While a 91 is capable of running 7's in a racecar that has a maximized combination-i don't see it happening in a 3500 lb street car.The margin for error is too small.While i agree that most people over turbo engines-it is much easier for a novice to err to the larger side.

Shawn, what do you turbo do you suggest?
There is no limit to turbo size, my worry is not being able to spool it off the line with a 106. That's why is was thinking of going twins, although I would rather have a single.

If you want something that will spool well and make 1300+rwhp simply go with a GT-98 from Garrett. We have customer's easily running 4.8's@150+ with them. The GT55 turbine (which the pro-mod also uses) are a touch on the small side from the backpressure #'s we are getting on customer setups if you plan to go hard on the turbo.

Is the GT-98 the thumper unit?

gear ratio is dictated by engine rpm and tire size.
