if you say so...lol

yeah, I guess if you want it to run at a specific psi on operating temps (on the hairy edge) you have to run expensive fuel so you don't melt down.

"the hairy edge"...lol

the thing's gonna detonate anyway if your timing is advanced. the thing is how are you supposed to set one up to run at 185 and cold it's 190 if you're worried about detonation damage? and yeah, 5 psi is "substantial" if it means the difference between pump gas and 100 octane to avoid a...

I've never been able to get a good reading from a cold engine. it's always different from cold. and when you're running borderline pump gas compression, you can't afford to make a mistake because you're too close to the line to. if I set my engine up to run at 185 compression cold, I'm lookin...

killer grab-bag motor...lol

right, but if you want a "true" reading of engine compression, let it reach operating temps before you test it. just sayin'. :dunno:

that's why you always bring an engine up to operating temps before doing a compression test.

you can make your own pre-filters with monofilament screen printing cloth and silicone spray surface lubricant.

we can start a "get harrison on the water" fund. I tried...lol :P

It would expensive to get titanium studs and girdle bolts made, but you wouldn't have to worry about them breaking anymore...lol

good luck finding any 518. MrSki used it all on one set of 550 cases. if you're snapping girdle bolts left and right, something else is going on. they shouldn't be snapping like that unless they're a poor grade of steel. you gotta put some serious pressure on a stainless steel girdle bolt to...

laserpope it. regards.

girdle it.

I think a shirt would look cool with just a small graphic of "X-h20.com" about 3 1/2" X 7" right in the center of the front. :dunno:

post some possible graphics. lets vote on it. : ) or lets have a T-shirt graphics design contest.

what happened to the "realtime posts" link?

lol

fox, you should get some race gas domes and race that hybrid. :)

scorn is right about using the 750 electrics and it having a better timing curve, and also you would be better off using them with that setup for a rev limiter. 650 electrics don't have one, that's also what's bad about using a 650 voltage regulator in a 440/550 e-box on conversion skis. when...
