Any updates on the wheel? Is it the quickest spooling compared the 7, 9 or cast? HP levels? Flow rate?

Justin which 20G wheel on the 05H turbine would spool fastest? Such as the 6, 7, or 11 blade that turbo lab makes... Also would the 6 blade make more power up top like the 6 blade hx40 vs the 8 blade etc..

Absolutely no clue. Nobody running these turbos are apparently pushing them enough to give any solid input.

Generally-speaking, the lower the compressor blade count the more peak airflow a compressor will make...but this doesn't always apply to each and every wheel design.

Also, keep in mind a 6-blade wheel actually has 12-blades...so an 11-blade compressor has less total blade count than a 6-blade.

I plan on trying one of these out either the 7 or 11 blade on an Sl2 or even 05h... Well see! attempting to talk with Austin now.

My 11 blade td06sl2 is on its way back from Justin so I'll post updates here in a few weeks for anyone considering the billet 20g route.

i havent seen anyone on DSM forums run a 20g of any sort and take it seriously. back in the day the 20g was an expensive turbo to run compared to a 16g. the cast 20g wheel was 170 from mitsu. and the 6h wheel equally expensive. now the china copies are cheap. even the billet compressor is cheap. so now thats is a cheap turbo you wont see anyone with a nice setup running one.

there was some nice results posted over this past year on the evo8/9 forums using the 20g wheels. like 470, 490, and 506 on e85 setups. also guy in UK that purchased the snail 10 blade 20g wheel and machined compressor cover (expensive) for his stock evo 8 turbo. the car is a 2500lb mirage hatch. on pump gas 382 whp he ran 10.96 at 127 with this combination turbo (10 blade 20g 5h turbine 9.8cm twin scroll) he recently rebuilt the turbo switching to 6SL2 11 blade turbine per my recommendation. he picked up 250 rpm spool and 50 whp. he hasnt run it at track yet.

I have been pushing for years the 5h turbine holds the cast 20g wheel back. no one listens.

Thanks for the input! There have actually been 2 people on here who have made 439/440awhp at around 29psi on e85 with similar setups to mine so I'm hoping to land somewhere in that range. Should make for a hell of a street turbo!

Well the turbo just showed up from its stay at Justin's and WOW is it pretty! I can't wait to get this bad boy bolted on and see what she'll do on some e85!!

Please let us know how it goes... I'm very interested on checking how this turbo performs!

But just one question... you mentioned earlier you had the 11 blade compressor wheel, but in the picture I see the 7 blade one.... Did you decide to change it for a 7 blade instead then? If so, why?

Thanks,

I also noticed that...in the pm's between Justin and I we both agreed on the 11 blade so I'm not sure what happened. Haven't had a chance to ask if it was a mix up or what.

wasnt the 11 blade referring to the turbine?

Not in the OP's post at least

I would use the 7 blade compressor wheel over the 11 blade.
I saw a pretty nice hp improvement going from the standard cast 6 blast wheel to the billet 7 blade with no loss in spool.
The 20g is a awesome street turbo.

What turbine are you using?

11 blade Td06sl2

Just to confirm my setup: it's a 7 blade billet compressor wheel mated to a 11 blade Td06sl2 turbine in a ported 7cm housing and a 3in downfiring compressor cover. Numbers to come soon!

I don't even stock the 11-blade wheels at all...the 7-blade units work better and surge less from what I've seen. You got what has logged an accurate 52 lb/min at 33psi on another setup....I don't see an 11-blade 52.5mm wheel working any better than that.

I'll update this thread with numbers once I have them
