    Let's discuss.

    I talked with C&L and they will have their Mass air, inlet tube and pulley and tune avail soon. Probably the first engine mod I will do. Their pulley will include the snout so you don't have to have a puller.

    Course I've mentioned the glass roof we are working on.

    Exhaust most likely will be the Corsa.

    I will have some mock up renderings tomorrow of the exterior.. ;)

    Chime in... :)

    I have seen the K&N CAI put over 20rwhp at a dyno day I went to a month ago. I have also seen a custom tune give a GT-500 40-50rwhp with no other mods.

    My buddy just purchased a JBA 3" Catback for his GT-500 and it sounds sooo mean. It made 30rwhp over the factory 2.5" setup on his GT-500.

    He purchased it from a place called JBARACING that had tons of them in stock. They sold me my 3" catback for my Cobra a week ago and a guy named mike gave me a great price on my kit.

    JBA makes a set of long tubes, H pipe and cat back system for the GT500 - most of the major Mustang shops can get them

    I keep telling Lee to get me an intake so I can dyno it, come up with a tune, and post results on the forums. Up until recently there were very few intake options. Now we have the KN, steeda, JLT, PHP, C&L to pick from.

    These cars pick up a TON with a good tune. I have made almost 500 at the wheels with just a tune on an otherwise stock car, but that was a very cold day. Most see 480-490RWHP with a good 93 oct tune. Most come in at 425-440RWHP stock, sometimes 450-460RWHP if its cool enough out. There is a very drastic relationship between spark timing and post-intercooler air temp, anything about 100F causes a sharp drop off in timing.

    LTs don't seem to make much in terms of peak power, even if you pick up 10-20rwhp under the curve they add a lot of noise.

    As one said, with a tune, intake, and 2.6 pulley you can see 540-550RWHP.

    I plan to do tune, intake, pulley on my car. Then comes a bigger blower, and eventually turbos.

    Justin,

    We need to tag up on Lee and get a system over to you so we can get a tune done and get a system setup on my GT500. I'll be going to Tulsa in 2 weeks with our car. Think a few mags may cover the car then, would be awesome if we could pull something off by then!

    Got a graph? I have worked on some GT500s with exhaust and was not impressed.

    Nice numbers.

    I will be installing the C&L system tomorrow. No time for dyno but they are seeing between 60-80 HP with the MAF and Tune.

    NOT A FLAME, but a complement.

    Hey guys:

    You have me intrigued. I am very interested in the 500, and continue to try to get the wife on board with the idea. I have a high hp n/a Vette, and have had 8 mustangs and a s/c lightning, so I have always been a Ford guy until the past few years. The only, ONLY way I'd go Mustang again is a GT500, for sure. I miss the whine I have from my Lightning, and it ONLY made 411rwhp. If these 500's are durable, I mean durable, and I do not have to worry about rear windows falling out, or bad trannys, or hoses falling off the block, and can be modded with a KB, I am back on board, especially after driving an acquaintence's stock 500 the other day and finding Bill Ford is no longer there to ruin the company.

    Y'all convinced me...Good job :)

    Next are 305/45R/18 Nitto drags ....will go great with the 4.10 gears. Will make them about a 3.93 ratio. Just perfect for the 1/4. And fill in the stock ride height tire to fender gap nicely too
