Well they hold the power for about two or three runs and then have to dump 10 grand into fixing them. 😂. Yes of course I'm jealous but I'm just saying. I'd have to work another full-time job just for the repairs.
Hands down, the absolute best you tube video I've seen, the man doing the spec's is to the point and made sense, wish I had a teacher like that 36 years ago...
Looking good Lavon!!! How far you guys have come since i bought a transmission from you in 2013 is simply amazing! Keep pushing the limits! The knowledge videos are awesome! Good luck this year!
Thanks for sharing so much data. Were the air temp sensors the fast acting type? On the fuel only run, do you think 200f before the charge cooler is accurate at those boost levels? I know turbos have become far more efficient in recent times but it still sounds awfully low?
I believe they have 2 intercoolers and that reading is after the main cooler. Physics says 100deg compression in a single stage is going to be 700f+ even at 100% efficiency.
Just a thought… What’s the engineering idea behind the boost pipe coming into the manifold so oddly? Like most manifolds that style, the boost pipe would come in the front and have a “tapered” plenum. Where this comes in, blows the air into a wall then gets the the runners… probably better distribution, but terrible flow… 🤔
On the S10 we had a front entrance tapered intake and we seemed to get too much air to the back cylinders. We could maybe have fixed that with more of a taper, never really had a chance to try that. Some of the reason we went this route on the car was because of hood clearance but the idea was to make the air crash and disperse better. Definitely still a work in progress. Before we added the intercooler it seemed we were maybe overloading the center cylinders with air even with a deflector. Some of the reason for doing the intercooler in the intake was to help with equalizing air flow.
@@lynmiller8352 I always wondered how those front inlet tapered plenums didn’t just funnel all the air to the rear… evidently they do just that. lol. That’s why I asked. I assumed you guys wanted to have indirect airflow mainly to only pressurize the plenum rather than worry about the flow path and restriction. Makes sense and I love when people use their brains. You guys know your stuff… Nice job! 👍
On the fuel only run- 86 pounds of boost and pre-intercooler temp of only 207 degrees. What is cooling the charged air between the turbo outlet and the intercooler?
The pre intercooler temperature was measured 2 in before the intercooler core, then measured again right after the intercooler core, so turbo Outlet temperature cooled through 4 ft of titanium pipe before it reached the intercooler, I'm sure there was residual temperature drop from the cold air to water intercooler pre cooler
That's how the big and small cam Cummins work on injector pressure they would run a stiffer spring inside the pt pump for higher pressure and use the 178a 7 hole injector nozzles and retard the timing to 87* so you don't hurt the engine you can advance them to buy it wasn't easy cause you'd do it with the cam followers some of the small cams had multiple slotted cam gear but I understand what I'm talking about is mechanical and your stuff is electronical
Mind blowing how these guys make these engines hold so much power…. Nothing but respect

I never understood how timing worked but you explained it very well. Thanks for the video and congrats on the 3200hp
Thanks! 👍
Damn Lavon, that carnivore diet is doing wonders. Looking real healthy lately.
Thanks, it's become a way of life for me and i feel great
If the average person simply got off the sofa and pork you would be surprised at how healthy you can be not to mention 20 years more life span
@@MikeLJ-ku7ov Nothing wrong with wild pig or raise your own but the grocery store shit is poisonous with ractopamine in it.
@@FirepunkDieselGoing strong almost 1 year and will never look back!
Exactly lol. But diet can help to@@MikeLJ-ku7ov
Freaking wizardry with dinosaur juice hahaha. Congrats on the weight loss. I'm still trying.
thanks! its a daily decision!
Great video, Firepunk is the team that showed us its possible for a diesel to run with pro mods.
Love these kinds of videos
Really appreciate you taking your time and sharing this knowledge absolutely love it
Thanks
Dude!!! Thank you so much for explaining this so well! The diesel nerd in me was smiling the whole time at the whiteboard!
Thank you!
Thank you for the schooling on timing, Injector rates and back pressure numbers.
Looking good Lavon. This sport has come a long ways from cutting on a fuel plate with a dremil.
Yes it has !
Awesome video great info! I appreciate you guys for sharing it!
Thank you for explaining the timing. What an impressive drag car. Respect

Thank y’all for the awesome video 🙌🔥🔥
I’d love to see more videos like this! Really enjoyed seeing the in depth look into tuning!
Looking good Lavon!!! How far you guys have come since i bought a transmission from you in 2013 is simply amazing! Keep pushing the limits! The knowledge videos are awesome! Good luck this year!
Thanks!
Excellent information. I really enjoyed this video.. Thanks Lavon..
Awesome video, excellent info! Love this kind of stuff.
Keep up the good work Lavon, both with the car and yourself man. Crushing it!
Lavon my dude, lookin trimmed up . Keep up the good work, brotha
Seriously awesome content! I'd love to see more videos like this.
Love all the Data and explanations
I really enjoy learning from yall but my question now is, when does Firepunk tuning school start!? Consider this my letter of enrollment! 😁
Thank you for sharing Lavon!
Great work! Awesome information! Thank the crew for me🤘👍🫡
Need more content like this!!
What a beast!! Great info always love the knowledge!!
Great stuff!! Love the info!!! KEEP IT UP
holy intake runner, that thing huge.

Wish every diesel would run that clean, when making that power
more technical content please!!
EDIT: Lavon if you're a farmboy, I promise you 95% of engineers don't deserve their jobs.
Thank you Lavon. This is outstanding info.
Great work man you guys have come along. I’d sure have loved to see the power graphs between the runs. What rpm is peak power at?
That’s awesome information thank
Some really neat stuff.
Dynamite has a lot of great info about injectors on their UA-cam channel for those who love this tech
Great Video guys!!
This is good stuff right here. Looking good dude nice work!

🔥🔥🔥👏love the infos
Oh you guys maid the intake like the old small and big cam Cummins engine
The best in the business
5s bud .. we want 5s in the 1/4
How long do you have to wait between dyno runs at those power levels ?
30-45min, it usually takes that long to scan through the data and make a decision on changes for next pass
This is like shoving 100 lbs of dynamite into a 3 pound box then doing the math
That’s incredible
excellent info. thank you.
On the timing split, 85% fuel quantity BEFORE TDC? EDIT, I SEE, NEVERMIND 😊
Congratulations on a clean powerful "car"!
Did half of Lavon get up and walk out between this and the last video, Daym
From 252lbs Sept 25 to 179lbs this morning
AWESOME!!

wish i could get my 2017 6.7 tuned from you guys just too far of a drive being from canada lol
Amazing how the rpm range is 4 to 5k and thst powerband im mind blown
Is the afr ecm calculated, you calculated or y'all have a sensor that reads that lean?
What wideband are you guys using to read that lean of an afr? I can't find one that goes above 22:1.
What diet are you following?

And this is why you have cylinder pressure data logs 🤣

PT system is so different that most people dont understand how it actually works.
@@V8Lenny your absolutely right but I love it it's almost like the ve 12 valve pump but different
Are these corrected numbers ?
The weather station is on, so yes, usually runs half to 1% correction on a 50* winter/spring day at 800ft elevation.
@@FirepunkDiesel so no 25% altitude correction.
Does this car have a name? If not I vote for Coal Dust
Nitrous is overrated. Dinitrogen tetroxide is the way

why not just say 10000 HP so dumb
