I keep it simple by having but one point. "Show him the tail lights". And in the number of races I've been involved in, track or no track, FWD or not, I've held my own against AWD and RWD cars.

That and aren't you gonna get massive torque steer?

The turbine has to be properly sized according to the actual engine itself. My old turbo was a 16G as mentioned. On such a small turbine the spool was damn near instantaneous and full boost was realized around 2600rpms. Small turbo on a 2.4L engine produced a peaky response. My torque curve was shaped like "^". All the peak torque real low and it was like slamming your ass in the seat. That was great on the street. By the time the other guy was ready, I was already gone. The trade off on that turbo was the top end was stellar. You took off early (even though my top end was stronger than say an Evo 9 MR), it was not as strong in terms of say another tC with a little larger turbine.
That kind of turbo would be troublesome on an AutoX course or a track as on corner exit or in low gears you would do burn outs. At 12lbs of boost even on a 20G (upgraded from a 16), I could roll into 3rd gear at 40 mph and simply light up the tires until 70mph. It's to peaky for anything other than the drag strip and street races.
For a road course you want a less "violent" turbine with a flat torque curve and smooth power climb instead of a smaller turbo that's more like "BAM BOOST". The larger turbo may feel slower because of the not so violent smooth climb, but that's an illusion. The top end will be greater but your trade off is a slower spool. Here is where you decide if you are satisfied with a Journal turbo or do you want to shell out a little extra for Ball Bearing. BB is a beautiful thing because it will give you back that quick spool, still a smooth power curve and still have a greater top end than a smaller turbo.
My new turbo setup is a Dual BB GT3076R.
