Near 105 Psi

 

sorry......it said the first reply did not go through....Hmmmm

 

awesome link thrash!

you need to know the cam timing to answer that question and cylinder leakdown. I have an excel spreadsheet that is pretty accurate calculating cranking pressure.

for example:

ENTER CAM SPECS (Rated at 0.006" Lift):
I. Duration = 242
E. Duration = 242
Lobe Center= 105
Advance = 1

CAM TIMING (Calculated):
I. Open 17 BTDC
I. Close 45 ABDC
E. Open 47 BBDC
E. Close 15 ATDC
Overlap 32 degrees

132psi @ 2% leakdown @ 6.5:1

 

Thanks guys. My banshee "aint got no cam" [img]i/expressions/face-icon-small-wink.gif[/img]. I was just wondering because the manual says stock 6.5-1 compression ratio and it blew a 130 Psi on the gauge. I was just wondering if it was high or low.

Thanks

ScoobyDFW finally landed in NY? THats a big jump. Anyway, Scooby is a thumper guy and has probably asumed he would help with some 4 stroke stats....which is cool.
130PSI on a stock Shee at sea level is a little high....but a little high is good..[img]i/expressions/face-icon-small-smile.gif[/img].

 

My 03 was at 125 psi both cylinders @ sea level after about 3-5hrs on the motor. I checked it when it was new so I know when it was getting low later in life.[img]i/expressions/face-icon-small-wink.gif[/img]
