and like 50 lb ft of torque

torque > hp, good powerband > peak power

Bike motors have been thought of many times.

The problem with motorcycle engines in cars is that the transmission is built onto the block and has terrible gear ratios for a car.

Out of the box is the crazy British motor using two Busa motors fused together at the crank to make a V8. Yes, they had to do some funky stuff because the exhaust and intake ports didn't face the same direction if they're turned the same direction... in other words one of them has to have cylinder 1 where cylinder 4 is. I'll see if I can find a pic. I think it was in popular mechanics a couple of years back.

^ You da man!

EDIT: ENGINE DRY WIEGHT 194 lbs + TRANSMISSION DRY WIEGHT 103 lbs = TOTAL DRY WIEGHT OF 297 lbs!

You want an extreme swap? Do it!



They have sound clips too... that has to be the most obnoxiously wonderfull sound I've ever heard!

Dyno...



Smooth!

My calculator was working right too. My fingers, on the otherhand (Oh! How punny!), were not.

OK, out of the box. Get your hands on some sort of small compact jet turbine engine, like what would be used in a helicopter. Hook the output shaft to a big electric generator. Connect the output of the electric generator to 4 hub motors in the wheels.

Budget, let's call it one mil.

What'd be the power output?And why couldn't you just hook the output shaft into a custom transmission and save a bunch of power lost from converting the mechanical energy to electric, and back again?

In theory, it should be more efficient, since electric motors and generators are much more efficient than mechanical means (ALOT fewer moving parts). Plus you get AWD, electric motors accelerate better, (they get max torque at 0 RPM). Plus with power independently transferred to each wheel, you can do some crazy stuff, like 0 point turning.

I have no idea what the power output would be, it's just a crazy Buck Rodgers sort of idea. I heard the army is experimenting with such a system for a new Humvee like vehicle. The purpose of such is that you can do zero-point turns, and can go as fast in reverse as forward, making it much better in roadblock ambushes.

I just thought you'd raise your losses to heat, the electric generator isn't very effiecent, and even though the the actual motors are nice, you'll losing a lot from the conversions. Curse that entropy, because it would be pretty cool.

Hmm, this thread is starting to stray a bit...

Actually, a stock 'busa puts down 100 lb. ft. of torque. I've seen turbo Busa's put down closer to 300 lb. ft. of torque.

I know that many car companies are playing with hub motors, like this one:http://www.automobilemag.com/a...equel/

Also, thi is an army diesel electric prototype that uses hub motorshttp://www.designnews.com/article/CA513599.html

2jz is a common swap......not as common as an sr20 or a ca, but nonetheless common.

i know this may be late on this thread, but how about posting th sound clips from that motor, im guessing its a formula 1 engine....i was at a bachelor party in las vegas, or as i like to call it 'a p3nis funeral' lol, there was a BAD R34 rollin down the strip friday nite with a couple of silvias behind it, but anyways, motor swap wise, how about a World of Outlaws engine? its feasable for 10k, weigh in is what id be worried about, but those things are all aluminum, run about 10k rpm, and make about 900ish at the wheels, 400 on the inside tire and 500 at the big outside one.....haha jk. but since i live in the midwest theres lots of racing teams about to get rid of their engines...so i may be able to find one relatively cheap, and they rev FAST, so itd actually be prety sick sounding. anyways, too tired to type anymore. weekend was too long.

diesel engines on trains are actually diesel electrics, which as you mention with torque is useful to get something as heavy as a train moving...the diesels these days make about 6000hp and around 200,000 lb/ft of torque

but as far as the heat goes, if you ever look on top of the engine as it goes under you when youre on a bridge or something, look towards the rear and you can see the 3 or 4 48 inch fans and like a 15 foot long radiator that cools the electrical system

yes im going off on the topic but i saw this, and being something ive thought about i wanted to say something
