Whats your compression?

Even engines that are built for high rpm like 2 strokes, holding and hearing any engine at wot for a long period of time makes me cringe lol.

you have dual cooling right?
Not sure at the moment being that I've only run 1.5 tanks of gas through it since the rebuild. After the rebuild, my mechanic said it was just shy of 200 psi. He said once she breaks in it should be around 175-180 psi.
Yes. Just set it up for dual cooling after the rebuild.

You using race fuel to break it in? 200psi should at least be a mix of race fuel and 92, if not then yeah don't hold it wide open very long.
Who said "can't"? I simply stated he said he doesn't recommend WOT of more than 6 - 10 seconds at a pop. I'm pretty confident in his ability to build a great motor. I've seen his work and his carbon fiber blaster is a monster.
That's why I came on here to see what other people thought. I don't really run WOT for long periods of time, but I used to run WOT for several minutes at a time prior to the rebuild. The pistons that came out of the ski were pretty scarred up. He stated this was due to overheating and the fact that they were older Wiseco pistons. He said the Pro-X pistons would be much more durable.
No race fuel, just the highest pump gas I can find, which is 93 octane.

normally the compression raises as the motor breaks in, about the number of tanks you're at now.
At 200 psi and pump fuel, I wouldn't be running WOT, either.

I run 200 psi on my own motor, and I use a 3:2 mix of 100LL avgas/92 octane pump gas. I also use a programmable ignition to retard timing in the upper RPM's.
My boat is a lot lighter than a Blaster, thereby imposing less load on the motor.
And I still don't run WOT for more than 10 seconds (it's probably more me being chicken rather than the motor not being capable).
IMO, it's amazing that your topend survived as long as it did.

Thats an easy question to answer...till it blows the crank bearings!
I agree with ryan as long as it tuned correctly then you shouldnt have a problem Problems come when people hold them WFO with no load on the motor or no cooling water. Running just a hair rich will never hurt , in fact might save you in the long run. Just my opinion.
