that's bvadass....is it only in the engine bay or do they have one in the rear (video diary wasnt loading for me)

still love the APR R32 launch at the track and the AudiTT with two engines (one infront and one in rear) the best....that thing was sick.

 

I followed this forever and then dropped out while it stalled.

How did the owner end up accomplishing AWD drive for the 2 engines?

 

I would love to drive it... but I am in no way jealous of the builders. That would have been a complete nightmare.

Cruz, there's another VR6 in the hatch.

not really awd, more like 4wd. engine in the front driving the front and engine in the rear, driving the rear.

 

Theres one in the E.bay and one in the rear. I think the AWD was achieved by a custom throttle link? Thats how they done the Twin engined Vauxhall Nova.

 

I remember there was an older GTI golf here in Toronto that had a rear mounted vr6 in it. Cool little bastard of a car. This Lupo kicks the crap out of it though

 

i know i have asked this before, but whatever happened to the twin engined focus

 

Yup, two separate engines. They even start the engines separately. They call it a W12, but it isn't (as they don't share a common crankshaft). Cool idea, looks pretty fast in a straight line, but I really wonder how predictable it would be on a road course. There is a common clutch, throttle, and gear selector. The clutch setup was a hack job, but most of the other stuff looked pretty decent. I like the Lupo, especially with way more tire, wheel, and power than it was ever destined to have

 

The same thing has been done with a Tiburon. V6s front and back driving each set of wheels.

If you are talking about the Super Street Tibby, that was 2 4cyl Turbocharged engines.

Ouch so if there's flex or stretch in the throttle cable to one engine or the other, the wheel speeds will be off? That sounds super tricky to calibrate / drive.

 

^^^ I cant remember how they done it... something mental anyways lol. Thats the best way, and easiest way to describe it lol.

That is freaking amazing... what time and money these peeps must have on their hand!

 

Drive by wire and automatic transmissions would make all this much easier. A couple turbo Duratecs in a Focus would be pretty cool. Nate

im almost positive (a little fuzzy) someone did do a double-Zetec focus...maybe it was just a rear-engine focus:dunno:

I'd bet they use hydraulics instead. Stripped car gives you the ability to run a long straight... and just use the same amount of fluid in each (other one just having a longer piston. The pedals attached to each other, means they'd share the resistance.

I wonder if he could also rig up some sort of mechanical speed control or feedback system to lock the speeds of the front and back wheels to each other...

 

With a lot more resources... I'm sure it's possible.

It is easy to have the throttle position be identical at each engine. In case you didn't know, your engine moves a lot, but that doesn't mean your throttle changes position. And wheel speed isn't a function of throttle position. My throttle has been WFO at 0 mph, and 108 mph.

And as long as the tires aren't skidding and are the same diameter, the wheel speeds won't be different.

 

Would be sweet to have the computers sync together during starting. Wait till both engines have the same crank position and then have the standalone management take over firing each matching cylinder at exactly the same time.... same amount of fuel...

 

And wheel speed isn't a function of throttle position.

It isn't, but if one engine is at higher RPM than the other (and all the gear ratios and wheel diameters are the same to both the front and back sets), then one or the other throttle position should be adjusted to try to bring the two engines in line.

And if the front and rear wheels RPMs were matched (at an instantaneus point in time), but the throttle position was much higher to one engine than the other, wouldn't the power bias be really really tricky to deal with as you accelerated?
