And the test with the modified itr? Always running?

Re: Header Test Repost
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. https://honda-tech.com/forums/images/smilies/emwink.gif https://honda-tech.com/forums/images/smilies/emwink.gif
Here's a couple more graphs that I got from VtecKidd from this test. HP vs AFR SMSP 4-1 http://is.rely.net/1-1142-18788-l-Ue...6H48m1xPRQ.jpg SMSP 4-2-1 http://is.rely.net/1-1142-42413-l-wc...oIeMa1IFaQ.jpg |

Re: Header Test Repost (VtecKiDD)

Re: Header Test Repost (VtecKiDD)
i guess the RMF narrow is hands down the best, midrange and top end.

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). http://is.rely.net/1-1142-31242-l-6e...2da7tHs8mQ.jpg |
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.. |
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 |
thanks again for all the hard work
|
Re: (machine4321)
questions about test engine: was a cat used? what size exhaust? how was it tuned? crome or vafc? thanks |
Re: (greeneyehatch)
Crome tuned, dynoed open header
|
Re: (VtecKiDD)
what was the baseline whp?stock itr?
|
Re: (greeneyehatch)
baseline for all intensive purposes was done with the DC header
|
Re: (VtecKiDD)
vteckidd i pm ya!!

Re: Header Test Repost (VtecKiDD)
i made good power with the Rmf Header muffled up and i wanna try it again open header see if gain or even a test pipe so please let me know you guys think will gain more power open header???? or with a test pipe and how long u think test pipe should be??
Modified by Palma4dr at 6:07 PM 2/26/2006 |
just wondering i am getting ready to buy a header and is there a difference in power between the rmf narrow and the rmf street header also is there a difference in cost????

Are you a retailer, and do you sell any of these headers? |
Re: Header Test Repost (George Knighton)
now im not a retailer. i do not sell any of the headers listed nor am i a AUTHORIZED DEALER for any header.
if someone needs an RMF header , ill put the order through, but ask Import Power House, i get no money off. why, is someone upset George? |
