went to the track on sat.

[Ieatpeople]

alright, heres how it went:
bone stock 2010 rclb 4.8l 4wd

60ft: 2.765
1/4: 17.48@82.44mph

why is my truck so slow? i previously ran a scion xb that went 16.7@78mph stock (when we ran he had intake, header, full exhaust), and from a slight roll i pulled 1 1/2 cars. i'm guessing the problem is my launch.

i tried launching fully stalled on the converter (1600-1700rpm), and it did a 2.9 60ft, i tried launching from idle, same result. then i tried a 1000rpm launch, and got my 2.765 60ft.

the truck is terribly slow off the line, with no wheelspin at all (traction control off). what can i do to improve this?


i do have alot of experience drag racing (made nearly 400 passes in the last 3 years) but only with manual trans cars. in my turbocharged tercel, i could get 1.9-2.0 60ft all day, and that was with alot of wheelspin. i don't expect my stock truck to get that low, but a 2.4-2.5 60ft would be nice.

[randeez]

tune and a stall converter would be a good start

[custm2500]

Take it back to the dealer and get a real motor! Why would you get the 4.8 if you ever wanted drive to the drag strip let alone down it?

Conveter is a great place to start, exhaust, intake, tune, and the only way to make decent times with the truck cam, nitrous, turbo, engine swap.

[Ieatpeople]

i know the truck won't be very fast when its stock, i just expected a little more out of it than that. 302hp/305tq should motivate it more than has been indicated thus far...

in my turbocharged tercel

I beg to differ. My 4.8 does very well, and there are many many others with the 4.8 that would beg to differ as well. He has a ton of torque management in the new truck. Get a custom tune and you will see a big difference, and a stall would surely help. What gears do you have, hopefully not 3.23s.

[custm2500]

But you 4.8 lovers have tons done to get respectable times.

You can get times out of a 4.8 but half the mods done you just start to meet up with a 6.0. You can make anything fast but why the hell buy a new truck and start at the bottom of the heap? One thing if buy something used and it is what you have to work with.

tons of mods, so a k&n,exhaust, and a tune with stock trans and 3.42s is tons of mods. runs mid 14s with an ext cab.

[custm2500]

Money is one thing that comes to mind. Some people want to see what they can do with what they have.

Money usually dictates almost everything, but to upgrade the the bigger V-8 would have been less money then intake, exhaust, and a tune. Then you are further ahead.

My point was why start at the bottom with a brand new truck, if you want it to be fast at all. Makes more sense financially, and time invested to upgrade the track factory. We aren't talking about something you picked up because it is what you could find, it is brand new truck.

Back on track with the thread, a converter would be your best bang for the buck. After that tune is a close second, then everything else mentioned will help you little by little.

[custm2500]

Mid 14s are respectable but gears, tune, and intake is a decent amount of money and a 5.3 should run that stock. Put those mods on the 5.3 and another few tenths faster. If he picked the truck up because is was the closest thing he could find I wouldn't see it so foolish to have the 4.8 in this situation. I think you keep forgetting this is a new truck. $10 more a month for the upgraded motor, or a few hundred at a time to upgrade the 4.8 and be 20+ hp behind.

plans for the truck include k&n intake, headers, exhaust, diablosport predator, plus a converter and shift kit. it doesn't have to be fast, just quick (14's are enough). i plan to buy something else for track duty.

i was just wondering if i missed anything...

[crossy's son]

Get a custom PCM tune from an online vendor like Blackbear (site sponsor), not a handheld.

i'll check them out.

[XLR8N]

You really can't beat a custom tune man. Also look into a transgo shift kit, a nice tranny cooler to extend tranny life, and a corvette servo. That and a nice exhaust system would be a nice set up.

[Ieatpeople]

the truck does have the factory auxiliary trans cooler, so i think i'm good there. shift kit was on the to-do list.

i'm wondering at what point is the warranty voided, converter?, shift kit?, headers?. any ideas there?
truck has less than 3k miles on it, so i would like to keep the warranty until at least 50k.

[XLR8N]

Is it the trans cooler built into the radiator? They say that one is not enough. I am not sure on transmission warranties. Maybe someone will chime in or you could call the dealership and ask. A custom tune would void it but you can get them to tune a spare pcm (will cost a little more) and you can swap in the factory one if ever need be.

No, a stock 5.3 wont run that. Yes, add the same mods and the 5.3 should be faster, but isnt always the case I have found. And I bought my truck brand new, I ended up with the 4.8 because I had a GM buyback from another vehicle, I had a certain dollar amount to spend on a new GM vehicle, and the 5.3 put it over the mark.It doesnt matter anyway, he has a 4.8 and thats what he is working with. I beat alot of people with mine, and they always think I am lying when I tell them its just a 4.8. Its not a bad motor, people who dont own it believe it is because it isnt the almighty "327". LOL.

Edit: just found your old post with your 6.0. Notice your times in case you forgot, 14.9. Your 6.0 isnt the be all end all motor.You had to add some nitrous to get the thing to run well, but now you talk about it like its the fastest thing out there stock.

its not about how big the motor is, its how you mod it. for instance, i know a guy with a carbed 305 that makes 420whp, i could build a similar setup for less than $2k and make more power, mostly due to fuel injection and some modern tuning. then i could turbocharge it and make nearly 700hp.

[Ieatpeople]

well i just ordered my predator, so we'll see how it does once that arrives.

[6789olds]

problem with the tunners is they dont remove the torque managment . since its fly by wire throttle when you floor it the computer brings the power in slow . the black bear also gives free tunes for life as you upgrade you truck . also a yank 2600 will help with your launch and you will need a bigger trans cooler then stock with the converter .

[Ieatpeople]

apparently it does give you the ability to modify the torque mangement settings, as well as just about everything else.

i got the tuner thursday night, attempted install, recieved an error message stating "calibration not supported". i wasn't able to contact them until sat. (they are only open mon-fri), and one of their employees emailed me a request for an original backup of the stock tune (you can download the stock tune from the truck to the tool, and store it on your computer), i sent them the file, and it turns out i have a newer calibration then they do, so they are using my file to make their newest update for the 2010 4.8l trucks. right now i'm waiting on a return email from them with the new calibration for my truck.

pretty good service even while nobodys at work, i'm impressed with diablosport so far.

[Outlawz2004]

Glad that you are happy with your diablo, but it cannot, I repeat cannot compete on the same level as a custom tune. You may be able to play a little with the settings, but it is nowhere near the same as a custom tune. Now you can get custom tunes downloaded onto handhelds now, but the mass produced programmer is going to play it safe in every area of the tune so the majority of the people out there dont blow up their engine. Your still going to get outran by custom tuned trucks with the same mods as you, and you paid more for the programmer than a custom tune would have been. But as long as your happy, we cant tell you anything otherwise.

[Ieatpeople]

thanks for the advice, i'll keep that in mind if i ever feel the need for more speed.

i have a couple of other project vehicles i'm working on right now, so other than an intake and exhaust, the truck won't see any other power mods for a while. (yes i am going to get the truck retuned once i get the i/e done, there's a shop just up the strreet from me that does predator tunes)

I am just glad you are actually using your own truck now and not a video you found on the internet. Forget corrected numbers, get the timeslip with that number and post it.I would still like to see a 1/4 mile run from that thing to see if it falls on its face the last half of the track or if it would actually get down in the low 14s. These are your numbers from dodetalk:

I have only made 3 runs with this cam at the track, two of which were 9.68 and a third at 9.76.....All were made in 3,600+ DA and correct to around 9.25 @ 77. The stock cam ran a 9.57 in 2,600ish DA. With the stock cam they were averaging around 9.7 @ 74 in 2,500-2,800 da (corrects to mid 9.30s fwiw).

Adding all 3 runs togather you see I ran roughly a 9.7 average in +800' DA.

[crossy's son]

my dad ran a 14.83 in the ole cummins with a 2.75 60' time due to bad bad traction...and i ran a 15.32 with a 2.82 60' i was a hard ass and let the clutch out too fast and spun like a bitch, shifting that thing is what makes our runs so inconsistent.

once i powershift to 5th and the turbo spools it's all over......:burn:

Post up the mph for the ole cummins. I bet it trapped fairly well with those numbers.

MPH gives a better estimate on power than ET.

91.2 MPH on the 14.83 run. that's pretty good with 100% traction and my dad driving it's probably capable of low-mid 14's. it's a good running old POS that gets 22mpg on the highway and will take almost any stockish performance car from a roll

WOW....Seriously you don't have anything better to do, do you....I posted from work off memory. I did not have the post on DT pulled up when I posted. I made 100s of passes in this truck, many in the 9.6s. 9.68 to 9.66....So what I was off by .02...and 100' da when I put it in the calculator. Thats a whole 1 tenth off on the corrected time. You can go to the track for a year of friday nights and might get 2-3 good nights with good air a year here, so yes I do believe in corrections. Corrections help paint the larger picture.

Yea...Just short of the 330' mark in 1st gear (I usually trap 330' around 56-57 mph, FWIW).

3.55s, 32" tall 20s, and 6,500 rpm, with a 3.00 first gear will do that for you.


You should have seen what 2nd prime was like for passing!!! I have it disabled now because it used the OD clutches and was a weaker gear in the 545RFE....2nd prime is an alternate 1.50:1 2nd gear ratio (opposed to a 1.68:1) used for high speed passing. I could nail it doing 70 mph and it wouldn't come out of 2nd prime until 105 mph.

[crossy's son]

Sounds complicated. Wouldn't want to be the guy who builds those trannies.

[Fast305]

Sounds complicated. Wouldn't want to be the guy who builds those trannies.

Not as bad as it seems.... The 545RFE started as the 45RFE in the 1999 Jeep. 4spd with alternante 2nd gear, making it a 5spd. In the early 2000's Mopar issued a TSB to reprogram many of the Jeeps, making it a 545RF4 5 spd giving the transmission a 2nd double OD. This program revision was in full swing by 2003. If you count the gear ratios the 5spd actually has 6 fwd gear ratios. Yet another ratio is locked in the program, but it is like a .45:1 OD that would never be practical to use in anything.

It is for all practical purposes dodges version of the 4L80E.

Oh really.....I don't have 17s and a set of bald ass M/T drag radials in stacked in my garage. Let me tell you, you really don't know the inside of my garage that well. They were there this afternoon while I was pulling apart a 305....To swap some Vortecs on.

Whos to say I don't have a set of M/T 295/45/R17s on order and on the way to me.:LOL: Who is to say I didn't order said drag radials when it slowed down at work this afternoon???

WOW...I cannot see the slip at work, but I ran mine last night for the first time in a good while.....I decided to go last minute and in street trim straight off the highway went 9.70 in 2,700 DA. Short belted it, pulled my dirty K&N out and went 9.58. Then pulled the tailgate and spare off. I let the engine cool off a little and ran a 9.43 @ 75 with like a 2.26s 60' time in 2,500 da. At that point I was wishing I had run on 17s, with my 4" track intake, and with no extra junk in the truck. I might have run really low 9s or even high 8s.

On a side note a completely bone stock 04 Hemi QC lined up against me and ran a 10.3x @ 68ish mph. I had a bolt-on 5.0 with a mild cam run a 10.00 @ 70ish next to me.
