Anyone know what a stock 6.2 ( truck) is doing the quarter in?..I'm hearing 14.9 to 15.9. Thought the hemis were running high 15's already..before they bumped the horsepower up in the ram.

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.

high 13's low 14's :thumbs:

 

Edit:

Every time slip I've seen has been with 3.42 gears. I'd suspect that having 3.73's gears would get you a solid high 13's.

Best time I've netted so far with mine is a 14.6 at 96.3 mph. That's traction control off and the rear tires (factory Z71 18's) rolling in smoke for the first 20-30 feet. If I left the traction control on then yes, 15.8's easy. I'd love to get mine on a set of half bald Eagle LS's with some traction compound down in auto 4WD and see what it does. I'd be willing to bet if I could get it to hook instead of spin for half of the first 60' (60' times were HORRIBLE as you would guess, btw) it should pull down a good very high 13 or 14 flat time.

 

My buddies '11 Hemi/EX Cab/SB with factory 20's couldn't break into the 15's. 16.3 was his best.

I would say low 14's to mid 14's. Hemis are very high 15's and low 16's.

The L9H doesn't have AFM. Only the L99 does. He is however correct about the LS3 not having VVT or being E85 compatable.

 

 

Sorry for dragging this on... I recently bought a 2011 Sierra Denali. (L9H, right?) I was under the impression from all I had read that it has AFM. Was I incorrect? :confused: I hope so... I can do without the AFM, thank you. :)

Denali's got the L94 6.2 which DOES have AFM.

 

Thank you. I still wish I didn't have the AFM. :nonod:

My bad, my eyes jumped down a few lines in the engine application roster. L94's were for 6.2 utility applications only so a Sierra Denali 1500 series, should have the L9H not the L94.

Well I think that's really good news for me! I also agree with 11Silvy. I plan on a custom tune soon, and if I had the AFM, I would have planned to have it removed. Thanks, again.

Thanks for checking. Yep, my build sheet says L9H engine

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Dave's Auto (custom engine builder) tear down of L8T

      By No F-bdy Bs · Posted

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
