I guess you are not familiar with the GN or GNX or the '89 TTA, they all were single Turbos on a V6 right from Detroit. There was one american 4 banger that was also a single turbo, the SVO Mustang.
Speaking of the GN's, most tracks generally have a GN vs. Mustang day/night, and guess what car generally wins 75% or more of the time?
Yea i didn't say but i was thinking 4 cylinder turbos...your absolutely right. But with v6's you already have more torque than 4 cylinder engines do for the most part so there is less of a need for twin turbo early spooling when designing a fun to drive vehicle...
mogs, he is pretty darn accurate. Most 4 bangers I have seen are singles, not twins. The only real small engine that I had seen that has done rather well with twins is the RX7 TT.
Even the Supra TT people change over to singles if they are serious about racing.
Yeah aftermarket kits are singles and newer car have been singles on 4 bangers because of better turbos are available. The SVO Cobra wasn't all that quick with stock boost and had a tiny ass turbo get that car to go anywhere. I was also referring to other turbo cars, not 4 cylinders. You wont find a twin set up on a 4 cylinder from the factory anyways. V6s(Japanese) and rotaries will have twins. Other than the lack of torque from the Rotary motor, twin turbos is selling point.
Singles are better on inline motors while Twins are better on V8 shaped or other non inline motors.
I guess when Kirky said that, I understood he was referring to the twin turbo stock cars that came out in the early and mid 90s.
