Yeah, tell me about it. Ambient temps were ~35F, btw.

If you watch carefully, the EGT's seem to be fairly stable when boost is near 20psi, but then climb rapidly as boost drops to 15psi. Could be coincidence though. (?)

Normally I'd agree, but the guy on the STD forum with 7.5mm elements in his M-pump on a 617 has managed
250hp at the wheels with no intercooler, just a larger T3/T4 hybrid turbo!!!
Click here, see post #14 and #17. That 30psi of boost probably helps.
Note that he went from ~200rwhp to ~250rwhp by increasing boost and the pump rev limit. Still no IC.

I was never convinced that the .97x pumps were the way to more power, and the fact that Myna would charge extra to replace the .97x cam with a .96x cam seemed to at least somewhat corroborate that.
