The Eccosse Ti is back for a tune up. Needs a little more power in the midrange. Only makes 200 horse at 5600 rpm. Lets gear up the blower a bit more. 450 lbs dry weight. All titanium chassis. Carbon fiber everything else. Looking forward to the test ride tomorrow. Jim :D

sure is a funny looking Norton :roll: how big is the motor? I looked them a few years ago at Dayton and will admit they have some neat stuff.
 
Is the blower a belt driven turbine type (ala Drouin style)?

I see what appaers to be a red rubber hose going to an intercooler up front. Is that the blower?

I just checked the price for one of these bikes - Yikes! Got good shop insurance?
 
The blower is at the left front connected to that mess of pulleys driving it. It is a turbine style with a roller element drive to speed things up. It is a 2150 cc motor .
I have put quite a few miles on the thing during the initial build. It's impressive although the riding position does not go along with the speed potential very well. It feels just like a giant dirt bike with balls.
The next one will be twin turbo. Jim
 
Looks like fun. Would like to try an ergo-friendly version of it...

With 2.15 liters displacement I doubt it would take much boost the get the torque/power. What's the max boost and where at?

Makes me want to go out in the office and start drafting up a business plan and design for a new motorcycle for the market. Best of times/worst of times to start something like this.
 
Without a pilot this beast calc's out with ~2.3 lb per hp and a calc'd projected ~190 lb shaft ft torque, it should have ~2.4 lb mass per lb ft torque.
When wet and with pilot, should have ~1 hp per 3 lb mass and bit over 1 lb ft crank torque per lb mass. If traction enough should be able to do a 9 sec flat 1/4m et at over 150 mph.

Your calculations are off.
 
That is some "Spaceage" looking gear.
Fantastic Jim.
More info for those of us on the other side of the world please.

AC,
The chassis was designed by Don Atchinson of Ecosse Motor Works in Denver Co. The engine is an all billet twin cam design from Enginuity and S&S. It uses a 6 speed aftermarket trans but I do not recall the maker. The bike was brought to me as a rolling chassis with the engine installed 5 years ago and I designed and installed the fuel injection and supercharger system along with the related plumbing and wiring . I worked with the bike for a couple months dialing it in and working out the glitches.
It was then delivered to a customer who rode it on occasion until recently when some health problems made him give it up. Now it is back in Denver getting refreshed and Don brought it back to me so I could make it from something outrageous into something scary fast. I think we succeeded. My hands are still shaking.
Now it is headed off to replace the Titanium exhaust system with an inconel system. I will be looking to see it back in about a week for a final touch-up on the tune and then it is off to a new owner in Russia. Jim

With the new supercharger drive I am seeing about 1.7 atmospheres at the rev limiter setting of 5700 RPM for 200 HP at the rear wheel. It is scary on the dyno. It left me wishing I had a remote control so I could run it from the next room.

Went they about $65k or so new? I'm sure this one is well north of that.

275,000 - but you get a free watch with a matching serial number.

The 65,000 dollar job was the base with a steel frame and a carb with no blower. Looked similar though.

Here is Brad *****'s mechanic test riding Brad's base model several years ago. Ouch.

Thanks for the link. I had not seen that one before. Jim

Just like a picture, wrap the YouTube URL with the <video> tags to embed it. Jerry even provided a button.

And, um, what was that guy trying to do?
