20g lovers new 20g wheel!

[94awdcoupe]

Just recieved a couple of td06h 20gs from japan. The 20g blade has been revised. It now has the same lightweight hub as evo16g turbos. The blades are no longer swept either, they are straight. Smaller hub means more air can pass, and faster response. Good stuff.

The three wheels pictured are garrett 60trim, old 20g (60trim), new 20g, evo 16g. The blades on the new 20g are virtually the same size as a garrett 60trim. The garrett wheel is built like a cadillac with a huge hub. The new 20g is the porsche with the lightweight performance hub.

Take some pictures and post them up so we can see

Thanks for the update.

The compressor wheel has a straight impeller? Wow thats a 90* radial wheel. Havn't seen that in awhile. That design was proven not to be efficient due to shock losses at the inlet. I would really like to see a picture of this if you get a chance.

Yeah, let me know, I am considering a 20g.

Yeah, let me know, I am considering a 20g.

^^im with him. let us know what the good word is.

Can you get a new 20g wheel just the compressor wheel,,,

 

[92GSXBaltimore]

well at least we know that Wally is happy with the wheels...

 

[ITSME4G63]

dibs on a new wheel, how much would just the new 20g compressor wheel cost?

 

[LA97GST]

Hm I thought when you said straight fins that they were 90 degree not swept but straight. Disregard my statement about it not being efficient.

Just read about the new Jun Auto Evo 9 in this months turbo mag.

2.0 liters
24psi boost
Greddy TD06SGH20g
493whp at 7200rpm
409tq at 5200rpm

Looks like I was right about the potential of the new 20g wheel.

 

[D_Eclipse9916]

Want to send one my way? or links?

 

[autronicDSM]

I wonder if FP has these yet.

 

[No_Skillz]

Does anyone have recent news about these 20Gs? How much and where to get them?

What kind of lb/min flow numbers are we talking about here?

 

[TSIMonsteR]

Interesting....

 

[2gGSX]

What kind of lb/min flow numbers are we talking about here?

Hard to say since we only have one comprable data point (Evo III). Based on that the increase could be anywhere from about 10-15% (625/550 cite: http://www.stealth316.com/images/td05hr-16g6-cfm.gif and http://www.stealth316.com/images/td05h-16glarge-cfm.gif). With the 20g flowing just under 700 cfm (http://www.stealth316.com/images/td06h-20g-cfm.gif), with the consistent increase of the Evo III compared to the Big 16g, the new 20g would be in the ballpark of 800 cfm (~60 lbs/min)

Disclaimer: please don't take any of this too seriously since this is mathematical bench racing at it's very worst--estimating data from one data point.

Obviously it flows enough to make 490 whp at 24psi.
