New Billet S366 11 blade and S475 7 blade and 11 blade drop in compressor wheels
S366 11 blade specs: 18 grams lighter than cast version, 2.7mm smaller hub = 2.7mm more blade surface over cast version


S475 7 blade Specs: 19 grams lighter than cast version, 2mm smaller hub = 2mm more blade surface over cast version. 13 degree staggered secondary blades.


S475 11 blade specs: 30 grams ligher than cast version, 3mm smaller hub = 3mm more blade surface over cast version. 6 degree tapered blades

I do not have dyno #'s but,
S366 11 blade customer picked up 4psi more boost with stage 2 injectors on a 7.3L and noticed a 75-100 rpm quicker spool.
S475 7 blade test with 300/200 injectors on a 7.3L showed 7 psi increase with about the same spool up time, with a stronger mid and top end pull.
S475 11 blade test with 300/200 injectors on a 7.3L showed a 5psi increase with 100 rpm quicker spool up time, with a stronger mid and top end pull
Wheels are pre balanced but i do recommend a rotating assembly balance.
I will do a free installation & re-balance with purchase of compressor wheel. Only thing you have to do is cover shipping for cartridge both ways. 1 day turnaround.
Please pm, email or call for pricing. -- James
