I am wondering what boost the turbos charge in stage 4 kits with k24/26 turbos? For example fvd´s stage 4 kit.
For gt2 that is...

 

Are you asking when they hit full boost or what is the max boost they will
run before they run out of efficiency??

My 24/26 spike at 1.3 bar. But this is from a 993TT.

 

the st up will hit 1.2 bars then drop off to 1.1 bars.... u can upgrade the WGs and if installed properly they can aloow 1.3 bars... Throttle body shutdown will occur at 1.3 bars so its a fine line between max boost and TB shutdown...

1.2bar is about right for FVD stage 4 cars....

 

My car is a stage IV fvd except for the air intake plenum and Max. boost i saw is 1.2 bar.

 

I run 1.2 BAR on stock K24s. In the higher gears you get 1.3 showing for a split second before the wastegates open up a bit and bring it down to a solid 1.2.
