I had my car tuned and dynoed with the maggie, numbers where 441hp with 417 torque. I expected more. Mods are kooks with HF cats, 160 stat, 60lbs injectors, ls2. Just wondering what other people dynoed. Tuner said a meth kit with crank pulley will get me close to 500. Just wondering what you guys felt. thnks

I was at 452 and 429tq. This is with stock ex manifolds, magnaflow mufflers and a volant intake. This is with the stock Magnuson tune. Where are you located what was the outside air temp and conditions?

Also peak numbers don't tell the whole story. The real question is are you satisfied with how it drives now?

When you start getting into the 500hp range you start running out of gas.

The drive train loss in the V is very high also.

"Outside temp and conditions" does not play a factor as long as a correction factor is being used... thats the whole purpose of a correction factor with the dyno. To include humidity/temp/ambient air pressure. I always laugh at guys that say.. it was a HOT day in the dyno shop.. yet you look on the dyno run or sheet, and it has the temp (which is used to correct the hp and tq values).. means, if you are using SAE.. .standard automotive Engineering standard calculations are used.

what WILL affect hp/tq however, is altitude /elevation.
You will not make as much psi if your higher up, and since PD blowers are belt driven and not wastegate controlled like a turbo, you will lose psi and power with elevation change.

Heat soak is the other positive displacement devil...

Try dynoing a car in Denver.

My car through a few mods was .81 drivetrain loss. - ~19%.

GFallen

04vguy what pulley did u change to reach 9psi? Im in eastern PA outside temp was mid 70's. The car feels great BUT im wondering if i could have went with a CAM and spent half the money with similar results. I guess I just am neversatisfied! sorry fellow member neversatified. lol

ive heard a guy dyno at 425 hp with just the maggie 6 lb and all else stock. this sounds about right...

he had an ls6 though so idk

Didn't see it yet. What dyno? 441 on a Mustang would be nice, on a dynojet kind of ok, on a hub dyno with the wrong correction factor who knows.

Numbers don't sound terrible for peak. Show us the graph. I'm guessing that 417 tq is down around 3k rpms. My 360 tq cam only is about 5k. No comparison at all.

(My wrx makes more tq than my V down low

My buddy all stock but maggie 05 ls6 made 425, but cats seem like they are taking a **** because he drove so long without a proper tune. Tuner said with headers and exhaust 460-475 should be around that range. Dyno jet dyno

It was technical 8.8 psi and it was with a 2.6 pulley from pulley boys.

mp112, obx headers, muff delete, comp cam, and im at 490rwhp

Meth and pulley coming next to put me over the 500 mark then i'm done

Those are corrected numbers? Seems a bit low but dynos do vary a lot. What boost nos were you seeing?

who wants to sell me a kit? I need BOOST now. Or I fear I might try and buy a rustang... GT500.

You are the one I was actually talking about cause I spoke to your friend and he told me he dynoed it earlier that day at 425 or so...
