    EFR vs GTX spin off

    Thought this video might be cool. Its the two biggest turbos on the market and it shows them spin. First is a efr 7670 and second is a gtx3076. Both of the turbos were mine

    Awesome video, the only thing I could see being a factor is the lack of oil in the EFR because it isn't in the car.

    It wasn't dry, they both had equal amounts of oil in them. Both weren't operated for about a day only difference is one vid was while the GTX was still on the car and the efr was just taken off

    Can someone explain to me the advantage of switching the iwg the efr comes with to the billett actuator full race sells on their website. I know it allows you to run a 4 port boost solenoid but I don't know why this would be necessary or the advantage it would provide. Whats wrong with the iwg canister the efr comes with? Any input?
