i searched for awhile and found nothing (suprising with the new search isnt it?)

so im sorry if this has been done although i dont think it has.

im looking for anyones graphs who have dyno'd with bisi's header on a b series. im interested in seeing the power curve. and any increases over other designs. thanks

bump...

well i have a b16a SIR2 in a del sol. it won't be an exact dyno since i lost my stock dyno sheet and it'll be a full exhaust/header swap. but in a few weeks when it gets all done(i broke some bolts) i'll take it to a dyno and put it up.

but i guess for stock comparison just back to back with any old stock b16a.

It is surprising.. search works perfect for me. You gotta know how to use it/configure and you should be good.

not for me. its a pain in the ***. and never finds what im looking for. so i good what i want and put honda tech at the end and it takes me somewhere in here that actually has what i want.
also interested in the bisimoto header and how it would perform against a profab or some high end headers

teg_racer

btw.. if your interested in buying the bisimoto.. you should sell me yours haha

I think the OP wants to see same-day dyno comparisons which show A/F ratios and perhaps even screen shots of the timing maps that were used during the tests. Good luck on finding results. You may have to do what I did when wanting to check out the fake RMF narrow header and just buy one for yourself to test.

This is awesome.

If there are people out there looking for numbers , here you go.

However, I wish they were 3rd party independent dyno graphs. I will post my own b4 and after once I buy my header.

did you buy one?

Also from the link of Nerologic thread, that bisi header is crazy.. I had no idea you had to cut the front bar of the car.

Red_Army

mine fit without having to cut it. but his is clearly much bigger then mine.

I just dynoed a 86mm X 87.5mm (GSR Cranked) B series 12.5/1 comp that I built, that made 234.4whp and 160wtq



The header pictured was a prototype and broke twice. It was returned to Bisi and was upgraded for slightly more money to a stainless steel unit. The fitment was different than the prototype for some reason and the core support required modification to fit. I will take another picture and repost later.

Im not sure if it is the header or just the fact that I am one bad *** engine builder...

Everytime I look at those dyno charts of Bisi headers SLAYING everything else by a wide margin, I seriously want to buy one and compare it to the SMSP header on my car. It's not that I believe all the hype and it's not that I think Bisi's headers are bad, I just have a hard time believing they are THAT much better than everything they get dyno'd against on his site. I may seriously do this this as my next little test project...

234/160 is no joke, what cams are you running?

Just a sugestion here... you might try actually reading all of the posts in a given thread, so that maybe you would have seen that information was already posted, sir.

I am running a somewhat small set of Web Cams. I would like to Try some Skunk2 pro2's or bigger, as I am sure I would get even more out of it.

SR20S13

well i just got mine in, when i get everything done i might try to do a few different test at IMW in Penn. if he will let me, and well i could get enough headers together

thank you 2point6 ...

please provide updated picture. I'd love to see it cause I have a EF too... lol

Im curious what your power band looks like....post the dyno chart please

airmaxbri

How high are you revving to get 234/160? that's mad torque from a 87mm.

Do you think the bisi header helped you get that number?

Did you stick with the bisi header? Have you tried other headers with this setup?

sry for all the Questions, I'm serioiously considering buying a bisi.

peace

Ok.. i love bishi, i really do.. he's a great guy and i'm pretty sick and tired of everyone getting linked to his site.. this is a 1st person dyno..

we need 3rd party comparsions.. we need bishi's header to be test vs real ****.. not some lame *** ebay headers..

SMSP
RMF
SSR's
DTRS
profabs

we need real test on a real motor.. everyone keeps saying how bad *** bishi headers are.. and frankly the dynos of motors with bishi headers are few and wide between.. i see more dyno plots with smsp/rmf knock offs or ssr or some type of custom header rather then bishi's and his sale people claim EVERYONE buys his headers.. i was even thinking about it, but i want to justify 900 dollars.. just like i told BMCRace about their manifold.. i want dyno plots.. i've seen one... period.
