At the rallycross this weekend at Perry Park (Bruce Perry's test-track) we all winessed the "true way" on it's first outing.

This car looks perfectly normal on the outside but hidden behind the tinted rear glass is the latest evolution of the twinni, a second V6 drivetrain! With blown out struts it didn't handle too well, and the throttle linkage really needs to be setup better but on the straight bits it really took off! Sounded great too.

That thing was scarry. I believe both engines were supercharged. The story is that it is a drag car and does 12's in the 1/4. I kept waiting for the back half to pick a different direction from the front half...

For all that work I'd hope it went better than 12's.

The best part is that 4WD twin-engine cars do Awesome burnouts if you put the front engine in forward and the rear in reverse, or visa-versa.

No doubt. a US street WRX can turn 12s.

Now I'd pay to see a video of that :9

Really? Which one?
The stock street WRX turns the quarter mile in about 14.4 seconds.
Are you referring to something else?

Twin Engines! Whaahoo!

Randy,

What a fun project. I wonder what ever happened to Tajima's twin engine Suzuki for Pikes Peak? It was great fun too!

I have long thought Twin Engines are an underdeveloped concept. People initially get caught up in worries about synchronization. But, they soon realize it doesn't matter. You just need to be able to predict and adjust the front-drive / rear-drive balance. Same considerations as any AWD, but different hardware.

I remember Go-Karts in the 50's. Heck, nobody knew how to build 'em and people were trying anything (scarry). The first twin engine Karts I saw had one 2 cycle chain saw engine independently driving each rear wheel. Most people thought you wouldn't be able to keep 'em in a straight line. But, of course, they proved stability wasn't an issue and they were FAST.

Today, with all the light weight FWD hardware I'm surprized more twin engine Hill Climb or Rally Cross cars aren't being built.

Contact Sport Compact Car and get their Ultimate Street Car Challenge video. Last year during their event they had a twin engine (both turbocharged 2.0L) Tiburon. It had 600 some-odd whp and did the quarter mile in just over 10 seconds on street tires(!). They had a good section of it doing burnouts with the front engine in reverse and the rear in drive. Very cool.
