Owner’s Blog 11/18/12
Sunday at home is a very strange day for me. Since March, I have been spending weekends on the road at Mustang races and events with our sales trailer and crew. Since I am a single workaholic, I can’t sit at home and relax. I don’t know how. So I am going to UPR to work on our 2011 Hellion single turbo Mustang.
Last time at the track when we turned up the boost I noticed a couple of hardly audible misfires top end. I then realized that we had the original spark plugs in the engine with the factory gap. So I’m going to install a fresh set of plugs and reduce the gap to .025″. The tight gap really makes a difference in guaranteeing successful combustion under boost. And countless tests on our dyno and Billy Glidden’s have shown me that there is no horsepower advantage to a wider gap. I can also install a set of our new UPR billet idler and tensioner double-bearing pulleys for the 5.0 Coyote, and take some pictures for our website. After that, I plan to start replacing the braided fuel lines on our 2003 twin turbo Cobra which has been sitting for years.
I want to talk about what I’ve learned about intuition and your car. You can read all you want about your car and listen to all the internet “experts” but when it comes to your own vehicle, nobody knows it better than you. At UPR, I have a strict rule about what salespeople say to customers- NEVER use terms like “no way” or “impossible” or “I’ve never heard of that so it can’t be true”. When a customer calls in and describes a situation that we at UPR have never heard of, our only goal should be to try and work with the customer to help him and come up with a solution to help others in the future. It is an opportunity to learn something. To imply a customer is lying or hallucinating is a slap in the face to our fellow enthusiasts and, frankly, the people that we appreciate most- our customers.
Anyway, I have learned that if you sense something might not be right with your car like a vibration or strange sound, don’t ignore it. That nagging feeling of doubt in the back of your mind can save you money and maybe prevent injury if you listen to it. For example, detonation (pinging), if not dealt with immediately can lead to blown head gaskets and even damaged heads, pistons, or blocks. Or a vibration can be a failing u-joint (which leads to driveshaft failure) or loose lugnuts or failed wheel bearing or internal tire damage. “Ignore it, it’s probably nothing important” has no place in the enthusiasts’ vocabulary.
