Holset Turbo HX40W Input

[sleepydsm]

I blew up 2 brand new HX40's until I realized I should probably follow the manufacturer's specs for the drain tube. With a proper drain tube, I have had no issues. I feel like for the size of the turbo, the cost at a used one can be had for, they are great, quick spooling journal bearing turbos. I am very happy with mine now. Using the small Mitsu bolt on housing, a 7.8:1 compression stock 6 bolt, I made peak of 460awhp at DB at 30psi, running out of fuel pump. I think that calculates to roughly 530whp on a dynojet
