Thread: motor compression

I found this motor on ebay and was a little shocked when I had seen 180 psi compression. I thought the msx 150 had around 140 psi. I thought 180 psi with a turbo would be a little much.

180psi is inaccurate for turbocharged Weber engine. The compression ratio for all turbocharged Weber engines is 9.0:1 and the normal compression reading is 140psi +-5psi.
The naturally aspirated Weber engine have a compression ratio of 11.0:1 and their normal compression reading is 165psi +-5psi. These have never been used in any Polaris PWC's.
