I downloaded a pdf from a holset page with maps for a 35 and a 40. Sorry lost the link and the file:redx:

I have the H2E, HT3B, the "real Dogzilla Holset map", and two other HX40 wheels.

All are actual Holset maps, not some cobbed up stuff.

Don't be shy- post them up

S300 s400 and more http://www.centralturbos.com/pop-werks6a.htm

A more detailed map of the s300. The poster said he got this from HTT, but its identical to the above s300 map as far as I can tell

Extra tip on reading maps..
In a twin setup, the little charger's pressure ratio is the intake pressure + 15psi / inlet pressure + 15psi.
Like mine I see 30 out of the big one and 85 in the intake so the pressure ratio is 85 + 15 / 30 + 15 = 2.2
And the air flow in lbs/min is junk when you are looking at twins. Divide all of the lbs/min by 0.076 to get cfm. On the little charger, divide the cfm of the big charger by your pressure ratio.
