dual motors

Unsure why you'd want to do this, but it is an interesting concept. You would definately need to think about where and how to mount the 2nd engine... and then you'd need to somehow link them together (computer controls, perhaps) so they're both putting out the same power at the same time. Otherwise, one engine would overpower the other, making it a complete waste of time to even HAVE the second engine there.

Im on break from college now so im back in hannibal but on my pc back at college i have a Video of a duel engine setup. It was crazy fast and made some really neat looking donughts.

to awnser your question its YES. its possible and believe it or not. you dont have to run them at the same time. Fore better fuel economy just run 1. for racing run both.. With a 2 engine setup just be sure to have the throttle cords attacthed to the same gaspeddle. I dont wanna waist your time and try and explain why, but with and auto trany in both motors, you dont have to worry about powermatching from the engines.

GM did in fact make some, i saw a magazine ad for i believe the X bodies...

 

The article was titled "push me pull me"...dual motors even had a pic of both engines in...i remember seeing this concept along time ago and i would always joke wit myself saying that wit how crazy broke we were at the time, it be cool cuz if one engine breaks, fuck it, we got one more :-D

I think the best way to go about it would be to begin with a mid-engined car. A Fiero would be the least expensive, and possibly the lightest option. I say this because I think it'd be easier to put an engine into an empty hood, than it would be to put one where the back seat would be in say...a Cutlass Convertible (that'd be cool, though).

 

If you wanted to start with a front engine car, it'd be easiest to use a FWD car, otherwise you'd have to rip out the whole powertrain. Seeing as how you already have a Fiero, I think it'd be a nice little project for you...maybe a little out of your league, but worth a try.

there's a 12 second Beretta out there w/ two L67's...if I had to guess I'd say the Beretta used parts from a 6000STE w/ AWD or maybe some Fiero type setup for the L67 in the trunk?...I don't remember...it was on ClubGP at the beginning of this year or maybe sometime last year...the L67's weren't modded I don't think except one had a smaller pulley or something.

I remember hearing about a Fiero with dual engines, now that I think about it...it was on this board, do a search.

 

I think you can use a regular FWD tranny for the rear wheels, because I think that's how they did Fieros anyway.

 

This guy knows Fiero shit:

If you're actually considering doing this, he might be of some help.

a friend of my dad's built a daul V-8 chevy pickup. It had two v8s mounted side by side with a custom transmission and gearing box that linked them together. The thing wasnt too fast but it hauled more weight than anything he'd ever seen before!

 

Alot of early big rigs had inline v8s where the driveshaft would go directly through the two engines.

The concept of a dual engine car is sweet. And to see one would be even cooler. But what i cant grasp is how that could make it any faster. Wait....hmmm i think i get it now that i think about it but someone explain why it would.

I'm no mechanic or physicist, but I'll do my best...feel free to correct me, anyone.

 

First off, AWD helps the car go faster. Second off, you put twice the power to the ground because you have two engines working on seperate axles. The positive force of friction between the tires and the road happens at two different places, and since you're most likely gonna be using engines that are as identical as possible, you've got double the force.

 

Of course, you need this force to help out alot, because the weight of an extra engine is significant.[/i]

Thats kind of what i started thinking. 300hp on only 2 wheels = fast 300hp on 4 wheels = faster. Thats about all i can come up with. Ill think before i ask next time :roll:

It depends on how you divide that 300hp up. Like 93RegalGS said, the extra weight would make it slower.

 

Like, if you had two 150hp engines, you'd be slower than a two wheel drive car with one 300hp engine. One 300hp engine with AWD would be faster yet. Two medium sized 300hp engines (for a total of 600 flywheel horsepower) would be faster still, despite the weight.

there is a guy on beretta.net that got sawzall happy and did it with 2 SC 3.8s, only got a 13.2 out of it tho, one motor was stock, the other got dynoed at like 295hp and 341ft lb.

Sport Compact Car runs a yearly "Ultimate Street Car Challenge". It is going on it's 3rd installment this coming Year. The first competition included said Twin Engine Tiburon. That is one helluva car!! Also, if you check out the DSM boards, you can find links to a twin-engine Talon. It's actually not a SUPER hard thing to do, just requires a lot of fabrication.
