New Newbee

Hi I have just joined.
We have a 2006 3L Patrol which we bought from new and I still cant believe it ours. I just love my Patrol. It has the usual gear Bull bar, snorkle, winch, lockers, 2x radios, wheel carrier, roof rack, batteries and lots more.

The last thing that went on was a Tiapan 3" exhaust with steinbauer chip. (Boost guage and Pyrometer guage fitted as well.)
Has any one else fitted this config ? We live in regional SA and our mechanic is good but I want to know if a dawes valve needs to be fitted as well. The boost guage is very talkative.

Thanks

Welcome to the forum Snicko.

How high is the turbo boosting?

Welcome to the forum Snicko!

The first time my mechanic set things up it hardly moved at all. The second time it spiked at 26. The next time in 20s, the last time the same

It might be worth fitting a dawes/needle valve set up to control the boost better and eliminate those spikes. The dawes/needle valve set up gives full manual boost control, a dawes valve on its own can be used to leave the computer in control but eliminate spikes.

How dangerous are the spikes?

Not particularly damaging to the engine but not good for the intercooler, can loosen the end tanks or blow hoses off.

Tony

If this happens does it show up on the guage or something worse happen?

G'day Snicko

Welcome to the forum.

Take care out there.

If a hose blows off you loose a lot of power and blow black smoke. May show on the boost gauge depending on which hose and where the boost gauge is plumbed in.
The intercooler will be more subtle and over time show as an oil leak on the intercooler core.
