Which one gives more horsepower?

 

Some one help me out!


PLEASE

THANKS

 

First off what is the intended use for said headers? Are you using this for the street for NA racing? I would think about that first before looking into a Bisi header.

 

both , allmotor

 

The bisi header is expensive but i hear it gives very good power gains. If you got the money go bisi.

 

The Ericks racing header is made by the same fabicator as AN-R. In other words they are the same thing.

 

wouldnt you need some dyno numbers to answer ur question...instead of a poll O_o

 

we run an ericks racing exhaust as well as the 70-72 TB on our race car and couldent ask for better products.

any one have dyno results thanks -chase

 

this is the 3rd or 4th topic you have asked about the same thing. Is this going to be an everyday occurance?

 

no no one was answearing so i put one in tech

 

bisimoto you all like that one how much horsepower can you get from it no its not a millon 2

 

Don't make multiple topics, bump up your existing topics, sometimes people read and don't have time to answer, be patient, you will get an answer

 

i dont think anyone has a dyno test with these brand headers.

yeah, its odd how all three brands came out at about the same time, all from so. cal., and all look really similar.

 

I'm wondering how many people who voted actually own one of the headers listed or have at least seen dyno results or butt dyno results.

yah...

 

i have seen Dyno resuslts from the Bisi cause they are posted on exospeed

Also i have driven in a car with a Bisi header and a car with the AN-R and i must say both are impressive, but to me it feels like the Bisis pulls harder than the AN-R. The old school AN-R's i think were better. The ones that looked like they needed 3 ft of clearance.

 

They are all made by the same fabricator but they all have slight different designs depending on motor set up

 

I think AN-R makes all of them. I remember about 3 years ago when AN-R made the first one like this.....oh well, but there are some numbers for bisi header

 

Actually none of the companies who sell the manifolds make them that's why the talk against each other why each one is better yada yada. If it is the same it's an old motorcycle header fabricator making these.

 

Only "eight" horsepower gain!

actually it was 8hp gain and im pretty sure that is WHP. pretty damn if you ask me

 

8 hp and 3ft lbs of torque at the wheels. Pretty damn impressive.......but that is hwat you should expect from a 600 dollar header

 

That header looks pretty good. Anyone have a dyno with a DC? Be interesting to see it against it as one is around 350 and other is 600.
