Thread: What we all been waiting for!!!!! VE head flow figures!!!!

So actual numbers are 397.5 @.550" lift on IN and 287cfm@.550" on ex.


ENJOY!!!

This is all good and well. But what is the diffs if its translated in Wheel hp?

4whp more?

I would just like to know whats the relation between the flow data and actual hp on the wheels

What's the valve size on the last 2 charts? 2mm oversized? The valve size is partially missing at the top.

Nice.

Well valve size is larger than 2mm over. As for hp figures well we can theorize since no one has this setup yet as I know of. To put it in perspective Charles made 520whp on smaller valves and a head flowing around 280cfms.... This was at 15psi.

The reason why this setup was done was too make power but at a more efficient level. I rather have an engine making let's say 800whp at 25psi rather than 800whp at 32psi. The engine will have a better VE; less pumping losses.


Now peak flow numbers is not really a good indicator but more of how the flow progresses throughout the lift range. The sweet spot to look at is right around .300 lift; the head is well into the 300s on the intake and pass mid 200s on the ex. The percenatge of the ex flow is 80% of the intake which is a good indication how well the head flows holistically.

What a waste of money....JK. This is going to be a nasty set up is all I have to say. Just need to find the right cams for your motor.

Yeah cams, well we have an idea as you know. I will look into custom grinds after the tests.

Nice numbers.All we need now is for someone to come out with
some big VE-T cams for high hp setups.

As for cams we will try a a couple OEMs and a custom set. I do think one of the OEM sets will be respetcable.

Yeah I think playing with the 20V and N1s will be interesting. Also see what the custom ones do too with both are set ups. It will be fun.

The 20v I think are going to make the most for both of us but throwing the N1 ex cam in there will be interesting to see what happenes.

Matt

Sure will...I really want to see how the N1 ex does with the 20v IN, I think the N1 ex will be better for my setup.
