i wanna raise the PSI level on my stock twins for races... i wanna raise it to 16-17 psi or so.. other than a boost controller that understands the sequential system what else would i need to make this work right without messing up the turbos or the engine???? i only have a downpipe and an exhaust... i just need to know the bare necessities to raise the boost for a little while????? any help is appreciated...

you need some kind of ecu/fuel management otherwise 17psi is gonna pop it

you need higher flowing fuel pump and injuectors

 

plus a better MAP sensor, doesent the stock one only read a little past 1 bar boost?

 

your limited to 14psi with the sequential system...

inefficiency of the factory intercooler and turbos above that..

providing of course youve done the necessary fuel compensation

 

BOOM.

 

so is 14 psi the end of the line w/the stock twins? what are all the requirements for it? and which boost controller should i get so it understands the sequential system?

 

Just buy a Profec B.

Its the easiest one to adjust ,you can make adjustments as you drive.

 

In my opinion I wouldn't go past 11 PSI. You can boost higher but then you will be buying many other items. If you are gonne raise it only for races then maybe 12. Higher then that and you are going to lose your turbos. 16 and 17 is way out of the question.
