Yea if you get a chance to get some weights, that would be good.
Do they make a FMW for the s472?

Yes and no, they have had one out in testing that a few were able to get there hands on. Everyone raved about it so it's going into production. Not sure when it will be readily available.
I know with our s482/96 stuff we build for twins, guys have notticed differences in the 7 vs 8 blade wheel. 7 seems to work better for peak power, 8 works better for street/response.

When I bought my 80mm billet wheel, the company said there best design for power was 7 blade as well.
Fleece has some 6 blade billet wheels, but not cheap!

Yea I'll stick with what I have before dropping that kind of coin on a wheel swap.
For that price, I'd also be curious to see the difference in Stainless Diesels 5 blade mafia wheels. I wonder the weight difference between the 5 blade and 6 blade wheels.
My industrial turbo was stupid loud, my fpe one now isn't that loud but you can notice it's there when cruising.
Just checked the three versions of 67.7mm we carry. They are all genuine Borg Wheels. The cast 7-blade was 202.3 grams, cast 10-blade is 185.9 grams, FMW 7-blade is 201.8 grams
185 grams for a 10 blade. I would have figured heaviest for sure. Maybe my thinking is not so accurate on more blades being heavier.
Jacob, do you happen to have a cast 7 blade 72mm wheel laying around you could weigh? I'm curious how it compares to the 75 mm wheel since they share the same 101mm exducer.
There aren't actually more blades though, the 7-blade has 7 full height and 7 half height blades, so they are technically 14-blades. The 10-blade just has 10 full height blades.
72 is 271.2 grams, 75 is 275.8 grams
Yea I see what you are saying, I still figured 7 full+7 half blades would weigh less than 10 full blades.
This is good info. I like it!
My bullseye billet wheel in my 66 did great for 3 years batmo is okay but not a fan of them myself
Bumping this up for reference.
I swapped back to the cast 7 blade wheel in my s472. Finally had a chance to weigh the billet 11 blade 72mm wheel I was running. I was actually quite surprised at its weight, thought for sure it would have weighed more than the cast wheel.
Cast wheel 7 blade wheel is 271 grams.
Billet 11 blade wheel came in at 245 grams.
Even swapping to a .90 housing from the 1.0 housing I was running with the billet 11 blade wheel, I can tell the cast wheel spools slightly slower.
