Dyno Game.. headers LS2
Well guys i should be getting new headers on tomorrow.
I have an LS2.
Halltech Venom Intake with holes in the shroud.
Corsa Extreme Exhaust.
ASP UD Pulley (only have it because of the stock one crapping out, didn't have to pay for labor though
)
I am going to put on the LG Pro 1 3/4 Headers tomorrow.
Any guesses at final numbers?

Well to add, this was a different dyno mind you, when i had it tuned before with just exhaust and intake i had 357 at the wheels SAE. It was 379 but it was cold in Feb like 40 outside.
See if that changes anyones ideas. I should know tomorrow try to post before and after dyno shots as well.

Generally speaking I see 380-390 or so at the rear tires on average from the LS2 cars.
My 2006 did 383rwhp / 383rwtq with the headers, tune and no other changes not even an air box.
3" Borla and Halltech put me at 392/394...added a FAST 90mm intake 402/410.
Starting on my car was 357/348

Ended up at about 370 each, don't have it in front of me to be exact as the printer wasn't working.
Baseline was 358, now just FYI i did have a previous tune so some power was there already.
I think top HP was 373 and torque was 369, but under the curve there was a max of 30HP and tq gained in the mid range.
Also learned where the LS2 falls short on the heads and airflow on the top end. Later on thats my next big one is heads and a cam and the FAST 102 to put it around 450 i would hope. Much later on but gotta have something to shoot for next.
Either way it sounds SICK and ill enjoy the midrange gain during my HPDEs.!

To the OP: seems like 386.7 peak hp would be good.

Mustangs may show up to a 30% drive-line loss, it doesn't matter if you know the gains & losses.
What were your dyno operator comments?
What are the numbers form previous cars like yours on that dyno?
