If you are a DIY’er you can save some by getting a milled turbine housing, turbine wheel, and gate actuator kit (only applies to certain housings). The 6cm is faster then oem spool up, has egt control to 2500-2700 rpms, and peak hp up to 2700 rpms.
This housing is intended for stock turned up to 400 whp trucks. T3 flange (oem) and 5 bolt outlet (oem) to be 100% drop in. Comes with spring gate actuator.
The hx super 9 housing is a extremely wicked and versatile housing. Kit again is turbine housing, turbine wheel, and the spring gate actuator. This housing has oem spool up speed. Slower then the 6, on par with the oem Charger, and faster then a machined 12cm housing. It’s rpm target is 1300-3500 rpms 3500 being the highest rpm peak hp may be seen at. Egt control up to 3200-3500 rpms. This housing has been modded to use a hx40 dp so a oem type exhaust brake will not work. A hx40 dp and clamp will need to be ordered or if the truck is already equipped with a hx40 dp this is now a 100% drop in unit.
I also have some milled 12cm’s and other odd ball stuff if your looking for something different. Please email or call 209-484-4227 if you have questions.
The milled 12 kits come with housing, turbine wheel, and spring gate. These spool slightly slower then stock. Have a target operating rpm of 1300-3000 with egt control landing in the 2500 area (this has held extremely consistent on the dyno and road testing). Peak hp may be pushed as far as 2700-3100 rpms. The 12’s May be machined used housings or new depending on the on hand.
I am the only shop with the hx super 9 and super 6 chargers. They have been absolutely beautiful to run.
