Is the new turbo's hot side exducer and or A/R smaller? This could have an effect of increasing your exhaust to boost pressure ratio.

I think just putting a larger hot side on a K27-7200 turbo can add 5% or more to peak HP but it costs about 600rpm in boost response.

I had wondered if one of the reasons you could make so much HP was your larger more efficient hot side that may have traded low end response for high end power.

I do not know if this would show up in EGT's or not. It can be tested for by monitoring the pressure's in the header section.

Hope you get the best of both worlds. Look forward to any update or new dyno's.
