the Vortec Max was a $900 option on your truck, and came with 50 more hp plus the trans and diff rated to handle the extra hp and torque to go beyond that. How come you didn't just do that out of curiousity?

Well since I wanted the single cab, the vortec max doesnt come as an option in my country (UAE), the only option available is the 5.3 L ..

I would go with a Power Adder. A Supercharger or a turbo. One or the other. But if you do get a supercharger make sure that you get a 8 rib pulley system (slippage issues) with superchargers and a big cooling system if summers are hot in UAE. The stock internals on the 5.3L will handle about 550 RWHP, also at the same time you need to go with supporting mods, intake, headers, and exhaust everything else you need will come with the power adder.

 

Once you do that i would look into a built tranny, I would suggest you go wtih the 4L80E conversion kit, a better driveshaft and some rear end gears.

 

If it matters to you all this would put you into the 12's.

Im done with the supporting mods, apart from the header which ill probably order with the supercharger. Then ill look into the built-in tranny i guess when im done.

And yeah, it does get real hot here in the summer approx 110 F

Id like to be running in the 12's, thats basically what id like to acheive with this car, i wouldnt mind taking it further aslong as it'll be reliable with the current engine components.

 

Thanks for the input.

Go Turbo.

 

Unless turbo is significantly better (performance gains, reliabilty.. etc), id still be going with the supercharger, well correct me if im doing the wrong thing. Well basically cause I think the supercharge is a "cleaner" setup than the turbo, in terms of installation and components that need to be addressed. This is based on my limited knowledge in this field lol.

Cleaner install, yes.

 

More power, no.

 

If you want big power, you have to go turbo or twin turbo. Which of those depends on what you desire. You need to spend some time reading up on the differences between the two choices (and supporting mods) before you order anything.

 

Here's a quick tidbit on parasitic loss which is one of the major downfalls of the supercharger.

actually the new Eaton TVS systems are supposed to be more efficiant then turbos. I would rather go with a Supercharger for power right of the bat i dont like for boost to build up.

STS turbo :D

I'm assuming you've already done the basic bolt ons, or are you just skipping this portion?

 

 

Yeah have them installed

-Corsa catback (Rear exit),

-Airaid Intake

-Chip Tuning (Yeah, will need to re-tune again)

 

Only thing im missing I guess is the Headers.

Umm hope this helps...

was about to ask for you to state your other mods. Well with what you already have, more affordable & simpler mods would be, fuel injectors, ignition ( MSD ignitions ). I would say supercharger, or the turbo. The turbo seems to do better but that whistle is too annoying to me, much prefer the sweet whine of the supercharger.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
