Thread: Headers Dyno Comparison Thread

does the x-force headers need port matching for ve?

Has anyone dynoed Charles 4-1 header that Gspec/Greg sells?

Happynole has a freak header 4-1 on his SE-R...His nx has the ASP budget header.

^It's a 4-1, but it's different from the slip kind on the GSpec site. It's more like this one.

^^^you are right,my bad...It is very similar isnt it? .I got a ride around the small track here in FL while Joe was here.That thing is a beast!

Yeah thats the one I have. What was his cam settings if you remember?

Not even close to the same. First of, my 4-1 has seperate flanges with a much better finish (smoother) at every weld. It has stepped primaries. It is a slip fit with springs on a Burns collector. It also has a reverse megaphone. The secondary is the same though.





It's at least 3 or 4 steps up the ladder from the header you guys just posted.

No Jay YOU were right.....................and it is a beast!

We haven't even had the chance to fully tune it yet. I've still got my cam gears at 0,0. Tuning will be coming soon now that my Realtime finally got here.

just needs the bolt holes slotted slightly

^I guess you were right Jay. I road in Joe's car as well. It is a beast of a VE.
