I was wondering how much boost you guys get with the Stillen kit and how many of you have increased the boost from (I think) 5-7lbs using different pullies and who has gone the highest.

Also how many of you have put in ECU upgrades and which ones?

I have done a search around but haven't come up with anything. Maybe I am searching incorrectly?!?

Thanks!!

 

a lot of people have increased boost via the pulley..off the shelf its 3.125 with one going custom 3". Top boost i think is 12lbs with a few running 10-11lbs.

jwt is the only way to go right now with a blower... they just have all the experience.

 

Thanks!

I'll be running a turbo at 5-7 lbs (probably 7) I was wondering how much margin I would have. I know superchargers run cooler than turbos, but I am also intercooled. So does anyone think there would be a problem going to 10lbs?

 

I think it'll be different with turbos like you said re: heat but also regarding the size of the turbo(s). A larger turbo putting out 5 psi will add more power than a small turbo at 5 psi. Tuning is much harder too. The good thing is the potential to upgrade to like Electronic boost controllers etc.

 

Yep also more chance for my engine to go KABOOOOOM!
