The 14.0 was a superchips run on the street. I have a ton of 14.3-14.4 slips from the track in crappy Phoenix DA.
Oh and my truck was a 5200 lb 4 door
the best mod was long tube headers, no cats, dual 3" exhaust into 1 dual in dual out magnaflow glass pack with a built in X pipe. If I ever change anything on the G I will replace the stock mufflers with Magnaflows and remove the cats.
2nd best mod was 3.92 gears and limited slip
3rd best mod was the trans-go shift re-programmer kit and a 2800 stall billet Suncoast torque converter with a 1/2 volt .05 ohm resister soldered into the wire that returned line pressure to the ECU poor transmission spent its life chasing 120 psi.... probably ran at around 150 psi all the time. 180 psi + destroys the pump.
4th best mod superchips... raised the shift points to 6200 rpm and redline to 6500 rpm, had a performance mod... this mod gained .5 in the 1/4 mile on its own. Probably also killed the transmission and motor.
5th best mod, 6.1 hemi cam, manley titanium retainers and pushrods, manley steel valvesprings, 6.1 hemi wrinkle finished valve covers, 6.1 hemi coil packs, 6.1 hemi intake manifold. Typical rwhp gain was 60 ponies. The 6.1 cam works just fine with the 5.7 ECU.
6th best mod electric fan from 3.8l mercury sable wagon. Motor reved much quicker without the clutch fan. I ran a short belt that bi-passed the power steering pump at the track.
7th best mod ect ect ......
It was hard to let it go but it was broken almost every month. The last straw was a broken transmission and ring land on #3. My wife is awesome she shared a car with me for over a month while the Hemi was on wood blocks without a single complaint.
I had 2 nitrous kits installed one 75hp and one 125 hp. I only ever used the 75 hp and not even a complete bottle. I had problems with the throttle body puddling fuel.... probably don't have to explain why thats bad.
I ran at the track with nitrous once and ran a 14.7..... AF went to 16 and the motor was popping the whole way down the track. I killed it and pitted. Popped the hood and found a huge puddle of fuel under the throttle body!
I eventually got it to work by adding the 6.1 hemi car intake manifold but never used it at the track. I would guess from other Hemi's that 200 HP is good for about 1.5 seconds so I would probably have ran a 12.6-12.9 at the track on the bottle. When I sold the nitrous kits I parted it out and actually made money?
Your probably right about the only stock lighting... you are a pulley change away from low 13's.
