Lenny can you please go over lift pumps and lift pump pressure for 12vs Ive heard all sorts of numbers for pressure and im not sure where i should be with my project
With going smaller in injector hole size, is there any concern for damage to the p7100 plunger? When I first got into these 12vs (2007), I was always told going too small on the DV or the injector could result in pump damage due to excessive pressure. Never knew if that was true or just a rumor.
180 pump guy here can’t wait to see that video. Question. I got 181 DVs and got your stage 1s on the nozzle swap deal y’all did. Should I do the 024 DVs?
I have a 175 pump truck with a fass 140 gph. Just doing that, I felt a good increase in power. Maybe just had a worn out lift pump couldn’t tell you. Now I’m upping the line pressure with a tork tek 50 ofv. Excited to see what a 180 will do with 024s and ecos or stage 1s. Would be nice to hear your expectations of what the small cam flat top plunger pumps can do after your 180 pump testing. Thank you
I have your pilot hole stage 3s, 024 dvs and s362/68 with s475 and smaller 1.15 housing. Constant black smoke haze on the highway over 1800ish rpm. Turbos spool instant and make 65 psi pretty easy. My injectors too big? Do i need more timing? Im at 21 degrees. Stock 180 pump, ddp 3k springs, ddp afc spring. Looking to make similar power and minimal to no smoke. The highway haze is annoying
I got a 92 all stock ve with cranked pump and 4” exhaust made 430rwhp 1025tq with the 54lpm power jets and a 57mm s300g. Exact same settings but with an sxe364 and ddp4’s I made 450hp 1135tq. That is a lot more fuel and air for not much power. I wanted to try more timing but have to skip a tooth to test that and haven’t had the chance yet. Also I wanted to keep it like most basically tuned stock trucks so I have hard data I can give to people for modifying their own truck with basic bolt ons. The ddp4s run like 200deg less egt pulling heavy though where I am running like 30 psi for many minutes.
I am subscribed to you channel for a couple of months now. Not getting notices of new content. Weather permitting I am going to have my truck up and running soon. THD VE. (Not the race pump.) DAP 62/64 turbo. 3200 spring. Have the factory '93 injectors in it with the DDP Stage III nozzles in the box. I did jump a tooth when installing the VE. I am not familiar with DDP4's. Not seeing them listed. Are these some older injectors? Also is the Powerjet really DDP nozzles? I have a Carquest (Carter) 98.5 pump and in tank assembly that does 18psi.
So my 2yo stage 3s with pilot holes, 024s, 175 pump with 4ks, 024s, rack plug, #6 plate Attitude Adjuster, 63/67/12 HX35 (Ram Brake still intact). Made 540whp, 1153 ft-lbs 2 summers ago at Flying Wrench Services. Runs fairly clean but can certainly spike EGTs and makes 56 psi WOT with springate set as soft as possible. You guys going to do a trade in program eventually to upgrade older nozzle designs for this new stuff?
I have 2 sets of your Stage III nozzles. I took advantage of your sale of refurbishing my Bosch cores. THD IP have 4" exhaust to install 62/64 HX35 from DAP. At this point do you think what you are learning here will filter down to the VE trucks? I would be very interested in that.
You've got me wanting to upgrade injectors from my 5x.012s and DVs from my 181s to 024s
Can't wait to see where this goes.
Well if you need a stock 215 from a guy who's truck runs like crap I'm here local
Your videos make me want to go all out on my 12 valve in my 83 crewcab dodge.
No regrets
Lenny can you please go over lift pumps and lift pump pressure for 12vs Ive heard all sorts of numbers for pressure and im not sure where i should be with my project
looking forward to the next one!
Making 12v’s great again 🇺🇸
Keep up the great work guys amazing!!

Im curious how this plays into VE pumps where the fuel pressure is much more limited due to the seals in the pump.
This is awesome!!!!!! Keep it up!
Always great info!! Thanks!

So Lenny should I be looking to get the new nozzles on your stage 2 that I just bought few months ago

This is exciting.
Am I hearing you are going to use the piezo sensor for combustion analysis? That's going to be very interesting!
I think it was injection line pressure. Should be able to trace an injection event.

Can you get a p pump to make vp44 pressure so vp44 injectors work properly on p pump swaps

Timing is at 21.5° too
Soo, do I swap my stage 4s for stage 1 or 2?? On my 215 maxed and balanced 5k pump? Is that what your saying
Is there any 13mm plungers with timing helix?
I cant wait to send you some dt466 injectors
Sign me up 🔥💪
I will volunteer my truck to put the 180 in as I only have a 160
