So I am saying the guarantee means nothing to me.

Assuming 825 at the flywheel? What size twins are you running? Any headwork done?

824.x at the wheel, 946.x at the crank. Just JWT C2 exhaust cams listed in build. Don't need any headwork. Just little twins, Zonarotor turbo's equivalent to GT3076's.

Well I guess I'm gonna find out if a bigger combustion chamber does much. Haven't CC'd the heads yet, but I unshrouded the valves pretty good. I have time right now and did it myself, I would have never of pay for port work. I figured I needed all the help I can getting this thing to spool up in the rear.

Of course plan B(n20) will light it up real fast...lol. Then watch the firework show producing a giant cloud of tranny fluid and coolant, lol. Spooling it will be my last problem, for sure...

If you wait until 6:00min. in you will found out why our cylinder walls get torched when the headgasket lets go at full boost.

That's called steam cutting. Seen it a lot it in steam turbines that had a leak on the high pressure side. Looks like someone took a cutting torch to it.

In this case. When the head gasket goes. The coolant becomes steam from the flame in the cylinder.

I am just about positive the one cylinder I am down the cylinder wall has been torched straight to the coolant. LOL, that is why I haven't been all fired up to diagnose it any. It's a waste of time.

Spooler... Sorry to hear about your build going south. I just came across this today and was always hopeful yours was still running strong. We are still working on mine but taking our time. Just need to keep pushing the platform until we find a solution
