hi OZ nBECKS- :-)i have played with third generation eaton m45 and m90,S undoubtedly a well engineered product, leading the way in Roots type blower development,in fact the only progress for a long time!
. Boost is produced by volume displacement rather than tip speed like a centrifugal blower. This alloWs even better boost from zero RPM.
the lubrication system is self contained.so no need for oil lines,returns,or cavitation catch tanks.
i did a bit of work for EATON- but not on the the automotive side,the machine used to produce the unique rotor profiles was made by HOLROYD,it was their install guy that i spoke to ages ago about the kompressor merc before they came out.
these blowers run INCREDIBLY hot,but out in the open,on methanol i see no problem.
its was a pleasure to see and feel just how light these potent little thumpers are.
GO OZCO!!!
I BELIEVE THATS A M45----
