Just finished doing compression test with the help of my father-in-law. Used the procedure from the c-speedracing web site, with the addition of grounding the spark plugs in the wires to the exhaust manifold to avoid distributor coil destruction ... I wasn't sure if popping the 15A ECU fuse did that, or just prevented fuel from spilling into cylinders. Anyway, enough of that ... on to the results:

Cylinder 1: 228
Cylinder 2: 225
Cylinder 3: 230
Cylinder 4: 230

This is a 95 B18C1 with about 110K miles on it.

 

good solid numbers across the board. Hope mine will be that consistant.

 

Not bad at all. Pretty high actually. You seem to have yourself a good strong motor. Is it all stock?

 

I have the Injen shorty intake, and an ITR intake cam ... the one with the less aggressive grind.

Motor feels strong ... I would like to mod it some more, but I am not sure if header/exhaust would free up much more power. I am not sure what is holding the car back, I can trap 90mph at the quarter, but the fastest pass was 15.6 before the ITR cam went in.

I have heard with that trap speed I should have a better time.

 

if you get a header and exhaust that cam will free up a lot of power and let your motor breath better since you have that cam.....

I pull the injector clips for a compression test.

 

Those are some damn good numbers for a '95 GSR!!!

Actually, the performance specs for a stock GSR is approximately 15.5 @ 90 MPH so I think you're pretty close to that. With that trap speed, your time wouldn't be significantly faster, if you know what I mean.

 

damn Ive got a stock 98 with 50xxx and I thought my 225 across the board was good...
