Not on a 20g turbo anyways.

Why is it that the top 20g dyno is 461, yet the top 16g dyno is 499? #puzzled
Yep, half the 20g results aren't even over 300whp. 7 of 14 results are 2xxwhp.
I found an interesting read on a billet ball bearing turbo on a different forum.
It seems to be using the 11 blade extended tips and machined to accept the ball bearings.
A supposedly 56lb a min 20g.

Check the 20g 1/4 mile times list, my buddy's old setup is the #2 car, 11.02 @ 126, weight was 2921 with driver. I'd guess the setup was at least 450-475whp, but we never dynoed it.
I think back when the 20g was popular, most people didn't dyno, or own widebands, or have laptops or DSMlink, most had TMO chips at best. The strategy was pretty much turn the VPC another click and see if MPH picks up.
It's great to see a bit of a resurgence of 20g guys, but I think most people looking for a turbo that size either go with an EVO 16g or one of the newer options. The 20g is still by far one of my favorite turbos for a street car, it's combination of midrange and top end is about perfect.
Also, I don't consider these billet wheels to be a "20g". They're just wheels that happen to share the inducer/exducer size. I'm not saying there isn't power to be gained from them, but I wouldn't consider any dyno numbers or ETs to count as a 20g record.
Has anyone looked into Snail Turbo? The made my billet aluminum 20G wheel. They have a 6 blade and a 10 blade 20G for the TD05. They can make custom wheels as well. I would love to someone use the 10 blade on the dyno. My personal one is a 6 blade, (dual blade, so 6 tall and 6 short for a total of 12)
This is true ^^^ that is a high compression beast, pretty sure no one is even in that neighborhood, but still, surely someone could get the 20g to 500 considering curts results.Not all of your top 20G users are getting their cars dynoed, apparently...although 461 is a pretty healthy number for that turbo given it's airflow potential. Keep in mind the 16G numbers were from Curt Brown's car.

The snapshots are nice, but post the log from those snapshots. 2.3l and only 45lb amin seems low. I've hit 45lbs a min on my 2.0 with stock IM/head. With 9:5:1 compression ratio at 23 psi.
Compressor/turbine swaps don't count when comparing airflow numbers between two similar 20G turbos. If that's the case, here's a 65 lb/min 20G:I found an interesting read on a billet ball bearing turbo on a different forum.

I just got one of the KTS 20g wheels here. These wheels are really nice from a design standpoint. I got the regular 20g that weighs 60.5 grams. The blade area is WAAY bigger than standard 20g. More than 15% increase in size. Closer to 20%. Bigger than the kanugawa from what I can tell from pictures. Doesnt necessarily mean it will work better, but sure looks like it will. The material and machining is top notch. far nicer looking in person. The material is also very stiff. I can feel blade flex when I squeeze hard on mitsu blade. But no flex at all on this KTS blade. Dont have an immediate use for it. but wish I did.
