Let's sift through every square inch of a 2013 Tahoe PPV

I've accepted cutting and patching my stock intake, but...

It still bothers me that the Airaid is the only option for such a simple part.

I'm going to walk around at the yard with a stock intake tube in my hands and try to find something from another vehicle that fits.

Godspeed, young Padawan. Might I suggest you focus on diesel trucks?

A fricking spectre cold air intake showed up at the yard today!

I grabbed the tube and rubber couplings. Yay.

Today is race day!

The weather looks perfect. Nice and cool, with no rain.

I will experiment with a few different methods... Traction control on/off, manual vs auto shifting, etc.

Coming soon is a picture of this intake tube, and some crappy phone videos of me racing a Marauder.

The intake tube was kind of an awkward fit, since I'm not using it for it's intended purpose, but it works.

I'm not sure if I have a way of hosting a video file right now. I don't use social media, other than car forums.

My buddy didn't run his Marauder, but I have a good video of me running a 4th gen Z28.

My times weren't quite what I was expecting, but still respectable for a full-size truck:

Best 1/4 was 15.8 @ 87 mph
Best 1/8 was 10.2 @ 70 mph
Best 60 ft was 2.4
Best reaction time was .000 (no joke)

The shift points are definitely too high right now, but it may just be because I still have stock exhaust. Getting rid of the suitcase muffler might help the top end a bit.

GU4 for the win!

Interesting. I thought for sure you'd be at least borderline 15-14 with a tune, 6-speed and being lighter than mine. Mine (4-speed, AFM-off tune only) with MIT and AEM filter, 18" straight-through muffler and 22s went 15.656 @ 89. 10.2 @ 71 in the eighth. Temp was 55°. I'm assuming Byron? Maybe it's the elevation? I'm ~25' ASL.

Why'd your buddy punk out?

I think the exhaust is holding me back quite a bit. I have the suitcase + the stock resonator, which reduces the pipe diameter there at the tailpipe.

I'm also a bit skeptical of this intake tube. If you look closely at the pic, you can see how the tube extends really far into the elbow, almost like a kink. The analogy would be like mandrel bent exhaust vs non-mandrel bent. Actually, the rubber elbow itself is kinked like this, so it gets narrow at the bend.

Byron, correct.

Again, my shift points are too high for my setup. There is a couple hundred RPM of "not much" at the top of each gear.

One thing I should add is that my times were shockingly consistent. I mean, all the way down the time slip, the numbers were basically the same on every pass.

Oh, as far as my buddy with the Marauder...

I honestly think he was nervous about losing to an SUV, and he wanted to see what I ran. His Marauder is stock, so it's surely somewhere in the mid-high 14s.

He brought his 92 Caprice, which runs high 10s, but he had street tires on it, so he was really just messing around.

The same friend also has a TBSS, a lifted Duramax truck, an old GTO, and a WRX hatch.
