A dyno pull of a bone stock JDM H22 Prelude, with Bisimoto V2 header, and exhaust cutout. On board is also an S300, AEM V2 intake and 440cc injectors. Peak power of 196.4whp!

12G - They don't have any dyno runs prior to the installation of this header. The motor has mild modifications with a tune. If it were a 100% stock H22a or H22a4 motor (in a prelude) with before and after dyno results than it would make many Prelude owners happy. But they have yet to do so since the day they started producing this header.

Any Bisimoto claims are hard to believe for me now.
It seems like they think a ati damper can make 45whp. I asked other highly respected people shops that sell the same damper and they tell me not to expect any power gains no matter how much power you're making but it will make the engine last longer. This is just one example of bisimoto.
There is also another header debate on HT that their "custom" header makes the same power as a replica which is half the price.
everything always appears to be "cutting edge" based on the advertisement they give.....yet it turns out to be the same cutting edge technology everyone else already has.

If the site blocks out part of the name, it's prelude p o w e r
If there was a simple before and after dyno (even if it was tuned on both) it would be of better use to us than throwing it on the car and doing a pre tune run and an after tune run - on the same header. Where's the comparison vs stock? We need proof of the actual average gains from the header, so a simple before and after is all anyone is asking for- It's not a hard thing to do but yet nobody has produced one.

it wont idel and im not sure if all the vac lines are hooked up right
can some one please help!!!
need a map or something i dont want to pay $1000's to fix
Posting this in the 5th gen section would give you more results vs thread jacking an already crapy thread.
Well, for starters you're using ITB's - which doesn't give you much room to adjust. That car won't pass your typical cali inspection from what I know (don't live there, don't take my word for it).
(and that header is junk)
That's alot of work done to the motor, if you're really running it without the proper map than you need it tunes ASAP. It will cost a couple hundred if it needs a tune, or a couple thousand if you mess up the motor. Rule of thumb: never buy someone else's project. You never know what you're getting yourself into. (unless he had documented everything and you are in contact with the shop that did the work)

So there's your answer, it's a Type S motor. That alone is going to account for 15whp.

Ya it's old, but so are almost all the posts in NA. The point was that the header wasn't doing anything special compared to any other header, but I think you just wanted to ras me
