2012 rxtx 80psi of compression but runs fine

[Sharkdiver1125]

I have a 2012 rxtx 260 I bought brand new, now has 140hrs. I've had minor issues with the ski but nothing serious. Although It has ingested loads of salt water, 10 hours run time on a badly leaking intercooler and also having water being sucked through holes in a kanaflex intake. I have some minor mods, no valve train or interval work just a 8350 vtech reflash and a et137+4 supercharger wheel. All 3 cylinders Are at exaxtly 80 psi of compression and I hAve double checked the gauge on other skis and they are where they should be. All the threads I read people with compression under 100psi are freaking out and replacing motors. My ski is running strong as ever (78.7 GPS at 8300rpm, 13psi boost, 12.0 afr). Anybody have any opinions on this?

Wow that's a little low but if it runs fine and doesn't burn oil just ride it!!!

Compression numbers used to make me crazy years ago . These days I look to make sure they are even across the board.

Was this compression test done cold?

Yeah mines is doing that too. Started off with 130 psi when I had my motor rebuilt with CP pistons. Now it is at 115 all across the board. I think it is my timing since I do not have the rotax racing chain tensioner. My head has been decked twice and block once.

No it doesn't burn any more oil than normal, but the compression is the same hot and cold
