Roughly how fast do the 4 cylinders hit 0 to 50 that are out there racing?

I do not know,
but if no one on MSTRC can answer you, there are some really good forums on FWD 4 cyl. racing.

Spartan has some very smart FWd 4cyl. racers and will help if you post your ?.

also 4m.net has a good tech forum for FWD and RWD 4 cyl. oval track cars.
