By definition the end volute will be smaller if the open area of the flange is smaller given the A/R is left the same and you add a divider in the turbine housing.

Result: you'll end up needing a larger A/R divided housing to match an Open housing in terms of end volute cross sectional area.

 

How do you like it, and how is it working for you? Would love to see more data from people!

 

Should be here with everything else in a week or two, should be all in on the 13th and planning to get tune at ER on the 14th...

 

^lol - I forgot you were the OP. Did you ever get a ride for comparison? Are the reds pretty well stocked now, or did you get it used, and is it the 80mm? Congrats on the purchase!

I took someone out for a spin today and they were really impressed with the smooth delivery of the power across the band. It is good to hear that when you are several steps/years away from stock!

*edit - nevermind, saw your post somewhere else re: 80mm. I think 420whp at ER is possible.

 

Did not get a ride, I might be able to check out blkcarbonevo's this weekend when I buy his o2 housing...

I bought the 80mm used, i had the intake pipe, upgarded oil feel line already ordered...

 

^Nice pickup! Someone already dumping a Red for a Black?

 

I think your going somewhere Eric...

 

^welcome back Mikey! How was your R&R?

 

My 3day vacation was awesome! I got caught up on my college!
