Hi,

im running jspec turbo 2 stock turbo with boost controller, and knight sports fbcd, and a bov.before teh BOV I was getting only 6 psi max, Iguess the stock BOV was leaking. Its alot faster now and shoots even more flames especialy on the freeway. Im getting about 10 psi max, but I know some ppls are running up to 15 psi with the same setup. How is it done? Did tehy remove some kind of vacuum?

 

well they are idiots then because the stock turbos loose efficiency @ 12psi then beyond that there seals on there engines are gonna break soon running @ 15psi unless they are upgraded seals...

 

It (15psi on mostly stock components) is done either:
A) unreliably
or
B) with a fmic, upgraded fuel and injectors, and fuel control; all that being the minimum.

 

well they do run a 255 lph fuel pump,a nd teh top mount intercooler, and so do I. Im just trying to get the most out of the stock turbo., Just wondering if you guys knew what to do..

 

would porting the throttle body and dong all the diy work help?

 

yeh, it would help
but not too much really would be gained.

just go single turbo

 

You can run close to that level of boost, with an upgraded fuel pump, and ideally some 720 secondaries. You'll need a S-AFC to adjust the secondaries. And you'll need a boost controller of some sort. The simple boost controllers bleed air off the line going to the wastegate.

 

yea hopefully you didn't just turn up the boost and not add any fuel! If you did you will be blowing yout motor soon!

 

upgraded seals???You mean fuel hopefully~~

 

yea I want some of those ugraded seals!

 

lol yea i read that tooo ... i hope he meant fuel
