    My best before was a 13.2 @ 105mph with the 4.10's, and I only got that once. Tonight I ran consistent back to back 13.1's (3 times) and a 13.060 @ 108.99mph. The only mod changes were the 4.88 gears and I gutted the front cats (stock cans still there).

    Important: my 60' times with the 4.10s on street tires was 1.9's, but first was more tricky with street tires on the 4.88's, as you can see, even with a slower 60' time of 2.1 with the 4.88's, I still gained 2 tenths in the quarter and a couple miles er hour. I did manage to pull a 2.0 60' tonight with 4.88s on one of my 13.1 runs. With slicks these boys will be a beast!

    Also: Every run with the 4.88s it would shred first (id have to be easy) spin second, and chirp third AND fourth! It was kinda awesome hear 4th chirp every time, thank God for building us these trucks!!!! :rock:

    Also forgot, I had a Volant CAI with the scoop on my last runs, (with the 4.10's). Today was with stock intake (I sold the volant awhile back).

    Here's my new slips from tonight

    I would like to say thanks for " real information"!!! When you get hooked up, look out. I hope to see that truck pulling 1.7 60fts. Solid low 12s.

    Interesting....you had virtually no improvement in your 1/8th mile time...all of the gain was on the high end! Now get some drag radials and you will be deep in the 12's. Congrats.........it's fun huh!

    Throw a good 60' in there and low 12's will be yours. Nothing better than letting off the clutch and feeling that truck jerk forward!

    Good to hear that you are happy with your results. Looks like you picked up just over a tenth by gutting the cats. I'm a proponent of 4.88's for most people here. Lower gears will absolutely make a street truck more fun because they allow the engine to rev easier at partial throttle, during tip in, and especially at RPM across lower portion of the torque curve. In a WOT situation, like drag racing, our trucks build plenty of torque and horsepower, and the mathematical advantage gained with shorter gears barely exists. In other words, good air, and a plethora of other factors, will make a bigger difference in your E/T's than a 4.88 swap.

    Nice to see your results bro ! I'm sure it's more fun on the street for sure! Did you hit the rev limiter across the 1/4 laser?
    Spinning from a stop usually WILL gain a couple MPH and to get a true/accurate result you should have left cats, and air box as it was in prior baseline. Really hard to tell what helped and what hurt:dontknow:
    Can't wait to see slips with slicks though! I'm actually contemplating 4.10s in my QC to see if I can gain a little more MPH, MPG, and ET:rock:

    Thanks brotha, im sure a 1.7 60' wont be too difficult with some good drag radials :)


    I believe the lack of 1/8 mile gain was only because of the added spinning in first and second on street tires, and i also like to think that when i removed the volant and put the stock intake and stock filter back in that i lost a tenth. No matter what the numbers were, i had a blast, and enjoy this truck more than any vehicle ive ever had :rock:

    I went just before Christmas, it was about the same...never gets too cold here in sough Ga :mad:

    Jack launches at 5K rpm with his 4.88's!!! Bet that feels crazy in these truck :marchmellow:

    South Ga Motorsports Park, and my father and a friend helped me put the gears in

    Werent you one of the ones telling me that gutting my cats and leaving the stock cans empty "hurt" my performance?

    Dude its more fun on the street and track for sure, the look on these guys when it was chriping 4th! Haha and i had the volant before, and a dirty stock filter here, i know i was getting more air before.

    I thought from what other people were saying the 4.88 vs 4.10 were a night & day difference :dontknow:

    Huge difference on the steet, but to get all the good out of them at the track you'd need at least some drag radials. She ran way better at the track to me. Consistent 1-2 tenths even with extra spinning.

    I didnt have to change to 5th either. She redlines at 111mph with the 4.88's.

    There's this guy I know very well that just concluded R&D and testing on a NEW leverage bar system designed specifically for the SRT10 RC and QC!
    Could you believe a stock internal, Quad Cab with full interior and tailgate cuts mid 1.6s? :chain:

    Please Welcome Venomous1 Racing ;)
