2007 Yukon Denali Build (This got outta hand really quick...)

[Tonyrodz]

I don't think I posted pics of new upper grill with lower installed. Also removed chrome mirror covers and installed body color ones. Chrome trim on hood also blacked out and chrome bug deflector removed and blacked out. Might reinstall deflector because they chipped the paint on the hood with the mounting clips.

Kind of reminds me of Vette wheels.

Have you had any issues with longevity of the motor/drivetrain or concerns of it in the long run? Curious as I have an 07 as well that at the moment runs really good just hitting 95K but still wanting a little more power but need it to last a while.

Not at all, runs great and I beat the crap out of it daily lol... I'm still having some Service Stabilitrak and Service Suspension messages on my DIC after the suspension removal but I'm going to reprogram my BCM to eliminate all that electronic crap anyways since my goal is around 800hp for summer with a 416 short block (don't need traction control lol). I'm still running on the factory bottom end and just hit 156k miles. When I purchased the truck I didn't have the best oil pressure (probably sloppy main bearing clearance from the factory or 10yrs of wear) so I switched to Valvoline 10w40 and don't have any issues here in Michigan in the cold or heat, great oil pressure now.

I also plan to upgrade my cooling system for the supercharger because I'm seeing higher intake temps than I'd like and I had to pull out a ton of power to keep KR (knock retard) below 5 degrees. I will install an interchiller system that ties in to the A/C and it will give me 20 - 30 degree IAT temps, should pick up another 75hp between that and adding the timing back in. The truck is a complete beast in it's current form, can't wait to really start pushing it.

Other things to check is the front differential and transmission at that mileage. My front diff had some metal in it so I change often with Mobil 1 synthetic and will rebuild it when I do the short block. I've also rebuilt my transmission so not much else to worry about really, just flush the transfer case. Getting it tuned properly is the difference between life and death for the transmission (even stock) and the engine. I spent a TON of time with HP Tuners creating an injector map for the CTSV injectors due to VVT. I took my stock cal and a stock CTSV cal and kinda merged them together with some tweaks.

Lemme know if you have any other questions, happy to help...

Yesterday was sunny and 55 in Michigan. Cleaned her up and now we have snow... Guess it's time to get dirty and go do some donuts lol. Video later if your lucky

 

[67RS427]

8" of snow here and I took it to the one parking lot that was plowed and did donuts lol... Enjoy!

Love it! Sounds great. I hear a little whine.

Hard to hear the whine over the Kooks headers lol. Gonna do a pulley change soon and spin the blower a lot more, should really hear it then

 

[992dr]

Man, that sounds awesome.
Looks like some fun too

 

[Fosscore]

Kooks and SC sound great. Nice donuts.

 

[67RS427]

So I was playing around with HP Tuners today and realized the ECU was still pulling Spark and Fuel for traction control... Shut all that crap off and added 5 degrees of timing from 2,600-6,200 RPM. Should make A LOT more power now. Will update with another donut video perhaps lol

 

[67RS427]

Get ready for more boost hahaha...

Received my 2.5" pulley today from WeaponX Motorsports. I've got some plans for the next 2 weeks that I'm very excited about. Building up an LQ9 iron block and pulling the Aluminum block. My Wiseco -20cc pistons will arrive tomorrow which will give me around 9.6:1 compression on the new 402" motor thanks to a Lunati Voodoo 4" stroker crank and Lunati H beam rods.

Total boost will be around 12psi with a stock LSA damper for now. New 8 Rib truck accessory kit from LSsimple.net will be installed to help with belt slip. Max boost will be 15.5 lbs should I upgrade my damper with an interchangeable overdrive ring. Can't wait!!!

 

[67RS427]

I'm also contemplating what to do about my transfer case... I don't know if I want to rebuild the BW4485 or not. I might swap in a NV149 and get rid of that POS. Will be rebuilding front and rear differentials at the and time as well and getting some new custom driveshafts so I can safely ? go over 100mph lol

It's about to sound a whole lot better with a stroker crank and a positive displacement cam. Throwing in a 2800 stall while it's apart as well...

A little update from the garage... I got my 6.0 LQ9 block back from being machined. Rotating assembly is now balanced and I already dry fitted the pistons & rods to check clearance for the Lunati 4" stroker crank. The -20cc Wiseco Pistons, Lunati 4" crank and Lunati H beam rods are ready to be installed after a little more block deburring. Also have a Brian Tooley Racing Stage 3 PDS Camshaft, BTR Dual Valve spring kit with Ti retainers and a BTR Trunnion Upgrade Kit. Heres a few pics of the goodies and I will try to keep this build thread updated as I go. I have a 2,800 - 3,000 rpm stall Circle D triple disc torque convertor going in as well. The 402" motor @ 14psi should get me to 750 - 800hp. Also pics of my new LSSimple 8 Rib front drive setup... Very impressed with the quality, I wouldn't use anything else. Stay tuned!!!

Short block coming along nicely...

 

[67RS427]

Things are moving along... Out with the old, in goes the new 402" beast. Wasn't planning on pulling the transmission but my crankshaft was so out of balance from the worn bearings that it chewed up my reman convertor and bell housing of the transmission. Luckily I have this awesome Circle D Triple Disc convertor.
