Ive been getting TONS of PMs about the header test i did. Tunerzines article is down, so im just gonan repost all the info, so people can read it instead of sifting through 24 pages of the original thread.
TEST ENGINE:
JDM B18C Integra Type-R STOCK

PLACING:
1st RMF NARROW 4-1 185.61whp/128.49TQ
2nd SMSP Prototype 4-1 184.70whp/128.98TQ
3rd SMSP 4-2-1 182.38whp/123.82TQ
4th ANR w/Merge 181.05whp/125.79TQ
5th DTR B-Unit 180.82whp/125.46TQ
6th Hytech Production 180.63whp/124.19TQ
7th DC JDM 4-1 174.24whp/124.04TQ

this should let you know what header is what.

DC SPORTS 2.5in vs HYTECH production header (same as RAGE)


Hytech vs SMSP 4-2-1 (sparks style)


SMSP 4-2-1 vs DTR B-UNIT header (similar to HYTECH and RAGE)


SMSP 4-2-1 vs PROTOTYPE SMSP 4-1


SMSP 4-1 Prototype vs ANR with Merge collector


SMSP 4-1 Prototype vs RMF Narrow 4-1


Now here are the individual headers VS the RMF
RMF narrow vs Hytech/RAGE


RMF narrow vs SMSP 4-2-1


ANR HEADER w/MERGE vs HYTECH/RAGE



PLACING:
1st RMF NARROW 4-1 185.61whp/128.49TQ
2nd SMSP Prototype 4-1 184.70whp/128.98TQ
3rd SMSP 4-2-1 182.38whp/123.82TQ
4th ANR w/Merge 181.05whp/125.79TQ
5th DTR B-Unit 180.82whp/125.46TQ
6th Hytech Production 180.63whp/124.19TQ
7th DC JDM 4-1 174.24whp/124.04TQ

Nice test. let me know if you want me to send you one of mine so you can do a comparison. Highend autosports

And the test with the modified itr? Always running?

SMSP

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.

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

HP vs AFR

glad i went with the rmf

MichaelPal

very nice guys...thanks for the effort

OMG WTF

i guess the RMF narrow is hands down the best, midrange and top end.

I can't wait to see how my RMF performs..

Dave could you explain me the meaning of the graphs you posted about the afr?

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).

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..

0VtecKiDD

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

machine4321

thanks again for all the hard work

greeneyehatch

questions about test engine:
was a cat used?
what size exhaust?
how was it tuned? crome or vafc?
thanks

0VtecKiDD

Crome tuned, dynoed open header

greeneyehatch

what was the baseline whp?stock itr?

0VtecKiDD

baseline for all intensive purposes was done with the DC header

greeneyehatch

vteckidd i pm ya!!

Palma4dr

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??

boostd ls

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?

0VtecKiDD

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?
