Dyno Review - GMC Denali 6.2l Cam | Headers | LS 

Shouldn't it be making 420 ft lbs torque stock? L92 v8 right? Have the same motor myself.

Delete afm /dod

Lifters maybe exhaust manifold gaskets. Id stay away from the awd models. Worse gas milage and if you damage a tire you need to replace all 4. That goes for all awd vehicles

I'd choose the 6.2 between years 2007-9 as they don't have 'Displacement on Demand'. The awd is great, but does eat up gas mileage, buy will be more reliable in the long run. Pretty much anything 6.2 or 5.3 has 'variable valve timing' that makes for a less reliable engine the 2006 and earlier though. Just do more research.

If you're planning to leave it stock an "off the shelf" program would work well.

@@ForceEngineering sweet. Thank you

I'm really not sure. I don't remember the last one close to stock I've tuned with the AWD driveline.

Looking to do the same with my 07 Denali but I'm going with a more aggressive sound. I was gonna keep it tame but I just saw a video of a blue one just like this but it sounded NASTY lol that's what brought me here lol

Stock my 07 Escalade Esv put down just shy of 360 Hp on the dyno. I can't remember the torque sorry, I'll see if I can find the video. With my GPI VVT1 low lift cam, valve springs, k&n intake, 1 7/8 headers, catless downpipe, corsa exhaust, on a 93 tune I had to stop because I ran out of fuel capacity. When we let out she was climbing past 450hp and you could tell she wasnt even working hard yet. I installed a Flex fuel pump and tank from a 2010 or something and 540cc injectors before I continued doing tuning. She is spot on and has plenty of power from down low all the way to 6500rpm. I'd have to guess I'm around 525-575ish maybe more. Granted the awd sucks the hp rating down quick, don't let her fool you. She tows my 30 foot camper with no issue and can put you back in the seat off the line. Granted if I would have gone a different cam you can pick up over 100+hp just like that, I needed the down low grunt for towing. I do have a brand new VVT1 cam sitting on the shelf if either of you are interested. I should even have the HPTuner file to get you started.

@@TheElderOne2003 what kind of gas mileage are getting? I have a 2011 Denali XL that I’m pulling the motor out next weekend and tearing it down and I want to get rid of AFM and do a cam but curious about gas mileage with a bigger cam than stock. Also what cam part number did you use for yours?

@@geoffbeaubien5124 it all depends if I can keep my foot out of it. City I'm around 12-15mpg, highway I've seen 14-18mpg, and towing my camper fully loaded with the family I average 8-11mpg. But I also run some heavy ass tires. The cam is a GPI VVT1 for the L92

being awd, the loss is greater, i'd put it in the 460 or so flywheel hp area.

@@ForceEngineeringaw nice. So looks like the cam wasn't too bad after all.

@@djwakademikz I feel it did well. Dyno is a tool and without a baseline run we're making educated guesses. But yeah, i was happy with it.

For an AWD cammed 6.2? I thought I was a bit low too tho

Every dyno is different, would need the baseline on that truck when it was stuck amd compare the difference. Being awd, on an awd dyno there's greater drivetrain loss. That could be about 460 at the crank. Too many variables like what TYPE of cam.

no sure what cam it is. Keep in mind its spinning all 4 wheels and the additional driveline here.

@@ForceEngineering ah, forgot it’s got that extra driveline loss.

@@jhalscott I am putting a l9h in my trans am what’s the best cam

@@mikeverything4098 Richard Holdener has a great channel that does a ton of dyno tests with variants of LS motors. Take a look at his tests for cams in the 6.2 L9H. He prefers versions of the Comp cams, but always puts part numbers.

Your talking about power at the flywheel, not at the tire. It takes power to move all the components so there is a power loss to the ground. 25% is the normal calculation for an automatic.

@@ForceEngineering do you think with boost you can get 500 at the wheels

@@Bball128 of course. Easy to make power with forced induction.

Plainwell, Michigan

I’m looking for a shop to tune my Yukon after engine mods (cam, springs, & headers) are done.

@@tajmuhammad580 We can do that if you get it to us. When you're ready shoot us an email. Force-eng@hotmail.com

Dang I’m gonna have to do this to mine I live close to plainwell

@@ForceEngineering need to get my truck tuned where are you guys located and how long does process take.

100% agreed. Unfortunately this happens all the time. People making cam swaps for the sound and then complaining about the lack of low end power.. smh
