Im rebuilding & SP my engine soon and was wondering what kind of FWHP i should be at.

Rebuild and SP
S5 Rotors (high comp)
Full RB SP Exhaust
S4 upper intake
No AC, Efan, K&N Filter
Air Pump Operated 5&6 ports

10lb Flywheel
RB Heavy Duty Clutch

I am thinking, maybe around 200hp
I really dont want to go carb b/c of daily drivability issues being it my only car and all.

Thanks
Greg

 

You will have exactly 0 FWHP at 0 rpm. FWHP will go negative as speeds increase, and will depend on inflation pressure, tire properties, and condition of your brakes and bearings.

I would think that the afm will limit your hoursepower to something less than 200, so I would look as swaping in a later one of those as well.

 

200 sounds like a good estimate with that setup .. what kind of ECU though?

 

With a stock ECU I don't think there might not be too much gain maybe 20 hp more. I could be wrong though!

 

It would be a stock ECU for now, later a microtech maybe next summer.

I figure that the RB exhaust should give me about 15-20 hp if they are being anywhere near honest about their hp increase claims
The streetport another 10hp or so
And the S5 rotors would be good for at least 5hp then the other stuff like another 5 hp at least
Making at least 170 flywheel hp

 

150-160 seems realistic. ~130 at the wheels.

 

Really I was hoping for more, oh well I guess a microtech is in order.
