Thread: Boost guage install?? please help

tell your rice boy mate that it goes on like every other boost gauge he's ever fitted.

theres a convenient stud point down near the back of the intake manifold thats excelent for drilling out and tapping to take the fitting for the sense line if you want to read whats going into the cylinders and like all ricers you can just tap the wastegate actuator line if you want to read whats coming out of the turbo. (remove the manifold before drilling to prevent swarf from going into the pots

if you want to get really specccy...

shift the sense line for the boost compensator to the port for the waste gate actuator tap the manifold and use that fitting to drive the boost gauge and the waste gate actuator.

cheers mate

just tap in anywhere. i just cut hose put a T piece and then put boost guage of T piece, bobs your uncle

I tapped the conveniant stud point at the back of the manifold.
found the boost acheived from there was dead on 15psi (or 14.8? :P)

I was thinking to move the wastegate actuator to the manifold too, but didn't think that it would be of any benifit as the max boost was being acheived even with the intercooler, etcetc.

is there an actual benifit to move this anyway??

the benifit of the mod is that you get your boost control off of the manifold which is after the intercooler rather than off the turbo which is before.

this compensates for the flow resistance and the pressure drop caused by the charge air cooling that occours in the intercooler. this means a quicker boost rise as the waste gate stays closed for longer and more power and higher boost pressure.

Putting the boost compensator feed off of the turbo wastegate rather than the manifold means that the pump goes to max fuel earlier on for the same reason.

in reality its only a handfull of KPA difference in boost pressure which may not show up on a cheap gauge but it will help your economy or power depending on how you use your right boot.

Very interesting... compensated boost.. could run into problems if you have a pressure leak though yeah?? Would still be trying to reach the boost threshold but would never get there because of the leak, or have i interpreted this the wrong way?
