>T04E-50 compressor /T3 turbine Stage 5 wheel, .48AR. What are your horsepower goals? That's a big wheel in a small housing on the exhaust side. The T04e 50 trim wheel is pretty proven to the 400-450 whp level or so, but guys are having very good luck with the new 56 trim wheel. 450 on pump, 600 on c16. Mmmmmm, good. -Jay
