Last steps completed on this build rolleyes.gif
I bought a billet compressor wheel for the CT26. The goal was to have more air beyond 5500 rpm because that is the point where with the stock CT26 pressure started dropping.

I built it on a spare CT26 so that I could send it in for balancing and still was able to drive the car...it's actually my daily biggrin.gif
The result is very satisfying: It does exactly what I hoped it would. I now have still 1 bar of boost up to 7000 rpm. from there it starts losing pressure, but there are anyway only 300 rpm left till redline.
Calculated power is now at 350 hp and 317 ft/lb of torque (at the crank)... Compressor efficiency must also have gone up, because percentage wise I gained a bit more power compared to the increased boost pressure.
I'm done searching for more power tongue.gif
I mostly did this step out of curiosity about the billet comp. wheels... I just wanted to know if/where/how it makes more power.
