Just say no to the Tb spacer and shorty's like the above posters have stated. They are a total waste of money. get long tubes, a custom tune, and maybe a cai. That will put your truck into the mid to high 13's.

This is a video showing how the 6.2L sounds with headers and a corsa catback. The crew cab is my 6.2L, the 2005 extended cab is a 5.3L with a magnaflow muffler welded in.

All these claims of 6.2s smoking the competition but not 1 video.In 09 the only stats I can find is a test from some rag , and the 09 cc silverado beat the tundra by a tenth in the quarter.

 

No testing or videos can be found of the NHT 2010+trucks running the competition.Cant even find any good you tubes of 6.2s running hemis and tundras or ecoboosts,found one hemi video pulling a 3.42 truck thats it.The hemi owner claim stock

I cant imagine how.

Come on, lets see some media of all these claims of wins!

I agree on having lack of proof to back the claims of victory as it is hard to know when to keep a person handy in order to video or get pictures of these events. I look often on u-tube for some visual proof but yes not much is out there. I also notice there are not that many 6.2's out there either, I myself have plans to go to the track here in Houston so to be able to get actual proof and ASAP, I tried to record/video myself taking off on a 0-69 run and it was not easy holding the camera and at the same time producing a good safe run. So for now I have to live with the self gratification of knowing the victory possibilities my truck has and build from there.

Also thanks for the information on headers and TB mod's. This is one of the main reasons I have not added these yet, I wanted to get more feed back as ya'll have provided. I will wait until I have the $$$$.. and add Long tube ceramic header's and go from there.

Thanks, and Happpy New year.

What is entailed in getting a Black Bear tune?

And what has to be done to the 6.2L before getting it?

Corvette servo, CAI, etc?

 

:lurk:

 

HAPPY NEW YEAR!!!

Nothing needs to be done

 

There are multiple options (in person tune, rent the cords to record data, buy an autocal

What is this "Corvette servo" I hear spoken of? Where does it fit in on the powertrain and how does it affect performance?

The corvette servo goes into your transmission

 

It will firm up your shifts making almost zero slippage, if you want better than that you will need a stage 2 shift kit , that way you can chip through the gears and neck snapping shifts.

Don't know if you can put that into the newer trucks with the 6spd tranny.

vette servo holds the 2-4 band tighter in the 7004r-4l60e,no vette servo in the 6l80e in these newer 6sp auto trans trucks

what are top speeds that have been reached with or with out mods on your Chevy's 6.2 or ?. Mine recorded 139mph flat deserted 4 lane rd slight wind and before I let off. This was recorded on my navigation device's "highest speed" section as speedo only goes 120 mph. I know speeding is not legal but I was just overly curious that morning and it was a empty road.

Thanks for the info. This sounds like something my Son might like for his '07 'Hoe 4L60E. The 6L80E in my truck feels pretty good so far, but I haven't really gotten on it yet, as it has only clocked 1300 miles.

Def. worth doing in a 4L60e trans but if you want firmer shifts in the 6L80e, Blackbear is your friend. He set mine up perfect. :thumbs:

The more information I read here, the more I think a BB tune may be in my near future.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
