I was cruising around d-series.org and came across a bisi header dyno. Just thought i'd post this for the d-series guys out there.

This is taken straight from the site:



FYI the test mule is my '93 Civic CX with a stock D16Z6 engine with 200,000 km on it along with a Comptech Icebox and a modified (or moosified as we like to call it in HADA) Z6 exhaust manifold where the downpipe was enlarged such that the inner diameter is 2.25'', a full 3/4'' larger than the stock downpipe (see the bottom of our header comparo page for more details). We know from experience that this modification improves midrange considerably and helps peak horsepower by as much as 3-4whp on some Honda engines (ie. B16a). The 'Bisimoto header was then immediately installed (thanks Moose! Hope that burn it getting better...) and we produced the red horsepower and torque curves, showing an 8whp gain over our modified Z6 manifold. For a race header to produce such significant gains over a modified Z6 header on a completely stock high mileage and thoroughly beat Z6 engine is very impressive IMO and I look forward to testing the header again once I've installed my high compression Z6 block with ported Y8 head and a custom Exospeed camshaft. Stay tuned! (no pun intended...) I think this header is going to post some killer numbers on a race-built engine that can take full advantage of the design and tubing diameter.

:rockon to 'Bisi! :rockon to Wil at Exospeed for shipping this beauty to me! And :rockon to Fireball Coatings up here in Ontario for doing a really nice job ceramic coating it for me! Oh, here's a sexy picture of the header relaxing on my leather sofa before being put to the test...




I think this header is great. It is ( imo ) well worth the money. Also from the site it's said this header cannot be used with a/c, not sure on p/s but definitely no a/c. It is said bisi is working on a header for a/c compatibility.

Comments ?

 

nice numbers.....the header looks sick but A/C removal would be crazy in Miami

 

yeah man that thing is crazy...nice numbers and keep us informed about that build up...

 

Well, i will if i can lol. I said at the top it's from a diff board. I just transferred it in case you guys might have been interested. I too could not afford to be without a/c. Lets hope bisi comes through with the a/c compatible header :thumbup

 

If you wanna go fast you'll do whatever it takes. hehe
i used to sweat my *** off just to get the CRX as fast as I can get it to be.

on the Bisi header dyno.

haha i hardly ever drive with the ac on unless i'm defrosting the window. Gotta squeeze every last drop of power outa the car lol

 

Really nice header.

 

Damn!! Most headers I see give only good top or good mid range power. Glad to know this thing produces top mid and bottom power.

 

sweeeeet gains in HP....
crazy looking header....
thumbs up

 

i wanna get one !! but it most clear the p/s !!.. anyone know about that !? if it do ?

Ive learned if you wanna go fast buy a car that comes from the factory fast or buy a bike

Yeah..nobody can outrun my stock fast Honda (VFR750F)

 

I know what header I'm getting.

Thanks for the info.

 

thats awesome i can't wait to dyno mine ,it looks great coated

 

It does look beautiful with the coating :D. This will be the header i will get if bisi manages to make one that will allow a/c.
