hp calculations / my car's weight
hey guys. I just g-teched for my rwhp again, but this time after I set up my ram air. (IT SUCKS THOUGH). The foglights are still there, and it is just a crummy little four inch diameter rigid plastic tube that I made point up toward the air filters and flattened the other side to fit in the fog light hole. Previously, I got about 278 rwhp, but it tells to input the car's weight and with my zz4 motor (aluminum heads remember) and no ac, with me in it, I put in 3600 lbs. This time, I put 3730 because my fiance was in the car also and I got 286 rwhp! I have 2.73 gears and was wondering how much hp loss I can be expecting from the flywheel to the ground. I have heard anywhere from 20% to 30%, so I figured 25%. Is this correct? If so, then I should have about 357 hp which sounds about right, I am thinking. Unless my car weight is off or???? I dunno. Any help is greatly appreciated. I took a special notice to see how much I am peeling out, and it is WAAAAAAAAYAYYYY too much, hence my 13.7 @ 107 (g-tech) time. When I get drag radials, I'm gonna try again. My mods are below
ZZ4 crate motor
hi flow cat
edelbrock headers
flowmaster
custom chip
700r4 w/1800(?) stall, billet servo & transgo shift kit
24# fuel injectors
crappy ram air setup / airboxes gutted
k&N airfilters
tb airfoil
tb coolant bypass
all I can think of for now

hp loss through the drivetrain is typically 12-15% for a manual and 15-20% for an automatic. You need to weigh your car for any of this to be accurate.
