Just after some info regarding boost compensators. I have a 1990 GQ diesel with a Safari turbo/intercooler system. After reading an article in the July 2003 4wd Monthly mag they say you should fit a boost compensator to an after market turbo system. Is this true or just a waste of money? They comment on possible engine damage if fuel mixtures are not right . A boost compensator ensures mixtures are correct throughout the rev range (or so they say). Has anyone fitted one and noticed any benefits eg more power or better fuel economy? I believe they are expensive, around $1000 I think, could be wrong. Should I fit one or not? or would I be better off spending my money elsewhere? Any input greatly appreciated.

Only if you are running High Boost.

I know dozen GQs with TD42 and various turbos, Only 1 is running a boost compensator, Mark is running 20psi boost on his GQ!

Mate who is guru on these things, says if you go above 12-14psi then yes you need 1. Im runnin 11psi no problems.

YMMV

I went up 2psi and got a woody... Thinking if I went up another 9psi, the undies wouldnt handle it... Quite easily smokes 35's..

Does it have me thinking... You have no idea how often! If the motor didnt have 260,000 on it, or if I rebuilt the motor, I'd probably go 14-15psi.

The thing with Marks 20psi job, his wife drives it to work daily!
