Thanks! Carbs are TM40s off early 2000s snowmobiles- did some tuning since posting this vid (and got it firing on all 6).
The gearbox is a custom LCR Hybrid FS5W71C unit.
It uses a very close ratio Albins gear-set (2.4 first & 1:1 fifth), 'dogleg' shift pattern, custom main-shaft, Short shifter conversion, billet forks & uses some factory 'Option' gearbox parts in it as well.
It's an amazing gearbox to use.

Great run! The gap between the rear view mirror and the far landscape really shows the down force throughout the video.
You gotta love that. The car appears so stock. Looks like you have all the systems working together well. I am curious as to which gearbox is in that car?
That looks pretty cool! What kind of carbs are those? It doesn't sound like it is running on all cylinders, though.
Terrific video! 1:39 at Laguna in a car with no aero is flat out flying...and that's with short shifting out of turn five for noise, freakin' incredible.
Great to see someone willing to pay for the best, can't imagine what that Z does for him but I bet it's sensational. It certainly looks and sounds that way
Nice to see a whole lot of Aussie know how mixing it up in California.

I've watched this video many times and it's always enjoyable. Very nice driving.
My fastest run to date. Rule book dictates a LOT of chassis mods and more safety spending at 175mph. Kept getting hassled for not dropping parachute even though one is not required until above 175. However rule book states that once car is capable of 175, the chute must be popped on any run over 150-funny technicality. Anyway, this video shows the phenomenon known as bump steer. When I applied my brakes, the nose drops, the suspension toes-out and the car wants to steer itself. Not fun at 174. Not fun at 150 either. Toe-ed in front end and it helped, but made car unstable on acceleration when nose is up. Gotta re-work geometry to stop the bump steer (or at least limit it) and reduce suspension travel, likely thru stiffer springs. Winter work.
This video didn't turn out as well as I hoped. Removed flare from this side of car to improve visibility. Still couldn't get the angle I wanted and camera kept blowing off target in spite of lots of tape and a string tether. Suspension is working. No cuts on tire at present ride height.
This video shows the effect of hitting a crack in the track parallelling the direction of travel at over 150mph. Pucker factor.
This video shows how much driving I'm doing at the top end with my current suspension setup. I'd like to be driving less.
ECTA Ohio Mile May 2015, 150mph +/- 5mphlicensing run. Recorded speed 154. 150mph is 4th gear 6000rpm. Used the re-limiter as a governor.

This is the first time I used megasquirt, so I was really skeptical that any thing was correct. Super stoked that it idled!
Megasquirt 2.0, PCB 3.0
First time turned the engine over with hope to start, Dec. 2013.
Like reelin' in a big fish!
