Highest HP 4g63 engine (from 2007)
Sure 
U will not believe how this 64mm comp wheel flows, makes comon shiny 67mm wheels seems small.
sorry for this 
but its true.
The thing is that "billet" loose the meaning when the marketing starts sell turbos.
Practicaly a billet aluminum wheel is not lighter than cast. Mostly hipped cast wheels (Hot Isostatic Pressing or HIP which is a process that subjects the wheel to extremely high pressures and temperatures 8,000 psi and 700 degrees in an inert atmosphere. This process reduces internal voids and improves the grain of the material increasing strength) are lighter than common billet aluminum. "Billet" for me is just a piece of raw aluminum stock that has been either roll formed or forged into shape, from cast the shape and blade thickness cant be done but only from 5 axis cnc and second that cast cant handle over some pressure = rpms speed - strength problems.
The mechanical properties of cast aluminum are limited as far as strength. For these reasons a cast wheel has to be designed with these issues in mind and the blades are made thicker and the center hub chunkier and stronger. So billet have smaller hub = bigger inner vane diameters but same outside diameter so moving more air per rotation and thinner blades than cast.
Thats the real meaning of it. I dont realy know why the fasion of shiny "billet" wheels came out. We use billet wheels from Ti and 7076 at least 10years when we wanted to built something special for cetrain use only. I ensure anyone that billet exact same size and shape flows like cast. We have test and test and test. Sorry from the known companies that i destroy this adv campaign and marketing issues but we dont want to lie to our customers. We built billet wheels specialy for every special test or project and for sure there is anything in cast for us.
I cant write for hours about this.....

correct
from our findings (and being educated) over the past 2 years or so with the billet alum wheels.the slim hub has been part of the big change in the revisions with most of the new wheels out over here-
send me a PM when you are bored-
we can chat-
if on instant message- Slamdvw (dont ask) is my name-

More than one year of preparations and tests here is the result.
A masterpiece of quality and performance.
Just a very quick look of our +2000hp 12.000rpms dual throtle wrc/Lm intake manifold. More than one year tests of +1000hp and 2000hp intake manifolds.
Intalled and fitted with 4 x 2250cc injectors and 4 x 9250cc injectors for the +2000hp project.
Next post will be more detailed from the wrc/Lm intake manifold single and dual throtle, with flow data analysis, fluid dynamics design, more specs and from Solidworks to cnc to reality.
Enjoy

very cool. I look forward to hearing you explanation of how that intake manifold works. I suppose it solves the issue of cyclinder to cylinder flow variance of a side mounted intake manifold.
Spyro-
have you experimented with individual t-bodies- we have been playing around with building some stuff- to test-
CB
thanks for the PM- definetly think we should get together on something

I get to use CMM's, Microvu's, Profilometers, Hardness testers, etc on a daily basis on top of my CNC work.
