The car just came out of the bodyshop and I didn't have the brackets to properly hang the bumper so it is simply resting with 2 bolts holds it "sort of on there." I'll let the pictures speak for themselves. I literally just picked it up a few hours earlier.

I'm doing my best to finish it by SevenStock 9/25/08. I begin work Monday on it.

That looks great. Gotta love gray FDs. Not really a fan of Petit flares, but it suits your monster build.

Motor/clutch/trans is installed. Now working on electrical/cooling/exhaust etc. Basically everything


I'll be doing some track days and then racing with NASA in their TimeTrial group. TTU or TTR whichever one my car is allowed to run in.

18x10.5" front +50
18x12.5" rear +50

offset stays the same. I simply converted my 18x10.5" rears into the wider size with new outer shells/halves from CCW. Even with a 335 out back the rim can accept a 345 or larger quite easily.

My engine makes about the same as the LS9 and has connecting rods rated at 1200hp. If I need more power I'll just spray it. It should make around 650hp flywheel.

Towed it down to SevenStock; however wasn't running yet. Too much to complete and some wrong parts were the culprit. Will be running in the next couple of weeks. Have a track day November 10th at Laguna Seca

JKL Racing GTC replica front bumper (makes Pettit bumper look like a joke) fits perfectly with huge inlets for gobs of air.
RaceShop chrommoly (sp?) rollbar
Driveshaft Shop 3.5" Cobra/T56 driveshaft with Spicer 1350 Ujoints, custom forged Cobra inner stub axles with 300M forged axles, and forged outer CV cages
Built the dual stainless steel 3" into 3" Random Technology cats, Burns 3" Ypipe into 3.5" single exhaust all the way back in the garage with a friend. Plan to make 550rwhp+ thru this setup.

Still have to complete fuel, cooling, oiling (dry sump lines/cooler/tank) systems and other misc parts.

Hey Mark,

The project car looks sweet! Is that my old FD's body that I sold you? If so, it going to be a monster!

Started a business and have been working my *** off. Sevenstock approaching time to finally finish the car. I really haven't worked on it since last year Sevenstock up until about a month ago.

Gettin' closer.... Mike is coming over to help me with the electrical aspect tonight which I hate doing.

The intake setup still needs a little tweaking; however the concept is there. Still need to cut a rubber hose and run it around the aluminum radiator top plate so that it doesn't rub thru the silicone hose.

I'm running a Taurus fan, Howe dual pass radiator, Evan NPG zero pressure coolant, and about the straightest air shot to the intake/TB you can achieve. Hood clearance is good.... but close. TB is a ported 90mm Edelbrock unit that has approx a 92/93mm opening tapering down to a 90mm blade. The mounting base of the TB has been milled downwards to create a 3* angle drop for better hood clearance. Thank you Sean for the hookup! (anyone needing their TB's ported it is $50. The machinist does work for Lawrence Livermore Labs Research Facility... nuclear etc...).

After I TIG welded the exhaust closed (it was tacked before) it moved a little from the heat and at the collector I need to redo one side. That shouldn't take too long. I have a Miller TIG Diversion model that is portable and can be carried with 1 arm! Probably weighs 50lbs. Does a kick *** job! Very stoked on this purchase. Turned out nice for my 1st project.

So the list is getting shorter... Getting pretty excited to fire this thing up! The parts collection is spanning over 2 years!

Some pics of the exhaust. Dual 3" from the collectors into Random Technology 3" cats (the Samberg trans mount provides gobs of room over the Hinson one and structurally provides a ton more bracing), then a Burns 3" to 4" "Y" that was butterfly cut down to a 3.5" section in the rear (my buddy Chris Coffey did this). The 3.5" then goes to a Magnaflow muffler which should sound good. If it is too loud there is a long straight section in the middle to cut in another muffler if needed.

When the two ends are butted up next to each other it is pretty simple to weld and you don't really need to use any filler rod with the TIG. When there is a gap and one needs to use a lot of filler rod is when it gets a bit tricky. But for my 1st time I'm happy with it. Blew a few holes in it, but repaired them and learned the signs of when a hole starts and to back off the foot pedal. TIG welding is actually kind of relaxing?!?!?

Still need to weld in a 3.5" Vband where the mid section is and then move over the drivers side exhaust about 1/2" (cut/slice/weld) where it meets the header collector. 10 days left until Sevenstock. It will be driving down.
