Nice video. To many guys are buying big turbos not realizing the sacrifices that come with it. I years ago, was one of those guys. Great info!

You are one of the few shops that take the time to explain the theory in turbo performance that bigger isn’t always better for Diesel engines and matching the right parts for its intended use... It reminds me of the old days with people hot roding gas engines and always wanting a big camshaft because it sounded cool with the “lopey Idle” but would give up a ton of drivability and performance when matching the wrong camshaft to the rest of the engine and application use! Great video!

Great video! I feel relieved I kept my valley charger stock and added a precision 67mm on my f250.

Compressor wheel and turbine wheel design are huge not just size. Wheel profile , extended tip , slim hub , then the pressure your looking to make will dictate how many blades youll have 11+0 5+5 6+6 and AR and wastegate size to combat back pressure. There so much more to consider .

Great video. I was thinking of going with the 67 on my lml but I think I’ll be changing that to a 64 Or compound.

Could you do a video on sizing compounds turbos for different applications?

What's your take on 11balde compressor wheels vs others?
@Treason53 4 years ago

How much different is the spool-up of the 64 from stock and the 67 from the 64 in the VVT models? I have a 2007 LBZ that I’m going to be studding and adding some fuel soon and can’t decide if I want the 64 or 67, planning on around 650 to the wheels (stock bottom end) and tow somewhat regularly (anywhere from 3-12k lbs) and all at 4500+ elevation. Both maintain the turbine brake so that’s a plus
