Mods for weight and aero... Okay, more for looks. Can't decide.

[iamdub]

you will need the hood as well the hood is different then the normal tahoe... the tail gate is aluminium as well the D plies and steps and flaps the...... the brake lights are LED you may need to do some modding or adding resistors for it to work correctly (or commercial mode) it's not connected to the lower lamp like the normal, the turn Signal is separate circuit for the lower light only from the brake light and running lights

t

Yeah, that's everything on my list. It's probably gonna be an all-or-nothing thing.

I only wish GMT800s had aluminum hoods and low-drag front fascias.
Looks only get you so far, though. For more drag reduction, smooth out the belly:

View attachment 396831
View attachment 396832
Can't see a downside to smoothing out the underbody airflow.

Cool! I've considered belly pans! I'll never do it cuz I do more local drives than highway cruising/top speed jaunts. And I plan on going a little lower. What is that made of and did you notice any improvements?

If it has a battery still, it may simply need reconditioning. Call greenbean battery and see if it has a core value and if there’s a way to have one of their reps do a drive by to discreetly check it out.

On the other hand if the owner finds out he can get unexpected dough from selling off the battery, he may just give you the shell. That’s what another buyer might be doing right now.

If it’s a running non AFM 6.0 it’s swap worthy for any Gen 4 V8.

The seller said he already had a guy that wanted to buy it for the engine. I'd be fine with that if all I got outta the deal was the body parts. It'll come down to price and timing.

I believe they all have afm and vvt cam timing too.

Yup. I'd cam it to lose AFM but try to keep VVT.

alum engine alone would probably save more weight than the hood.

Likely. And I have an LC9 on the stand just in case I ever catch a wild hair or break the LMG.

on a side note, the hybrid yokon's had normal steel hoods and rear hatch. rear glass opens and all.

Interesting. Not as gangsta as the Tahoe. Kinda hard to be gangsta with that cute, bubble-eyed Yukon face, anyway.

the battery is probably shot, but there is electronics in the pack that might be worth a core somewhere. I'm on the side of anything over about 90k miles these batteries are tossed from bad cooling design and being over worked on a truck. it's just a prius battery with a few more cells to raise the voltage.

I really don't wanna drag home this carcass to part out. No time to deal with all that. I really don't need the engine, either. I guess if the battery pack and electronics, etc. are present and worth a few bucks, even as scrap, it might be worth it. I know there were a couple members looking for the aluminum body parts.

So, y'all wouldn't disown me if I gave my Tahoe the Hybrid aero treatment?

 

[j91z28d1]

haha I do like the Tahoe front end better and wasn't looking for a yukon, but it popped up at a deal and since it's the wife's daily and she loves the heated and cooled seats I factored in the price of aftermarket mishimoto headlights before I even picked it up. lol. it's grown on me since then.

bit to much chrome on it for my taste but eh..

I'm horrible with engine codes. what do you have ready to build? the hybrid 6.0 would be nice, since it's Cathedral port and higher compression pistons than the normal ones but still run 87. I guess the 6.2 requires 93. which is over a 1$ more pre gal around here. kinda scammy.

The spare should have an aluminum rim, not steel like all the regular gassers.

 

[Marky Dissod]

What is that made of and did you notice any improvements?

Corrugated plastic aka coroplast.
I myself did not notice any improvements ... yet ...
The major appeal is that only my mech will know that I'm an aero-focused EcoModder.

So, y'all wouldn't disown me if I gave my Tahoe the Hybrid aero treatment?

If it more resembles a Tahoe Hybrid, than a Toy-Odor Pious, then we'd have no good reason to disown you!

It'd be INCREDIBLY difficult aero-modding a GMT900 to exceed 27MpG highway without making a Toy-Odor Pious look sane by comparison, which won't guarantee that the EcoModder forum will accept you.

I have a 140K-mile LC9 from an '08 (or '09?) 4WD Sierra on the stand. That's an aluminum block 5.3 with AFM. It's basically identical to my LMG but with an aluminum block instead of iron. I bought it to have on standby when my LMG lost a cylinder last year and I hadn't had a chance to diagnose. Turns out it was "just" a broken valve spring and bent valve that I was able to quickly repair without pulling the engine.

The 6.0 would be cool to have and build. But I'm not looking to do anything like that at the moment. I'm already near 400 with my cammed LMG so I'd have to work over the 6.0 to make it worth it. It's just not anything I'm in the market for right now so I wouldn't be sour if that other guy got the engine.

The 6.2 really does need 93 and I don't care what everyone else with Escalades and Denalis say about their 6.2s on 87. I'd strictly use 93 if I had a 6.2. My LMG is tuned on the ragged edge for 91-93 and I'm fine with running it. It's just a weekend vehicle so fuel costs aren't such a factor.

Yup. And, due to the drop spindles, it's yet another item I wouldn't be able to use unless it's 18". It's probably the same as the one my Tahoe Twin has. His is an XFE.
