[Turbo99GT]

If you went with a TDC setup, you would be very happy. I have had it since August and 3K+ miles later, it's still running strong. The last thing I would worry about is a Kenne bell blown 4.6 on the street. He may get out on me like most cars, but once the turbo is spooled, it's all over. A highway race wouldn't even be close. I had a V2 S-trim @ 12 psi for over a year and it's not even close to how the turbo pulls from 80-150 mph. A turbocharged Cobra would be insane. I can't wait to get a ride in one. If I can put my bone stock long block 2V in the 10s with 16 psi, a Cobra would be a rocket with 16 psi. If you decide to go with a blower, get a centrifugal. People say that roots and screw type blown cars are faster on the street than centrifugals. That is not totally accurate. Any person with a centrifugal will usually have it geared or have a loose enough converter to compensate for the delay in boost. I would be interested to see an 1/8 mile test between roots, screw type, centrifugal, Spray and turbo 4.6 2Vs shootout in a magazine.
