That is just what you needed!!!

I want to drive it when you get it done.

As a matter of fact, call me and I'll come help you build it.

I suppose that depends on what you think it is. To me it looks like a big pile of Pick Up Sticks at the moment.

If you're thinking that it's a Miata that has been completely stripped, and had a tube-frame built around what was no longer there, you may be correct in what you think it is...

But probably not. Long live Berzerkely, in whatever form it may return... In some form... Or another....

I hope your plans for that are similar to plans I was hatching.

I'd like to do some hillclimbs and for that you need a good bit of HP. I am not a fan of front wheel drive, either.

I thought it was the most feared GRM project car ever, and it appears I may have been correct.

It did leave a lot of scared people in its wake. I hope to tame the beast.

I think that diff would be a bit weak for what I have in mind.

That needs a big bike engine in the back. I mean HUGE bike engine, nothing south of a liter and 150hp.

It needs to be a compact high revving powerplant and I have not written off using a late 4 stroke snowmobile engine although a liter sportbike engine is currently leading the parade, I lean toward the R1 Yamaha due to its oil pan configuration. SeaDoo's supercharged Rotax engine is a very outside possibility but there's a lot of problems with a transmission.

At one point, a rotary turned sideways with a snowmobile type torque converter was under consideration. Yes, I has dain bramage. That would be big $$$ because AFAIK no one has ever tried that, meaning everything would have to be custom made.

I'm not overly enthusiastic about a turbocharged setup due to turbo lag. I can just see myself wailing on the throttle in a turn at a hillclimb, then have my old man reflexes trying to catch the thing when the turbo decides to spool up.

A low boost setup on a high comp bike engine won't be laggy with a correctly sized turbo.A litre bike engine geared down to hill climb speeds won't have any trouble pushing that up a hill briskly even without the snail.

You know, I know a guy with a mill and a lathe...

Steal the chain and pulleys out of a Ford CVT...

Hmmm...

Or maybe out of a Nissan.

That ought to handle the HP and with the right case around it it wouldn't eat belts like a Comet setup does.

Awesome. I am delighted that the Berzerekely has gone to someone who will continue to create stories with it and tell them on the forum...

Looking forward to the build!

You do realize 1) those are both the same JATCO transmission 2) it's electronically controlled via PWM solenoids 3) the fluid is like $65-90/gallon depending on where you find it 4) it has a pretty high failure rate? I'm thinking someone else will have to R&D that.

Gates Polychain can be had tough enough to handle the HP but the belt is damn near $300 before I even touch custom sprockets. There's a proprietary tooth shape which gives it the HP capability meaning they would have to make the sprockets and I see my budget going up in smoke quickly.

I keep leaning toward a duplex chain. Martin Gear makes tandem sprockets, I am thinking get a blank, have it broached to fit the output on the gearbox, then machine the ring gear flange on the diff so I can bolt a spocket on either side. Not really as easy as I make it sound, but probably a LOT easier/cheaper than the CVT.

The poly chain might not like standing starts with slicks,f500 guys run poly for road race but switch to chain for autox.

What about using a bike driveshaft setup to a small diff like they use on 4x4 ATVs?
