3SGTE exhaust manifold pressure, has anybody measured?

[anthonym]

I'm (forlornly) hoping that someone might know what sort of exhaust mainfold pressure might be present in a gen 3 3SGTE? Partiularly in the lower RPM range as the turbo is beginning to spool.

If not reasoned speculation is welcomed, but I'd appreciate it if those of you incapable of independent thought refrained from comment .

Damm, another thing that's been on my list of good things to do for far too long, even got the adapter made up

I don't know how reasoned this speculation is, but from the data I've seen, a typical engine should be between 120-200kpa, depending on whether the wastegate is open or not.

Also by the same author, but with more pretty pictures and possibly a bit easier to understand, though not directly written on the subject at hand is; http://www.vehicular.isy.liu.se/~larer/ ... 02_SAE.pdf
