5sfe stock hp Options

[JasonX]

hello guys,
just wondering when 5sfe supposingly says it's 135hp, is it really 135 hp? and what's the difference between hp and whp? i was wondering 'cause I heard the gains from cams is 20-30 hp. so, if I had colt cams and injen sri, could i claim 160 hp. just don't wanna say I have around 160 hp and bs myself .

thanks

on this dyno what's the line that initially starts low, and what's the higher one?

The first dyno is not what a stock 5SFE dyno looks like. That's vastly improved over stock by about 10-20whp depending on the motor's condition, and the torque curve is significantly better. Typical 5SFE's will run out of breath around 4500 rpms and the torque dips significantly. The top dyno doesn't lose much torque until around 5300-5400 rpms. That is a significant difference in terms of accelerating the car. IMO, whoever that dyno belongs to, can still squeeze extra power with some good cam tuning.

As far as which is which, the flatter line that starts flat is usually the torque (applies to most engines) and the line that climbs as the rpms increase is horsepower.
