Twin Turbo Evo?

Anybody know of anyone trying to do a twin-turbo evo? What would that entail?

I know that's really kinda silly and all, but I was thinking about autox setups and dreaming about the FP Red setup, and realized that almost no turbo is going to spool before say 3 grand... sounds like you could really gain some ground going to tiny tt setup. Imagine pulling out of a corner at almost full power by 3.5-4k.... awesome for a short course.

Just food for thought.

FP White would be BRUTAL on a 2.3 probably hits full spool at like 1500rpm! J/K maybe 2500 though?

Im surprised that no one has built a 2.3 with a Vortech supercharger yet

Not my kind of pony, but still.

2500 seems about, right give or take, mostly take though

You will get a whole bunch of EVO 'experts' claiming that your question is totally ridicules. "Two turbos is one too many." "Look at the RX-7." "Look at the Supra."

My response to the naysayers would be, "Look at the Bimmer 135/335." Why is no one laughing at BMW?

That said, I think a better set-up idea -- with far less plumbing required -- would be a compound turbo. Basically that is a small turbo blowing into a large turbo. The best of both worlds -- very quick spool and very big HP.

Nope. They tried it. Had some tuning issues. Went back to one turbo and WON the competition.

I'm down with twin turbo, but the 135 & 335 do so well because they are inline 6's along with the cummins you posted above. I'm all for a twin turbo setup but it's incredibly difficult to do it efficiently considering the smaller displacement

A 2.3 or 2.4 would probably work a bit better though.

Cosmo (his nickname, friend/sponsored by Devo Tuning a couple years back ran a custom twin 16g setup), they ditched it after realizing it's not worth it.

Too much work to get a twin turbo setup to work properly...and the reliability would go down.

They had a guy put a supercharger on a Evo a while back and made some desent power. I think it was like mid 600's. The car has passed into a few hands though and I'm sure has had more owners since then.
