I ran my 2003 Dodge Ram 1500 4x4 Hemi on the dyno. My numbers were 294 whp and 301 ft/lbs. These are the mods on the truck at the time of the dyno:

-Inertia Motorsports Spartan Camshaft with a 215/218 duration and 115 lsa
-6.1L Intake Pushrods and valve springs
-Longer forged exhaust pushrods
-Stacked Chips (my truck being an 03 means the predator does not raise the rev-limiter so the superchip is needed for the tcm)
-Superchip TCM Tune (6,500 rpm rev limit)
-Diablo Predator custom CMR (PCM) Tune
-180 Degree Thermostat
-TrueFlow XDi Extreme Intake
-Cat-Back Dual Exhaust
-35" Pro-Comp Tires

My truck has stock 3.55 gears as well. My truck is set at 6,500rpm for the rev limiter. Dyno was done on a mustang dyno where the rollers were loaded. I also did a 1/4 dyno run and ran a 15.3 at 91mph with the 35's.

Do you guys feel the numbers are low/average/high, and any input on how to increase those numbers would be great!

 

time to put more to the rear wheels.....sharadon tranny?? oh and ur 3.55's need to go. oughta go 4.56's.

 

-E fan 10 rwhp, there is one for sale in the classifieds 95 + shipping I believe
-Y pipe 10-15 rwhp 30 shipped from Jegs
-LT headers
-Torque Convertor
-New gears, if you are going to do NOS or F/I 4.10, if you are staying N/A 4.56
smaller tires
-Then I would look at Ported and Polished Heads
-If that still isn't enough go with NOS. I believe 100 shot does best on Hemis, higher than that there has been problems with the motor bogging down.

That should keep you busy for a while

 

TRM removal mod too since you have an 03

 

buy a sport bike if you want to go real fast. lol

 

Because I have the superchip TCM tune, do u think it is beneficial to do the TMR mod as well?

Also, I have a set of stock 17's and I will be putting DR's for the track on them. I would like to do gears but I love the Highway power (65mph+) that my truck has now.

 

Yes, Superchips doesn't do anything for TMR in an 03.

 

I may be wrong, but I didn't think from reading on here that a 4by could run 4.56 gears anyways, I thought the max was 4.10's.

 

I have seen 4x4 4.56 gear kits.

 

4x4 can run 4.56. they cant run 4.88. And I think 4.10 would be good gears. But do the cheap things I listed.
