Well, Well, Well, Looks like I like to stir up contreversy so here it is...

 

[M4ck]

Looks like pretty good times to me. I am not familiar with the device though. Is it pretty accurate if so you should be able to hang with or beat most of the stock v8 trucks I believe. Good job there and keep up the good work. If you get to run it at the track make sure you post your time slips also.

Very contraversial evidentially whether the G-Tech is accurate.Nobody's posted proof either way yet. We will see...

I ran my G-Tech the other day and was getting about 15.2 at about 91. Those are my averages with 15.4 at 89 being the high, and 15.1 at 93 being the low.

I used to run the G-tech everytime I'd take my old car out to the dragstrip and 99% of the time it less than 1/10th of a second off and it was never more than 1.5 mph off.

Really, this is VERY,VERY notible This is what this discussion needs is people that haVe done side by side comparisons. Your times are EXACTLY what I got before my exhaust mod! Good job and ThanKs for the post!

So is the reason you pulled into a gas station after that timed run because you did it on a nearly empty fuel tank? Nice time. Maybe an email to the manufacturer of the device might get you some margin of error info.

LOL, I was at an eight of a tank. I'm allways at an eight of a tank, this thing will fly though gas milage shows it. I was so stoked over the times I pulled off the first chance I had so I could film the results worrying the screen would go blank or something. Running 90 plus again isn't something I wanted to do w/ out being at a remote location...

Here's the margin of error from manufacturer which seems consistant w/ Natel results...

"We look at accuracy in two different ways. First there is internal accuracy, which can be called resolution, and then there is Real Life Accuracy which is the worst case scenario to be expected in the measurments.

The difference between resolution and Real Life accuracy is the result of noise, temperature dependency, vibration and other elements that influence the accelerometer and other internal electronic circuitry.

Since the measurments can be anywhere between the best (Internal) and worst(Real Life) accuracy the importance of averaging results becomes even more evident."

1. 0 to 60 mph internal 1/100 sec Real life +/- 1/10 sec

2. 1/4 mile E.T internal 1/1000 sec. Real life +/- 1/10 sec

3.1/4 mile Speed internal .1 mph real life +/- 1 mph

4. Horsepower internal 1 HP real life +/- 3 HP

Real Life and the G-Tech/Pro

"G-Tech Pro measures time performance differently than the racetrack. It measures elaspsed time from the time you start moving rather than from the time the light turnes green or you cross the beam. This is better for tuning purposes because it eliminates driver variation in performance measurements and concentrates mainly on the vechiles performance.

additional, most race tracks average your speed at the last 60 feet of the 1/4 mile run while the G-Tech measures your speed at the EXACT 1/4 point.

So, some discrepancy is to be expected, however the cosistency of G-Tech pro is extremely good and optimized for baseline testing in "before and after" situations."

1/4 mile, and 0-60 times

Gentleman,
Very interesting indeed. I've little doubt that our trucks are capable of running those kinds of numbers. High 14's are mighty impressive as is the mph number. I'd still like to see a timeslip from a sanctioned drag strip though. With that thought in mind I'll mention that it is very interesting that in the HP/Torque wars between manufacturers they often tout figures...except imperical data like 0-60 and 1/4 mile times. We know that our Titans are capable of running rings around most domestic trucks in those categories. And on a final note every year at the Mile High Nationals mopar brings out their "hemi" trucks and runs them down the track. Two years ago the actual times were up on the board. High 17's here at altitude...which isn't bad on 100 degree day at 5800' elevation. This year they didn't post times, not even for that silly V-10 powered truck. It has power from here to tomorrow and does nice smoky burnouts, but I want to know how fast it went? My guess is somewhere in the high 14's at around 100+ mph. Which is an excellent number for a stock street vehicle here in Denver. And I am interested to know what kind of HP number the G-tech is suggesting?
Regards,
Sam

Sam,

Interesting,like your professionlism in which you post. I'll get a HP number from the G-Tech asap.

It's raining today so I'll have to lock em in as I'm interested in seeing what Mr.G will say...I really should wait until it's dry.
Interesting how it works as you have to input the weight of the vehicle your testing for HP and G-Force readings. I'm gonna input 5300lbs. Hope that's accurate. I weigh about 200lbs. Will keep everyone abreast.

Regards,
Finn

Ran the HP test on the G-Tech w/ 5300lbs. as the input weight and averaged a 270 HP reading at the rear wheels. I'll let you guys figure in what that equates to at the crank. Not sure of the formula off hand...

 

[Sr2]

Finn!

Finn,
I am eagerly awaiting your results. My guess would be somewhere in the neighborhood of 230-250 HP to the wheel. But we'll wait and see. My boss just got a brand new Dodge Ram 1500. It has the "hemi", and the bumble bee paint job. It is a pretty nice truck. I didn't have the heart to tell him that my Nissan is probably still quicker and perhaps faster than his. I guess a little race next spring is in order. Perhaps you know the answer to this question...do the 5.6 Nissan engines also have hemispherical combustion chambers? The reason I ask is that the spark plugs look like they run straight down into the top of the cylinder heads. As opposed to entering the heads "on the side" as one would expect on an engine that has a "traditional" in-line valve arrangement. Your guess on the weight of the truck is probably very close. In closing I am wondering what your launch technique is? Power brake up against the stall converter, or just go from idle. And were you manually shifting, or letting the tranny shift by itself? Talk to you soon.
Regards,
Sam
p.s.
am willing to bet that with a good exhaust, good intake, a chip, racing gasoline, and an experienced driver that a Titan is able to run into low 14's at around 100 MPH.

Sam,

As you can see my test w/ the G-Tech averaged 270HP at the rear wheels w/ input weight of 5300lbs...as I said I'll let you guy's convert it to crank HP.

I'm not positive on the hemispherical combustion chambers...

Launch technique is just smashing the pedal to the medal from idle in 4wd.
As far as the HP test I could see how this could give an inaccurate reading power brakeing up against the stall converter since in which the manner of how HP and G's are measured w/ the g-tech.

However w/ the 0 to 60 and 1/4 test this technique of Power brake up against the stall converter possible may yeild better times since weight is not factored and entered in this type of test allthough I have not tried this technique yet.

I let the Titan do the shifting for me, I love this drivetrain, how smooth and effortless the shift's are.

I have as well said and totally agree w/ you with a good exhaust, good intake, a chip, racing gasoline, and an experienced driver that a Titan will be able to run into low 14's at around 100 MPH.

Cheers,

Finn
