we dont need no stinkin fuel pins

 

sure, if ya wanna fork the cash for one of those nice shiny pieces.

I'd rather have AFC control though. I'm not a huge fan of smoke, and like to be able to tune it properly. A properly tuned truck will spool much faster than one with an afc delete top.

 

It doesn't smoke any more then a stage 2 untill I hammer down I drive her easy and its almost smoke free... And I got a killer deal on mine so much so I got mt grid delete from him To.

 

My right foot is the afc...

 

MOPARBUBBA id like to see that thing work with a set of BIG injectors in there.
Does it just eliminate the fuel pin???? why not just take it out then?

the m&h spacer idea would be a great way to stop low boost smoke and a longer fuel pin to accomodate the "Lift kit" the AFC got would be the ticket.

or
make a progressive dual or triple stage spring combined with a longer fuel pin and "taller" afc top.
or

i thought of having a "electrically" controlled afc.just pipe in a boost controller
no "full fuel" low boost issues anymore.
or even imagine a linear or even a screw type solenoid controlled by a boost controller
obviously a housing/mount would need to be machined.
100% contol over fuel delivery with a turn of the in cab controller..

But maybe without the initial fuel supply the turbo lag will increase.

i need a full fuel o psi very little fuel fuel till 30 then full fuel ..

wait a minute isnt that what the fuel pin is supposed to do


hell iam going to try it.
i need to order a wastegate for twin and the manual type boost controllers are not much money

wow what a ramble

 

Well with what I'm going to try with my pump is this:

Because I'm running big injectors, and smoke is ALWAYS an issue with big injectors under low or no boost conditions I'm going to make a longer fuel pin, which under a no boost situation should greatly decrease smoke. I'm hoping that it doesn't descrease it to the point of hampering spoolup. On the other hand all that smoke belching out also hampers spoolup. The point of properly tuning your AFC is to get the turbo(s) to light as efficiently as possible. Usually that means some smoke, but not a massive cloud.

Now this longer fuel pin means I need a deeper final point on the fuel cone. My stock ground pin won't achieve that. My plan (I think) is to order a DennyT stg 1 pin. I'm liking the profile it gives. I think it will suite my desires fairly well. I may need to alter the ramp a little, but well will see.

At this point I'm going to have a fuel pin 3mm longer than the factory one made and see what my results are. I have also done some very minor grinding on my AFC foot to make sure I achieve true full throttle. I figured out a way to grind it that won't really affect low boost fueling, but will allow further travel when a higher amnt of boost is achieved.

I've also machined the lip out of the AFC top so I have better control over the smoke screw adjustment.

I feel like I really should make my own thread on this and update as it happens.

EDIT:

Also who needs a boost fooler thingamabob when you could just go out and buy an adjustible boost elbow. It will essentially do the same thing. It will delay air getting to the AFC in an adjustible manner. Since that's the basic principle of what some of us try to achieve in cutting down the smoke and properly tuning our AFC.

Which gives me an idea... why don't I go buy one...

 

is the BD VE Fuel Pin & Governor Spring Kit a good one to have.

 

Mind sharing this method you found?

 

Depends on the price I have read that the BD might get a groove worn into it by the pin that rides on it. A dennyt pin is around $100 and a gov spring at a local store is only around $20 usually.

 

I should clarify that you do lose a little off the part of the foot to start, but turning to the shallow side of the cone should compensate enough, and you do get full afc travel with the shallow side of the pin if you cut it right, like mentioned earlier in this thread.

As for how you cut it. It's hard to explain without pics...you grind it with a crescent shape in the foot though... to put it as plainly as possible.

 

I am on the DennyT boat now!

My old pin (Stage 2) was bought last December by the previous owner. Had a bad miss in high rpm's out of nowhere. Long story short, wasn't the pin BUT I found out the pin was getting grooved badly.

I emailed Dennis and was told it would be warrantied regardless of who bought it. Instead of a 2, I got a stage 1 for less preboost power.

His stickers are going on my truck.

 

Im very happy with my Denny T stage 2 pin. And have heard if you grind the stock pin excessively it will go through the hardened portion of the pin and lead to excessive pin grooving. Is this true? Has anyone checked?

 

yes it wears but who cares

just take it out and check once a year

post up pics of your progress ...i also need to cure the low boost smokey blues

 

I ground the pin in my original pump back around 2008 or so, I had the pin out when I swapped on a new pump earlier this year and there are no signs of abnormal wear or grooving, YMMV.

 

because I'm running a longer fuel pin, I got myself a dennyt stage 1 cone. My afc is such that I can't get a normal pin back in ever. The length of the pin that I put in protrudes into the bore of where the cone is. but I still get full AFC travel with the dennyt1 cone/pin combo.

Yeah pictures are worth a 1000 words.

When I'm about ready to put it all back together is when I'll make my own thread, with a number of pictures to show what I've done and the results of what I've done, good or bad. I'm hoping my AFC mods coupled with the adjustible boost elbow reduces my smoke by a fair bit and can maximize spooling.

Things are taking so long to get done because I don't have a lot of money to work with nor do I have a truck to bring the motor to a shop for a reseal. I need to find a truck to borrow, so I can rent cherry picker for a day. etc etc.

I have all the parts including a cam to go in now too though. All the parts are there. All that's left is to bring the motor to the shop. And to make sure I have the money to pay the shop lol

And I'm with chris. I've ground multiple stock pins. Never had any noticeable galling or grooves.
