As per my turbo above. No real boost below 4200. managed 128kW@7psi. I reckon somewhere in 140kW@10psi which I'm now running.

I reckon disco potato with the 0.63 rear housing. My advice for the CA18det, NEVER get the 0.86 housing.

My car is very sedate at the moment. You drive it around, and it feels like nothing special, unless you get a clear freeway onramp or open road. You feel like changing gears before any more than 3psi boost is seen when driven carefully. You need the boost curve lower to 'encourage you to give it some' in every gear.

Even crappy cars blow me off at lights, not that I've been trying hard. I could probably get them if I dropped the clutch at 5000 revs, and appeared like I had no respect for: the law; my license; or the long term life of my car.

There's the truth for you.
