Turbine wheel/shaft weights.

[turbovanman²]

Building a turbo so I figured I'd whip out the scale and do some measuring. Pics to come later.

Stock stage I wheel-9.1 oz's

Turbonetics small shaft Stage II-10.1 oz's.

Turbonetics large shaft Stage III-10.7 oz's.

Garrett maybe? small shaft Stage III-9.7 oz's!!

^^ I'll be using that one if I redo a Stage III 50 trim. You can feel the difference, of course,

i dont know why everyone is afraid to try the stage 3 wheel

it has the same inducer as a stage 2, but exducer is bigger (about 200 thous if i recall correctly)..cant speak for the F series turbines as i have no knowledge about the wheel sizes...


my 2.2 can spool a bigger then stage 3 exhaust wheel, b4 the cam even knows what to do with it (unless i advance it like 4-5 degrees but that kills some power up top )

Why, because the Stage III wheel is heavy and unless your going to put a .48 housing on, why bother?



Ok, that makes more sense,

How much difference is there between a S2 and S3 turbine wheel? Size and weight wise. And an S5 too while we're at it, if anyone has that info

Please post,



A bit, enough for me to say a stage II is enough for the street, unless you went Stage III with a .48 housing, which kinda silly.

I have all 3 at work, I'll weigh them.




Who and what did he prove?



I disagree, I would never recommend a stage III wheel for a DD, the lag sucks. Maybe an auto is worse but on the 8 valve, I had to advance the cam to make it livable, TIII, its just fine. I was told that the power difference from a 2 to a 3 is neglible.

Maybe the new F wheels are better for you to say that.

Did you get a chance to do this yet?

Not yet eh?

Did you get that datalog done? And Simon, when are you gonna weigh those turbine wheels?

Sorry, work gets in the way. I'll try to do it tomorrow,

Hehe, know how that is.

Since Simon has apparently misplaced his scale I emailed Gpopshop about the staged wheels' weight and spool times. Here's what they have to say regarding the Stage 2 and Stage 3:

Hello again,

Sorry for the delay we have been very busy this week. The weight
difference is just over an ounce. The spool difference is normally
2-300RPM's between the stage 2 and 3. Let us know if you need anything
else. Thank you,

Glad you finally got around to it I take it you have changed your mind about Stage III wheels then.

No, I still say a stage III wheel is overkill on the street unless your looking for lag to help with traction. I have a ported head and will be running some tri-flow cams next year so we will see how that helps my lag.

Maybe the lighter stage III would help with lag?

Maybe, sounds logical. Less mass to get spinning.
