LLY / LBZ Mouthpiece Flow Data

Good Work, nice graph. It really puts things in perspective as to why you can't pull the hills at less than 230.

Unless you’re color blind…:tease

The added flow bench data with the modded MP would be interesting to see in comparison too.

What was the air box indicator showing? Anywhere near being correct?

great post and welcome man x1000000 on this being sticky

Great post man. Thanks again for another great contribution to an already strongly supported topic.

The air filter only had a couple of inches of water additional restriction. The Donaldson indicator doesn't trip until around 20-25 Inches of water, my filter wasn't that dirty. 25 In-H2O is almost 1 psig, that will certainly kill some power.

Great data. What a huge difference in airflows!

Question - can you get a KB modified 05 mouthpiece comparison with the LBZ one? I hope the modified 05 flow is up close to the LBZ, that's what I have in my truck.

Thanks again for the info.

If someone wants to loan me one to test I'll be happy to flow it and add it to the data.

I agree with this being a great post....After buying my Duramax a couple of months ago I found this site and realized within a few hours the LLY MP was junk. I did upgrade and noticed quite a bit of difference. Since then I've added a TCAI from Killer Bee. Not only does the truck run better, but the fan hardly engages even when towing....

is the orange line "LBZ/LLY modified" system the one killerbee makes or some other setup? and is the blue one (stock LBZ) that goes higher the best or, the orange one that goes second highest but over the higher test pressures better? I bought my truck last week and plan to buy whichever MP setup is better this week so ignore any stupidity, still learning the dmax ins 'n outs.

The highest bar is the LBZ mouthpiece only, the next highest shows how little drop there is when adding the rest of the intake for testing.

Thanks for the info. Its great to have actuall facts like killerbee has supporting these mods.
