2013 CTS-V Coupe 6MT Silver/Black
So I live in New England. The Boston area to be a little more precise. I'm on the fence about whether or not to invest in an expansion tank, and if so which one. I don't track my car. It's my daily. But I like to get on it occasionally, and tracking it eventually is not out of the question. For cooling I already have the Track Attack and am about to install the Varimax pump. Aside for it just being a good idea for our cars anyways, my cooling mods were motivated by how quickly our cars heat soak ESPECIALLY in stop and go traffic. So because of that, my cooling mods are just as priority as my go fast parts. And much like with any other rabbits hole I research my way down, there's way too much conflicting opinionated information online. Some say more fluid volume is a must, others say adding more volume only helps temporarily then you have way more fluid that takes way longer to cool down and recover. Again, my needs are more daily driving based. I don't need to ice anything. I just wanna keep it cooler and not heat soak AS BAD in stop n go traffic. So help me out guys. Do I need to do an expansion tank? Or am I good with just the T/A and Varimax. And side note, I was totally sold on the awesome Piersburg pump. Then I got a fantastic deal on the proven Varimax, so I couldn't turn the savings down for a slightly better pump at double the cost.
