When your flooring it, what RPM do you get to peak boost at? In 2nd and 3rd I seem to hit 1.3 bar at 5500-6000 rpm. Whaddya think? That seem about right?

It probably depends on how your boost controller is setup and what turbo's you are using.

 

I can run 1.5bar in 2nd / 3rd gear by around 3300-3500rpm.

 

A friend of mine has the GT2530's fitted and his boost doesn't run strong until past 4500rpm

Fook me !! what turbo's are they? they must spool up hellish fast.......

Yeah mine's a lot lower than that too Adam - maybe its to do with decattedness?

Ahh, just seen you've got decats in anyway. Probably means your car is slow :D:D

5.5 - 6k is way too high to be hitting full boost, I would be lookin at vaccum problems or boost controller installation/setup.

I don't know how you do it on Apexi stuff but on the Blitz controllers you set the maximum boost and a "gain" figure.

The gain affects how fast the boost builds up - too low and the boost builds slow and smooth, too high and it can cause overboosting too quickly.

Increasing it on my stock turbos made a huge difference and made the car get on full boost much earlier.

tried mine on the way home for ya (thats a fiver for fuel you owe me ;) :D )

 

start to hit +ve boost at around 2500 rpm & 16psi at around 4000rpm (i think!! the boost gauge & rev counters mooving so quick by then!!)

 

manual car, JWT teapot, stock turbos, JWT induction & Mongoose zorst, lightweight flywheel still got the cats on (really should get them off! :rolleyes: )
