We have 95 octane over here

Only a moron would say that

Something IS wrong.Its not traction either so dont let some of these people try and pin it on that.Traction can be the difference between a 14.2 and a 13.8 but not the way your truck is running.The mph is way low.ya 2.2 stinks but your power is WAY off!

Actually i cannot think of anything other than your truck runnning with NO boost what so ever??????

With a 92 MPH trap speed, 4th gear is not an issue.

Humidity kills e/t more than heat, and who knows how well they prep the track down there.
Track prep will affect ET's, but will not significantly affect the trap speed on a stock L. Don's Bolt -- you know this. You probably just forgot that we all don't have sick-@ss drag trucks.

If you want to know how much HP you are laying down, look only to trap speed. ETs are affected by traction, driver skill, etc. At least for cars in the teens, trap speed is not.

see article here

92 MPH trap speed cannot be explained by environmental conditions or driver inexperience. There is definitely something wrong with the truck. Virtually every report of stock L trap speeds has been in the 99-101 MPH range.

On my first and only drag experience, a hot August day in Sacramento, my bone stock 02 did 100 MPH trap speeds consistently -- irrespective of ETs. In every 1/4 run I have done since then (in admittedly consistent SoCal weather), my GTech reports similarly consistent trap speeds, even though ETs can vary. And this has nothing whatsoever to do with my driving skills -- it's just wait for the yellow light, let off the brake, and stab the fast pedal. A trained monkey should be able to get 100 MPH trap speeds.

Do you have access to a chassis dyno in Aruba? That will give you another data point. If you show much below 350 rwHP, I would take it to the dealer.

How many runs did you make?? what was everyone else's times?? Was any other cars saying they were way to slow??

Could the Tree or the Track Timers of been faulty on that run?

Did you make more than one run??

As others have said, your MPH's are way too low, indicating a loss of horsepower.

Engine lacks power--possible causes:

1. Incorrect ignition timing(I doubt that?)
2. Faulty or incorrectly gapped plugs(shouldn't be that with your mileage?)
3. Air filter dirty(very well could be?)
4. Faulty ign. coils(doubt that or your eng would be misfiring)
5. Brakes binding(???)
6. Auto. trans. fluid level incorrect, causing slippage(???)
7. EGR system not functioning properly(???)
8. Use of sub-standard fuel(pinging???)
9. Vacuum leak(s) at hose connections or manifold(???)
10 Dirty or clogged fuel injectors(???)
11. Restricted exhaust system(doubt it???)



Something is wrong with your engine/controls, etc.

Low Trap Speeds Are Possible!

Gang:

Something is not quite right with our friend's truck, I agree. I don't think that it's possible to run 14.9@92 under any reasonable atmospheric condition with the throttle open the entire way down the quarter.

But...

Tim's assertion that every stock Lightning delivers trap speeds around 100 MPH is correct, but only under IDEAL conditions. For example, my stock 2000, which I regard as a pretty stout example, recorded a best of 13.79@99.7 in AWESOME air (50 degrees F, bone dry, high pressure...). This is typical, and I can guarantee you the the reported "bests" in the various signatures were also captured in good air.

I also have a stack of slips that were captured under very "interesting" conditions back in June 2000. The truck was BRAND new (300 miles on the clock), and BONE stock. Full weight, and a full fuel load. The temperature was around 90 degrees, low atmospheric pressure, and humidity right at 100% (occasional misting rain). This, friends, is the proverbial "worst-case scenario".

With power-braked launches and no wheelspin to speak of, I made several passes.

The 60-foot times were in the 2.1-2.3 range
Eighth-mile times ranged from 9.2-9.4 seconds
Eighth-mile speeds were between 76-77 MPH
Quarter-mile times ranged from 14.4-14.6 seconds
Quarter-mile speeds ranged from 94-95 MPH

The same truck in the same state of tune with no weight reduction or mods ran the 13.79/99.7 some 5 months later, so anything is possible.

Now, factor in that our frind was running the 1320 on AT LEAST 2 flat tires (16 PSI) and HE WAS CARRYING A PASSENGER (!), all of this in terrible air with presumed crappy track prep, 14.9 @ 93 is entirely possible.

If he has one minor mechanical problem or a poorly maintained ride (dirty air filter, clogged fuel filter, sludge in the crankcase, or whatever), this result is VERY possible.

Stock truck, flat tires, full weight plus a passenger, (heavy fuel load?), (not-so-great driving?), crappy wet air, (poor track prep?), and (slight mechanical issues?) will easily get you there.

As myself sated as well as others,There are serious issues keeping this truck so slow. I cannot tell you what is is because there is nothing i know of that would do such a thing if your intercoller is working. but i CAN tell you it is NOTHING of what some of these people are saying alone or in combination. Some of these guys are just throwing out things that effect modded lightnings by a good amount but not stock ones.If a certain lightning is gonna go 99mph in the quarter that it might be off as much as 1 mph but no more...........Unless you hit the brakes at the 60ft If i had to guess id have to say its somewhere in the computer or gigi put in some of her special relays

A friend of mine has an dodge dakota rt with a lot of mods and running 15.15 sec and running whith slicks
he told me that that a same year dakota whith the same mods is running in the U.S mid 14,s
