I will be purchasingg a new truck soon and building the bank account for upgrades, which will be done in three stages. There will likely be 4-6 months between each of the upgrade sessions.

2016 Escalade or Yukon Denali
45k miles or less
6.2L L86
8 speed trans 8L90

Goal is 600hp at the wheels on 91 octane

I hope to get there with a combination of the following:

- Whipple 2.9L

- Cam Upgrade Brian Tooley w AFM and VVT delete, +32% fuel lobe

-Cold Air Intake

- Longtube Headers

- Corsa Catback

- Dyno Tune

My two main questions are:

1. After CAI, Headers and Catback, should I do the Whipple first or the Cam?

2. If I do the cam first, can I run a Supercharger spec Cam for a few months before the Whipple goes on?


We have access to e85, but I believe the injectors in the L86 may come up short, even with the +32% fuel lobe on the new cam.

I do not object to running water/methanol injection, if required or suggested.

Trans is rated for 650 hp (485 kW), 635 lb-ft ta (860 Nm) 738 lb-ft (1000 Nm) gearbox

Thanks in Advance

Air first then build your blower motor, at least that's what I did. I'm using a tvs 1900 though, they come on so fast it almost scares me lol. Not sure about the whipple but you could hit 600 easy without a cam with a tvs I went into mine bc it's a 5.3 and I needed to remove dod and amf parts...

 

Don't forget that the gov bomb should be changed out, it won't like 500-600hp of abuse for very long.

 

Yea, I agree 100%. I cracked my carrier completely across it was a 1/2" wide at one point in the break. Lol. I'd do it first, I got lucky and caught it before it grenaded and took out trans, tail shaft housing and transfer case. That break can get pricy fast especially on a 4x4.

 

Richard Holdener always says "every cam is a blower cam, a turbo cam, a nitrous cam and an N/A cam."

 

Was hoping to stay stock on the driveline

The 8L90 Trans is rated for 650 hp (485 kW), 635 lb-ft ta (860 Nm) 738 lb-ft (1000 Nm) gearbox

i plan on sticking with the factory 22” wheels and probably 285/45 tires. This should be a little more gentle than running 33’s like Smokinlmm

Truck will be AWD

 

The transmission should be fine so long as the tune is dialed.

It's just the other two things that need attention. The factory rear locker is not that strong. Add 200+ more horsepower and that G80 is not going to be happy. The next piece is the stock rear driveshaft. They aren't rated to go above whatever the factory speed limiter is set too. High speeds and lots of power is known to make them come apart and break a ton of stuff in the process.

 

Good luck with the trans, I’ve heard nothing but horror stories on the 8spd.

 

the 14 bolt G80s are weak? I think hes gonna be fine. He has the 9.5" AAM SF out back and those G80s are pretty stout

 

Thanks for the input on the drivetrain


Is there any advantage to doing the Cam before the Whipple?

If I do the cam first, I will be able to do the trunnion upgrade, springs, delete VVT and AFM at the same time, which will theoretically improve durability/reliability.

Sounds like there is no issue with running the “Suoercharger Cam” on the NA motor for six moths.

If I install the Whipple first; I will run the Whipple tune until after the Cam upgrade, which will save $500-600.
