No, you can't tell what compression (static) you have in your engine, from that 190 psi reading. If you think about it, you'll realize that the cam's overlap has nothing to do . This is a low cranking compression, especially when you compare it to engines like the ZZ4 350ci/345hp crate engine that makes around 190 psi or the current HT 383 with 9.1:1 compression and a. i did a compression test and came up with 120 psi. i thought it should be around 160 psi with the head shaved .035". i took the jug off and inspected. Compression ratio is how many cubic inches you are pushing in to the cc's of the combustion chamber. Cranking pressure will have alot of variables cam overlap or ring seal .
The force of compression chases that oil around the rings, finding and sealing some of the smaller gaps. There is 190# of pressure trying to find a way out. The oil is pushed .
Tuning Engine Compression
There is a relationship between static compression ratio (ie 11.5:1) and cylinder pressure (ie 195 PSI). One problem is that cylinder pressure can be expressed in a few . C4 Tech/Performance - L98 compression test - Getting a nicely consistent range of 152-157 psi across all cylinders in my 91’s L98 engine. This is a high mileage car (~180k). Is . Did a compression test tonite and it was 190 psi can you tell what compression from that reading or does the cam overlap play into effect ? motor is a 70 460 .060 over with 68 429 heads c8ve-e and trw flat tops. 84 hatch scj headed 472" on 10" tires. Save Share Hi there. I just ran a compression test on my failry newly acquired RM. Cold Engine, throttle wide open. Did 5 kicks and it registered a somewhat disappointing 170 psi. I redid it with 8 kicks and got reading of 190 psi. Repeated this twice. I seem to recall my YZ250 registering a little over 200.
Removed both spark plugs and grounded them. Hooked the compression tester on the front cylinder and turned the motor over with the starter a couple times. Getting close to 190 PSI on the front cylinder. .
My compression test results
The compression tests results were 180 190 190 180 psi for the four cylinders. The field manual for your engine should say what the specifications are for a compression test. In the case of my miata, I was looking for 128psi minimum, 182 standard, 28 psi max variance. exhaust corrosion 2002-2005 ish 3.3l yamaha and mercahama four strokes. f200, f225 and f250 all have potental issue. some incidents found in bookend year motors like 2006 so be safe and have leg dropped and camera scoped. compression should be taken when motor has been warmed up and throttle is wide open. motors worthy of purchase should be at least .
210 psi compression? ***? . Cylinder pressure over 230 lb. would require an O-ringed block. I set the intitial timing advance at 12 degrees with 190 degrees coolant temperature. Any less initial advance in an attempt to reduce detonation on pump gas would cause the engine run over 225 degrees and if it was not for the zero deck clearance, the .

The KFX should have nearly 190 psi compression based on the stock compression ratio and the camshaft profile. But the decompression system opens the exhaust valve when cranking, and drops the compression to 65 psi. . I'm sorry, but I just can't appreciate doing a compression test with the decompression system leaking 2/3 of the . I'm sorry, but I just can't appreciate doing a compression test with the decompression system leaking 2/3 of the compression out the exhaust. Here's what's happening. The KFX should have nearly 190 psi compression based on the stock compression ratio and the camshaft profile. 190 on each cylinder . Save Share . you're not looking for higher psi's if you're just doing a compression test. you just want even compression to show that the cylinders are all of comparable shape. which would translate to healthy cylinders. Test conditions change so you can get all sorts of numbers. you just want even across the board

OTC has a good reputation and the OTC and Valley gauges -- both with a range of 0-300 psi -- are tracking closely. For example, on the ambient temperature test yesterday, OTC was 161 psi when Valley was 160 psi and OTC was 193 psi when Valley was 190 psi. The Valley is a Grade A gauge. Grade A refers to ASME standard B40.1. Out of interest i did a compression test today what do you make of these readings..the cars has 130,000 k on it (80,778 miles), m20b20 motor Cylinder 1 . 190 psi / 13.10 bar Cylinder 2 . 179 psi / 12.34 bar Cylinder 3 . 165 psi / 11.38 bar Cylinder 4 . 170 psi / 11.72 bar Cylinder 5 . 180 psi / 12.41 bar Cylinder 6 . 190 psi / 13.10 bar Today's compression test resulted in the following.

A like new 90-91 l98 should be cranking in excess of 175, depending on if the test is done on a properly warmed up engine, all plugs removed, throttle wide open and done at sea level it could well be cranking around 180-190 psi. Your engine is fine, but it is tired. What should compression psi be with 9.5:1? Approximately 130-150 psi could be expected with a 9.5:1 compression ratio. . Do you have to remove all spark plugs for a compression test? Yes, it’s necessary to remove all spark plugs when conducting a compression test to get accurate cylinder pressure readings. My '01 325i @ 230K miles measures 190+ PSI on all six. Regards, Ray L. Save Share Reply Quote Like.
