There was a recent topic posted by Goldburg (i think)
asking the spool difference between the stage wheels

I researched it all night, and I'm still confused
all I hear of is stage3 or stage5 (there must be a stage1, 2, & 4, right?)
I am assuming..
T31 is the stage3
T35 is the stage5

and all are available with:
.69, .70, & .76 trim wheels
.48, .63, & .82 a/r housings

I read an SE-R article that said the large .76 trim T31 wheel is a 'low inertia' setup that helps reduce lag
This must have to due with the number of fins and the pitch?

What exactly is a stage3 and stage5 wheel?
The only site that has info on that is FFgeoff's site (fullrace.com)
where stage3 wheel is .76trim T31

So,
stage5 wheel is .76trim T35 ?
if so, then would this be correct too...
stage5 wheel is .69trim T35 ?

Ok, lets look at this in more detail.

A T31 76 trim is a stage 3.
A T350 76 Trim is a Stage 5.

A T31 has 11 blades on it.
A T350 has 10 blades on it.

A T31 consists of these trims:
Stage 1= 68 trim
Stage 2 = 69 trim
Stage 3= 76 trim

A T350 consists of, to my knowledge because there may be more:
Stage 5 = 76 trim.

For comparison, A T31 76 trim(aka stage 3 wheel) has a 2.229" exducer/ 2.559" exducer.

A T350 76 trim(aka stage 5 wheel) has a 2.439" exducer/ 2.798" inducer.

Art great info, as usual

The motor that I'm going to turbo is near 1900cc (+ or - 80cc)
I'm searching for a turbine combo that will let a lot of exhaust gases past it while operating below 4000rpm so that it can behave like a regular NA motor. < This is just a hypothesis ..I don't know yet if it's possible without it suffering from lag.

Should I go with less blades (10)? and with a bigger A/R than .63?

Art thereth anyone besides Art?

If you let too much gasses pass it wont spool. Rephrase your question because I think I know what you are asking, but not 100%.
