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

Wow, you really do some quality work. Looks fantastic. I can't wait to see a vid of it running. Also, your patience should be commended.

Looks amazing, can’t wait to see some vids and hear that sweet sweet whine.

Thank you, I appreciate it... I'm generally very patient and always took the "do it once and do it right" approach when working on my cars/trucks. Unfortunately I've had some bad luck on this last build but I've been trying to stay positive and keep reminding myself that it will all be worth it in the end. I lost a full week of testing and tuning because that damn accessory drive.

You know it's really bad when it takes longer to assemble a "bolt on kit" than the time it took me to build the motor and R&R all the drivetrain components. It's frustrating to say the least but it will be worth it in the end (that's what I keep telling myself). It just really sucks because this is my daily driver. I was driving my dogs Jeep Cherokee Sport but unfortunately it's a 2000 and the cylinder head cracked on me halfway through this build. I was lucky to have my brothers car to drive for a few weeks but it was a lease that was due back last week. He's the one with the Audi RS5 and doesn't understand all the work I've put in to this thing. He kept telling me to sell it and asked me what color GMC Terrain I wanted lmao.... I had one of those for my ex wife and it was a Denali and I still hated it. I love this truck and I can't wait to blow the doors off of his $95k Audi. That will be priceless and totally worth all the ******** I've been through with this truck.

I'm sitting here waiting for the mail to arrive and will get this all back together tonight. Hopefully if all goes well I can post a video of the first start up tonight or tomorrow. Either way it will be back on the road this week and I can take off my snow tires lmao...

Thanks, you and me both. It should have a hell of a whine now that I'm spinning the blower even faster. First build it was about 17k RPM and now that I've decided to swap to a 9.1" 10% lower it will be closer to 25k RPM. It's gonna sound wicked!

awesome man...
im a little worried for your LSA blower though

any plans to step it up to a 2300 or try and find a new 2650?

Eventually I will probably upgrade but I planned this build right at the edge of critical limits of the blower. It's got new bearings now and I've seen plenty of guys spinning them even faster than I will be. I'm only shifting at 6,800 rpm, some guys run up to 7,200-7,800 with more aggressive pulley combos. Heat is what kills these things and that's why I added such a big ice box and heat exchanger. I plan on an interchiller when a local friend is done with development...

If I ever really need more than 850hp or smoke the blower (most guys are making over 700whp with similar and less aggressive combos) I will probably go with a Turbo or 2650 blower. Let's hope that's not an issue lol

Oh yeah that’s gonna sound like a banshee screaming in the night! Or maybe that will just be your passengers lol

Cats were torched? They look ok in the pics. What happened?

Was wondering what happened to this thread, good work and I can't wait to see what it does. As far as the blower screaming, mines pretty quiet and I can barely hear it in the cabin. The LSA is a quiet blower.

Trucks looking great, love this build

My combo is a total of 38% overdrive and 3.6 pulley ratio. Blower will be spinning at 24,480 RPM @ 6,800 RPM...

Here's a good chart that shows combos and boost: https://weaponxmotorsports.com/blog...able-pulley-combos-and-supporting-mods-needed

They weren't torched but one of them started to collapse inside. I have a picture of it but u gotta find it...

True, I can't hear crap over the Kooks 1 7/8" headers and exhaust. Still should have a nice sound from outside the truck.
