I finally got my ram out to do a run with my G-Tech to get some rough numbers. I also did a run with an 09 chevy Impala 3.9L for comparison. I am not sure how accurate these G-Techs are so that is why I used a comparison vehicle. My truck is a 09 sport, 4x4, hemi, crew cab, with 20" wheels, 3.92 gears, 18" mufflex and a full tank of gas. The impala has a 3.9L engine, performance tires and a half tank of gas. The temp was 42 degrees at 2am on a flat, deserted stretch of highway. There was no notable tire spin for either vehicle.

0-60mph - RAM = 6.47sec, IMPALA = 7.57sec

1/4mile - RAM = 14.97 @ 89.0mph, IMPALA = 15.73 @ 89.5mph

0-60ft - RAM = 2.20sec, IMPALA = 2.37

Over all I was impressed at the bottom end acceleration of the Ram although the shift from 1-2 seemed a little soft. Could definitely feel the torque management. The Impala had no low end torque (a dog).

 

0-60 seems to be a little high as I have never been able to break 7seconds measuring with my trinity.

 

You forgot one, lol! How bout the Charger.........?

 

Ha, the Charger is waiting on a new carburetor, K-frame and rear axle housing. But unfortunately I keep spending my money on the RAM. I also want to build a 440 for the car and save the number matching 383.

 

Installed the Superchips yesterday. Set it to the 87 tune. took the truck back out to the same stretch of highway for another run. Air temp was 54* this time.

0-60mph RAM = 6.10sec

1/4mile RAM = 14.55 @ 94.2mph

0-60ft RAM = 2.20sec

I must say, as I have been reading about the 87 tune on the message boards I was not expecting that much. WOW, what a difference over stock. The shifts a nice and firm and could feel the horse power I paid for. The 0-60ft is the same I think due the wheel spin with the 87 tune when the stock run did not yield any spin. I cant wait to try the 93 tune.

 

Set it to the 93 tune. Same stretch of highway and air temp was 58*.

0-60mph RAM = 5.97sec

1/4mile RAM = 14.45 @ 94.1mph

0-60ft RAM = 2.15sec

The 93 tune seems to have a little more low end grunt than the 87. I launched in 2 wheel drive the same as in the 87 tune. It took me three runs to get these numbers because stupid me had the A/C on the first two runs. For those interested, with the A/C on the runs were 2 tenths slower in the 1/4. I will tinker with the trans options and do a run tonight.

Just a side note, the humidity was much higher this night that the night of the 87 tune run.

 

Those would be really good numbers if they're accurate. The best I could run at the track was 15.1 with my crew-cab and diablo 93 tune.

Yeah, I'm only trying to show the difference between the tunes not the actual numbers.

 

A little off subject buy my son has a fully restored 68 Charger RT. Nice car, built with a 400 cu in block with a 440 crank = 451 cu in putting out 525 hp. Its painted Charger Red, same color as it came off the assembly line. He totally restored this car and has had it 10 years now. His truck is a 08 Dodge Mega Cab 3500 HD 4x4 Cummings turbo diesel, etc - with a chip making 800 ft lbs of tq!!

 

I see. Well five tenths of a second is pretty good too!
