What is the minimum amount of throttle necessary for boost to occur with a supercharger on a 3RZ-fe?

For any of you with a supercharged 2.7 3RZ-fe, what percentage of throttle, or what throttle amount (2/10ths, 3/10ths ect) is the minimum amount required to notice the increase of torque?

 

That' a hard question to answer. There is so many different variables...

 

^^^What he said. Pulley size is a big factor....

 

Isnt boost load dependant?

Gentle throttle on flat road may yield nada.

Smash it, peg boost.

Gentle up a grade or towing, u sbould see boost down low.

Its dependent on load and the bypass iirc. Atleast on the 1grfe setup, throttle is only 1 part to the system.
I can do 75+ up a grade and be in vacuum. Having the right rpm, and gear puts less load on engine and i see no boost.

I can also leave it in a high gear and dip into throttle shallowly but quickly and spike the boost gauge.
