This is the wrong approachHow much hp/tq is the stock transmission capable of handling w a shift kit and super servo? As I modify, a built tranny will be on the list......
The tranny should be the 1st thing that comes out.
If it slips and fails and you have no safeties in place the motor will over rev.
Keep it at 17psi till your ready.
A stock turbo at 25+psi will lay waste to a stock 200.
I've seen them 500+left of torque at a very low rpm.
