I finished up my FMU intake install today, and all I can say is WOW!! First things first, the quality of this intake is absolutely phenomenal! The install was a little more difficult than I thought it would be, but everything on this car is. The directions were good, but not great, a lot of trail and error to figure things out. The intake looks absolutely awesome!! I did add some personal touches to give it a little C5 and C6 engine bay look. OK, performance wise, WOW!! The car sounds awesome, I can really hear the turbos spool now. I have a G-Tech performance meter, or a G-meter I call it. It is pretty damn accurate to, I would say within 5% of actual numbers. I did a 1/4 mile run in the car two days ago with stock intake, and another one today with FMU intake. Same weather outside, almost identical temp. I never would have thought I could see a difference this big from just an intake. I have enclosed pics, hope they attached correctly. These numbers might not be 100% accurate, but the point is, same conditions, same meter, and look at the difference ! Here are the numbers:
Stock intake: 60 ft - 1.99, 0-60 - 4.55, 1/8 mile - 8.4 @ 84 mph, 1/4 mile - 13.13 @ 104 mph
FMU intake: 60 ft - 1.97, 0-60 - 4.33, 1/8 mile - 8.1 @ 89 mph, 1/4 mile - 12.76 @ 109 mph
I would buy this intake again in a heartbeat !!
