i'm sure both denny T and I made our pins the same way.

you look at the stock pin and then think what can I do to make this better,
a
then you get out all your measureing tools and see if its doable and how far you can go, then you test what you come up with.

 

Something like that.

But Im gona stop now befor this thread gets closed or I get a bad PM from a Mod

 

Not to bad mouth the DennyT pin, I don't have one but everyone that does loves it, but it pretty much looks to me like a straight ramp from no extra fueling to full fueling. It seems like it would be hard to NOT end up with something very close.

One thing I appreciate that Alwaysworking is doing is making several different profiles for the people that don't want all that extra fueling at lower manifold pressures! Where's Dennyt's version of that one?

Not to start any flame wars here, but my comment here might end up with a "really? That's pretty cool!", or a "Ya, Ya, right...another fuel pin wanna be...". But check this out:

A while back (Long while back, probably 4 years now) I won $200 from a raffle and used it towards a Smokey pin. After reading all the comments about pin grooving I decided to check my Smokey pin and sure enough, a groove. My sister in San Diego married a machinist proffessor at San Diego state college and 3 years ago they invested in a machine shop that an old timer was wanting to sell(retired). My bro in law decides to be a part time housemom and quits his teaching job and runs the machine shop part time. I sent him a hand sketch of a fuel pin that I conjured up. I did not want to go to the trouble of pulling out my Smokey so I used my stock pin along with my reloading micrometer tool and dimensioned out a pin with a radical slope, one more redical than the Smokey, but with enough meat at the thinnest point to not alow cracking. As it turns out, a whole year later(bro in law not as motivated as I wished he could have been) I get this pin in the mail. I asked him what type of stock material he used and it was stainless steel in its strongest form(can't remember the name or type). It came out sweet. I never put it in till about 3 months ago. Better response than Smokey. More power throughout the RPM band, and power comes on smooth and steady. Oh, yeah, did I mention no grooving whatsoever? The only thing I messed up on was the thread pitch on the top. I used a 1/4 20 thread instead of a 25mm thread.
I never knew what a Denny T pin looked like till someone a week or so ago posted an inquiry about looking at comparison pics of stock pins vs. Smokey pins vs. Denny T pins. As it turns out, mine looks exactly like the Denny T but with a deeper setting/slope at the thinnest point( based on looking at the pics, for all I know if I took measurements it could be close to Denny's).
The point I am trying to make is that I admire ambitious people trying to create their own, and not try so much to copy. Smokey had a great product but I would have never paid the $$ if I would have never won the $$. Smokey did invent the concept of the pin, and that alone should put him in the 1st gen Guinness book.
On the other hand, I am not too fond of copying for profit. That's just me and my opinion, though. Call it an ettiquete thing, I guess. I actually called my bro in law up to see if he would pump out around 6 more to GIVE out to my local DTR buddies that I met on this site that I share Saturdays with wrenching on our trucks, but my Bro in law is not responding. I might have to call sis to have her kick him in the you know what!

 

Heres the coolest part of all........

With the dirt floor, lean-to shop engineers we have on here we have managed, with a totally grass roots operation, to lower the cost of aftermarket goodies.....(ie fuel pins)

We all know here that we are often "praised" for being ol' school but often forgotten when it comes to aftermarket.

There are PILES AND PILES of threads on here devoted to sticking late model stuff on our early model rigs and folks are starting to notice the demand.

We're building air boxes out of pressure cookers, intakes out of muffler pipe and thats what makes us the "different" crowd at diesel meets......

With as limited as the aftermarket is........theres enough to go around......

 

one thing that makes me want to make tings for 1st gens is, when you call up almost any performance shop and ask them for a part then ask if they have it they say "well i can get it but i dont stock parts for that its too old, and you cant make any power out of 1st gens anyway without spending 20k, and no one wants to do that"

when someone tells you that, its makes you want to prove them wrong.

 

I had a guy at a shop where lots of you guys have bought stuff ( no name on purpose ) tell me that i did not need a fuel pressure gauge because I could not use all the fuel a stock lift pump could supply. They just do not have the experence with the first gens. We do not even show up on the radar screen.

 

When I tried to order a 3200 spring, one place told me it was a waste of time!

 

The local bosch shop around here, the owner asked if we would sell our 91. He said he loves the trucks becuase there so unhonored of what they can really do.

I mean you gotta give it up to guys like GLHS that can run a mid 13 1/4 mile time in a 7000# pound first gen with a 12mm VE. or c12h26 that ran a 13.8 in the 1/4 with stock tranny,stock injectors, and a stock turbo. Thats whats putting us on the radar little by little. Is proving second gen guys wrong and 3rd gen guys.

 

I had a "supposable" retired Cummins engineer tell me I was wasting my time with my ve project. All I was looking for was a ve pump core to fill the void where a pump was needed and he gave me the run around about the different motors and pumps etc.... Needless to say I didn't get anything from that conversation, not even a core pump that he was obviously too proud of.
Long story short I am with you guys and we need to keep the ve alive. Keep the backyard engineering alive! I believe in making as many parts as I can for my trucks. Competition is always a good thing.
I will be needing a fuel pin pretty soon for my stock 92.

 

these people who dont believe the VE will fuel at high rpms havent seen the marine VE powered diesels. The Volvo marine diesel is a 210hp 3.8L I6 that runs 4200rpms all day long on the water. Its got the exact same VE pump on it as we do. There is plenty of potential in them, and were the people who are going to find it.

 

that would be a pump to experiment with in a 1st gen. 210hp in "stock" form for that engine. exchange the 4200RPM spring for a 3200RPM spring (depending what you're plans are for the truck), tweak on the screws we all know and read about all day long on here and see what kind of numbers you can put down! talk about a resurrection

 

The only thing i would think y this wouldn't work is that its a 3.8L spinning 4200rpms vs 5.9L 3200rpms its probably making the hosepower in the upper rpms. I would also think that the 3.8L would put down lower torque numbers because of the lower volume of air its able to pump.

 

When I had my pump done I called east, west ,south.(no names given)all had an attitude about the VE.Dont get me wrong they would take my money but very short on details on pump .when I called Scheids they went way out of their way to explain the VE options .Went with the old smokey pin .Ive been very pleased but wonder if I should change pins now?

 

I'm in the market for a pin, just not sure if i want it before or after the hx40 downpipe?....
