    Hx40 7 blade power output?

    Hey guys just need a rough idea of what this turbo will produce on a built aan motor, I know it varies with everything done intake etc, just need a rough number trying to calculate if my spec stage 3+ clutch will hold the power or should I be looking at a bigger clutch :/

    is it the super 40? i suppose the super 40 can make up to 600hp, so it could be at the top 6xxNm. However because the turbo spools later and gets full boost after 4200-4500rpm i think the spec3+ should be able to hold.
    I changed mine because i switched to the single mass, but for a little while when i was testing the HXsuper40, i did up to 1.8bar and i didnt feel the torque was too much to handle(although i was using a southbend clutch).

      Here's a plot from a friend of mine.

      Everything less than 2 bar is considered to be naturally aspirated

          yeah i believe it is the super40 and im using an aluminum flywheel, so im guessing i should be fine with the power an hx40 can output wouldnt be more than what the stage3+ can handle?, or this might be a hit or miss scenario.

              Super40 with #16 or 18 housing, cannot remember 100%, as it wasn't my car.
