Turbo experts,
I am just about to fit a turbo kit to my 1HZ Troopie, and decided to fit a pyrometer and a boost gauge for protection purposes... Now I would be really pleased if anyone can give me real life experience of what EGT (before turbine) and boost levels they have run for many many miles without durability issues? I am reckoning that 700c max and half a bar is probably normal. The boost reading would be at the wastegate actuator pipe. Can hardly wait to get out the spanners!!!
thanks in advance,
Gil

Depends on where the Temp pickup is.. it can make a 100-150 degree difference.

but general rule is 550c temp... boost, depends on the setup, and how it was dyno'ed, but 8-10psi is good.

Interesting how we talk temps in deg C, and pressure in psi :o)

I even have a EGT reading deg C and a boost gauge reading psi!

Yep, 700deg before the turbo and 8 to 10 psi, or 0.55 to 0.7 bar gives some reliability.

Firstly- I am by no means an expert....
'Turbo Dynamics' (now Denco I think) system fitted 8 yrs ago.
No durability issues.
Checked (along with pump etc) every couple of years or so.
Regular oil/filter changes.
Silicon hoses replaces a couple of times.
EGT fitted after Turbo- so not relevant..
Max torque 400Nms (unturbo 277)
Max power (at rear wheels !!) 80HP (unturbo 51)

Grease up the spanners mate !!!
