Thanks to VtecKidd and Johnzm again for taking the time to do this test. I'm sure they learned a bunch about the politics of header testing on H-T. Click the image to open in full size. Click the image to open in full size.

Here's a couple more graphs that I got from VtecKidd from this test.

They just show the AFR versus HP for each of my headers. I think it's clear that there was a lot of room for improvement, however the amount of tuning time available was limited.

BTW, my 4-1 doesn't really like be run open, the dump tube must be tuned for length. Here's a graph of the same 4-1 header on my B20VTEC for Honda Challenge H1. One is with a 60mm/2-1/2" exhaust (red line-no dip present) and the other is run with an open header (blue line-same dip as in the above test).

Default Re: Header Test Repost (SMSP)

yeah we had 8 headers to test, and time was limited, each header could have seen lots more tuning time but the day was 10hours long already.

this was just a comparison, we did maybe 8-10 pulls on each header, and got the a/f as close to 13.5:1 as possible. there were spikes here an there. but i was satisfied with the time we had

This is just one header test on one motor i can easily see all the name and numbers flipped up side down on another application. A wise person would use this test as a reference tool and make a knowledgeable decision on what will fit his need...

just something to think about..

Default Re: Header Test Repost (Six Sigma Racing)

this is true, in this test it won, however, i have seen other test where other names on that list have been better off.

TEST IS A GUIDLINE, not a absolution.


BTW id like to see what the street sweeper header would do

if someone needs an RMF header , ill put the order through, but ask Import Power House, i get no money off.
