lets talk turbine wheel size

So people are going to bigger wheels for better top end performance and less drive pressure more so than anything. I'm trying to figure out how to spool at low rpm Tcc locked for towing while still getting high end performance. Still seems compounds would be the way for that. But twins would be easier to do....

Because a t4 won't make the power I want. My tc78 is a out out of breath as it is. It spool good but when towing a heavy load up a steep slow grade I had to drop gear pretty far to be able to keep the Tcc locked and build boost. It actually did pretty well but not as well as I think it could. I don't wont many more cubes I'm trying to keep mileage decent while not in boost. I think I can have cake and eat it too if I bake it correctly. If nobody ever tried anything new we wouldn't have so many 9 Second turbo trucks around.

Well mine only has a 77mm exducer and its great! But I know that turbonetics came out with a new turbo with huge turbines. Don't know the exact specs but maybe someone will chime in
