We're sticking to the 70mm to keep the blower below redline. Twin screws do not like to overheat.
We made a little piece the other day that seemed to pick up another 10hp, and the JDL header should be here soon. I think that and some cooler weather should see it go to a confirmed 300whp.
With everything in this thread I seem to have neglected what a blast it is to drive this car...though always an ardent turbo person, this is just a totally different driving experience! Nothing like power sliding third in the torque dip
