Hi JustenGT8
The M90 is only a 90cid supercharger or a 1.5ltr there abouts?
I tried to attached a zip file that has a spreadsheet that list all different types of superchargers where you enter in the rev limit, boost, engine size, type of charger, an will give you a rough idea of what engine HP/KW is, speed required from supercharger and sc drive ratio required, but size off file is a bit to big.
Here is the link where you can get it from to aid you in picking the correct combo for your needs, just click on the blower calculator

With the M90 on a 1UZ producing 15psi and engine limited to 6500rpm, supercharger speed will be over 16000rpm, requires sc drive ratio to be 2.5:1 an will produce about 380KW at the engine?
The TRD unit are a bit bigger then the M90, more like the M122 in size, or a whipple W140AX, Lysholm 2300 or a Autorotor 0A4220, which are all around 2.2 or 2.3 ltr in size?
