sorry i dont know how to put videos on here...

Are the pulls on the dyno sheet a before and after with the headers and pulley install?

no, the before (red line) is with the headers/ under drive pully on the original cam install tune. 436hp/394tq

this pic is the before and after on the cam/stock manifolds/bbk cair/ jba catless midpipes.

the numbers before the pully and headers on the first cam tune were 420hp/411tq
after adding headers/pully made 436/hp394tq.

then tuned again and got 458hp/408tq

hopefully thats not too confusing/ makes sense lol i had to read it a few times...

Wow! Nice gains from headers and pulley. It seems to me that you have the hp and tq reversed for the graph you just posted.

I don't think you can have horsepower peak before torque!

I'm kind of surprised that the longtubes actually lost peak torque but they sure as hell picked up plenty of horsepower. Could be different conditions on the dyno days as well I guess.

Edit: Maybe the pre longtubes dyno wasn't at Torq's? I dyno'd my car there with ls9 cam, cat delete pipes, vararam, and UD pulley and put down 415hp 384tq without a tune. On a dynojet baseline (before tune) it made 428hp 408tq.

thank you ! yah, haha, you're right about me having the numbers reversed and the pre longtube dyno wasn't at Torq's. i was also a little surprised with the loss of torque numbers but being that it was on two separate dynos i didnt get to hung up over it. it certainly doesnt feel like it lost torque. lol.

2013 1LE
ARH LTs w/o cats. K&N "plastic" intake, VMAX throttle body and a mild tune (car had 99 miles)
414 RWHP 408 RWTQ on a famously stingy Mustang Dyno

I took my 2012 Camaro 1SS/RS LS3 to Premier Performance in West Jordan UT today. My Camaro is bone stock with 2534 miles on it. West Jordan UT sits at 4330 feet above sea level.



Does this look about right?

You look to be right where you should be.

StainlessWorks LT headers, catback, K&N Cold air intake, and tuned by LMR

[Jeff_SS]

I have Kooks 1 7/8" long tube headers and high flow cats, a CAI intake, and NPP exhaust.
First pull on factory tune was 406rwhp and 392rwtq
After Ryne did all his tuning it put down 433rwhp and 415rwtq. (This was in 101 degree heat by the way)
AMAZING tune by the guys at CMS.

Here is the Dyno Sheet.


And here's the video I recorded with my iPhone 5 (so the audio isn't that great)

Here's my first time results from a dyno at a school here in town. Not sure what they should be or what gear I should have been in, It was kinda of a learning curve for us both. But it's 2010 ss 6 man in 4th gear, all stock. Some say I should have been in 3rd?
