I'm still sleepy in the morning so I don't type as much, but twin charging will give you the low end response before the turbos kick in. Of course, this setup is a bit more complicated.

So one can setup a Stillen super charger and STS rear mount turbo setup. It was done on the 350Z.

But what about when VTEC kicks in, yo?

The reason I asked if that was a smart*** comment is because I was the one who twin-charged my 350..lol.. Well I used a PL kit instead of STS.

The guy with the STS twin charged just sold his to a guy in England. That car never made it to the states.

Oh snapz?! That's sick man. How about electric turbochargers?

If I were you, I would start looking for dyno's showing when boost starts ramping up and what you find acceptable.

This isn't exactly true. It is highly dependent on setup. Put a couple small quick spooling turbos on a z34 and tune for low end and suspect you would find a car with very little lag but perhaps more limited top end from bigger turbos. Certainly less lag than say a centrifical supercharger running 8psi pulley. Now put a higher psi pulley on your car or put a roots type supercharger on and supercharger may have an advantage to two small turbos.

On the other hand, a flatter torque curve is generally a good thing. If you're going for drivability for racing, and staying under a certain HP number for points on your dyno inspection, going for smaller turbos (or smaller SC) tuned for the low end might be your best bet. Give you a wide usable power band and don't even try to go for a tall peak out at the high RPMs.

Shamu, I'm referring to pedal delay, not boost lag. Definitely agree with what you are saying though.
