16 sec quarter. Good/Bad???
ok... last weekend i cleaned the dust out of the intake (figure of speech)... :choochoo:
First we cut my intake box down by about 30% to allow more air when needed... Put the Superchips on Performance setting (highest setting), got out on the four lane road, came to a stop, and gunned it... From the data on the tuner, i ran a quarter mile in 16.1 sec at 87.1 mph from a dead stop... I guess i'm wondering if that is slow, fast, or good for the lack of mods... :humm: All i've been around is 1/8th mile tracks and have no comparisons to make... The truck details are below... And btw, this is a random run, i don't drive this way nor do i leave the truck on performance all the time... |
For a programmer that doesn't give a lot and a fairly stock truck running on 35's, 16 secs is pretty good. IMO
|
Thats pretty good. I've run 15.8 @ 84mph and spun the tires for the first 20ft. I was only running a 2005 GMC Duramax 2500HD SLT 4x4 CC/LB. PPE Xcellerator Standard Lvl 2, S&B Intake w/ Lbz turbo mp, Welded up EGR and Ported manifold, Pvc Reroute, MBRP Turbo Downpipe, MBRP Cat delete w/Banks cat back, Transgo Jr. w/ deep pan, XX Fuel Filter Kit, and 265 Toyo ATs.

I was running a 16.1 at 88mph on my QCLB Dodge with an Edge EZ and Jammer 100 hp injectors. 33" tires and a 6 speed. Considering what a DMAX is capable of with just a chip, 16 sec is pretty low sorry. With the automatic and a better chip and bigger turbo I run a 17.1 at 98 mph do to the factory torque Management. |
Thanks guys... My cousin has a 12 sec Mustang GT with spray and he was riding with me and said it was pretty fast... It seems slow to me, but then again i'm not on my R1 anymore... :s:

It's good for how "stock" the truck is but bad also because with some better tuning the truck can be an animal... Bud made 547 hp with alot of stock parts on in the motor.

Nice... I don't really want to mod too much under the hood without a rebuild on the tranny, so i've been holding off on the mods for a bit... My future goals are larger diameter injectors, airdog 150 pump, ATS tranny rebuild kit, maybe a larger diameter turbo for higher boosts, and loose the Superchips and replace with EFI live... I would like to see 13 seconds in the quarter with my diesel, but i want to load a goose neck trailer and haul it too... Guess i need to work a little more overtime :dang:
|
Not sure how to vote on here... :argh: But Id say thats not bad. I ran 16s with my truck and 35s". It was all stock at the time besides a programmer.

it just might be a one time thing though before the transmission decides to say eff this. you have tie rod sleeves on the truck? you could take off harder and cut down the 1/4 time by a significant number vs taking off with a straight dead stop. you can run efi with stock transmission, people do it all the time, and as far as upgrading injectors, better check and see if your stock injection pump can handle the stock ones with a 500hp tune on it first. and typically most people dont even upgrade them till after a turbo upgrade. Larger injectors do help out with a stock turbo regardless, decreasing timing and pulse width, but for the amount they cost you can still achieve the same power output with the stock turbo and the engine is still fine. for the size of the truck and, dead stop, and with the little mods u have thats a decent time |
All things considered, pretty decent.
|
So, where is this four-lane road that you can drag-race on? :td:
Just a though, if things go bad and you're lucky, they'll crush your little truck into a little college refrigerator. |
How are you launching the truck? Pretty slow for a d-max if you ask me, but the generic tuner isn't helping anything.
A lift pump, an EFI live tune, some tie rod sleeves and some trans reinforcement and you should be WAY under that. I ran a 14.25 with just an x-street tune (no converter lock up even) on 34" super swampers (weigh more than most 35" mud tires) with a passenger and a toolbox in the bed. That was with 100% stock exhaust (cat and muffler in place) and stock intake. That was with a boost launch in 4x4 though. On small tires and an x-race tune I could probably bust into 13's. |
I went 14.48 with a 1.90 60ft at a 4000ft elevation track. I launched about 7 psi in 4HI with 34.5 x 14.5 Toyos. That Edge wasn't near the programmer that my SCT is either. I too think 16.1 is a little slow, unless it was in 2HI with a smoke show.
Agreed, beef up your tie rods before doing anything else in that Duramax. I've seen hideous pigeon toe launches and I've seen them snap pulling a sled. |
Does the tune actually make that much difference? From around mid-low 16 sec quarter to mid 14 sec?
|
Old thread (I know, sry guys) I went from running 15.2** stock to a 13.9** with just a tune and a lift pump. So a tune will make a big difference. But truck weight, setup, and elevation are a big deal to.
