Whats best for Wakflield?

grosso
8500 rpm red line which gives me 450nm Torque from 5500rpm or change red line to 7000rpm and increase Torque to 500nm?

Just BLOODY drive the thing & hope it's reliable is about all i would be worrying about 😣

I echo what Mikey said. My advice is to have fun

Been driving the last few days now, testing and stressing the motor for weak points. It seem to be very good now I have iron out all the problem at this stage still testing it all the next following week. Taking it back to dyno shop before Wakefield double check every thing. Hoping I have covered all bases. I am setting the shift light to 7000 rpm even thou soft cut is at 8400 rpm just to keep boost down. This car is heap better than last year with brakes and torque curve fixed. It comes down to if I can drive it hard. So the plan is to have fast fun.

More bitumen, less dirt.
Avoid Evo drivers.
Store your beer safely. (avoid evo drivers)

With that much power, you could drop the limiter to 6000rpm and still run a 1.10.
If not, you need to driver tune, not dyno tune.
