The only thing you have that will free up HP are the U/D pulleys.About 5 HP at the rear wheels.

Perhaps 235 at the wheels, give or take from the intake and pulleys. With the Diablo, it'll vary. Without more breathing mods (intake side or exhaust side mods) you might only see 5rwHP and a like amount of torque.

The d/s, gears & shifter will give you nothing in terms of power

What HP:

-BHP
-PS
-Metric
-Imperial
-DIN
-SAE Net/Gross
-Flywheel/crank
-Rear Wheel
-Corrected?

Stock factory engine is rated on an engine dyno @ 260BHP SAE Net a rolling road dyno should give you numbers anywhere between 220-240rwhp depending on the EXACT conditions on the day and what scale of Horse Power is used.

Current mods could have increased power by 10-15bhp crank which should equal slightly less gain at the wheels.

Driveshafts and gears will not increase engine power. In theory they (esp driveshafts) should reduce the loss from the transmission but in reality not by much on a stockish setup.

225RWHP is my guess right now, and figure another 5 from the diablo.

does anyone know about how much more hp would've been added to my car?.. the last dyno was done before i got the accufab 75mm tb & plenum and the mac straight shot and the steeda underdrive crank pulley.. it dynoed at 247 rwhp.. about how much would all of that add to the rear wheels?.. and after those gains, about how much would you say i would be getting at the crank?

^ should be right at 260RWHP...starter you should be at 235 right now, the gears actually cost hp on the dyno (not in real world by any measurable amount) so maybe not even that, the diablo should give about 6 peak, but torque under the curve should be near 20.
