I'm happy though, 150 HP is not bad at all. Next mod is a tune


well hers teh deal , directions were to take teh total weight of teh car with all passengers

teh fully loaded weight is teh weight on teh door

his total weight was 4300lbs (all 5 passengers) so we subtract 180lbs for every passenger that is not in the car,

no pasengers in teh car is 3400lbs(curb weight)

so we add 160(billy) and 220 (my fat butt) making teh total weight of us and car is 3780lbs

then we do our runs , our runs were off by maybe 5 hp b/c i ddint realize that the car was a 5 passenger vehicle as to where mine and my friends are 4 passenger vehicles, so there was an extr 180lbs

to prove this is teh right method, we ran my buddies redline and we got about 200whp , those cars dyno between 195 and 205

sorry for being so long , i just wanted to explain my point

as for billys car being 3400lbs curb weight , well he does have teh fully loaded car , leather/powerseats are heavy, power windows, door locks, not sure if teh ATX is heavier than teh MTX but it all ads up

anyways 170hp car making 150whp is a 12% loss which is expected drivetrain loss through an auto ,
theres and evin bigger loss in RWD cars

thanks
