M5 or Denny T???

[JD91]

about to order one... right now im runnin a heavily ground fuel pin and want to go with either the m5 or the denny t 2 just lookin for some opinions

Not going to gain anything with an aftermarket pin over your ground stock one.

Might notice a better "ramp" but no additional fuel.

I'd go with a M&H M3

[Black93]

I always thought an M5 and Denny T are pretty much the same. Wish I'd went with an M3.

[JD91]

Why the M3 over the m5?

[CumminsPower59]

Ramp profiles are different, M5 has a short ramp, while the M3 has a little bit longer ramp, so depending on how you have the starwheel, the M3 will take a little bit longer to get full fuel (still fast), as the M5 will go to full fuel with just a little movement.

All that shows is his pin may not have been ground enough. He didnt show his pin either unless i missed it. There are several guys running ground pins that are just as good if not better then the aftermarket. His idea of heavily ground may be far different then yours or ours.

Touché

Personally, anything with a shallow ramp profile for 1/2-3/4" of the total then a nice deep cut would be ideal for reserving the fuel until you get into boost. I noticed a ton better spool-up going from a DennyT 2 to a DennyT 1.

If you have ever been inside your pump and paid attention to how far it can move, you can get full fuel with a stock pin...... With imo not all that heavily modified. However, if the ramp is not correct with the starwheel adjustment it can create less on the dyno due to flooding, ect......

Point being is an aftermarket pin can be an advantage if the ramp is better than the custom pin. But no overall fuel will be had over a properly ground stock pin

I've been more than satisfied with my DennyT fuel cone and it would be one of the first modifications I'd do.

[RCCUMMINS89]

ALLOT of denny t pins will allow the slide pin to slide passed the o ring causing an afc leak. Not sure on the m&h.

I have ran ground stock ones, Denny T, and BD fuel pins.... Personally the BD pin performed the best in my truck (best ramp). I have never ran an M&H pin, but in the future if I buy another pin it would be an M&H stage 1, 2, or 3.

[peobryant]

I've been running the DennyT cone for years now and haven't had a leak, and I have a few buddies that have as well and haven't had leaks either. You're actually the first person I've heard mention that.

Rccummins is right.... if your getting FULL travel out stock pin.... adding a waste of money pin... will get you zero gains
