Indeed. It's also alarming to know that someone buying this header not only loses tons of power, but limits there potential advance, or if they have already advanced, puts them at risk...

 

First one thing you need to remember is that his car is NO WHERE near stock lol. I would venture to guess that on a 100% stock car though wouldn't be much of a decrease if any, maybe even some possible gains, who knows. On a highly modified car, sure this shouldn't be ran but who knows. As far as the risk, I really don't think there is any RISK of running this header. If you are properly tuned for what you are running, there shouldn't be an issue.

 

exactly. this header should not be run on a highly modified balt. It will probably not make a big deal on lesser powered cars, especially not someone that only wants the sound. But it hits a wall really fast, and if you're moving any serious airflow, then this will hinder your ability to make any kind of real power.

 

wow that power decrease is insane, even with some timing dropped for obvious reasons.

 

Whats the next header you are testing. I just switched to a Clear Image Automative header and downpipe setup and I am very curious as to what kinda power gains/loss's you will see.

 

I'm going to be out for a few hours, but I'll get more info up when I get back.

the vibrant is next.

 

I guess what I was getting at, is that if someone had lightly tuned, lets say a 2.8, 60's, meth, and a comparable header/dp, and then decided they wanted to switch to this one believing the company that they would get similar performance, or more, and a mean sound, and didn't think the roll back timing after the swap...... You know what i'm sayin?

 

Yes and No. I mean I don't think the header was the cause of a lot of the knock personally. I don't foresee someone else having 6 degrees of knock on a 2.8 60lbers and meth if they are tuned properly with this on.

But still in general, this IS a poorly designed header from the looks of it and the dyno doesn't lie generally lol.

 

Actually, it is totally possible it IS the header causing the knock. I was able to go from 18* to 21*, no methanol, when I stept up to pacesetter header, full 3" exhaust. The restriction of the JBP spaghetti ball gave it garlic breath

 

thats crazy

 

That's about a 16% decrease (doing the math in my head, so it's not exact).

 

lol. cali buddies you seeing this?

 

cali ftw. a friend keeps asking me to move there. but I say screw CARB. So far we have stock header and JBP correct? (not reading every page up til now)

 

i know 3 guys in socal alone that were running this header. 2 of which will be running tvs's. hopefully this opens some eyes!

 

off the top, the header causes so many problems. The afr wasn't holding steady through any of the pulls i did yesterday. It kept changing during every pull we did today. The header has too many bends in it, and there are two different places where two different primaries are touching each other.

 

is the primaries touching..a problem? I'm thinking heat affecting flow

 

Next header please!

think harmonics. If you have frequencies that the ecm picks up as being a problem, the computer is going to take it as knock. There is an issue with the no.1 touching no.3 and no.4. It's going to cause knock and pull timing as a result. I had instances where the max timing was around 9 degrees.

The next one is going to be the vibrant. It's pissed me off already since I have to get a o2 sensor extension just to get the rear sensor to work.

 

Can't wait for the results. I'm currently running the vibrant until i have enough power to warrant a full hahn exhaust

 

I really wanna see the vibrant too! Even though I've cut out the cat.

 

I call bull **** on the JBP test. Even giving you benefit of doubt that you have a shitty header where your primaries are touching, I have one and there is another one here, neither have primaries that touch. Second, your tune is F'ed up or you have an exhaust leak for your AFR's to be all whacked, I would have that checked out first. I put down more power and way more torque than what your claiming with less boost and on the M62 on both mustang and dyno jet dyno's, even for disparity between dynos around the country, no way are your numbers believeable, I dont think you have a solid tune at all since your meth problem.
I am not a JBP fan by any means, but I think the communities hate for them is fueling some of this. If you have a JBP header with touching primaries then you have a bad header, and I highly doubt touching primaries would affect the knock sensor that bad.

Out of curiousity, how much air flow are you moving through the MAF, you know, when you had the stock manifold or when you get the vibrant on.

 

Pretty touchy for not being a JBP fan. But fyi, their shitty rep was earned

 

I was waiting for you to come. I am going to give you a chance to think about what you said. For one, I don't care if I had a bad header. Have some pride in your product and sell something that won't cause a problem. I bought mine along with about 30 other people during a group buy sometime last year.

Two, since you know so much, take the time to realize the differences between our two cars. I don't care how much you say you've done with yours, I can guarantee that you and I are doing two different things, and I am moving way more air than you. I will post my mods for you, since I don't think you took the time.

1. TVS- 1.32L air per cycle as opposed to the m62 moving 1.0L of air. Also, I am running over 22.3 psi max. That means I'm moving almost twice the air a stock one moves coming from a larger blower. So unless you have a tvs, I suggest you rethink your stance.

2. Ported head- The game is movement of airflow here. R.A.W. intake + ported head= more air being forced into the head. I also have forged pistons in there, so I can move up in boost if I so choose. The intake manifold is not a big restriction in my setup. I am more than capable to handle what the engine is sucking in.

3. Water-Methanol Injection- In place to keep supercharger temps down. Not really a major factor since we're talking about a header, but it is on the car.

Since you're so confident in the header, take a look at it yourself and think of what I'm going to say next.

 

Ummm....... Unpresidented? Srsly?

 

they meant loss not gain
