We.....
OK.. but has anyone found the limitation of the valves? i.e do they bottle neck at 300? or what? Or are they good for 350?
xjay1337:
Yes me and my chin are doing it.
No-one knows. no-one has publically pushed the engine as far as we are going to.
Headflow is an issue we know this.
so while porting it makes sense to fit oversized valves.

We are doing a test this coming Saturday.
Currently my lambda is around 1.1
we are running a 0.9 lambda tune with no egt protection (dummy egt sensor) to see how much extra power it produces (if any).
People in europe claim 280+ from stock fuel pump on gtb2260 when myself as well as bobby and other tuners (including darkside) cannot do that on stock pump safely.
as we are on cp3 fuel pump already have more fuel than these other tuners ...we find no more airflow available.....
so we must test.
we will see. :-)
After the test i am reverting back to current map and functional egt sensor as i drive too fast to not have the sensible software on.
