 Subject: My 5393 Pound QC and 0-60 Times
IP: Logged
Message:
From G-TECH Pro, adding up the weight of my 2001 4.7 Q/C with me, my son, rear cover, and full tank of gas, and inputed a whopping 5393 pounds for weight.
Had a 35 degree day with some head wind, not the best conditions re: weight and weather. One run:
0-60 in 7.02 seconds
1/4 mile at 15.57 seconds/89.4 MPH
Not too bad, I know I need to lose my son and a bunch of gas for the next runs...with my auto, is it better to power brake to say 3000 RPMs and go, or just take off by flooring it?
BTW, I have Auto/AWD/3.92/LS/T&H and bolt on mods.
What are some other Q/C with Auto times?

Woh! No way, you would be having to push 320-360hp at the crank to be doing 0-60 in 7 seconds with a 5400lb beast.

That is what the numbers were shown on the G-Tech
Pro.
As a matter of fact, I don't think the weight was needed for the 0-60 and 1/4 mile times but is needed for Rear Wheel HP which I didn't monitor.
I'd say I'm at 300+ HP (not rear wheel) with my mods (never said the truck was stock)

Not to be critical MACE, but I doubt your running mid 15's even with those mods, most likely mid 16's. I have the same mods excluding the jet II and my best was low 15's. You should go to the track to get some real numbers.

Mace, what size tires are you running and what altitude are you at? Also what is the rubber flap removed that you said in your list of mods? I don't run anywhere near those times, but I have 31" tires and race at 6000 ft.

I'd believe the g-tech times. The key there is the weather, which was not bad but excellent. 35 degrees and you would have no traction problems with 4wd. This morning on the way to work it was 6 degrees out, the streets are bone dry like the air at that temp. and my R/T has never run stronger. Even with 500 pounds of sand in the back it barks the tires good on the shift to 2nd and my R/T is bone stock.

Horbedarn, the rubber flap is beside your rad, it allows better access to cold air for the intake with it removed.
I got absolutely SMOKED by an R/T on the highway yesterday, his tailights were distant on the horizon with no hope of catching him. Course, it would probably help if I wasn't such a chicken.

It sounds like you have broken in the 4.10s. How do you like them?
How much performance difference did you notice?
Have you had a chance to compare MPG?
Do they make more noise than the OEM gears?
Thanks,
Bill

Dakaty,
I like the new gears alot, it did cause a good noticeable change in performance, but not as drastic as i was hoping for, but i had 3.90's to begin with, but the window sticker and glove box stated 3.55's, so if your going from 3.55 to 4.10 i am sure it will be a HUGE difference in performance. i am still learning how to launch with them. man, it sure does light the tires up at WOT.
i havent really had a chance to monitor the mpg change, to be honest with you, it really doesnt matter to me.
the gears do have a very slight whine to them, but not bad at all, i only notice it on the freeway, no complaints at all! my only problem right now is my gas pedal vibrating my foot to sleep for some reason.....still trying to figure that out.

Did the vibration start at the time of the gear change?
If so, maybe they re installed the drive shaft a half turn off at the rear end. I've heard this will sometimes cause a vibration.

the vibration is not related to the gears. i noticed it after i installed my new TB 70mm. i have had no problems at all with the gears or installation of them.

MACE, I hope you are not doing any kind of acceleration runs with a baby in your truck. I hope your son is not young, otherwise that would be foolish. I have done some pretty crazy things in cars in the past and I wouldn't wish that anybody else was there. Its one thing to endanger your own life, but quite another to put that on a passenger. Just keep in mind that many people get injured or killed in every day legal speed driving. Pushing cars to the limit should not be done with a passenger. Besides, you'll be faster all by yourself.

You've got the 70mm tb ane 4" tube and the best you can get is low 15's? Stock you should be pulling high 14's.

Your right Dr. Q. I should be pulling high 14's. The last time i ran down the track was with my old 215/75's and I had terrible traction problems and I feel I could still improve my launches and shifting. I dont have the 3.92 gears which kinda hurts me some as well. Since then I got a full 3" exhaust, lakewood traction bars, and new 15x8 rims with 255/65r15's. Bad thing is I have to wait till mid -late January to get back to the track to see. PEACE!

MACE is on the right track with the g-tech. At first I got it to compare and track the improvement mods made. What DID learn was that half the battle is learning how to drive! I thought it was just pop the clutch and floor it---BIB mistake. You'd be surprised just how subtle changes can improve your results.
Hey Kicker, How about you get the 3.92 and I get the LSD.
Anywasys its all pipe dreams now at least til the snow melts!

Sorry for not replying back to ya all, was on vacation when I started the post, was checking email from work, haven't been on since:
KLC - Yes, I noticed the vibration in the gas pedal after the 70mm TB was installed. You ain't gonna believe this, but it went away after replacing a bad RS 180 T-Stat (truck was never warming up past 178 degrees after 20 minutes of run time, thus promoting a 1281 MIL)...go figure!
Grady C - agree, foolish to have young-uns in the truck doing stuff like this...my son is 14 years old, 6 feet tall and weighs 170 pounds...believe me, I tried to get him out of the truck during the run, but he wouldn't budge.
Horbedarn: I have the 31 inch tires from the T&H package, with 3.92 rear. Altitude could only be a couple hundred feet, 35 degrees out, no humidity at all. As mentioned, the tires had 40 PSI of air pressure. BTW, O/D was turned off.
DR Q: I know you have quite a few run with your G-Tech Pro with some nice numbers, seems you have the 'launch sequence' down pretty good...thoughts on doing this with a automatic and AWD (full traction, never any wheel spin!)...powerbrake to at least 3000 RPM and release the brake and floor it, or just floor it from idle?
BTW, I think I'm pretty close to guesstimating 300 HP with the mods, thinking no two engines are alike from the factory and DC understates stock HP. That day's weather was also a plus.
Now looking for multiple runs (without the son) and running with less then 1/4 tank of gas.

SON OF A _____! now i am REALLY confused. your gas pedal vibration went away after replacing your t-stat? how in the hell is that? dont get me wrong, im not saying that your wrong at all, but i am just trying to figure out how the t-stat relates to the throttle??? so, do you recommend that i change my t-stat to cure the vibration?
thanks for the info.

KLc: confusing as hell, no?
Only remote thought I could give is that the engine temp never got up to normal operating temp...actually the truck now seems to run just a tad bit warmer than when the first 180 T-stat was working ok....I also had a squeal when hitting the throttle or when the auto tranny was shifting, that also went away...perhaps the increased operating temp of the engine had something to do with fixing the problem...I'm only guessing.
Keep in mind I had a legit T-stat problem, I wouldn't replace your's if you don't have to...how about WD40 the hell out of all your TB cables?
Good luck, let us know what fixes the problem

confusing is an under-statement. i tried the wd-40 idea, but it didnt work. i even tried adjusting the cable to see if i noticed anything at all. the only other idea that i have is to check and make real sure that the butterfly valve is not loose. i am also going to take the z-tube off and run the truck around the block with out it, just to eliminate z-tube being the problem. i know it is not good to run without a filter, but im sure just around the block will be ok. if any other ideas come to mind, please let me know.

Do you have the 4 inch z-tube and/or installed it the same time as the 70mm TB? Perhaps the increased air flow plus the bigger TB is causing some kind of resonating condition to the mouth of the new TB that manifests a vibration that you feel in the gas pedal? But then again, you would think we'd hear more complaints about this????

yeah, i have the 4 inch z-tube. that is exactly what i was thinking. it kinda feels like it needs a dampener of some type. maybe i should try attaching some kind of weight to the throttle assembly......hell, i dont know, i am just aggrivated with it, i am thinking of doing what someone else suggested.......just wear thicker socks....lol

DR Q:
I totally went against my engineering background and did modifications and upgrades without getting stats from the 'static' configuration to compare against the 'test' config, after significant run time.
Besides, I didn't find out about the G-Tech Pro till after all the mods were complete.
I know I can shave about 360 pounds off that weight without my son and a full tank of gas...just gotta do another run on the same road and type of day (weather wise) for a consistent comparison...when that happens, I'll post the results.

My truck has the same vibration in the gas pedal. Before the 72mm TB, the 4" Z-Tube, and headers I was running around 17.8 in the 1/4 mile. I know my truck weighs 4700 lbs, has 31" tires, 3.55 gears, and I am running at 6000 ft. above sea level but my truck is slow compaired to what others are saying. Has there been any problems with the cams not being set right or so other problems.
