Setup for compound turbos

RAW, its true a HX35 over any 74/75/76mm primary can make over 600HP. We had a 12V that had that setup and with a blown HG and only making 40PSI on the Dyno laid down 578HP.

To keep the egt's down the built in wastegate is not big enough on the small turbo. Put a bypass wastegate before the small turbo and then redirect the gasses back to the big turbo and you will have very manageable egt's. And it will make maore power. One gent did not wastegate before the small and had egt troubles and then did as I said and his total boost was the same, but egt's reduced and the horsepower was 100 higher at the same boost levels.

So where can one find one of these External Wastegates to work with a HX35 compound system? I found these guys, but there web site is very limited,

If you fabbed your own kit- you can easily make a "bypass" wastegate before the hx35. The mods like hx40 compressor etc to the hx35 are not worth it. Save the money for the skyrocketting diesel prices!!!! And engineered diesel is good - real good - but I am not sure of the price. If you get a 40-60 mm wastegate and use 2 1/4 bypass pipe- wow! And you can get the pre-bent pipes - you cut them and weld - on ebay.
