normal

 

Yeah, sounds about right, when I downshift to 4th or 3rd ad floor it my car hits close to 1.1 bar then drops to 1 and by redline is at about .9. It used to drop a little lower but I had a boost leak.

 

Slightly off subject but does anybody know the exact maximum bar that is safe to run at with a boost controller?

I thought it was 1.15 to 1.2 bar.
I think thats 16.5 to 17psi

 

1 bar is actually closer to 14.5... and I heard to not run more than 15.5 which is almost 1.07. But again, I'm peaking at almost 1.1, like 1.08-1.09 but it's not for more than a couple seconds. Here's a good site for BAR to PSI conversions... http://www.speckdesign.com/Tpressure.html
