hey guys I have been thinking about my turboed n/a project lately and have become curious abotu what my redline would/shoudl be. I know the s5's had a 8k redline, and the s4's had a 7k. Id be using a s5 n/a block with s4 tii manifolds and turbo. i know with a standalone i can make my redline wherever I want it almost, but at what point would I start/stop making power. Oh, and I have stock ports.

 

on the stock ports id just set a rev limiter at 8K
you should peak power at or below 7K on stock ports so theres no real need to go past 7K unless your bored or somthing....

 

Dyno the car.
Lift off when the torque / hp takes a dive.
That's your redline.
