Hello.. I have a built 2.3 evo 7 with gt37 turbo and full bolt ons but i still have the stock intake manifold and throttle body..what is the limit of the intake manifold if i bought a full blown 70mm throttle body?

 

Nope.

 

Stock TB has gone to 830whp but that is about where the 60-62mm hits the limit. Rally car physics but at a higher level. Going to a 75mm was worth 70+ whp the last time I tested it out. I dont use stock intake manifolds at that level though.

 

So i need both the manifold and the throttle body to gain more power
