QTP HV headers HUGE dyno #s!
Well my friend, the dyno doesn't lie. He said he has all the graphs. And you have to remember, it's not just one LT to another. It was regular LT's to LT's with high velocity merge collectors and a larger Y-pipe with Flowmaster collector, with no tuning. That's where the gains came from.But isn't paying 3x more for stainless headers that put out some awesome numbers and don't rust within a year and most likely won't ever rust worth it?!
Ok, tell Durien to post the graphs up, and you might want to look at this post.

Here's a quote from that thread.
He pulled 339 on the old set up, he pulled 349 on the new headers. Where the **** are you geting 18 HP Gain?
You can not go by what your car put down before. you have to go by same day same dyno testing. When you car came into the CARTEK for the cam it pulled 339 not the 330 that you had in your sig. The when the new headers were put on the car pulled 349. 10HP is still a very nice gain.
I saw the graphs, I was standing next to Rich when he sent them to print. QTP makes and awesome header, but you need to learn how to read dyno results. Has to be tested at least same week, not 6 months apart.

QTP's are good headers but their not magically better than other headers even with the merge collectors(maybe 5hp there).
no alex is wrong.... i am calling Dave@Cartek today... the 339 i believe it was after the QTPs went in and with the cutout closed through the stock muffler...
I couldnt go to the track yesterday do to rain threats... but i am going to a different track tonite (english town) after i come back i'll post up the graphs

What are the specs of that cam?
Also on the QTP headers graph, it looks like the torque curve improved all thru the range 10-20torque especially at the low end.
The hp looks like 10 more thru the curve over the Jet Hot LT's.
I'm sure the flowmaster collector on you're y-pipe helped with at least half of that gain and the merge collectors the other half.
I had a custom y-pipe with a flowmaster collector for my Jet Hot's, but a 3" x-pipe blows that away in terms of flow.

Some people are still saying you dynoed the car on 4/21 with the Jet Hot's and made 339 and then with the QTP's 349 that same day.

Also, what was your a/f with both headers?

i dont care. the dyno #s are there. and those are the sheets i have. I have no reasons to lie . I dont have the other dyno sheets. There were a lot of other dyno runs for tuning, cutout open vs. closed and so on.
How hard is it to get Cartek to print you out dyno runs 2-6 on one graph and post it up?
If I did this headers test I would have posted the graphs and all the runs when I started this thread.
i dont have a scanner or a digital cam.. it took me for ever to get some one to help me post those 2 graphs i have lol...
they didnt give all of their graphs a lot of them were just for tuning purposes and stuff
i'll get them all up one day... but i am not going to go out of my way to do it neither.
maybe by late next week..
i am too busy trying to get the car to run down the track and get a good # out of it.. its gotten to warm out and its hard to find a good DA
and to make it worse.. finals are here.. I HATE SCHOOL..lol

Thats ok Durien....people are calling BS on my numbers too....We do it for fun and thats all that matters........

First we had the deletion of the thread on LS2.com...now you're comparing a baseline dyno with the Jet-Hots to a second dyno with NEW HEADERS AND A TUNE
What skewed information.

i wonder who sent you to post that... its obvious you are some else registered under a different name... i am pretty sure who you are..
nice dirty business you are running..
the ls2.com thread was deleted because it was getting out of hand with all the bs and jokes..
as i said before... .i dont give a F*ck what any one thinks... my car has always run the # and i will continue to do so!
you can go back to the crap whole you came out of and keep your dirty business practices to your self
ah and do me a favor tell Benson@TTP i said hi

lost a ton of low end tq in exchange for uptop power...looks like you might have to set that shift light at like 6700
