Would that thing fit?

[slomove]

Just curious...

[scannon]

I''l bet the exhaust note will be sweeeet.

[Spaz]

I have been thinking the same thing.

 

One thing that might cause a problems is where the drive shaft comes off the motor to one side and not out the middle.

[David C]

I had a CBX & posted a while ago that I thought it would sound aweome in a seven, but with an air-cooled engine that would be a wee bit of a problem to cool the motor.

 

Now this is much better, although a bit lower redline IIRC.

 

The CBX motor was around 24 inches wide and this is supposed to be 4 inches narrower, or around 20 inches. Ballparking it I'd say the output shaft is 1/3 over so the engine would be about 2/3rds offset to the passenger side or a tad over a foot. Sounds feasible. Plus the weight distribution would be offset to compensate for a solo driver.

 

Intake tract & throttle body location might need to change for height.

 

Did not see any mention of a reverse but if its first debut would be in a tourer, maybe it might have one ala the Goldwing.

Am I the only one that has considered the electronics? The same company that invented I-drive and the 850. I believe its motorcycles also have anti-lock brakes. I think this would be a terrible engine and I built my seven from the ground up. I like the CBX engine, even being air-cooled. I could deal with the cooling issues as part of sorting out of the car. I would rather cast, machine and assemble my own engine than deal with a newer sophisticated Beemer engine. Maybe a Mega-Squirting genius might be able to build a system to run it and then tune it. The car is simple, keep the engine simple.

Have two 850's 24 cylinders, 12 speeds, no waiting. :auto: I don't know what you are talking about. They are simple cars really. Just take all the hydraulics & electronics in a 747 and cram them into 3000 lb car to make it a 4000+ lb car. The computers make vista running on a 286 look good. Case in point: the windows raise and drop out of the rubber channel to allow the door to open. Some anti-electrons must have gotten into my system and the headlights now jump up and down in time with the windows.

 

But it does look like a sweet motor & electrons be damned I'd love to hear it sing at 9 grand.

[David C]

Already has a dry-sump built in with integrated oil tank.

drool drool

I think that the new Yamaha V Max engine would be a sweet BEC choice. It is 198hp right out of the box, V4 design and pretty good torque for a bike engine.

[David C]

Ah but will it's song at 9 grand give you goose bumps?

 

Loved the sound of my old CBX inline 6 with Kerker header.

 

Being oriented towards a sport touring bike and coming from BMW though the stock sound will likely be muted.

I wonder if you could put this engine across the engine bay and more or less have the shaft drive output face back to directly connect to the drive shaft. This might work better for a right hand drive car where you can sacrifice a bit of the left footwell.

[David C]

I think it would work better for a lefty.

 

The output shaft looks to be about 1/3 of the way over from the left side of the engine with the other 2/3rds right of car centerline balancing out the driver's weight. Footwell shouldn't be less but rather more as the whole shebang would be in front of the firewal and there wouldn't be a bellhousing or tranny intruding on the footwells.

 

I still wonder if it will have a reverse like the Goldwing. That would solve one headach with bike-engined sevens. Somehow I kind of doubt it as the Germans would consider it wussy on a relatively light sport tourer instead of the two-wheeled Winnebago's some drive around.

 

Technically the hardest part would be rationalizing to my wife why I am disassembling a brand new $25 - $30,000 BMW motorcycle. After that, electronics re-engineering, design & fabrication would be a cinch. :jester:
