Bighead wastegate

[GOEGLEINBROS]

Has anyone done just the bighead wastegate without the new housing and ww? Does it make a diff? Anyone with dyno results with the bighead alone? The reason I ask someone offered me one the other day real cheap, but I'm not sure if the bighead alone would do anything. Any info would help...

the bighead wastegate should make an improvement on the boost side of things (faster rise and should hold boost pretty steady throughout acceleration). should help on the get up and go from a stop. i dont think it will make any difference in power numbers. but should make the turbo a little more responsive. you might want to look into a WW or something to that effect also

The BHA will help keep the WG closed since the stocker is weak and can get blown open by the backpressure.

As far as dyno #s....I doubt it would add any HP if you don't add fuel.
