Guest HBZ81 Posted January 16, 2006 Share Posted January 16, 2006 I'm sure most of us here have heard and seen the story of the twin engine, twin turbo, awd tiburon. I know he mounted one engine in the engine bay and one in the trunk, and used automatics transmission. My question is how the heck did he sync up the trannys to put out a somewhat equal speed and how could he have rigged up the steering?

Sparky Posted January 16, 2006 Share Posted January 16, 2006 it was a front wheel drive car to begin with, so steering isnt an issue. what he did was install another FWD engine/trans in the trunk/backseat with its own shift lever. the transmission were not synched at all, it was one of the reasons it lost points in the USC competition.

Guest HBZ81 Posted January 16, 2006 Share Posted January 16, 2006 so it's traction would actually be pretty poor, worse then a FWD and not even really a type of AWD... i think... this whole twin engine idea is confusing me with the steering issue because i'm trying to design a possible twin engine car with two Ford Taurus SHO 3.4L V8 engines... or is it just turned by the front wheels and the back just "spin forward" with no steering control?

mtcookson Posted January 16, 2006 Share Posted January 16, 2006 it seemed to get pretty good traction to me since it ran a 10 second 1/4 mile on street tires. Quote Link to comment Share on other sites More sharing options...

Thumper Posted January 16, 2006 Share Posted January 16, 2006 An easy way to think of it would be a regular front wheel drive car then, and the think of a rear engine like a mr2, vw bug, most porsches, etc. All they did was combine both type of setups in one car. The car will shift at different times, and it will have 4 wheels powering it. Two from the fwd engine and two from the rear engine. Quote Link to comment Share on other sites More sharing options...
Guest HBZ81 Posted January 16, 2006 Share Posted January 16, 2006 well i guess that makes my "super car" easier to build, all i'm worried about is wet weather traction and cornering now Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted January 17, 2006 Share Posted January 17, 2006 there was a video of this lerking about b4, but i can't find it now, does anybody have the link? The burnout video Quote Link to comment Share on other sites More sharing options...
Guest HBZ81 Posted January 17, 2006 Share Posted January 17, 2006 yeah i've seen the burnout video before, but we need a link for the people who haven't Quote Link to comment Share on other sites More sharing options...
myplasticegg Posted January 17, 2006 Share Posted January 17, 2006 http://www.extremepsi.org/gallery/Dual-Engine-Shadow not the same, but the same idea, with a tight budget. (mostly spent on beer) Quote Link to comment Share on other sites More sharing options...
CruxGNZ Posted January 17, 2006 Share Posted January 17, 2006 Hey, that's at my local track! Never seen that thing. Quote Link to comment Share on other sites More sharing options...
CruxGNZ Posted January 17, 2006 Share Posted January 17, 2006 Just found out who that guy is. His name is Russ Jerome and he belongs to a group of people called Extreme PSI in southeast Wisconsin. He's on one of the local forum's here, and I didn't even know it. Here's his web page click here . "13's for $200" Quote Link to comment Share on other sites More sharing options...
myplasticegg Posted January 17, 2006 Share Posted January 17, 2006 yeah, russ is huge in the turbo dodge scene. He just sold his 16 valve turbo omni. is working on a 16 valve dakota turbo and 16 valve colt turbo. Great man, and does alot with very little.

Guest HBZ81 Posted January 19, 2006 Share Posted January 19, 2006 how would you sync up the trannys? computer program? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 20, 2006 Share Posted January 20, 2006 Don't need to, just let the torque converters make up the difference. Quote Link to comment Share on other sites More sharing options...
Guest HBZ81 Posted January 20, 2006 Share Posted January 20, 2006 that could work! but if you wanted to try to sync up, how would one do it? (i'm probably just going to go the torque convertor way) Quote Link to comment Share on other sites More sharing options...
DaleMX Posted January 21, 2006 Share Posted January 21, 2006 Rear Engine would be by throttle cable, front engine would be controlled by computer. You could use feedback from an rpm and wheel speed sensor. Quote Link to comment Share on other sites More sharing options...
AK-Z Posted January 26, 2006 Share Posted January 26, 2006 Isn't there an audi tt with a 2 engine setup. Might try to find out what they did to get it synced. Quote Link to comment Share on other sites More sharing options...
BrandonsZ Posted January 27, 2006 Share Posted January 27, 2006 If you "drive by wire" like most of the new cars are going, then you don't need to sync anything, if the two engines are similar the pedal sensor would simply send the same signal to both units, of course if they were automatic, he'd probably prefer to use paddle shifting or "stick" shifting and disable the automatic shifting because they would really offset the load if one was in 1st and the other shifted to 2nd. Of course if one engine had a problem or fell out of spec you might get some squirlly stuff going on. Also, one engine may be sharing a greater load than the other depending on it's condition, which wouldn't be "felt" if it was within a reasonably close spec. My theory, don't know if it was done or would work, but might. Let's try it with a Z. two LS1 V8's Two manual trannys. You could easily link the throttle cables to the pedal even though one would be longer than the other, they would actuate the same distance. And The shifter would only require a remote shift linkage for both trannys although the difficult part would be to fit all this under a 240z.
