I was watching this you tube video, and was wondering what kind of transmission this was.

Any ideas?

It sure goes fast.

Was in the lead at Laguna Seca until they lost it on the last lap.

They still made 3rd place

Does it rev match or does he use a clutch?

When I was watching it I noticed how fast the shifts were.

its a sequential, there is no clutch.

afaik, they still blip the throttle when downshifting.

It's a Daytona Prototype 6 speed sequential shift gearbox. I got that off one of their tech cards I got at the VIR race.

Daytona Prototype is the class they race in.

Daytona Prototype is the type of gearbox used. The DP cars have a special gearbox and SpeedSource just happens to use it. I can talk to Sylvain tomorrow if you would like...and they run in the GT class...wow.
