Hello all,

A bit of market research here;

What are the current requirements to increase boost?

Has anyone tried uprating their waste-gate actuator?

If so, what are the best on the market (currently).

All feedback is welcome.

Kind regards,

PA

I put a ball bearing in my waste gate hosexand made 42lbs of boost.

Weld the gate shut. No need for waste gate actuator.

Exponential boost increase with RPM.

I took off the wastegate line from the turbo

You can just retune your car to make more boost, as the ecu controls the boost to a certain amount. Usually double what the actuator is capable of. Eg a 7psi actuator is good to about 14psi. The garret actuators work very well.

Upgrading the waste gate actuator, what a great idea, wished I thought of it.

I just tied a knot in the hose , but should have used the ball bearing method as I only made 33.3 PSI

all the above methods work really well, but for even extra boost (and if the budget allows) use one of these:

Are these pneumatic or electric actuators?

By adding a ball bearing to the pressure hose this renders the actuator useless, thus having no boost relief curve. Will just be a sharpe on off with your boost which is not good for the turbo

Great suggestion.

If you do a brake upgrade at the same time. http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=130962922923 , he will combine shipping.
