Highest HP on stock inlet manifold?

[Julian Iversen]

Hello. I was just wondering if somebody knows what the highest possible HP are on a stock inlet manifold?

Just like to know if i can keep the stock manifold with cruise controle

Fairly certain 500 has been done but it's not the best design...

I know but i just like to keep the cruise controle and AC

What is the problem with the stock design?

It's not going to limit you in terms of HP just in terms of throttle response and cylinder balance.
What I mean is there is no reason you could not make 1200 HP with it, given
enough boost.
People have made 650+ with it many times, but it does not have the cylinder
filling balance of more exotic designs that people use when tuning to the edge, but like I say you could make 1200hp with it if you wanted to, just that 1 cylinder might be making 230 HP and another making 250, not ideal, as you would ideally have them all making an even 240 HP at 1200hp tune with the right manifold.

Okay, Im thinking on a GT3076R mayby GTX and about 500 hp or more if its possible. So that should be no problem

I believe the Wagner manifold fits with the AC rad in place? And then you just need to make a bracket for the cruise control diaphragm

100% true , it did work on my S2
