I've heard of bone stock tucks putting down 160hp at the wheels, the numbers in teh stock video have to be wrong.

I saw a 90 non cooled truck put down 166 but he had turned the fuel cone to deepest. Rest was stock.

That low hp stock doesn't seem right to me...

and the torque is way to low 140 ft lbs of torque and they're rated at 400 ft lbs. Somethings not right.

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.

Yea thats true, but i still think i'm going with the m3 pin and will give my PA the BD.

The numbers on the videos are what came up for the dyno pulls, the guy running the dyno didn't think they should be so low but, we ran the dyno the same for the white truck and it made good power.

I think also to remember there is tuning that can be done for each level of pin to make it better, the M5 was probably over fueling on the bottom end which can be somewhat fixed with smoke screw/star wheel adjustments.

guessing these tests were done with no adjustments of anything other than a pin change.

so does this mean that the Denny T pin must over fuel also since it is cut pretty deep also?

**muskrat** · #23 11-30-2009, 04:26 PM

I think it does to a certain extent, but as Budgreen stated, you can tune your AFC to help with that. The M&H pins all have the same profile, which is relitivley the same a a dennyt pin, they just vary on how they enter into the deep part. And mind you, it is only on the bottom end, that it is over fueling. I think that really only affects you if you're competitive in pulling or racing, where a few feet on a pull, or a second off your time will make or break you.

so with a denny T pin and my pump mods, how should i tune it to improve the bottom end? im not worried about smoke at all but the faster the better!

**muskrat** · #25 11-30-2009, 04:46 PM

I think all of the adjusting is in the AFC. When I put my M4 pin in I had the smoke screw in flush with the lock nut (2 turns) and no star wheel adjustment. RSWORDS suggested moving the smoke screw back out to help spool up. I tried that and it helped, but I ended up giving the star wheel a full turn and keeping the smoke screw at one turn and that is where I'm at now. And I like it. Just play with it untill everything feels right.

At a point, yes. for most people, it will be fine. I was very happy with my DennyT (and still am) but with the addition of the 6x16's and some of the other fuel mods it fuels way to hard down low. As was said earlier, you can tune alot of the heavy fuel down low out, I have the star wheel and smoke screw all the way up and that helped but It will still over fuel the turbo and put the fire out. I will be getting a M3 from M&H this winter and giving that a try to see if it helps out any.

With the DennyT my truck is a dog if I just mat it. All it does is smoke like a freight train and lug along untill it finally lights the turbo. Once it does hold on though! If I roll into teh throttle the truck is alot quicker!

Again, I'm running alot of fuel. Didn't have that problem untill I put teh 6x16's in and re-indexed and ground the throttle level for more swing and fuel.

TTipsword · #28 11-30-2009, 05:53 PM

ya my truck is the same way. probably not to the same extent as yours but if i floor it it just putts along and smokes with terrible turbo lag. i will try backin the star wheel all the way up.
