Prompted by some recent posts by @Dantheman1540, I wanted to see how it would do with a cold start, in cold weather and after it had been sitting for a while. As of this morning, the Tahoe had not been started in about two weeks. I got out at 7am to take advantage of the 32° weather and make a video.

I shot the video from straight ahead to be able to hear both sides should either one have any noises. The cranking was noticeably slower than normal, but that's probably mostly due to the cold battery. I'll have it parked back in the shop soon, and I'll keep it on the maintainer. There were no odd noises upon startup- no lifter ticks, no exhaust leaks, no dry pulleys, etc.:



Made a warm idle vid, just cuz:




Yo man what's the story on those exhaust tip setups I don't recall seeing those before.

I change them whenever I get the nerve. The ones before, when I made my own resonator delete, were the passenger side dual tips from a Pontiac G8 GT. The current one is the passenger side from an '08 Saturn Outlook. I check out car's exhaust tips as I drive around for work every day and take note of the ones I like. Then I find those cars at my local LKQ and get the tips off. This one flows very well with the curves and angles of the bumper cover, but I don't like one particular angle. If I keep it, I'll have it come out the side more like how my dual round tips did.

Replaced my leaky radiator in hopes that I'll be off work early enough tomorrow to get to the track. Also replaced my gas cap and rear glass lift struts.

Denso 2219514 radiator. Has 1 5/16" core, trans oil cooler and engine oil cooler. Original rad has 1" core and TOC only. I have a GM engine oil cooler line set (GM #20828695) on deck for when I change the oil. I got the Denso rad and the EOC line set for the same cost as just the stock-replacement GM rad.

Denso rad has a drain. I used a 19mm socket to turn it by hand to ensure it was closed. It must've been damaged in shipping cuz it snapped way too easily. Yes, I'm overdue to clip my nails. Been busy:

I used an EZ-out to get the remains out. I didn't have a large enough metric bolt so I just applied thread sealer to the plug and screwed it in tightly with a flat head screwdriver wedged in the hole. I'll probably never drain the rad so I'm not concerned about it:

While I had the access, I cleaned the A/C condenser by spraying it from the inside out with the garden hose. I had to spray the coolant off the frame and splash guard anyway.

Rushed and stressed myself today to get home early enough to fill the radiator and get to the track. I stopped at Walmart on the way home for some coolant concentrate and a few gallons of distilled water. While I was there, I checked the track's calendar and saw that they weren't even doing TNT tonight and that it'll be on Sunday, starting at 10:00. So I chilled out and grabbed a few more items. Oh well, it gives that thread sealant an extra day to cure.

Got to the track around 10:30 this morning. Ambient was 55°, just like when I made my baseline runs last March. My best at that time was 15.656 @ 89.05. First pass as-is, stomping it with traction control on, it went 14.698 @ 94.61. So I started out really happy. I got three more runs in with about 20 minutes of cool-down between each (hood up). Second run was with all TC nannies off and slightly pedaling it, and it was just slower all around. Third run, I lined up with a Suburban that I assumed was a 2010+ and had the 6L80. I believe he was cammed. He ran again then left as I was cooling down so I never got to chat him up. For that race, I decided to actually try to cut the lights so my RT was much better than runs 1 and 2. Stomping it with the nannies off, it surprised me with a little tire scratch. I won that one, but he was gaining. That big bastard had some top end, or maybe it was his choice of wheel and tire that hurt his launch. Reading the time slip tells the story as he was over 1.5 MPH faster at the 1/8 and almost 3 MPH at the 1/4. I really wish I could've checked him out. For the last run, I had cooled for about 30 mins and ambient was around 57°. Stomped it at the last amber and it scratched the tires noticeably harder than the previous run. That one was the best of the day with a 14.672 @ 94.69. Oh, I didn't stall it on any runs. Playing with it on the street, I've tried to stall it but Torque Management kills it badly. So I didn't stall it at the track.

So, I gained a second with the mods, which is what I was hoping for. I'm satisfied.

Nice times a full second is a big difference!
