What length did you run and what rpm did that give a peak at?

@FT-86 SpeedFactory, wil you be sending Velox a header to test this with? From looking at your site I see that you sell one of the top end brands, it would be a good representation to show what the combination would look like.

lol if he responds to this I may bust out laughing. And he knows why. Eric... Maybe we should bum Brent's car this weekend... Hahahaha! (Inside joke)

If you extend a runner typically you increase peak at a point and then add a curve to the power band. Just like what happens with the crawford manifold spacers....

Based on the above, I would assume they didn't see much of a peak.

1.25" height and seeing peak load somewhere around 7500. But for the most part its flat all the way to 8k RPM. Not sure what this translates to hp/tq wise but it feels great up there.

This was a FI intake manifold build, though for some reason most people believe we were building it for NA power. The fact it is performing NA leaves us with a lot of hopes for both platforms.

No need as I'm sure we can work something out with locals or their shop cars.

One more picture:

Will there be two versions? One optimized for NA, and one for FI?

Two reasons, 1) This thread is posted in the engine forum not the fi forum, 2) alot of us are still holding on to a glimmer of hope.

Possibly through different bellhorn heights.

Hold onto that glimmer... especially if you feel comfortable revving the engine .

If you sell it for NA is there an specialy Ecutek Map in the bundle?

The only reason I want this manifold is for the 9k RPM redline NA motor I'm going to build...

wtf! you cant say shit like that and leave us hanging!

It's more of a wish list at the moment.. I have a 4 month old daughter too, so the car kind of got the back burner.. but I am building it in pieces. The plan is to get another engine and do head work. I live close to the guys at SCR performance and my wife is good friends with the owner. Check out this build if you haven't (LINK). They went with boosted setup. But with some head work, oversize valves, better valve springs, @NotEric6 's intake manifold and a full exhaust we should make some power up to 9k!! I would also do a 4.56 final drive and have some fun!!!
