I remember reading that boost controllers do not work on the Polo's. How does this air flow controller work as from what I understand it restricts air to the Actuator. This is what boost controllers also do so how does one thing work and not the other??? (sorry if this seems a little off topic but I'm interested in the answer).

Correct me if im wrong, but if you control the air to N75 which is the boost controller, then you really are still doing the same job as a manual boost controller, but only it will be smoother correct?????? Looks like you are restricting the input to N75 and then of course this will alter the output from N75 so i can see how it could be smoother as the ecu still drives N75.

Funnily enough i have been talking to a mate about this exact same thing as well. He said if you put one of these valves in it restricts the boost from getting to the wastegate until a set limit. So if the wastegate is bleeding off early, the valve wont let the air get to the wastegate. which means more boost longer. but does this have an effect on AFR, and the boost requested and actual boost??
Please correct me if im wrong....Last edited by shaneth; 29-01-2009, 11:09 PM.

Not to mention eliminating the ram-air effect of the stock intake mouth and air box......Originally posted by marko View PostLooks good!
Although I reckon that unprotected pod filter will be hurting your performance quite a bit. Possibly more than the stock air intake. Those things really suffer from heatsoak when they are just sitting open in the engine bay.

This would have more of an effect if the car was N/A. As the car is forced induction, this has little or no effect in the grand scheme of things.Originally posted by Buller_Scott View PostNot to mention eliminating the ram-air effect of the stock intake mouth and air box......

I think the boost controller can’t block the air completely to the WG actuator.Originally posted by JCM308 View PostI remember reading that boost controllers do not work on the Polo's.

I have a HKS boost controller in other car, in the manual it says 1,5bar is its maximum pressure. However this industrial valve can hold 10bar.

Yes!

Yes it affects the AFR, but the electronics can handle. The MAF is reading more air flow and the Lambda meter is correcting the fuel mixture.Originally posted by shaneth View PostFunnily enough i have been talking to a mate about this exact same thing as well.

The electronics will try to protect the engine is something is wrong.
After 1,6bar that vacuum box over the engine is opening my BOV, holding the pressure at 1,3bar. So I pump the throttle and the full boost come again.

This is two in one dynameters runs.
The blue run is with the car chipped, only with the air filter.
Look the Roller Coaster, that is the WG opening and closing.
The red one is with the exhaust done, N75 race and the Festo valve.
At the dynamometer it shows the loss of the peak power, however I didn’t felt it when driving the car.
Power agaist torque.

You sure this works?Originally posted by Plautos Cattalini Lins View Post
The next day I install a Moroso breather valve, the engine fumes and oil vapors they are not going to the TIP anymore, now they are going to the exhaust. No more oil to the intercooler.
Today I change the rims, I installed a set of Center Line’s Storm wheels. They are 18x7. I’m using Yokohama Parada 215/35.
Intake pipe has a vacuum affect as it draws air in it also draws oil vapor form the crankcase. The exhaust on the other hand has pressure in it, which in turn would pressurise your crank case.
I have never seen a kit like it before maybe you can tell me how it works.

The golden piece is a one way valve. It opens only with positive pressure inside the engine, so exhaust gases cannot come back thru it.Originally posted by Bubu View PostYou sure this works?

We have pressure at exhaust manifold, not after the turbo.
At the end you can see the instruction manual.
