Does any out there have an idea on where I could find flowbench numbers for a set of stock 993s. They're 1.94/1.50 ,76cc. I've been looking for a while and can't seem to get much. Thanks Kevin

Here you go:

Lift__Intake__Exhaust
.050____25.1____21.0
.100____51.1____38.5
.150____76.2____55.0
.200___104.4____71.5
.250___130.1____88.0
.300___155.0____99.4
.350___175.1___109.0
.400___184.0___113.0
.450___185.0___119.3
.500___186.0___122.0

In case you were wondering the 993s beat out the 186 (nearly identical to the 993s but the double humps have a closed chamber) heads by about 8 cfm on the intake @ .500" lift due to shrouding by the closed chamber.

Thanks neighbor. Kevin
