Turbo CBR900 Dyno

[RocketRider]

Muahahahahahahahahahaha. When you see it you will excrete bricks...shit bricks if you will...
the big run was with the waste gate disconnected, so the turbo was cracken out all the boost it could (10psi in this case)

Does that say 205 HP at the rear wheel? Am I reading it wrong?

I can't imagine how that engine isn't flying apart.  Good work RR!

I assume you worked out the fueling problem.

Was that SPL's dyno down in Washoe Valley?

[RocketRider]

Yes that says 205 HP...AT THE WHEEL FOOS! That was with the waste gate disconnected, so the turbo was pushing 10lbs of boost. I wont be doing that often. Average was 150 with the waste gate working at 6psi. I might be able to fix the flat end if I get a boost controller. Probably will.

I dunno if it was SPL's Washoe Valley Dyno, it was his trailer one right here in Reno. Both me n brian started cracking up when we finished that third run. He didnt even hit red line because I smoked a fair amount. Unsure if it was unburnt fuel due to the high compression + boost or oil backing up from blowby due to the high compression + boost.

Did Brian offer any advise as far as fuel, given that you're boosting high compression pistons?  I find it amazing the engine hasn't blown out the crank bearings.  Goes to show how Honda over engineers stuff.

You haven't even rejetted, which blows my mind too.

But the oil blow-by is odd. I'd think it would be counter-intuitive for oil to be blowing into the cylinders, given the positive pressures going past the rings in the other direction.  If anything, it would be ring blow-by into the crankcase, forcing oil out the engine breather.  Not sure how you have the airbox configured with all that additional crankcase plumbing.

Wasnt a tune session, just dyno. I know how I can lean it out, but I'll probably just leave it.
The oil is actually at the turbo. What I bet is happening is I am getting blow by on the cylinders which pressurizes my crank case. That pressure prevents my turbos oil return from...well...returning. The oil then backs up in the turbo and starts leaking through the rotating seals.

Post more pics now that it's all done.

[RocketRider]

Done is a strong word haha. But I DO hope to make it done today. Im going to route cooling lines (been running oil only), brace the tail fairings, and paint some parts. Then I'll do a walk through with pictures n what not as part of my inspection. All in prep for Buttonwillow

It is surprisingly loud for a turbo.  Looking forward to watching it in action.
