Does GT35R + T4 Divided 1.15 A/R = LAG?
This is on a 4g64 2.2l CR 10:1 E85. If someone who has first hand experience would reply it would be most appreciated.

The Garrett white paper which I have unfortunately misquoted before, goes something like this-
A divided housing will spool as though it were 60% the size it is. For a given power level on a undivided (this is the part I misquoted) the divided housing will need to be 1.2x larger than the undivided.
In normal terms-
A 1.15 will spool like a 0.69 A/r T4 open (1.15 x 60%), but have the max power potential of a 0.96 A/r (1.15 / 1.2)

This is awesome it spools faster then a SS T3 .82 A/R and has more top end power then it I'm sold!

The .82 edged out the 1.06 up top by 11hp but the 1.06 had it all the way through the power band up until then. I reckon the 1.15 would edge it out up top.

1.5 inch or 2 inch runners on the exhaust manifold? On the 1.15 it would work well either way I suppose.

If you didn't buy the turbo yet then go with either a 6266, 6466, or FP35Hta with the bigger turbine wheel. I forget the size. The 35r turbine is small imo. Use nothing smaller then a 1.00 housing. 1.15 being perfect.
No it will not = lag. Your going to spoolup quicker and harder then a open t3 .82 setup
