lets skip the appetizers and dig into the meat of the conversation.

heres my current setup:

comptech supercharger 1220sl stock boost @5lbs
DC header
nvidia 70mm testpipe
stock exhaust
(I've read all about the SL blower and issues, currently mine is running fine)

So i want to get flashpro and get tuned. My goal is to optimize the charger at a safe boost. So I want to ask you veterans on the subject if i should purchases SOS higher boost pulley and which pulley (lbs boost) you would think is a good option. Also, i plan on keeping stock exhaust since i love how it isnt loud, haha. Pretty much im am looking for any guidance so i can do it right the first time. Thanks in advance for the help.

 

Why are you only running 5 lbs right now? My 1220 SOS kit is at 6 psi. Anyways, I'd go for 10 psi, no more than 12 with the 1220 blower. 10 psi should be in the 1220 blower's sweet spot in terms of efficiency. I plan on going to 10-12 on my 1220/SOS setup soon.

Stock exhaust is more than fine. I'd probably go back to the stock header.

 

I called SOS and looks like the pullies they offer wont fit comptech brackets. SO i called comptech and they do not offer a higher boost pulley instead a stronger crank pulley to get another 2 lbs of boost they say. Cost was about $150ish.

 

I am not familiar with pulley fitament issues on the CT kit, but a 3.8" on a 1220 yielded almost 10psi on my AP2.

 

Thanks for the data point. Good to know when I finally decide to up the boost.

 

Ct be hating. Bummer. Well at least go to 7psi. Get flash pro and Evans et une. Then enjoy
