I start building boost at about 1600 and see full pressure from 3k to redline. No, it doesn't feel slower.
The car generates about 200/200 at 7psi and 250/240 at 12psi. Runs like a scalded cat.

- Thermostat'd oil cooler.
- Under tray/ducting.
- Some minor maintenance bits; ie: adjusting valves, belts, etc.
- Retune at the dyno.
As soon as we have some numbers, they'll be posted. However, the aim is to significantly increase power at the same boost levels, with the aim of breaking the 150mph barrier *with the top down* on street tires (non-R comp) at the Texas Mile this October.
(Then I'll put a hardtop on it and see what 160+ looks like...)
