My GT350 after headers, intake, tune and E85 dyno results

[Trackaholic]

Great video. The sound on the dyno was pretty amazing.

sounds really good....was looking at the same set up...now I know wut it will do

Sounds crazy. Good.

Regarding Dyno numbers in general, they are pretty worthless unless you are using a consistent correction factor. For example, SAE with a smoothing factor of 5. If everyone used the same correction factor, it would be a start for relative comparisons. But nobody seems to. And I guess customers don't seem to ask.

No, not looking for stock parts. Just curious on the exact set up. Thanks for the info.

I'm pretty happy with the sound of the R, but it's not my daily driver so I wouldn't mind if it gets stupid loud.

Was looking at Kooks or ARH. Why did you opt for Kooks?

Haha stupid loud is a perfect explanation of how loud it is.

To be honest I just looked into Both and I came across more video footage at the time for kooks and how it sounded on videos. You really never know how it will sound until you hear it in person.

I'm sure both are basically going to give the same results etc.

The kooks just worked for me. I would be interested to hear ARH and kooks comparison in person!

+1 to video with no music.

An in-car POV would be nice, too...

Sounds fantastic, though! Must run like a champ!

It's been pouring rain down here today so haven't been driving the gt350 but as soon as it's clear I'll snag some POV video, bumper, and drive by shots.

Sound it makes is new (almost nothing like stock) high pitch for sure and louder than you think. Originally when I watched all the kooks videos I could not tell how loud the volume would have been in person. If anyone is considering LT headers you better be ready to terrorize your communities. Hahaha I'm thankful for dual mode exhaust though. On normal its very tame.

Wow that is loud. Do you daily that monster?

 

[TDC]

Sounds sick on the dyno.

I don't know much about the technical workings of dyno but I do know dyno is only a tool to find change in power curve and starting/end points and the end number is only relative to the beginning number in similar conditions.

I wish there was an exact setting everyone ran on a dyno so we could compare apples to apples.


The shop I had do the work has two configurations.

1) the "heart breaker dyno" - this is their truest read on the wheels and it's SIGNIFICANTLY less than the other confirguration - my number on this set up was 462hp to the wheels
2) the "dyno jet configuration" which is supposedly the configuration closer to dyno jet numbers which majority of people claim on their cars my number on this set up was 542hp to wheels

Here are both copies. I'm happy with either number but of course it's more exciting to post the higher number right?

Very loud. I used to daily drive it but recently got a truck so I only take it out once or twice to work during the week and then once or twice on weekends.

I finally got around to getting some video footage of my car with the headers installed, intake, tune and e85.

Parts list:
Kooks long tube headers
Kooks high flow race cats and x-pipe mid section
Jlt intake
Jlt catch can passenger side
Jlt coil covers
NGauge
Lund flex fuel tune
E85 in the tank

Didn't do starting dyno since plenty of other have done baseline runs fully stock and pulled numbers from 440-460 range (I assume dynojet numbers)

Installed the headers first and then the intake and tune second. Then ran all the 91 fuel out of the tank.

The most significant gain in hp was felt during the switch from 91 to E85 fuel.

As you know the long tube headers make this car deafening loud. I'm not joking it's probably the loudest street car I've ever heard in my entire life. Just rediculous. Video volume x100 in person loud. Personally I would prefer a little less volume but I have 0 regrets with the changes from stock.

Here is the vid I put together with my GoPro. Audio is not the best but gives you a little idea of how it sounds now.



And the dyno chart for those of you interested.

Let me know what you guys think

Thanks for posting. I am about to have the same setup except with the ARH system. Did you have a tune revision after the long tubes? Jon Lund is telling me no need to but curious what you did. My system should be going on in the next few days. I'll post my numbers when I can get to a dyno.

Interesting, perhaps Lund has added the changes from Voodoos car but I have not seen a revision from them, and I know Lund has sent him updates after adding fuel.

I would not run the FF tune with long tubes without a quality Wideband on a dyno to be sure it isn't lean.

I would PM Voodoo.

 

[WhiteyDog]

D*mn, those are some nice gains!

I have SAE corrected numbers. No Cats, no air intake, 525.8 rwhp. His numbers are still very stout for having high flow cats.

Did you noticed the on dyno sheet that it reads Flywheel Power HP?

 

[altjx]

I've already pulled the trigger on full ARH, but I'm dying to hear more exhaust videos of your setup. This time without any extra noise. No sneezing, coughing, music, etc. :lol: Jk man but yeah I'd love to hear this without music, lol.
