The solid line is the Gen 6 baseline from before.

The other 2 lines are back to back dyno's right after the other with the newer full merge header that i posted.

The car sounds different now, especially at idle and low RPMs... sounds really cool... I actually let Dan drive on it today, so I hope he has some impressions....

^^for this dyno whats the mod list?

Here is the car
The difference in the graphs is one is SAE the other is STD

If anything this should show you how different our Acutal numbers are in the NW vs SAE numbers.

Run 27 below is right after run 26 above so you can see what SAE gen 6 looks like on our dyno in run 26 above vs ASP header
Those are sick gains from just a header. N1 cams don't even gain that much as a single mod

Run#27 is the HS Gen 6 baseline. Run#33 is Charles' "budget" header. No, I don't have that backwards - the budget header made almost 9whp peak more, and at one point in the midrange made 15whp more. This was a slapped-together prototype!

My setup:
N1 cams, +5/-5, switching at 5000 and 5800
JWT intake on a PR short ram
Nismo AFPR
3" Magnaflow cat, 3" exhaust
Redline Shockproof Heavy
Calum RT with stock VE maps

DE maf
calum ecu with stock VE program

Gen 6 header is the lower one

my ASP 4-2-1 header with full merge is the higher one

very simple build

Yeah, Page 1.... all (or atleast most of) the info you need is there.

Man Charles this is making me seriously consider throwing down the extra cash for the merge collectors.

How much longer would I have to let you know? (If it's not already too late)

Charles would you be able to do a full exhaust setup? "Header to Muffler" thanks.
