Postby lmlmrbd » Tue Jul 05, 2011 10:30 am



i have a 78 gl 1000, i got a sidecar and thinking of trailer. The problem is the sidecar is a motivation 2 seator and top speed is 70, i have the convertion carb,and harley pipes, i also have another gl 1000, i got to thinking is there a way to bore it with bigger piston , adding double weber carb convertion with a turbo. if anyone has an idea how i can go about doing this,an getting this done , all help will be greatly appreciated

Somewhere in the back of my brain I seem to recall someone putting a supercharger on an older GL using the carb conversion and adding an accessory belt drive to the front of the engine...was supposed to "wrinkle-up" the pavement behind the bike if you goosed the throttle....

I will see what I can find in "the archives" of my old magazine collection from the 1980's....

Randakk put a supercharger on his GL1000...I think he was going to make it as a kit for a while, but then for some reason decided not to. In any case, you can see the details of the conversion on his site.

Here is a thought for you. Any good racer knows that horsepower to cubic inches that are equal is a good place to shoot for, assuming a naturally asperated engine. gl1000 are 61 ci. and around 80 hp, all things being perfect and in tune.

How much more do you really think you can get? without pushing more air and fuel down her throat?
Now the other thing you can do is make her lighter, that part is hard to do without sacrafices.

Just a thought!

Even if you were to go the turbo route, you would need twin turbos, all sorts of plumbing for oil, cooling, waste-gates. etc. and still have to modify the intake manifold(s) for the turbo additions, not to mention ground clearance issues with the turbos under the cylinders, and all sorts of exhaust modifications to accommodate the turbos... then there is the brake systems modifications to handle the additional horsepower...

Seems like you might want to reach out to Randall Washington and see if he might be able to assist you (with no liability incurred on his part) in doing his supercharger modification to your Wing... his price of 5700 dollars seems cheap compared to the time and effort required to get your wing to go faster than 70 MPH...

Just my $0.02 worth, but if you do go ahead with the project, please do post your results and any engineering data you develop... I would love to see before/after dyno results after you do your "big bore" to your 1000...

have you thought about an electric turbo kit, there available on eBay about $100 - $150 plus shipping, X2 i guess
i've been toying with this idea for an old Yamaha twin i have, TR1

keep us posted if you do anything
I'm interested

After looking at a few of those in-line "electric turbochargers" on-line, I wouldn't personally add ANYTHING to ANY ENGINE after the air filter. Those types of motors are notorious for short lifespan and "throwing solder" from their armatures when overused (as I would expect one to be in any type of installation). The solder at the very least would damage intake components and or pistons/valves/mass airflow sensors, etc.

The other types that resemble exhaust driven units might not throw solder, but the electric motors just won't last for continuous use. The motors have a duty cycle rating of less than 10%. Good for short bursts with loooong rest periods in between.

It's a cute idea, but if you want a turbocharger or supercharger, do it the old fashioned way.... shortcuts are just that.

Just my $0.02 worth again..

thanks N2PPN your $0.02 cents worth could have just saved me and others $1000s
still curious about these electric turbos but will wait until I come across something cheap and dispoable to try it on

thanks a million, or at least a $1000 or 2

im no engineer, im just very close to being a shade tree mechanic, it seems though if they can calculate the air / fuel ratio for fuel injection , that they could calculate both fuel an air injection instead of using vacume, another words as the throttle open ,an the piston goes up for compression have a port for injecting both air and fuel, seem like all u need instead of a tubo is a small electric air pump an a air tank with a montoring device, this way there would be no drag on the engine an wouldnt relie on standard atomspere pressure

How about improving aerodynamics? Seems like some major improvement could be found.

Now adding a nitrous bottle with a short burst button might help out in those "harrowing" situations where you need a quick burst of speed.... but again you will trade off lifespan of your engine for more HP at the wheel...

Just a thought... although it is a strange one....
