440cc smowmobile motor. power - weight?

[mrdeadman1]

im telling you your best bet is to find a tranny from a car and have an adapter made to bolt the fly wheel to you engine you can have it go on the pto shaft just like a tav, I have personally tried 8 different ways to do this, and this is the best way to do it. I know here in kansas a toyota 5 speed trans is 120 buck at a junk yard and the fly wheel is like 15. Bike trannys don't hold up in a car no matter how small I have destroyed 6 in the rabbit

If the OP uses the said motor, how/what would be a good Idea for clutching the combo of suggested trans?

 

[machinist@large]

A big twin(non unitized) Harley trans here, is likely going to be min $3k. Need to have a oil pump and being an enclosed vehicle might need a cooling rad for it.

The big twin transmissions traditionally didn't need an oil pump (haven't checked on the current model's) but I would be willing to guess that HD engineers most likely haven't added what they never needed in the past. Don't know about current prices, though.

The bigger challenge would be the clutch/input and output shafts. On a traditional HD unit,the input shaft, with the clutch on it runs thru the center of the hollow output shaft. It's not a straight thru unit like a rear wheel drive car tranny....

 

[mckutzy]

I stand corrected.

I knew a bit but wasn't quite sure.

 

[mrdeadman1]

the way to use the car trans is to use the clutch fly wheel and pressure plate from said car if the op has the original trans from the car he posted he can use that it not the junk yard is your friend

Couple questions, then maybe a couple ideas....
First is it gonna be chain drive like a kart or are you using a auto rear end? What's your budget?

its similar to an auto rear end, drive shaft + diff like a regular car, but with a smaller, shorter wheelbase.

budget is less than $1500 i would suppose.
i plan to look around on craigslist and find some scrap metal for floors, quarterpanels and roof bits, then fibreglass the doors, trunk, hood and fenders.
Also,
it will have a quad suspension up front, modified to house 2 shocks per side, rather than 1, and the rear will be a custom fabbed axle/diff housing 1 larger shock on either side.

 

[firemanjim]

Do you have a pic of that rear end?

 

[Potato]

no, as i have yet to make it.

unless you have a better idea, i should suppose it would look something like this.
+ a special surprise too

 

[mrdeadman1]

if are wanting independent rear suspension I would grab a rear end off of a subaru with all wheel drive then shorten the cv shafts

will i still be able to make it around 600 lbs and have some kind of power with this way of doing it?

 

[mrdeadman1]

oh yeah that wouldn't really be any heavier than the one you are planning on making

 

[Potato]

how heavy is the whole rear end setup?

 

[mrdeadman1]

roughly 50 lbs sorry it took so long to reply back i kind of forgot about this post, the pumpkin it self weighs about 20 then the axles about 8 apiece

not bad, thanks

 

[Potato]

i like it.

Making a home built car legal here in the greatest state know to (any smart ) man, Texas, it has to meet bumper height requirements, have DOT certified lights,brakes,horn,windscreen,seat belt.... Everything a production car would have from factory. And it IS possible to make said "car" legal, as I've seen a vw beetle shrunk to the size of a big @$$ go kart. It still used the vw drive train and front suspension, but shortened by about 3 feet....

Texas can't be the greatest state known to man if it doesn't allow open carry.

I hope you have mad fab skills if you are only going to spend $1500 and build your own axle.

If I was dead set on using an independent rear and having a transmission, I'd look for a newer corvette transaxle. Or if you just want the independent rear end, try a unit from a mid to late 90's Thunderbird/Cougar.

If I was you, I'd forget the transmission and just run a driveshaft from the TC straight back to the Tbird diff. Or trade the sled engine for ANY 600 or larger bike engine.

i agree with you scout, about having it run from the tc to the diff but i dont agree with is any fancy/expensive/hard to piece together diff. i respect your ideas, but i want a simple "this will do it" kinda diff, and so you know, yes i know my way around sheetmetal, and bodywork.

oh, and i want front motor, rwd, birdfanatic.

Well are working to fix that...... You can open carry a rifle or shot gun for now....... Trust me, if you saw me walking down the road with the "toy" i built for my son, you'd run/move/ski-daddle away quickly...... Only thing going its missing is "full auto"....... And I'll leave it at that..... I don't want to ruffle any anti gun folks' feathers cause I built my son (11) a custom "assault rifle"......... It's nice though......
