The Stealth Mach 1! Lower EGTs, Quick Spool. The Ultimate Turbo

[@Re-engineer_everything]

What would be optimal with a S475 compound. Mike is my tuner for my weird ass truck.

@JeremyCricket What model and year of truck are you planning on putting the S475 on?

[@Re-engineer_everything]

@@Duramaxtuner 2003 Silverado CCLB, LB7, 30%, stock/S475, DT750. I’m thinking bigger Turbine wheel.

[@Duramaxtuner]

@@Re-engineer_everything We have used our LB7 Stealth 64 in a number of compound setups that use a S475s. It comes with a larger high-flow turbine (10 blades instead of 12) which actually spools very similar to stock but flows much better and does a much better job at keeping EGTs down. However, please let us know that you are planning on using this turbo in a compound setup with your S475 when you order so that we can properly adjust the water gate prior to shipping. If you have any questions just let me know or give us a call!

Hey bro are the mach ones going to be added on your website soon Or is it the stealth 64 ? For the lb7.

[@Duramaxtuner]

@jarvisgarcia5680 The LB7 Stealth 64 will become the Mach 1 once it passes Emissions Testing procedures and accordingly the Stealth 67 will also become the Mach 2 once it has passed. Mach 1's will slowly phase out the 64's over time. However, the LB7 Stealth 64 should one of if not the next turbo to get this branding.

Would the mach 2 LML be an upgrade over my stealth67g2 with the 11 blade comp?

[@Duramaxtuner]

They would be the same. The 67G2 is an 11-blade wheel as is the Mach 2. The major difference is that the Mach 2 has undergone and passed 49 state compliance testing.
