TRD Supercharger Technical Data?? Snout Oil Change?

Does anyone know where to get the actual technical data for the '05 and up S/C? i.e. Rotor RPM @ full boost, pulley ratio. Air displacement HP to run etc?

Also when are you folks changing the oil in the snout?

 

start here?

cant recall what generation MP90 we have, but some generic info is over at magnuson

 

It is a mp90 with internal bypass and built in liquid/air intercooler. Unknown how efficient intercooler is. Link posted is good info of sc rpm, delta discharge temp (non-ic), psi, inlet cfm, power consumption, ect. Rotor rpm at full boost is hard to determine as full boost will be had at any rpm however that number will change slightly due increasing sc ve and motor ve throughout rpms. Pulley ratio is crank pulley I think 6.5" or 165mm and sc pulley 3" or 76mm. This would make stock configuration 6.5/3 or 2.167. So 2.167 x rpm = sc rpm. At 5700rpm oem rpm limiter and 12, 350rpm sc it takes a little over 30hp to spin. They rate them per link to 14k rpm however they can be ran at higher rpm safely for short periods if case temps are in check. For example I ran the trd sc for the 5vz which is a mp62 rated for 16k rpm to over 19k rpm. A company made/makes 175mm crank pulley for the 1gr, and others make sc pulleys in 2.55", 2.6", 2.7", 2.825", and 2.85". Also there are blower upgrades from steigemier to increase sc output. Plenty of options out there.....

 

Thanks for the info!

 

So do you guys do a post break in snout oil change? Or leave what's in there til 100k miles?

 

Whatever makes you feel comfortable..... you can put some mileage on them before needing changed though...

 

This man knows his stuff.
