Evadman's New Project: 103 HP 6 Cyl Go cart.

[Siddhartha]

Was your brother hurt in the crash of your first kart?

 

[Jzero]

I'm concerned about a go kart that has more cylinders and nearly as much HP as my Civic 😀

 

[thomsbrain]

that thing is going to be awesome. definetly keep us posted. 🙂

 

[RossMAN]

Don't forget to slap on some AMD decals, should add a few HP!

this sounds like one of the coolest projects ever, wish i could do this someday.....just wait

#1 It's MUCH heavier
#2 Technically, OIL cooled, but I'll still concede that single point.
#3 It's a COLLECTIBLE!!
#4 still only 105hp - no more than a late model 600cc I-4
#5 you could sell the bike (whole) and buy an even COOLER motor with all the $$$ you make! Find a wrecked Hayabusa...how about 165 hp??
:evil:

**** Update:
Seat and 5 point arrived! Yay! A piece of trim is broken on the seat adjuster so I have to call Jegs. They shipped it fully assembled which weirded me out. I thought I was gonna assemble it, or at least have to attach the back to the front. It was funny, you could tell exactly what was in the box because of the shape. It looked like a chair wrapped in cardboard 😛
Seat & harness
Width of harness compaired to my hand for youz that have not seen the size of a harness

Ordered my Hydralic pipe bender and dies 🙂

And returned them becaus eI am stupid, and ordered a PIPE bender, not tubing.

However, now have the stuff I need to start building the frame. I plan on starting when I get home from vacation @ Vegas.

:Q that is all I have to say about that

 

[PowerMacG5]

I call first ride after Evadman.

 

[guapo337]

that will FLY!

 

[Hayabusa Rider]

So when will this thing be up and running?

 

[Kenazo]

I had something like that. My dad bought most of it at an auction sale once. It had a 4 cylinder 750 Kawasaki in it. Was a highly modified Honda Odyssey (the go-cart, not the minivan) Chasis. It flew!

Can't see the pics, but I imagine they're for your 914? Nice 😉

Anyways, can I make a few suggestions:

#1) If you plan on going 160+ in this thing (don't think it'll make it that high IMHO, Maybe 140ish, but whatever), put some brakes in the front. At low speeds the rear brakes will do just fine in stopping the car....but have you ever even tried to stop a bicycle in grass from like 20mph with just the rear brakes? Especially when you combine your heavy rear suspension (unsprung motor) and all unstableness back there, it could get ugly quick. I'm not sure of the easiest way to implement them...but you might want to explore this.

#2) Having the engine unsprung will really help make this much easier to build, but that will add a lot of unsprung weight. The unsprung weight makes more for the shocks/springs to settle down after each bump, so expect a lot of wheel hop in the rear. Shouldn't really be a problem, until you get to real high speeds.

Whatever you do this looks like a real fun project. Keep us updated with lots of pics 🙂. Nice to see you got a good saftey harness for it too!

I got a nice rotax in my garage for exactly this purpose.

Too bad they're so fscking expensive.

Yep. This one came off a Bombardier Olympique snowmobile that sat for ten years. It runs, but needs a carb rebuild.

Will engine cooling will be a problem?

He might need to make some sheetmetal to direct air..

The cylinders right behind the seat might get hot.

I know. I really want to do front brakes as well. I am thinking of ways to do this. I may end up using a front spindle from the smallest car I can find, and using the disks that come with it. But I am not sure. I plan on the bike being all hydralic, so it will be fun. I want the front to be fully independant, so a beam axle with a disk on it is out.

#2) Having the engine unsprung will really help make this much easier to build, but that will add a lot of unsprung weight. The unsprung weight makes more for the shocks/springs to settle down after each bump, so expect a lot of wheel hop in the rear. Shouldn't really be a problem, until you get to real high speeds.

Remember, shifter carts hit 120+ speeds. And all without a suspension. I am adding the suspension because I KNOW I will be using it on dirt/grass at some time or another. The problem is this adds unwanted suspension height, which means the COG is higher, which means I have to make it wider and longer. I plan on fitting it in a truck bed so I want to keep it under 96" long, and 54" wide from wheel to wheel. That is also the reason the engine is unspring, so the axle can be as close as possable, and get the most wheel travel. But I have ideas for a fully independant rear suspension as well. Don't get me started 🙂

By Spring. If I get it close enough to a drivavble state, expect snow pictures. I already built a 60% complete mockup using conduit from Home Depot (which I returned after the mockup) so I could figure out how much tubing I need. (80' of .093 and 8' of .120 all 1 1/2" DOM tubing. The .120 is for the roll bar hoop over my head.) I want to be able to land upside down from a minimum of 10' up with no damage to my head. It will take some engineering to get the cage to give enough so energy is absorbed, but not so much that I get a bar in the head.

I plan on either ducting air from in front of me to the engine, or using a electric radiator fan right behind my seat blowing on the engine.
