Which should I go with GTX2863, 2530, or 2860-5

This thread used to be interesting but now it's dull. Can someone chuck some turbo(s) in a car already and report back (preferably with skid vids)

Or run some laggy twins and blow the 2nd turbo

What is the difference in the number of blades in the turbine wheel? 9,10,11?

One is a square number, one is the same number as most people have fingers or toes.  The other is prime.

Call hypergear... pay him x amount of dorrah... say you want x amount of hp. Recieve turbos... install.. post result

Nah don't do that. Plenty of good turbos on the market

Of course like GT-RS turbos. Comes on at 5700rpm and quickly shift before you 

1. Smash the limiter because you have a "great" powerband OR

2.shift too slowly and fall off boost.

Amazing

To answer your question, it will slightly change the efficiency of it. Depends on the design. What it won't do is make it a multiple times better, eg 11 blades isn't 10% more flow than 10. Remember the more blades you have the more volume inside the compressor is blade. Doesn't help.

Flow is still a function of area and a number of other factors so number of blades is only going to have an smalll change in the characteristics of the compressor. Realistically an optimum design is going to take account of the operation parameters, the housing size and shape as well as the blade design. because garrett or whoever uses x blades in y new design, doesn't mean that x blades will be better in an older, different, compressor.

My highflow was great and my atr45ss cbb is even better. Don't see the issue.

what wheels should I try?)))

these will definitely work
Inducer Dia. : 46.52 mm
Exducer Dia. : 60.13 mm
Extend Tapered Tip Exducer Dia. : No Extend Tip
Overall Height : 24.50 mm
Trailing Angle : 45 Degree
Blade : 6+6

Inducer Dia. : 47.10 mm
Exducer Dia. : 60.13 mm
Extend Tapered Tip Exducer Dia. : 64.98 mm
Overall Height : 29.50 mm
Trailing Angle : 45 Degree
Blade : 6+6

Inducer Dia.: 49.62 mm
Exducer Dia. : 61.98 mm
Extend Tapered Tip Exducerdia : 65.90 mm
Overall Height : 27.63 mm
Trailing Angle : 60 Degree
Blade : 6+6

You need to use only one wheel with an inducer of 62.6mm and an exducer of 83mm mated to a turbine with a 74mm inducer. Preferably in a twinscroll housing.
I can't be more specific as I don't have all the details on these wheels but they seems to perform very well on RB26.

[Mick_o]

I dont know why you are asking? You haven't listened to anything anyone has said all along ?

If they are gunna work use them and post your next failed result! 

I will say this AGAIN.... NONE OF THIS SHIT WILL WORK! So just get over it and buy a single!

I like the way you think! ?

Starts with E and ends in R

No one knows what will work as you are in uncharted territory, you’ll have to just be the test subject

You're a twins guy maybe you should offer him some advice? Pretty sure you've thrown some Frankenfail ideas around here before? What would you recommend he tries next? 

[r32-25t]

For power he’s chasing I’d tell him to go single 

[Dose Pipe Sutututu]

Don't see many fast and competitive GT-Rs at the track with twins.

Most if not all RB powered GT-Rs at WTAC run singles.

They run it for a reason.

EFR is expensive, how about Precision 6262?
