This person is a really valuable source of information for a lot of people including myself, so I'd rather not say exactly what I found. I still respect what his builds do, and they have some great "firsts" coming out of this shop, but the power numbers confuse me. If people compared dyno numbers to compressor maps, they'd see what I mean. That's all I want to say.

They then release a 500whp kit that is at its limit and undersized for the S54 and start marketing it as a excellent package for track use etc. A lot of potential buyers are disappointed with the outcome, I personally know of three that where cash in hand. The error was that the mid frame turbos should have been used as a start point even if it meant many more months development. Sooner or later the customer with the RHD car at HPF is going to want it back and that will be the end of the development for the RHD cars.
You certainly cut to the point, and I respect that.

I think the existing RHD power band is suited to street driving where you want a quick kick in the pants, then shut it down before the next stoplight. Track guys want a wide and flat torque curve that's linear; this torque cliff is kind of hard to drive on a road course....although the Rally guys love that type of power.
