Current set up is s&s headers with true dual 2.5" exhaust, Were going to give it a try. I may move over to a set of Neils larger long tube headers.

Just to let you guys know..... Scott have good taste...... The gangs from lextreme camp are just absolutely excited and can not wait for this torque monster to be release.

4.7L
Supercharged
6 Speed.

These specs sound like an upgraded 2003 SVT Cobra. SVT Cobra hit 500 rwhp with just a pulley, exhaust and reprogramming. I think you will get alot more than that. Scott, if you have any questions about the 4.7L swap, please let me know.

Damn. I knew it was going to be the end of the world via a SC.

Good stuff, I thought I was cool with getting an M90 haha.

Youre going to love the M90! Not to mention save yourself about $10 grand plus

The M90 with a stick is a whole lot of fun to drive for sure. This how ever should be a thrill ride

Well in the long run my car will be close to yours, with one less gear on the manual. I really can't wait

I do however have a surprise down the road and expect a good gain from it.

Good luck on the build!

For one, this project looks amazing. 20psi of boost on a 4.6L is some serious muscle: I can't even fathom the numbers let alone the frequency with which you will go through tires. I am going over coefficient of friction with my Physics class right now, and I am pretty sure this car would throw that all out the window.

For two, I just got my 1.75" stainless headers from Neil in today. They look amazing. I am going to take some photos and post them, but I could email you some high res shots if you wanted to see the craftsmanship up close.

Mark,
Some pictures would be great. I have been considering those headers. Especially with the value of the Aussie dollar.

Well there is a lot of debate on Lextreme regarding this. I know there is talk of the stock system not being able to support 20lbs boost and high RPM's so i opted for this.
Quote from john Cribb

"I think we're speaking in relative terms wrt the COP's and their outputs. They may be smaller than one of the existing coils, but they're still only having to spark a single cylinder (albeit twice an engine cycle), where the existing coils are sparking 4.

Plus there are no secondary losses as there are with a coil, a distributor, and 4 long high tension leads.

I don't think I've seen or read an objective comparison between the power output of a coil & distributor setup, and a COP setup. That would be an interesting comparison."

That being said I know there are guys that have taken them to nearly 20lbs boost. There is a guy running distributer ignition on 17lbs boost at 7000rpm and he has had to close the plug gap up to make it work, he says it is maxed out, I hope this will support what I need, if not I will go to a CNP (coil near plug) system.
