Ford tech here, just wanted to mention that this is a great video! Nice to see some accurate information laid out smooth and efficiently. I'll be pointing customers here when the get that HP/ TQ itch to help understand what works and why. Thanks for taking the time, I'm subscribed.

From a Ford guy!

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!

This literally answered every question I had about upgrading my turbocharger. Great video 👍🏼

[markrich]

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 .

Thanks for the video. I had a basic understanding of turbos. Now, I have much better understanding.

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

The best no bullshit heads up video/section there is

[djjamar]

This was great advice. Thank you for putting it in real world examples.

[FlatPlaneCranky]

Very informative! I’ve been wondering which turbo to upgrade to with my LBZ and you’ve answered my questions! 🙏🏻

[jesseyanke]

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

[davidschmidt]

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.

[kadebrady]

Could you guys do a sound comparison of the 64 and the 67 vs the stock sound?

[davncingilbert]

I have 2011 LML that was rebuilt with a CP3 conversion, and a stage 1 Garrett Powermax. At around 6000ft elevation, the drivability is nowhere near as good as the stock turbo was. Great for regular street driving, but boost/hp drop off significantly when the truck shifts into 4th/5th. If I don't back off the pedal, it also smokes like a freight train. I'm planning on going back to stock... SOON.

I have a 2007.5 6.7 Cummins should I go 64 or 67? Need to know since I’m gonna do it soon!

[masonpauls]

Great videos and thank you! Took the air horn off my new to me '07 5.9 to change the oil filter and realized the turbine on the stock turbo is really chewed up. Looks like something made its way through there, and I cant believe it didn't grenade. So based on your recommendations it sounds like going back with a stock turbo might be best for a stock engine, daily driver, occasional RV towing, and no smoke wanting truck...? Thanks for any insight and I need to give you guys a call.

[brentmcmahon]

I’ve got a stock 05 5.9 with only upgrade is a in tank lift pump and it works great and I have heard that a 64 mm tubo is what you need then I heard that a 62 mm is what you want and I am a week end hauler so which turbo do I need for my truck when my factory turbo heads south ?

[GTOGregory]

At what point should I worry about larger new injectors? Will the factory injectors suffice with the Stealth 64? I have a FASS 100 Signature Series lift pump and the Edge Tuner tune on a '15 LML.

[dansdiesel]

Hey y’all great video Like always never disappointed! I have a lmk with yalls built 750 trans could you talk about heat in built trans bc I live in Texas and would see 190f in traffic and the 83F out side.... thank y’all again!!!!

[wildvalve]

What's your take on 11balde compressor wheels vs others?
