i knew you would figure it out. i guess the whipple and loud exhaust thing gave it away. i bet if it said boomtubes that would be a dead give away. but i'm planning on doing my clutch, flywheel and DS too as soon as i get out of the empty wallet crew. lol.
I just installed a new clutch, flywheel, pressure plate and slave cylinder in my 2007 GT. It has been in for a whopping 24 hours so I can't truely evaluate the final outcome being it isn't broke in yet. I went with a Fidanza aluminum flywheel, Mc Leod RST, and a new slave cylinder from Rock Auto. The engagement is closer to the top of the pedal travel now but is as easy as stock to push.
The main reason for my post is to let you know that, unless there is something I don't know, you WILL have to remove the Whipple to get the tranny out. I read about this on another site but thought I would try it without removing the S/C. I was able to remove all of the fasteners but I could only move the tranny back about 1/2 inch before the bellhousing hit the tunnel. The engine has to tilt down in the rear substantially in order for the bellhousing to clear the tunnel. The S/C is so close to the firewall, it limits the amount of engine tilt.
Removing the S/C is pretty easy as long as the car is on the ground but being I had it on jack stands I just worked off of a step stool to get it removed (I won't make that mistake again). To avoid a big mess if your Whipple is intercooled, you will have to remove some/most of the coolant from the intercooler. I did this by siphoning out most of the coolant from the I/C tank. Then removed the short return hose from the S/C to the tank. Next I SLOWLY pumped LOW PRESSURE air into the outlet port of the I/C which pushed the trapped coolant inside of the I/C back into the tank. Note: you will have to siphon out the tank at least one more time to get all of the coolant out of the I/C. Then I remove the other hose to the I/C and capped off the coolant ports on the S/C. By doing this I was able to remove the S/C from the car without spilling a drop of coolant. It sounds a lot harder than it is and only took about 45 min to have the S/C off. Once it was removed, the engine tilted down and waaalaaa, the tranny came right out.
I did the complete clutch replacement in my garage on jack stands but just one word of advice if you're going to attemt it without a lift, be sure to raise the car way up. With my car as high as I could get it, I still couldn't get the tranny out from under the car while on the tranny jack.
Good luck with your project.
