Turbo Boost and model - scottbmxer - 09-07-2012
Only getting max boost around 16/17 psi with the wastegate arm on last 2 turns and running max fuel! Also any ideas on which turbo I have??

Could be a worn wastegate being pushed open or a boost leak
Don't know what turbo it is though. Being a later model I'd think ko3 or similar
RE: Turbo Boost and model - Jenkosowls - 09-07-2012
turbo seems rather leaky
RE: Turbo Boost and model - scottbmxer - 09-07-2012
Ive noticed in first or second before the the boost has just dumped at around like 3500 4000 revs causing the car to slow down massively like I put the brakes on!
going down motorway and stuff it will stay at a constant boost no problem
Btw when I mean max fuel i mean 45degree's or slightly more on lucas pump!

The manifold looks different to my old T2 and k14 so i'm guessing it's a GT15
RE: Turbo Boost and model - ash23 - 09-07-2012
That's a k03 should got more out of it than that mines boosting 1.4bar .

What you mean before "the boost has just dumped"

sometimes the boost just dumps around those revs in first and maybe second! I just loose all pressure and it slows the car down massively like I have put on the brakes.

how much did you tune your lucas to get that 1.4 bar?? and is your waste-gate arm really short like mine? like on the last few threads

RE: Turbo Boost and model - 4WayDiablo - 11-07-2012
Make sure there are no leaks. And fit a MBC to adjust boost easier

28psi here (1.9 bar) on a K03 here!
But sounds like a busted turbo; I shouldn't cut off, at higher rpm, the turbo will start to loose boost..
RE: Turbo Boost and model - David - 11-07-2012
if it is a busted turbo then drive it normally but i say its bigger turbo time
RE: Turbo Boost and model - scottbmxer - 12-07-2012
Was going to upgrade to a T2 what do you think??
RE: Turbo Boost and model - samass - 12-07-2012
go big, or go home. td04 or the like
not that i know anything about dervs, but from what i know, the t2 is the 'best' standard turbo they put on. might as well get a big un on it for more gains and whatnot
RE: Turbo Boost and model - 4WayDiablo - 12-07-2012
Pretty much what amass says.:-)
