Maybe I missed it, but......engine size and source, axle original application, video?

It must be me that's missing something !! There's five pages on how this thing was built, and I even mentioned in my last post that this engine came from a generator !!
The only other parts that were scavenged from something else are the transmission (Polaris ATV), and the CV joints (Audi A6 )
Engine and tranny specs are on "reply #6"
CV shafts are on "reply #45"
There's a video on "reply #56"

Ya gotta read man!!

Read? Ya gotta be kidding!   Boost is too busy giving voodoo and myself a hard time to actually read.

I found it after I posted.  GX360, audi axles, short vid.  More video would be nice though. You said you were going to gear it for 30mph.  How did that work out?  Faster or slower?  Do ya have enough power for more and still be able to accelerate decent?  I'm wondering cuz I've got a 13hp honda clone sitting on my buggy with a cvt.

[hemi43]

All in all it's a pretty nice package, but it could use more power. I knew that before I started. It seems to be about 25-30 on the top end, but haven't clocked it. I definitely would not want to sacrifice any more bottom end for more speed.
We'll run it this way for a while and see what the future holds for it.
If it warrants a larger engine, then that's what will happen.
I over built everything for this very reason.

 This time I'm not kidding. Anyone know the WOT airflow CFM of that engine? If that FAN could push more air than the engine uses at WOT............................................it would actually be a cheap power adder. Worth looking into. even if it doesn't another 12V fan actually could.Some of them push quite a bit of CFM but they won't make pressure as I'm sure the one in the link won't either. However ,if the fan was to provide a "ram air "effect similar to a hood scoop then it would make more power but with the added benefit of having the ram air at all ground speeds. Hmmmmmm.....................

That's the kind of response I was looking for.  Did you mention what the buggy weighed?  An actual figure for top end would be nice also.  From my experience racing carts,  it may be going quite a bit faster or slower than it looks.

Don't get too excited Fabr.  There are lot's of ways to get more power out of these small engines.  Much better ways to spend 2 bills...
I have seen all kinds of things for the honda engines like bolting on a head from a different model and such.  In hemi's case, the water cooled option might make that difficult.  I do know for a fact that the hp of a briggs can be doubled, tripled, or more, but that won't do any good here.

[fabr]

Just keeping an open mind. The theory is good whether or not you do engine mods.

[hemi43]

I will get an acurate speed measurement in the spring when all the salt is off the road. I spent way too much time getting it all pretty to have it rust and corrode the first time out. I would say the speed is closer to 25 MPH than 30 MPH.
I tried to weigh the front and rear with a bathroom scale, but the scale needle just got pinned. An educated guess would be about 550-600 LBS
I would love to experiment with a small turbo, but then reality kicks in and it just wouldn't be worth the trouble. If I want more power, I need a more powerfull engine !!
What I will do however, is change the carburetor. Right now it has a standard small engine carb with a butterfly valve, and the bore seems to be around 15mm.
I have a Mikuni 28 mm that I plan to put on. I don't want to start modifying this engine, until I find out exactly how it performs in stock form though.
Unfortunatelly the Honda GX360 is kind of an oddball motor, and there are no aftermarket performance parts available.
Although it's under powered, it's still a blast to drive !!

I wasn't talking turbo. Just ram air.

I just had a look at the link, and right away I can't see this working. It's 900 watts !! 900 divided by 12 is about 80 amps !!
I think most of my 13 hp would be taken up by turning an alternator to develop 90+ amps ,to turn the electric motor, to pressurize the intake, to make more power,..... Do you see where I'm going with this ?? 

[fabr]

It uses a 10 amp fuse. recheck your figures.

10 amps @ 12 volts will only give you 120 watts of power.
My calculations are right !!
That's assuming that the motor is in fact 900 watts !!

I can't find where they state that the motor uses a 10 amp fuse!
I think there's a bit of B/S on their part stating that the  motor is rated at 900 watt

Hey Dan just a quick question off topic, you mentioned that you might do a section on a build of a CNC mill are you still gonna do that? Just I'm very interested...
