T4 Turbine Housing:
.90AR:
Quickest Spool, these housings are considered to be a bit too tight for most 6.7 applications and they are NOT recommended without careful use and proper tuning/fueling upgrades to prevent drivepressure issues. External wastegates are a great option to consider with this option.
1.0AR:
Best All Around Drivability & Performance, this is the most popular selection as it provides a good blend of performance and drivability and is what we recommend for most applications.
1.10AR:
Maximum Flow For More Top End Power, this housing will outflow the others however it comes at a slight cost of drivability, best for hot street/race applications.
Cast vs. Billet Explanation:
The term cast wheel is referencing the material used to produce the compressor wheel. The cast wheels are made of cast aluminum and they are a 7 blade design, this style wheel has been around for many many years and is very reliable. Cast wheel are the most cost effective wheel option we offer.
Billet wheel means that the compressor wheel is made from a solid block of aluminum that is CNC machined to our exact specification. Billet wheels are much more advanced wheels compared to there cast wheel counterparts because we can use a stronger material, more aggressive blade designs, and make them lighter weight then a cast wheel. Billet wheels will provide faster spool up and make more horse power then a cast wheel will. Most of the billet wheels utilize a 6 blade design!
