Making 1.2bar with a 1bar RR

Now i know that the weather changes this.

 

So i waited for a warm day and im still making 1.2bar with a 1bar restrictor ring.

 

Does the pressure rise as the revs rise, as in i only get the 1.2bar when coming up to 6K RPM, if i lift off at 5.5k ish then its like 1.15bar

 

Cheers in advance

Are you both getting these results in a long pull in a high gear....?

 

Your 1Bar restrictor ring will just be generic so if you have a particularly strong set of turbos and/or a very free flowing cat back exhaust the results will allow for a higher boost with the same generic sized restrictor ring.

 

I have hit boost cut once with both cats in, pulling in a high gear for sometime when it was very cold, not good with both cats in due to very high EGTs....!

I have a Greddy Profec B Spec II boost controller thats reading boost too.

 

So far i havnt even turned on the boost controller as im running at 1.2bar. My idea was to run 1bar with it off and 1.2 with it on.

 

I'm sure im hitting 1.2 on long pulls too. I'll check tonight if this rain clears up

i have a aem tru boost , with one cat in , when i give it some from start it will read nealy 1.5 bar ?. i thought that with one cat in the car will only boost to 1.1 bar ?

 

 

Are you sure you have the AEM tru boost reading in Bar and not PSI? (14.5PSI = 1 bar)

 

I know you can change it to read in either from the settings menu ;)

 

I know you have J-spec ceramics on your car, and don't think you'd get away with 1.5 bar for very long.
