If you're looking into getting a fuel pin and want to see what they can do, I'm posting some good stuff to watch. M&H Inc is one of our sponsors and have a selection of profiles that allow you to tune your truck to your liking.

Also Here is a DennyT vid, because it too, is a great pin.

1991.5 1st genny 2 turns on the pump, 3200 rpm spring, hx35w n 12cm housing, silencer ring MIA 4" expandit exh, 4" skyjacker lift 35" mud terrains slowly making more power!!!

Duh. I'm on it.

Definitely one of the first mods I do when I get one

FRadisi's Sig:

1991 D350 - Intercooled, Getrag, regular cab, flatbed
Mods - BHAF, 3 turns on the smoke screw (but no smoke?)

I coppied the info on each run and I am confused by the numbers made by the stock pin?? must be an error.

Also, notice that the highest numbers made were by the M3 pin, not the M5.

I bet it has to do with over fueling down low.

Ok, so all of the M&H pins have the same profile @ the deepest point, the different pins are different because of the way they move into the deep part of the pin. A different shaped lip, so to speak. Then it seems that the M3 would probably be the best all around fuel pin because, there is less wasted fuel @ lower boost, and it just moves into full fueling in a more efficent manner.

Yep, and that is why I will be running a M3 next year pulling.

alright so what would u guys think, should i ditch my bully dog and get the m&h pin or should i stay with the BD.

Also muskrat what was the next best pin, hp wise.

Never mind its the m4
sorry

Your BD pin is essentialy the same as the M5 pin. So, looking at all those videos as a test - a mostly stock truck, no variables, the same dyno, just a swap of fuel pins, it shows that the M3 pin makes the most power, period. As the profile gets more agressive, the less efficient it becomes, because the rack is basicly just dropping into the fullest fueling point(the deepest part of the pin), dumping fuel in that won't burn (because of low boost), rather than moving in a more efficient path. Utilizing more burnt fuel versus sending unburnt fuel out the pipes. Thats how I'm seeing it.

stock numbers have gotta be off... i thought these old girls came with roughly 185 horse to start with?

One thing i learned in college: DON'T!!! stick your fingers where you wouldn't stick Mr. Happy 89' W250, full fuel 1 1/2 turns, smoke screw needs adjustment, M&H M3 fuel pin and timing spacer, 366 spring, air dog 150,3" DP to 4" DP back bully dog exhaust with the front baffle cut out. Soon to be:transmission upgade, turbo and manifold swap, and injectors.

Yep, it has to be a misprint. They should be around 160 hp. My 85 4runner has more than hp than what the first vid shows

A stock cooled truck with a rag should be upper 140's lower 150's. A stock non cooled truck with a rag should be maybe 5 hp above that.

Richie O's Sig:

89 Dodge W250, auto, 3.07 factory l/s, 4 inch stans exhaust, S300G 57/64/14, powerstroke intercooler 297 HP. 93 W250 extended cab, rag, 4.10 l/s , 6x16's, 60mm GDS H1C with 16 cm exhaust, work in progress.301 HP

yeah a little confused of the first dyno run hp and tq, i know my truck was gutless stock,but cummins is normally close to the hp they say the engine is rated at, i think my buddies 4 banger jeep has more then 78hp
