So when one finally decided to say it's time for a Supercharger, what exacly is on the list of parts you need to buy? Complete list please...

 

Are there mods that have to be done to existing parts? Or is it just simple plug and play?

 

Most important, most recommended SC? Pro's and cons also?

Well it just depends on how much boost you want to run.3-4lbs max boost you probibly will be ok with just a bolt on. but you will still need to retard your timing to about 28 degrees max and use 93 octane. (you want to prevent any pre dedination since your compression is a tad high). But I will asure you once you feel the the boost you will want more... Its only natural!!! So for some food for thought you should build the motor to withstand the extra pressure.. For starters I would drop the cr down from 9.6:1 to 7.5:1 using forged pistons and rings designed for blower apps. Connected to some forged rods and a forged crank. I'd also use some Inconal exhaust valves with a sevier duty stainless on the intake. Might as well go for a cam thats desgined to work with your blower as well. Now your fuel system and ignition will need to be modified for your intended use. Plus you will have to have a free flowing exhaust to compliment your incresed air flow through the engine. Now you would have a nice foundation to build some power and have some longivitity....

What he said, i have a whipple it runs 5-6 psi boost, my engine is 9:1 compression, it will hard on her, have to run premium and octane boost aswell most likley, AND it will genereate tremendous heat. I was planning on putting it on the factory engine and see how it does for a summer and build up a long block special for this application. Also Consider that upgrades to fuel and ignition sytems are required, plus cooling sytem and transmission upgrades, it kinda soaks into the truck the things required to upgrade, may need better driveshafts and differentials, i know i will have to get a detroit locker or a really good limited slip unit, cause even now my factory limited system sucks...

What about prematurely wearing down the engine? All that power would have an effect on the engines life potential? Or if it si built correctly like what you guys said, it will last as long as a stock engine?

Yes a properly built engine using forged internals will last under a blower. What kills a blower motor very fast is predetination. This is why it is very important to get your F/A ratio correct, retard your ingition and use a "good" grade of fuel that will support the amount of boost you are running. Whipple seems to have done their homework in this area. They are very popular in the marine enviroment. Check them out and give Dustin a call....

      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

      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”.
