Interesting...the interior is a bit too loud for me.

I love the coordination in the engine bay, procharged L36's are pretty ballsy. How much power does it put to the front wheels?

Any other shots? Curious to see your wheel and tire combo.

maybe keep it black with some red as accents with a tiny tiny bit of white as a divider between black and red..?

325HP? I'd hate to sound skeptical, but do you have dyno sheets to back that up? Those numbers are high for a supercharged L36, considering they lose a decent amount of WHP through the drivetrain.

*edit*

I'm surprised you're still on the stock 16"s for all the work that's gone into the car. A nice drop and 18"s would really set off the exterior.

im kinda with chris here. that must have been some generous dyno because most things with 325 whp are going to pull way better than a 14.1

hell my g6 got close to that and it was no where NEAR 325 hp

yea the GXP G6 has done a 14.3 at its best with every performance upgrade it CAN handle without spray and thats like i think 379? to the crank

Something is just not adding up here... I mean, 325HP... 14.1 on the 1/4? Either whoever tuned it for you is a blithering idiot, the dyno numbers were way off, or you're having a serious traction issue on the strip.

I've seen GTP's with just intake, exhaust and a tune, not even drop a pulley size, and run mid to low 14's, while only putting 225-240WHP.

Something is seriously amiss here...

Yeah not calling you a liar or anything but I have to agree. the van weighs 4300 lbs and I only have 200-210 whp and I had it timed with the Torque app and I ran a 17.1 1/4 mile. 0-60 in 8.9 seconds, like the guys are saying, somethin just ain't adding up

i talked to a good friend last nite,asked him where i can get a dyno done,i told him where i had it done the first time and his comment was you would have been better off having a girl scout do it, he is going to check my tune and go from there.... didnt mean to make a big issue here

It's not an issue, it just caught my attention.

I know a few GAGT owners who are boosted, they're in the +300HP range, and they lay down low 13 1/4 times...without slicks. The fact that you said it's putting 325HP to it's front wheels, and factoring the drivetrain loss from the 4T65E, you'd be making 375-385HP at the crank. That's A LOT for these motors, especially when they lay down between 170HP at the wheels bone stock.

To boot, that blower has to be around +10 psi to make that much power on the motor, plus, you'd need a decent amount of internal work done. Forged pistons (for boost and drop the CR) forged rods, higher flowing heads, stronger valvetrain, bigger injectors, bigger throttle body and intake manifolds, that's just for starters.

not to make you feel bad or anything but the guys are right.

My 4th Gen Eclipse GT 6spd was stock at 263bhp and only ran a 14.7 in the 1/4. WHP is a different story, I calculated the whp at about 223 approximately and that was at a 15% loss to the drivetrain. typically that is about the percentage you lose from crank to wheels for a FWD car.

hope that helps.

i understand where your coming from,i was looking at the paperwork that came with the blower kit,there are 5 diffrent stages,stage one is 5-6 psi boost

stage 2 like mine,10psi boost and so on,stage 5 there claiming 550 at the wheels,is it true,i have no clue,but anyway,once the toon is done im bringing it elsewhere for the dyno and will keep ya updated

A Mustang Dyno is the most realistic/accurate WHP reading you'll get.
