2020 Season Recap (Evo)

Major changes came during the 2020 season in the form of an E85 tune, and wow – hard to believe I held off on doing it. With the introduction of the tow car, life on E85 has been very easy, with 20 gallons on board the Sequoia, along with all tools needed to service the…

SpoolinUp Coil-on-Pack

Another long-time modification that I’ve never posted on is my SpoolinUp coil-on-pack. I’ve had this for as long as I can remember, I think on my black Evo, and I was a relatively early adopter of the part. It is a massive improvement over the stock system with excellent build quality, including Denso coil packs…

Kiggly HLA

I’ve been using the Kiggly HLA for 7 or so years in my white Evo, and while I touched on it in this post, I think it deserves its own thread. The HLA was pretty much one of the earliest mods I had done on my white Evo, during the great migration where I moved…

Tomei Crank Scraper

While on the subject of oil, I think the crank scraper also deserves its own post. Pulled more directly from this post, the Tomei crank scraper essentially “slices” oil that is flung from the crank, and allows it to deposit more quickly back into the base of the pan. The baffles/windage trays prevent an excessive…

ATS Front & Rear Differentials

The big mods for the 2021 season are the differentials – specifically, the front and rear differential. This had been planned for the 2020 season, but the crash I had at the end of 2019 ruled that out. The more significant upgrade is the front differential. The stock helical differential is okay, but not ideal…

Antigravity Battery (51R)

After draining the ETX18L, I decided to get a more dedicated battery solution. Antigravity’s new automotive batteries have huge cold cranking amps while also being significantly lighter than most batteries. I opted for the 24ah battery at 8.5lbs, but wound up with the 30ah battery at 11.7lbs instead. The Deka ETX18L it replaces weighs about…

Air Filter (Evo)

Just a small update – new air filter ordered for the Evo (Amsoil EAAU4560-EA). The old one was looking quite worse for the wear and checking my logs, has been trucking on for 3 1/2 years – well past its prime. The availability of the EAAU4560 seems spotty, so I ordered 2, which should last…

UOA 09142020 (Evo)

Another solid UOA result for the Evo. This car was driven HARD over this period of time, with a lot of track days. The Evo is going to start seeing much, much less mileage on the clock as I now have a tow car, so the UOA analyses will likely stop as well. Overall really…
