L33 Posted March 13, 2010 Author Share Posted March 13, 2010 Well I've done a few runs today from diff speeds and gears with the boost controller off and the boost is constant 1.3 bar So because its constant does that mean the manifold and waste gate are ok?

Scott Posted March 13, 2010 Share Posted March 13, 2010 Depends what rate spring is on it bud. If it is a 1bar spring and is boosting to 1.3bar it means there is a bottle neck in the wastegate port. Quote Link to comment Share on other sites More sharing options...

L33 Posted March 13, 2010 Author Share Posted March 13, 2010 Was mapped to 1 bar, but its not goin above 1.3 at all so I guess that's good compared to the 1.5 that was before! Only a couple weeks then its over to ryan any way Quote Link to comment Share on other sites More sharing options...

Only a couple weeks then its over to ryan any way If its only mapped to 1 bar you want to be very carefull, id hate to read a post saying lots of smoke.

dude Posted March 13, 2010 Share Posted March 13, 2010 Since I pulled the trac fuse out I can now spin the wheels as I had to see what diff it was, I have a torsen as there is 2marks and not a lsd as I tested when on a ramp off ground as I was able to stop a wheel with my hand Told you so;) Quote Link to comment Share on other sites More sharing options...
Kev.O Posted March 13, 2010 Share Posted March 13, 2010 How was it mapped to 1.0 bar if you're not getting as low as that now with the boost controller off? Quote Link to comment Share on other sites More sharing options...
dude Posted March 13, 2010 Share Posted March 13, 2010 Torsen is LSD. You cannot check for a torsen diff by jacking and spinning the wheels. Torsen mean "Torque sensing". I.e. if you jack the back up, there's no torque on the other wheel so it will act like an open (non-LSD) diff. The only real way to make sure is to take the back plate off the diff and see whats there, or do the burnout test. I prefer the latter Not quite true dude a LSD will have clutches like a TRD or Kazz and if you jack the car up both wheels will turn the same wheel, a torsen works like a centrifugal ratchet and when jacked up wheels will turn opposite ways like an open diff.
