Let's hear about your #1stgenturtlerace! Tag me on KZbin or Instagram and comment your 0-60 time below!

[@1320fastback]

I'll have to give this a try on my '92 D250. She's a 5spd with a THD pin, HE351, 5x12 injectors and 4" diamond eye.

[@DuddiesAdventure]

Ive had a fuel pin and spring sitting in my tool box for years, and have never got around to installing it. Im still living that stock 160 Armadillo life haha. Great Episode Tim!

[@decentgarage]

Armadillo life 🤣

[@bbtoyshop]

Out it in and advance the pump and tune the pump and you will notice a diffence in perfomance and fuel MPG

[@FirstGenGod]

I like how gentle u are on the truck. I died inside when u said that u shouldn't floor them at a dead stop 😂 I was like...I've done that not all the time though I try to baby mine especially majority of the time.

[@decentgarage]

Haha, yeah I'm really gentle with mine for the most part.

[@patrickmoran8790]

On the stock fuel pin, there’s only about a 5 hp difference in power, not much in torque increase. Even with an aftermarket pin, in city traffic needing to make a left turn, loading up the transmission with like a power brake, can be beneficial to get there. Then add the next turbo or injectors. Instead of putting in the injector pump rotation in, buy and install the MH timing spacer. It gets you the timing advance at RPM without losing the bottom end torque.

[@drd1924]

The timing spacer didn't work for my truck for some reason? It started surging at high RPM like turbo chuffing. DO I need to add more of the washers to keep the spring preloaded more? The Denny T Pin definitely helped though with a more aggressive fuel curve

[@ericpatton7767]

Nice vid. Do you think that the gillett 60mm upgrade along with ddp stage 3 injectors would work well together?

[@decentgarage]

Seems like it would be a good setup. Best idea is to get i contact with Eric at the hungry diesel and get his recommendations. He's been around the block

[@10mm]

What a great idea for a video!

[@decentgarage]

Haha i could do a whole 0-60 series 😅

[@BabyJesus440]

3:30 someone went tractor flipping last night lol

[@decentgarage]

haha that's the local Mater!

[@paulandreassen9964]

Love the video.

[@decentgarage]

Thanks Paul 👍

[@ortizarmando094]

What kind of Automatic trans are you running on that OG Cummins? Trying to decide what I want in my 1992 D250 !

[@decentgarage]

It's the stock a518 which is a 3 speed with overdrive

[@KeystoneOutdoorsman]

Hmmm.. i may have to try this turtle challenge. I have a 727 3 speed so thatll be an interesting post.

[@jaded804]

So do I, how can I make this pig drivable on the freeway

[@decentgarage]

Governor spring was the best thing I did to make mine drivable on the freeway. Also taking the slop out of the throttle cable like i did in the last video

[@decentgarage]

Report back!

[@zachhensel5480]

Is that a slant6 or 318

[@KeystoneOutdoorsman]

@@zachhensel5480 5.9 Cummins non intercooled.

[@jimmungai1938]

What are the good things to do with the not just Chrysler torque flight or anything any of those transmissions is a good quality shift kit and for every day driving you don’t want that pressure turned up way way high like a sled puller just may be a little bit more than what I just shift kit requires too much line pressure is no good either this is six in a row jim have a nice day

[@decentgarage]

Yep, I've adjusted my line pressure slightly higher but that's it

[@nvboatguy]

Do you know how much you turned in the power screw, and by how much you turned out the smoke screw?

[@decentgarage]

Right now it's turned in 3 turns

[@decentgarage]

My smoke screw has not been touched. Still has the tamper proof cap on it

[@ebeegeebeefofeebee3181]

?

[@ebeegeebeefofeebee3181]

Waiting.

[@decentgarage]

@@ebeegeebeefofeebee3181 power screw is turned in 3 turns and smoke screw is untouched with the tamper proof cap still on it

[@noah-burkhardt7703]

Hey man dumb question and u prob wont respond but would this hurt anything on a stock everything 12v like the trans or anything?

[@decentgarage]

This is a great upgrade for a stock truck including the trans.

[@smokey4201489]

how many psi are you running on og crew cab

[@decentgarage]

Just under 30

Love it, I'm in

@@decentgarage I'll get a better vid but I tried🤣🤣🤣, that was fun!

[@keeprtuned]

Ahhhhh gotta do the 0-60 by the ole church parking lot haha

[@decentgarage]

Yup

[@hardhead7056]

Your backwards. Dont worry about 1st to 2nd shifts. Roll into it and Hammer on it. Needs torque converter rpms thats all. Thats the strongest 2 gears you have. "WHEN" it starts to go bad, youll loose reverse and everything else except 1st and 2nd. In the end, 1st is the last to go. Reving the motor in 1st.. It "may" limp around the property or to load on a trailer. Thats it.

[@decentgarage]

Agree to disagree. I'm looking at it from a fluid coupling of the torque converter standpoint. You're looking at it from the transmission itself 👍

[@hardhead7056]

@@decentgarage whats the difference? If in the end the transmission goes out. Low line pressure from low torque converter rpms. Thats the Achilles heel of the stock converter. Its originally designed for a gasoline motor. With torque peak in the higher rpms. Its a big reason the cummins smokes the transmission. To much torque combined with low revs. The worst thing about when people rebuild a old 518/519, i cant remember the model. Is that they dont replace/upgrade the torque converter. To one specific to the low rpm high torque cummins. Also making it a lock up style. Witch is another inherent flaw with the oem design. Aka, gasoline motor style torque converter. Simply, In its stock form.. If you use it like a truck, not a grocery getter. Its not going to last as long as it should.

[@TearlessGosling]

I would hate to see how my completely stock '92 d250 stacks up.

[@decentgarage]

Do it! Let us know your time

woould be tough, this is a quad cab swapped truck

@@decentgarage Sorry for the late reply, 16.08 seconds for my 92 d-250

27lbs of boost? on all stock besides pin?/ geez i might have a boost leak

[@decentgarage]

27 even seems a little low to me haha

[@Hatya05]

Wow, I believe mine to be all stock and I am only seeing around 13psi. I think ive got some work to do.

[@martinsinclair55]

No helmet and Nomex?

Unfortunately no

😂 industry secrets right there!

[@a-dog8075]

That's not fair! You have an automatic!😂 That fuel pin did quite a lot! What exactly is the use for the fuel pin?

[@OvensGarage]

Right. Not fair. I can't shift the getrag THAT fast. LOL

[@ericpatton7767]

@@OvensGarage at first I thought that my trans was messed up but after seeing everyone else complain about the getrag it made me understand lol.

@@ericpatton7767 Just got to feel the vibe of the transmission. Don't force anything, it'll go into gear when it wants to haha

[@decentgarage]

I can't believe my stock auto is still going strong.

[@OvensGarage]

@@decentgarage Before I swapped mine, the auto in my truck was okay when it was warm, but cold that thing slipped quite a bit. Someone put a BD diesel torque converter on it that I'm sure helped a bit.

[@avsorong3983]

More and more fuel consumption, not eficiency anymore

[@decentgarage]

It's honestly not that simple at all. It's fairly easy to have a 450 horse Ve pump that can still get 18 mpg. The key is matching fuel and air and more specifically matching your fuel curve to your boost curve.
