5.3 vs 6.2 drag race

TNTSierra · February 11, 2021

I’m not stating that ONE can or can’t run a 6.1secs like C&D did. I’m just stating the facts that the new T1 trucks are a second quicker than the previous generations. The proof is in the articles.

And your run of a 6.2L vs a 5.3L is about on par. The article states the 5.3 did quarter in 14.7. So C&D must not be wrong then??

Have you ran it with your Pulsar LT yet?? Curious if it helps. I’m still debating on one.

Yeah, I know they claim that outcome. But I question it, a lot. If I could get low 7’s in my 5.3L RST, I would be very happy. I don’t think I’ve seen anyone else run a 5.3L / A8 below 7.

Car And Driver always has the lowest times because they account for every single variable. This includes elevation, temperature, humidity etc. For ex. If they are above sea level for the test, calculations are performed to determine what impact it had on performance. They actually put a number to each and every variable and add, or subtract from the time.

They also run the vehicle in both directions and average it to account for any variation in the track, wind, driver etc. And last but not least they also allow 11.5 inches of rollout. Which will subtract .2-.3 from the time.

If you want an accurate time, data log it. Nothing will come closer.

But, you'll also be .3 slower then you thought you were

Your trucks will also slow down with mileage. Unless you tune it.

Why do you think you buy a new truck every 5 years. Feels old, slow, not what it used to be? Keeps repairs down and sells new trucks.

As far as GM is concerned it's their truck, not yours. You just paid for the right to use it.

On another note, intake/exhaust etc. does very little for acceleration times. If you want to actually be quicker look at a tune, e85, boost, engine work. Having an intake and full exhaust can help out any one of those mods (a bit). Without a tune it might make some power but it won't really make you any more quick.

Weight, suspension, tires etc. Not often improved for acceleration on a truck. But if done right, can have a significant impact.

Old thread, I know Came across it on google.

F' all the magazines and what they say. My 100% stock 2021 3.23 geared 4x4 crew cab short bed 6.2 RST ran a legit 13.61 at 101 at the track the old-fashioned way.

Wow, thats impressive! Considering the T1's fully loaded are actually heavier then the K2's. T1's have a larger overall wheel/tire diameter too dont they? Is There an extra shift with the 10 speed in the 1/4 or does it skip gears? What's your elevation, DA?

By the way, that was my point. Nobody is going to have the same times, to many variables

*Edit* Well yeah, your damn near sea level!

Pretty sure it ran through the gears and didn’t skip. And don’t know what gear it was in at the end. And yes DA was very low. I wasn’t planning on going to the track that day and had almost a full tank of gas.

You can think that an exhaust and CAI doesn’t help but @OnTheReel has numerical data stating he picked up 3 tenths of a second by adding them. I did it as well with my truck with the S&B and Corsa exhaust. So believe what you want but we have the numerical data that proves you wrong. And with a tune it would only make it run even better. I know my 2018 6.2L with 8 speed along with S&B and Gibson Catback Dual Sport exhaust before and after hand held Hypertech installed was night and day different than stock.
I am debating on the Diablo handheld here in the spring to get the full potential of my CAI and exhaust. It runs great now but if it helps my 2019 out like my 2018. Then I will be very pleased.

He didn't. Map is slightly higher (at high speed) with an after market air intake. But not 3 tenths worth.

The bottleneck isn't in the parts, it's in the tuning. For emissions and warranty reasons.

Headers > boost > engine work

Negative pressure > positive pressure > better breathing

A canned tune is basically increasing timing. If your truck falls within spec and you have enough octane, yep you'll make power. However, a lot of trucks miss out and don't work with the one size fits all tuning.

*Edit*

Numerical data? Good luck with that. There's to many variables and I doubt you or him did anything more then a couple passes.

What about the vehicles that made zero power increase, actually lost power, or made power but got slower?

Run a-b on a different day and you get completely different results.

All I know is my new 6.2L AT4 Sierra is a lot more spirited than my 5.3L Yukon. It would have to be a few car lengths at least in the 1/4 mile. It is also a few MPG less around town and that is me with an egg taped to the bottom of my foot when driving the truck.

TNTSierra · November 23, 2021

“@M1ck3y” He can think what he wants. If he has a 6.2L or 5.3L come on over and I’ll prove that a 6.2L with exhaust and S&B CAI will take a stock 6.2L. Oh wait I’ve done it!! But I’ll do it again just for $hits and giggles and to prove a point!

Plus, I also have a 5.3L in the family. My stepdad has a 2020 Sierra SLT 5.3L with 10 speed and it gets gapped considerably by my 6.2L, but his new 5.3L would gap my older 2016 and 2017 5.3L all day long. The K2s were “dogs” because of the lazy transmission programming in them.

Now, will both of those increase even more with a tune….absolutely! Which is why I did it with my 2018 and will do it in the spring with my 2019. Don’t have time to let my truck sit for a week while ECU is sent out.

I couldn't give 2 $hits about which one is faster in a drag race, I didn't buy my truck to drag race and could care a less.

KARNUT · November 23, 2021

Most of the time since I started driving I would trade for the next one because of HP increases. Every truck I did mods to increase power up to supercharging. All had tunes of some kind. Finally my 2014 was the one that I only tuned the transmission. I was finally satisfied. Of course I was 58. That may have had something to do with it.

Think what I want?

Are you under the impression that I came up with this conclusion? If you are, your wrong. I am not an experienced racer, tuner etc. But I've have talked with people that fall into this category. The internet is full of people that know what they're talking about as well, but you need the ability to sift through the bull ******. And you sir, do not know what your talking about.

Why are you talking about tunes? I said tunes are good!

Don't get your panties in a twist, take a deep breath, relax... These facts don't make your truck any less cool.

And if I'm being completely honest here, if you think you made horsepower with an air intake/exhaust (which you probably did). Acceleration improvements likely occured because your more confident, you think you have an edge, and you think it make's you faster. Therefore you are faster

Again. My panties are not in a “twist”. I’m just stating what I’ve done. So I do know what I’m talking about if I’ve done it. You obviously don’t. I can and have the data that shows it is faster along with racing a few here and there. You just “keep” talking to people. I’ll take care of the real world stuff. Sounds to me “if I’m being honest “ your confidence is lacking and you don’t have the “balls” maybe too try it out??

I also offered to prove it to you just for $hits and giggles. And I’d love to see the look on your face .

As for tunes. I was and have stated from my first post that they are GOOD. Just that with an exhaust and CAI they would be even better. Maybe you didn’t comprehend that?? It’s ok. It takes u a bit to catch up. We obviously can see that!!

as for @Silverado 4x4. I could care less if you like to drag race or not. Many do! Everyone is different. Thank god we aren’t all boring.

Enjoy your Thanksgiving peaches

Good day!!
