I don't want to divert this thread but would a shaftless single TB (cable actuated) design benefit a 3.2 carerra?

The individual TB set up looks great.

Brian from Reno Rennsport. A customer of ours informed me that there were some posts on here regarding the Shaftless throttle design from AT that we adapted for 911 engines. Happy to answer any questions.

We originally developed these for our Spec 911 cars as competition is very high in the class and small gains are of high value. But now we have been using them on street cars as well because the performance was a bit more than expected.

In short we have seen improved port velocity leading to power gains starting as low as 3500 and of course top end power was much improved also.
Throttle response is also greatly improved as the butterfly can be placed closer to the head and still have clean air.

We are currently working with AT on a drive by wire single throttle which should be ready sometime this summer.

thanks.[/QUOTE]
