Buddy of mine posted this about Bisi on his Wiki page. Look at 2011, the only post :)

2011 places last in a header test preformed Jason "JayWest" Forbes. The other two headers were a real RMF (Randy Monroe) and a Logic "Tri-Y" headers. The test was preformed at P2R performance in Miramar, FL. http://vimeo.com/30353942

oh look, at the bottom of the article, there's a place for you to rank the article from 1-5 stars.
ONE STARRED
AND REPORTED
OK

Was the Bisi header they used for the test cracked?
LOL!

Born of Nigerian father with doctorate in International Marketing...
FUCK YOU,
and your god damned spam emails you cracking ass header frosted hair homo

LULZ. Not the first comparison where Bisi's junk places last or in the rear of the pack.
It seems like the only product with his name attached to it that has actually been making good power is the 3.6 SOHC turbo cam.
-
Bisi im not the smartest guy in the world, but can you tell me why your header place last? http://vimeo.com/30353942

Eventually everyone gets lucky. AFAIK, the cam wasn't exactly all in-house specs tho.

Oh, I am sure it wasn't.

If Bisi actually did testing he would see all those odd ball angles on exhaust manifolds never applies to the real world power wise. On the old man's h2b crx we tried making similar designs and came up with alot of torque below vtec,worthless imo and huge top end failure. Not surprised the classic tri-y designs owned his stuff.
-
Zoomie style runners with a collector ftw
-
I have always heard good things about the tri-y
-
The guy is always trying to over sell with overly complicated language. Glad to see a basic old school design that any person with common sense can see will perform.
-
Bisi nut swingers will keep him in business though,that be the cold hard truths even if his products are proven to make less power for twice the funds
-
Bisimoto, proven to make more power all the time 5% of the time.

Bisimoto, proven to make more power all the time 5% of the time, but only when not compared to the stuff that would make more power that they conveniently forgot to test against.
Fixed.
There are a couple scene groups on FB where people have figured out his stuff sucks. The market is coming around.

He has one of the few dyno's left in southern california still in business so we will be seeing him for many years to come. Im still very torn thinking that his all motor cars always were on the bottle since no one has come close to producing the power #'s he has with his accord motors running literally a copy of his setup.

odd resemblance

I should start dropping links to his stuff failing on the accord forums, all the F22 guys have huge boners for bisi. The only nutswingers more into him than honda tech are the accord people. Its fucking annoying.
-
the problem isnt that we all think its a 30hp difference. the problem is that he and his nutswingers act like all of his shit makes 30hp more, when in fact it made less.
-
From a all motor honda stand point that is fair amount of power. Also like I said the bisi header peaked at the lowest rpm which is what I experienced in a real world environment. It is not just about peak power with all motor cars but the ability to carry that power as most h2b cars with cams,port work,real intake will shift at around 9-9500 rpm's at the track even with b series gearing and a tiiite final drive.
I have been around alot of these setups and tuned a couple 280+whp ones and the funky angle headers never worked on anything I tuned.
Conclusion its by far the weakest header design. Peaks the lowest makes the leatstpower and will not carry power outside of peak as needed for all motor drag cars.

agree,
As the number of bends increase the restriction increases unless some other factor is introduced like stepped tube sizes. There is a reason why zoomies came about. Also it is clear he has no clue what happens after the collector given he chooses to place a bend directly after it, pretty good indicator he is a dumbass.
-
Any info on the motor that was used????
What intake setup was used?
-
Its a stock bottom end h22, pro 1 cams. Ported p13 IM with 4 to 3.5 intake pipe. Its in a gutted to hell eg that runs 11.5@ 115-116
-
na mike is a moron who has never been on a dyno
-
It makes peak power at the lowest rpm and as stated I promise that car shifts at 9500 rpm's and never even makes back to the power range where that bisi header makes a little more.
Trust me on this mike I have done alot of these h2b setups and Ill promise with the other brands the car will trap atleast 2-3 mph in the quarter. Been there done that with back to back header tests at the track.
Those funky angle shit dont work yo.
-
The lower powerband shift is a function of the primary length, which is why Bisi made a "bundle of snakes" so he could fit a longer primary length with a decent collector length and still fit into factory location. Due to all the stupid bends he has to use a larger diameter piping to overcome the loss of flow from all the twists and turns.
His headers were originally designed for use with ITB setups so the "noids" would come into play as the TQ was falling off from the primary length tuning. Thus making a smoother powerband instead of the typical ITB powerband. Also higher compression was a factor.
To take a "race design" and try to mass market it to work on a stock motor with cams and ported intake, ain't gonna happen.
-
Chris i am not arguing the facts with you. I used to be an all motor guy and know how important 2hp is and how important it is to make power as high as you can rev.
I just don't understand why they would go through all the trouble to do this test and not let off the gas at the same rpm.
Are you thinking were the power dropped off BADLY????
Who is to say that isn't weak valve springs. The run order of the headers, say Bisi first, might have lead to the others dropping off sooner. Notice the fall off in power happens sooner on each test, valve springs are toast!
Also, was the engine retuned for each header? If not this test has no merit. It could have been tuned for the best header and then the others slapped on for testing.
Valve float, D15B7, OEM springs with 200k miles, Crane 251-0016 cam......

And before you wankers get your panties in a bunch, I'm trying to be neutral here. Yes I've chatted with Bisi in person about these ideas over 5 years ago, even about QC and getting too big to where QC suffers, which leads to Customer Service getting overwhelmed and "it all falls down".....

Did anyone notice their massive Columbus day sale? lol A entire 3% off ALL orders. lmfao. Fuck bisi, fuck his pos headers.

Just some more info to chew on.

LOL locked thread because it took a non H-T turn. :noel:
-
lets all be real here, it was only 2hp less than 1st place.
I can't stand the guy either, but you guys are all acting like the other headers made a lot more power than his.
Let's be real here, it only made 2 whp less while costing $1100 while prone to cracking while of obvious chinese origin.
There are clone headers that make more and don't crack, sorry.
-
Bone,
Each header was tuned, so it wasn't a just throw it on and see whats up kinda deal. Kenny, the guy who tuned them is a good friend but also a competitor of mine that is a very smart guy. He didn't do this test to bash any product. He's done a bunch of tests with all kinds of parts, Intake manifolds, intakes, etc etc. We spoke about this for some time last night, and you can clearly tell the Bisi header makes less up top just from the fuel map. Theres nothing wrong with the valve springs, the power went right back up when the other header was put back on.
I don't know bisi, and do have a level of respect for him, but all of his products ive personally seen haven't worked up to the marketing and hype around them, esp when you consider the price difference between them. I feel sorry for the poor smucks that buy his BS. There should be a difference between an $1100 header and one made by a 14yr girl in a sweat shop.

Uh, dunno how I missed this, but I was vicariously introduced to the guy that made the v1 Bisi header. And his name's not Bisi.

I have always heard good things about the tri-y
Doug Thorley was the man.

thats it? Pretty Simple. Makes sense why they werent revving that high now.
-
The cdm tri-y copies run around 300 bucks so yeah
-
For a 1000 dollars shit better be made of titanium and come with gold gaskets.

Tom, thanks for the clarification.

Hedi, hummer :)

ew. pass.

You mean backdooring from the china factory all Bisi's headers come from, like BLOX does Skunk?

On my NA D (11:5:1ish , stage 2 cam ect . ) the bisi header made 5whp peak than the ebay special that was on it before. Everywhere else the ebay header had 2-5whp on the bisi. It fit like shit, it surface rusted like a mofo and they are way over priced.
-
the more scientifical the header looks, the more power it will make.

you paid 1000 bucks for a d series header O0. side note a dc header with modified collector works like a charm on d's.
-
the more EXPENSIVE the header, the more power it will make.
fixed. For $1000 that header should suck my cock, tuck me in, then make breakfast and go away before I wake up.
IMO the cost for that last 2% more HP is far more than it's worth. And I don't just mean money.
-
Guys buying a custom built header in n/a is worth the money if you even remotely give a shit about your build. It is seriously identical in relation to the price people spend on turbo manifolds / set ups. So......
Plus just be happy you don't have a v8, $2000+ for custom headers is pretty normal. But then again they actually make power n/a.

Fuck that noise lol. I got it for very very cheap, used it for a while and sold it for alot of profit. I'd built my own before I'd spend that on a one. Ebay with collector mod ftw
