just so you know... you cant just add hp numbers together... many mods work together and will only benefit so much, dont expect much over stock with all those mods.... this is again why i decided not to stay n/a... its just to expensive... for 2k im going to have a pretty damn fast car, n/a block but turbod... project starts as soon as i pick up the core i bought at the end of jan and will more than likely be finished in june.. read up on turboing a n/a by arron cake or sonic rat... sonic rat ran 8.2 or something in the 1/8 mile and trapped 95mph so you can only imagine what his 1/4 time would be

A 265 bhp bridgeported 4 port engine, as measured via an engine brake dyno, put down 224 hp when mated to a 2000-mile rebuilt TII transmission with synthetic tranny fluid and a stock TII clutch-pack differential. (note: not my car)
Based on this first hand knowledge, I estimate normal power losses through the drivetrain to be 15-17%.
Stock PP would affect rear wheel horsepower measurement or an engine dyno, but it would not affect BHP.
Also, given a 12 lb drop in rotating mass at the flywheel/clutch assembly (about the max you can go with on anything but a multi-disk clutch set-up), a 2400 lb car, by calculation, would gain 9-10 engine hp, or approximately 7.5-8 measured hp to the tires. BHP would not change.

Ok, cool. I was just making sure he understood those facts also.
I'm a boost creep...
