how much rwhp is a street port s4 expected put out?

 

on a n/a?

 

~150-160rwhp

 

found out somthing interesting today. I'm not sure if this is a major problem but could explain somthing. The Intake manilfold has leak near the engine. Don't think its big but is leak. Could this affect the power the bad or is somthing else. Oh the compression fine i had the mechnic do it the right way.

 

The leek would allow unmetered air into the engine, which would cause it to run lean and lose power.

 

boo yakka!!!!

 

Hey How can i Inpect the ports..and see if they are opening and closing like they should..I hear alot of talk about them..but not sure if this is an External peice i can move by hand?

 

I've seen street ported N/A's put out the same numbers with the same mods. Street port's on N/A's don't do **** unless you beef up the air and fuel. Otherwise the same amount of air/fuel will still be flowing into the motor. Not making any difference really.
