A stock lowport outflows a stock VE according to the numbers Charles has supplied.

Edit: This is based on different data sets. My later post clears up the confusion.

^Dude are we still talking about heads? If so, then why would be go through all the trouble of putting a VE head on a DE bottom end to gain head flow? Post your findings. I don't believe that.

Low-port DE:A Low port head flows about 240cfm IN @ .500" while a high port is 185-195 @ .500" according to Charles

According to BigTom a lowport DE with intake will flow 261 @.500"

VE Head:
Stock VE Cylinder head, flow @ .500" valve lift, with Stock N1 intake setup 226cfm according to Charles

According to BigTom a VE with intake at .500" flows around 270CFM.


Really, almost none of you are squeezing the potential out of your engines. There is a reason why Ben and I make a lot more power than most of you guys with the same mods.

Dan, your links to direct pages don't work for 95% of users because you've changed how many posts you display per page, and the forum software can't reconcile the link to the proper page.

The post you link to from Charles doesn't have VE head numbers. It has VE head + N1 intake manifold numbers.

I was about to say that. I was like where is waldo?

I might be off with those numbers but it's what I remember.

Ben is very wrong with the data about ported low-port heads. But end the end a VE will outflow a lowport.

Don't bother with a highport.

You sure I was wrong?


And to add more info, daxx got about 330 cfm @ .500" from a worked VE head.

OFF TOPIC:

^Dude, all you have to do is get a bigger turbo if you want more power (You know this though). Look at Asthon's SE-R on the highport head. I also believe Fred Casey had a highport as well making around 550-600WHP. I'll be rocking a highport since I already have one with a P&P/3 angle valve job with a big snail making power.

Anyway, THOR I think you have enough info to get to 245+. Sorry for the off topic, but the title don't say N/A or Turbo.

Yeah at .550" on 2mm oversized valves.
