Hey guys...Im putting and alky kit on my car and getting it tuned in early January. I believe I have all the supporting mods I need.

Im just curious to know if you really need an aftermarket wastegate actuator to control the high boost?

How many of you guys run an aftermarket WGA with alky and what is the stock IX good up to?

Also, is the sole purpose to reduce tapering or are their other purposes?

--------------------------

On a side note, is it true that if I run 100% meth that it can eat away at the engine internals and aluminum?

Thanks!!!

Anyone?

You dont need one although it may slightly help with holding boost. I personally wouldn't waste the money. The nature of the turbo/motor combo makes the stock turbo taper regardless. Seems to me like the Forge WGA's are more hype than anything else, I've yet to see a dyno graph of the WGA gaining power over the stocker.

Is its main purpose just to reduce the taper? It wont do anything else right?

What is the stock WGA sufficient to?

The stock WGA is not a weak point. I saw no improvement in any part of my boost profile when adding the Forge WGA and using alky. I had thought it would help me build and maintain high boost more efficiently, but that was before I understood that the stock WGA is not the weak point, but rather the turbo can't keep pace with the flow of the head. The more airflow you have through the head, the more the turbo will taper.

Beautiful...Thanks Warr

Whats the point of the aftermarket WGA then? Extreme turbo applications? Is there even a point where the stock WGA cannot hold well boost wise?
