Here is the ETR-HO S400's based units.

20% smaller hub on the wheels, 11 blade ETR, flow 7% more then the Billet counterparts and 20 grams lighter then the cast and billet wheels.

Unit pictured is our new 80mm.

Dumb question, is 20 grams significant enough to affect spool a noticeable amount? Lets say on an old 12 valve.
 
What would it cost to upgrade to the 75mm version on my S475/.83/.90.
 
Can I get a quote on an S472 EFR whichever turbine wheel you'd suggest for a 6.7 in T4. Thanks

I would be curious what FI says about that, as I would think the comp side of that setup would outflow the turbine side now. Faster spool would be nice though, which would allow possibly a larger turbine housing etc.
