/larini cats, borla, ss res replacement pipe in 50 degree F weather on a Dynapack Chassis Dyno. Best results were 301hp and 265ft/lbs.

For today's dyno, I've added AFE intake and Shark software for euro headers and have since put the stock resonator back on (trying to quieten down the Borla a bit) and used a DynoJet dyno and a different operator. Temps were 88 degrees F with close to 90% humidity (at least it was two hours before the run) and my best run was 311hp and 257ft/lbs. Peak hp came at 7400 rpm and tq was above 225ft/lbs from 2500 rpm to 7200 rpm (above 250 between 4400-5400 rpm). So the tq curve isn't much of curve - pretty flat overall.

What does all this mean? At least I think can say that my car is making in excess of 300rwhp under different conditions - seems like a safe bet given two different dynos and a fairly warm conditions the second time around.

It would be fun to see the results with 100oct and a cool day....

I would say the dynopack is normally more accurate. Dynojet had inflate the numbers.

Also, the dyno should compensate for intake temps (assuming you can gather them).
