i have a stillen supercharger kit with mattys plate. i am running the stock 7lbs and wated to goto 9 lbs. ive been told all i have to do is swap the pully but i wanted to check to make sure i didnt need to do anything to the fmu. any help would be greatly appreciated.

thanks!

 

i'm running a 9 pound pulley right now with the stock disc for the fmu that came with the stillen kit. As long as you still have the fmu and the upgraded fuel pump you should be ok.

 

cool thx man! what kind of performance are you getting over the 7lb pully?

 

never had the 7lb pulley on.

 

what kinda performce u gettin?

 

3XX whp but i'm sure i can get some more out of it with some tunning nad other little things without changing the pulley.

u think the extra 2 lbs will help with low rpm torque?

 

The smaller the pulley, the earlier the supercharger spins up. You'll boost sooner and have higher peak boost.

 

thats what im talkin about!!! btw is 9 lbs pretty safe? 7 seems fine...

 

nice numbers!... awww man im jealus... i have a 3"-er waitin to be bolted up i cant frigen wait... i gotta tune and upgrade my fuel system first... happy motorin! (dennis gage- gayassfrigenshow)

9 to 10 psi seems to be the safe limit, without additional upgrades to the standard FMU and fuel pump setup.
