I have a 2014 GMC crew cab Denali truck with a 6.2 L direct inject motor. I had Manny and the boys at Dasilva motorsports in Kitchener Ontario install the Magnuson TVS 1900 supercharger and a set of American racing headers. The truck Put down 320RWHP in stock form. The SC gave it 100 RWHP and the headers added about 30 hp more. Truck ran 14.7s in the 1/4 stock and then ran mid 13 with the SC. With the headers the truck got down to very low 13s. With just a bit more fine tuning by ARUN at dasilva's and a good launch in 4wd off the line then switching to 2wd, I got the truck to run several 12.9s. at 104 to 105 mph.

 

My Best was

60 ft .... 1.84\

1/8.....8.28 @ 83mph

1/4 ....12.94 @ 105mph

I am hoping with my build I will get into the 12's. 14' 6.2L, Whipple kit, stainless steel works long tubes and exhaust (no tail pipes) custom dyno tune. 4WD dropped 2/4, stock 275/55/20. System should be in and installed end of month, can't wait!

Any updates? dyno #s? ETs?

Not too shabby. You're running a full size pickup in the same range as my 6.2L Camaro SS!

 

Nice!

Sorry haven't posted or read in some time. With the whipple and headers it dyno'd 530 rwhp. I have not ran it down the track but plan on it this summer. Hooking up is the main issue and might see if there is a good track tire for it to hook up.

The next item will be a cam and maf stand alone tune but that's a little more than 5 grand mostly due to the direct injected motor requires a different cam. This will be good for 50-70 horses.

I drive it daily and have out about 8k trouble free miles on the set up.

Hey 2 slow,stainless steel works headers you have,do you have a part number? I cant find them for 014+ silverado/sierra

They stated it was at 7 pounds at 4500 feet, they only modified the whipple tune that it came with. Premier Complete Auto did the work. They ended up using AR header with high flow cats.

I will be doing a custom tune and MAF sensor and boost gage with possibly a different smaller pulley.

Beefing up the rear suspension will help with your traction issue as well. The right set of shocks tuned properly will make a difference.

 

May also want to upgrade your transmission and drivetrain putting out those kind of numbers. Your factory parts may not last very long, especially running WOT from a launch at a track.

Everything still running good? I'm wanting to do a similar setup but worried about hurting overall longevity. I don't want it to only last till 100k. How's the trans holding up to the extra power?

Why did you truck put down such low numbers stock? Mine stock put down 350/380 at the wheels.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
