How Much Hp Can I Make With Stock Neo Intake Manifold?

[TP_]

Hi there.

I'm finished with my new bottom end on my car, next week it's mapping time.

Last year I got 474rwhp (353rwkw) on 1.5 bars of boost from my GTX3076R with a .82 exhaust housing, I don't want to swap for another intake as it gets a lot harder to get the car through the yearly inspection.

Has someone tried to take the stock manifold to the limits? where will it stop giving more horses?

HP-limits and, or boost-limits?

I would be happy to push at least 530rwhp with the stock manifold now when I got a fully built bottom.

Most important specs:
Poncams 260/9.15 in/ex.
GTX3076R .82 exhaust housing.
Link G4 ECU.
Ron 98.

Get it on some e85 and squeeze some more boost in Mattias. I hear ethanol is easy to come by over in Sweden...

I just made 596rwhp on stock intake manifold. It can pump more then that.

There are probably no limits within the power levels that can be achieved without race team budgets.

On 98 octane?

If you are worried you could always machine and polish the intake?

500rwkw is achievable but pushing it

+1 pump 98 is more of a restriction than the intake manifold is.

Plus I do not believe changing the intake manifold will yield a worthwhile result on a GTX3076R. I think OP is doing quite well already.
