Pic's of shaved turbine housing
Hey guy's i was just messin with the explosion comment...awesome job machining tho for sure.

Either way, who cares? Its lighter than it was before. Shearer is thinking outside the box. He is a smart dude, as is tial. You think that turbine housing is thin? You should see my FP HTA GT35Rs with the Tial turbine housing. Pure engineering sex. period.
This is good stuff, step back and take a note. Dont bash, and you just might learn something.

i'll give you some facts...
the way Garrett makes the housing is simple, one external dimension for all A/R's which means from the outside it is the same for .90 through 1.40
as the A/R changes the wall thickness gets reduced, so the lower the A/R number the thicker the wall.
the .90 and the 1.00 A/R garrett housing can be machined and ~20lbs taken off and still have a wall thickness greater than the 1.40 A/R which Garrett blast tests to make sure containment is achieved. so you end up with a light housing that still has a wall thickness that is able to blast contain.

On another note, Garrett does test their housings for containment up to 110% rated speed (If I remember correctly), and is really cool to watch

That is strange because I remember lifting some of the GT55 housings and the weight seemed to increase with larger A/R ratios. Also, why would Garrett go through the trouble of having multiple housing castings made and then not reduce the price of the raw material by controlling the wall thickness on the smaller housings???

Im shaving the turbine now as im struggling to fit it in the desired position without making it smaller, does anyone know the minimum thickness I can go to?
EDIT- If it helps, I just measured the wall, we talking 17-19mm wall thickness all round at the moment.
