RZ350 Land Speed Build

 Built this in 2013. Set a daily record, headed back to Bonneville to claim it back. Thought you'd enjoy some pics.

That's Tits! Glad to see you're still getting to tinker Brandon.

It's been a fun and challenging build. 350cc serval on methanol at 15psi boost. Biggest challenges were building a return type fuel system for the blow through carbs and designing an oiling system for the turbo.

Turbos don't work!

Lol Green! This would make a really fun dune engine! When it hits at 8200 rpm and jumps from about 5psi to 15psi you better hang on! Would love to try this bike out with some more reasonable gearing. 2.68 primaries and 19/32 sprockets makes for a sluggish 65mph first gear lol.

No records this year, but was a fun and learning experience.  Smoked the left piston 1.25 miles in when it sucked the left bowl dry. Going to make some one off custom upgrades to the fuel system to keep this thing fueled. Guess I will update in a couple of years when we can get back on the salt.

Do you have it setup like a pump around, similar to what you see on a kart? Turbos don't work, I'd never own one!

Well, this one seems to work incredibly well as long as the bowls have fuel. Not a pump around. Using an efi pump with 1:1 rise regulator and return to tank. Going to do some magic to add fuel under boost.

And you talk like I dont know you've had a good running turbo bike lol.

Oh yes... fighting them turbo fuel blues. I remember those days! What carbs are you running? You fuel system sounds really similar to mine.

Running 32mm TM Mikuni setup for blow through. Good 1.25 miles lol

I assume your carb vents are connected to the plenum. You think boost pressure could hold the needle closed under full boost?

[Wildcardracing]

No, with the rise ratio regulator it gets 21psi fuel pressure at 15 psi boost. I am quite positive the velocity increase through the carb at 10k and 15psi is outrunning the volume capacity of the needle/seat
