Default Going back to Atco with the hemi

Ran my sons 2012 ram 1500 Hemi rcsb with 4.56's and B&G tune on the stock tires it ran 13.73@99 2.000 60' last sat. I thought it was good for the mods.ran with some fast chevy trucks (friends from here) they both hit high elevens.

Going back tommarow with a short drag radial and try for a 13.50

Seen a bone stock last nite at the track here his best was a 10 flat in the 1/8 they are horribly slow. For the power it has its ridiculous. Dodge just can't get the power thru the trans.

I agree,even with 4.56's the gears seem like 3.73's because of the trans. Gearing.it has a 300 first gear and goes over the traps at 5000 in fourth.
To much tq. Management and not enough rpm's it only goes to 5800.
Bone stock with 3.21 gears it ran 14.58@95

Because when you add power and unleash the truck with reduced torque management this happens in a fairly short period of time.

The 45RFE base transmissions are HORRIBLE. It had invalid ratio codes for 4th and 5th gear and after I romped on it, all I had was 1st and 2nd.

Were you slipping off the line? I think thats a good time.

Anything that can run 13's with gears and tune only is impressive in my eyes. It would walk a SSS with the same mods I can tell you that much.

If i built it up of an idle it would spin.I dropped the tires down to 25 psi and just nailed it and it hooked

Who did the gear swap? I know with 4:56 the diff has to me machined for the gears for clearance issues.

Also ditch the BG tune. Put your 2011 computer back in it and get a CMR DIablo custom tune for it. Ive had both and the diablo is a much better solution for tuning
