Hard compression when cold

[Vector LTX GT 08]

If it's not one sled then it's another ! I think you have like 16k on this sled and it still does over 100MPH on the lake ! How many other brands after not touching the motor will do this and still put that smile on your face !!

I know what you mean. The best my sled did was 117 on the speedo. I just feel bad, at how I have been running the motor with gas mixed in the motor oil. But I think I am getting things narrowed down. And prob going to need another fuel pump at some point.

Just like what maim said, that is what the cause of the hard compression. I believe that one of the cylinders where full of gas making it seize up. Why that happened, as some of you guys may know I had 2 leaking fuel pumps, so that was the cause of the gas getting into the cylinder. Thanks again for the help guys, I also put brand new motor oil in it to, as it was due to be changed.
