I haven't been on here very much recently and I'm planning to return on here as a regular. I tried the search and found nothing on this. I'm looking for the fastest Tahoe/Yukon/Denali naturally aspirated time. I see plenty on here with turbo's, superchargers, and nitrous. Who is big dog in N/A for the sport utilities???

I don't think you are going to find much info. All the fast SUVs, I have seen, like you said are FI. I am guessing 14s is about all you are going to see. Some 13s might pop up but I don't think anybody started make covered wagons fast till them compressor things became so popular.

I will take this moment to shine as I will be top dog of the thread atleast for a few minutes. My tahoe went 16.4 I think at 8x mph. Stock as I daily drive! Can someone top that? haha

Not much of a track guy but I ran a 13.9@99 with headers, 50shot and tune about 2yrs ago.. I'm probably touching 12.9s now. Probably doesn't help you much but just wanted to say..

How's yours running?

I ran a 14.0@100 last year with it with a broken gov-lock. I've since changed out the stock exhaust that was still on it and once I get a new diff I will get back out there. Without a doubt it will go 12's with a few changes and I will likely not stop playing with it until way past that. 14.0@100 was stock airbox, stock exhasust, 3.42 gear, stock torque converter, 10 year old Firestone Wilderness 265/70R16, unported 5.3L heads, stock intake, etc. I guess I'll have to go after the boosted guys. I do get better milage than the stock 5.3L that came in it.
