21? That can't be right

 

I can't seem to find any real comparisons. Everyone talks about their 16 second HEMIs. I don't know if 21 is good or bad. It was reconded with my new SC Vivid LINQ. It accounted for tire size. It was set to 91 performance tune.

 

Last year I ran at 18.1 on a unprepped track with a bone stock (except for Air Raid CAI) 4.7L 5 spd...

 

Oh did you just floor it in drive the whole way? If so then 21 sounds about right

 

Is there any other way?

I found a country road and floored it for a quarter mile. Hit 89mph at the end of it. Seems pretty quick. This engine is completely rebuilt.

 

Did you ever put on the 2008 Intake Manifolds? I have a 2004 ram 4.7l and thinking of buying them. Haven't seen anyone actually talk good or bad about them.. Just wondering

 

I did not put the Intake Manifold on yet. I havn't had time to do any upgrades lately. In fact, one of my tires failed and I had to upgrade those instead .. LOL
I went from Falken Z04 S/T275/45/R20 to Yokohama Parada Spec-X 305/50/20




BTW: thats why I was able to get an 8.3s 0-60 ... and also why it took 21s to do a quarter mile. My Falkens were undersized at 28" tall.

I definately notice the reduction of bottom end torque with these new 'extra wide' tires. they are closer to stock at 31.5" tall.
