Thinking of changing my hot side of my R85 from a 1.15 to a 1.10 any thoughts on that?

Thanks

T4 turbine sections?
Last time I checked, the T3 turbine was only available in 1.06.

I doubt you'd feel any significant difference going between 1.10 and 1.15.

Doesn't the A/R size depend on how much boost and the how small/large the porting is?

Is it a T3 i thought is was a T4? im hoping going to a 1.10 would help it come on line a bit quicker.

Erdin

Not directly as in you can run high boost with a large port or small port but it will determine ware the power comes on, how much power and how soon. A larger AR will flow better for more top end power but will normally make the turbo come on higher the rev rang and the boost will build up slower to begin with but then build quick. This is what I have found if any one wants to correct me go ahead.

that small a change won't even make a noticeable difference. might as well keep what ya got.

I don't think the housing is a usual T3 or T4. And 1.15 is the smallest one available from TEC:
