me loves my pacsetters armor coated header..its the ****..best bang for the buck

 

[QUOTE=bulletpound;4200988]I have the hahn 3". That is the one that will be used throughout this testing phase.

Some people ask because they don't understand what they are asking for. It was kind of open ended the way you asked it. Long story short, look at your maf reading at the top of one of your pulls. Your maf reading is going to be considerably more than a stock ss/sc up to 6500 lets say. And mine will be higher than yours as well.

 

same here, I just wish I had bigger primaries. I only have 1.5" primaries.

 

To all the people saying the test was whack...

Funny how when he puts on a real header... with the original tune... no knock, no afr fluctuations...

Im not sure if your trying to be funny... but... LOLOLOL its not working. We understand, you have a dyno sheet.. thanks... Now were trying to pay attention to the educational stuff about this header testing, so please... I dont care about your feelings, No one else does either.. Keep the sarcasm to yourself... If you have a problem, make another thread about it...

BTW... have you ever tried to get a hold of that damn company?

 

Rippin, you and I both know that when things like this normally happen, it's because there is a favoritism that is being put into play. I know that feeling was going to come to the surface when this was put out. I can't blame you for feeling foul play was being introduced. When the car went on the dyno the first time, things went fine, and the meth line didn't work itself loose until after the first pull, but most likely during the second pull. I thought from the design that things would be affected some but not to the level that we saw, and since we only got data from one pull, I felt better doing things again, since they wouldn't be believable from only one run.

Joe and I went through things again, looking for something that would stick out as a red flag, but nothing was there. The only answer for getting the car to run smooth with that header was to pull timing. And after 6 degrees for most of the area of the scan representing PE, it finally ran without issues. We pulled the valve cover to look and check for a broken valve or spring, since 52 horsepower being lost from one mod change is unbelievable, really.

After the dyno on saturday, it was run four times, three times back to back but the data was lost when it was transferred to a thumbstick. We had to strap it up again and do another to make sure that we at least had something. On the fourth pull, the dyno had a noticeable hiccup right about 5500 rpm, and some on here might not understand why there would be a break in the dyno sheet. I can post it though, on request if need be. But through the runs, the horsepower figures were within 7hp of each other. So at least I know the car doesn't heatsoak much, and the meth is working again.

Pulling the header saturday after the dyno spoke volumes though, where 3 of the 4 primaries was making contact with each other. I have the neutral balance shafts in, and the rotated mounts from ottp, both things that could be contributing to the great sensitivity noticed only with this header.

To answer another one of your questions, the afr would almost change on it's own. the car liked to run lean and stay lean at idle. Now with the 60's, it's a common issue that I deal with everyday, but normally the car bobs between 13.7 and 16.0. With the JBP header, the car would go between 14.5 and 17.2, occasionally staying lean for a number of seconds. I didn't figure it as a big deal, since it's not going to hurt the car being lean at a momentary idle. Also, it's kind of hard to drive a car ***** out when you can be heard from 3 miles away..., no kidding.

The jbp header, coupled with a gutted cti downpipe, and a 3" hahn exhaust could be heard by my friend who was standing outside 5 minutes before I got back to my house. I also managed to get a noise violation summons for making too much noise at 30 mph. The sound was very aggravating. Some say it sounded like a mix between a scooby and an exotic. Well, mine sounded like a mix between a scooby and a harley davidson. It wasn't pleasant.

You and I have common goals to meet, and all this blew up because of a bad product. The guys in my area like domin8 don't nut swing, they don't want someone to ruin this by talking out of their ass. I know you didn't come in here to do that, and I'm a humble person that just wants to know the truth. That's why I'm using my car to do it and not someone elses. This thread needs to continue on and your input is appreciated. I'll be getting to you through pm. I got yours yesterday.

 

all i have to say is everyone who bought jbp got robbed and now want to sell it for like $250 or someting cheap because no one wants it now. also once again YOUR JACKED AS ****! lol

 

how many headers are the same or very similar to eachother?

 

I'M ON A BOAT! LOL

But really, seven months on a ship will force you to do only a handful of things. I chose to workout. And thank you for the props.

The stock and hahn headers are close, with the hahn having smaller primaries. Vibrant and CIA are comparable, but the vibrant has a smaller collector than the cia.

 

Deathscythe, who ported your head, what are the flow numbers, and are you going to mod the JBP header like I told you?

 

The head was ported by m2race. It's the same company that ottp uses. The flow numbers are on their site. I have to go back and take a look at your recommendation again. After getting a chance to closely observe the header, I'd feel bad to sell this header to someone else. That's not good business. The header could be fixed, but it's going to take some time.

Have you considered sending your pacesetter out here if I can't get anyone else to get onboard with one?

 

I'm in Germany, the car is in Nebraska. I'd have to get my friend to take it off the car, wouldn't be hard though, just remove a couple bolts where it connects to the resonator. The head is back at the machine shop for more port work and the cams are at web cams for custom hardweld.

I'll talk to him and see if he's up for that. You know how much it would cost to ship a header and dp together in a long box?

 

I don't know, but I can try to average some numbers and let you know. There's got to be someone on here that can provide their setup. At least that's what I'm hoping. I'm starting to believe that a 3" exhaust might not necessarily be needed for most applications except the extreme.

 

My pacesetter is 1.5" primaries, 2.5" collector, and 2.5" downpipe. No cat. Just FYI.

 

sounds like it has potential. It's all welded together?

And how aggressive are you trying to go with the flow? What is your target cfm?

 

Yes, it's all welded together in One Piece. I wasn't really trying to target anything, just trying to optimize what I had. I bought the header for 40 bucks. It's actually for the 2.2 cavy. And the downpipe is custom, free.

Thing is, it flows really well, more than the stock header/dp that's for sure. So I would guess that you should put down more than your previous dyno on the stock setup.

 

I'm thinking myself, how much more could I get out of the head without compromising the sidewalls in the process.

 

I think m2race hogs those heads out plenty, if you wanted more out of the head, send it to someone that will work the bowls behind the valves a little more. That's where the biggest gains are, that and the valve seat.

Just porting out the ports themselves won't do nearly as much. It's all about velocity.

 

the only thing I regret is not being able to visually compare the ported one to my stock head.

 

let me ask you this, do you have a comparison at all to before the head was ported and after?

Cause my head flowed slightly less than the m2race head, although much higher velocity I'm sure, but that was my only change as far as power goes at one point and the difference was very significant.

 

well, after swapping from the tvs to the m62, I gained 25 hp from the same tune without changing anything. The numbers were 287whp/262wtq as opposed to 262whp/237wtq on the m62. After switching to the ported head and correcting minor afr errors, that produced the stock header numbers, 312whp/247wtq. This is all pretty much from the same tune, and I think that 25hp just from installation is pretty reasonable.

 

So you went from 262/237 with the m62 stock head, to 287/262 with the m62 ported head, to 312/247 with the TVS ported head, right?

The real gain can be seen when you add all that airflow to the mix from the TVS. Also, I can see why your tq numbers drop.

 

262/237 m62+stock head
287/262 tvs+stock head
312/247 tvs+ported head

 

did i tell you already that your jacked as ****? ROFL. hahahah

 

My friends call me 'cole train' from gears of war. I even sound like him when I get pissed off.

 

ah, I see now. my bad, either way my conclusion remains the same. I see why you lost tq. It's the velocity of that port job on your head. That is if everything else is the same, as in you didn't change anything.
