Anyone ever heard of or try one of these?

Never seen it before but it looks pretty good! Kinda like the TurboMaster only easier to install?

Looks to be a spring loaded checkvalve. $89 is pretty pricey for less than $1 in parts.



Still going to need a boost fooler to make any use of it. Further, if you already have the wastegate hose blocked off (like many do running a box with stock turbos) then this device won't do anything for you - you are never 'seeing a boost signal' (whatever that is).





Maybe it works on gassers, but its claims of faster spoolup are hollow on a CTD. I think it will add as much horsepower as a Banks sticker.

How do you block off the wastegate line? What good does it do? I just ordered my edge comp and still have a stock turbo. Thanks guys sorry for the ignorance. I'm just tryin to keep up.

Your Comp should come with an elbow that replaces the elbow coming out of the compressor housing attaching to the wastegate valve. The elbow blocks the air pressure that would otherwise cause the wastegate to open.



You don't want to block off the wastegate until you get the comp on though. You need to 'fool' the ECM by never seeing a voltage level from the MAP that exceeds the stock boost level or the ECM will defuel the engine and set an overboost fault code.



What more boost does is provide more air, allowing more fuel to be burned and also cooling down the EGTs.

its a pricey adjustable version of the elbow that comes with the comp.



take an 1/8"npt needle valve and drill a pinhole in the downstream side of it to release pressure(or poke a hole in the hose) and you get the same thing.....



basically you want to create a restriction in the hose going to the wastegate, with a small port to atmosphere downstream. this dampens the output pressure from the turbo and fools the wastegate into opening later

How exactly does the waste gate actuator work?

How exactly does the waste gate actuator work?

Pressure from the compressor goes through a tube to the actuator that forces a diaphram to move a rod that opens a passage around the turbine wheel, thus bypassing the exhaust gasses through the wastegate instead of over the turbine. The result is that once the appropriate boost level is reached, it remains constant without forming a restriction in the exhaust gas stream.
