Dyno Proven HP/TQ: 205RWHP/230RWTQ
(Baseline w/o Nitrous or Supercharger - That's almost 250HP out of a 3.9L V6)
* Factory Specs are 175HP/225TQ at the CRANK *

I'm estimating over 320RWHP and 410RWTQ with the addition of the Supercharger and Nitrous. While the supercharger is already installed, no Dyno runs have been made yet with the Nitrous. Performance wise, it's just as fast as the old 60HP Nitrous shot (Dry) I was using earlier this year. Best time then was a 14.86 @ 94mph. The truck is already 2/10th's quicker than with the old nitrous system (and at only 6# boost). Once the bigger injectors are installed (30#) and the SAFC-II is tuned in for the Supercharger and Nitrous, it's highly possible that this 4000lb V6 Dakota will be hitting mid to high 13's in the 1/4 mile. Not too shabby for a daily driver that still gets 19-20mpg on the highway and is almost 3-seconds quicker than a stock V6 ClubCab (average 1/4 mile spec for a 3.9L Dakota is 17.0-17.4 @ 70-74mph).

Updates to the Dakota - February 3, 2004

We've decided to change the entire concept of the truck and removed the Supercharger and Nitrous system. Instead of trying to build the power for the 1/4 mile (which we've proven already)...it's time to get this truck moving at higher speeds. The suspension is in the process of being gone through as well as upgraded, along with a few new items. We're shooting for a 150mph V6 Dodge Dakota now.

We're calling it the "HS/E" (High Speed Edition). Custom PCM programming will be required as well as different gearing and tires to match. Brakes have already been upgraded with the rear disc conversion in the near future (no...not aftermarket either - we've got a few tricks up our sleeves). Most of the work will be done at the dealership in Austin, TX...so there are quite a few internal resources that we can use. We'll keep you posted of the progress.

April 3, 2004

We've acquired a set of 3.21:1 gears but will be holding off on the installation until the frame and suspension modifications have been completed. Suspension modifications include updated/slightly lower springs, shocks, and bushings...and frame modifications include reinforcements for body twist and updated (custom made) urethane cab/body mounts.

April 14, 2004

Installed the cab reinforcement bar as well as new ball joints (front lower). Suspension components ordered as well - urethane cab mounts, rear leaf bushings, and new leaf shackles. Next week...the truck gets another "drop" - 1" in front and 1" in rear. Once this is complete, it's on to the driveline.
