Reply to "Engeneering challange ... Progressive Throttle Linkage"

Hi Kelly, That makes all sense.
My engine is out of a V8 Starr racing class from around 2000. It had a common manifold with only one throttle valve. It is a 350Cu revving 8000 RPM. It has a "modest" 550 BHP and 615 NM. However the Torque and BHP curves are really flat. Car is ment for track day's
and just having fun without beeing affraid for the ZF.

As said throttle response is much to aggressive at the lower end. And if you start digging, you will find that this is a common problem with these setup's. I have talked to Kinsler. The progressive setup you see in Figure 3 is more ment for a common manifold, and not for velocity stacks. The total amound of air comming through your trompets will be mixed in the manifold before it enters the cylinders. Looking at it that way, it makes perfect sense.

Kinsler has a 600 usd solution though. looks great, but pricy. It will solve the problem completely. it is a evolution of the "jackshaft"
