HTT Compressor Wheel

Postby cootz » Sun Jul 08, 2007 9:41 pm

So I've got my Stg 4 ready for install,but I'm a little hesitant just yet. The compressor wheel has what looks like machined marks on it,I'm assuming for balancing purposes, but really looks almost like a butcher job. On the back side there is a small indented machined groove. On the front side (the blade side) there is metal missing from the centre section where the nut will be holding the wheel; it looks as though it was machined off too. For those of you with upgraded wheels, is this normal? Not sure I would like an unbalanced wheel in my engine just yet. I'm going to give HTT a call tomorrow, but thought I'd ask here too.

I just got home from vacation, and mine was waiting for me. The wheel looks just like you describe. I'm sure it's balanced and ready to go.

Just enough power to break everything behind the crankshaft.
