  • Throttle Body Heat Shield

    Its 2024 and this needs a bit of an update. We have been using 3D printed materials and had to use a throttle body heat shield to keep the header from melting our part. This was PETG, so definitely not the best for this application, but the shield worked. It was made of steel and bolted to the bottom 2 bolts of the throttle body. Also in a race car, which is a different scenario than the original article was written for. We originally wrote that a metal heat shield is going to become a heat sink, and we also mentioned the throttle bodies had coolant ran through them. That isn't the case for drive by wire engines.

    So, its not really a myth for all applications. For a street car, especially one without headers, this is not going to be an improvement.

      I have some experience designing working heat shields. The most important tool in a IR Thermometer. Take temps before and after each modification. Experiment, it is more or an art than science. You will be surprised of what you will find. If you do not take temps you be makeing things worse.

  • Throttle Body Spacer
    by bszopi
    Port injection The TB spacer is meant to keep the throttle body cooler, by separating it from the manifold using a phenolic material instead of metal. The misconception is that by adding space behind the TB, you are going to get more torque. The lowered temperature is fine, and is worthwhile (see TB coolant bypass), but the cost of a spacer and the remaining intake manifold temperature doesn't do a whole lot on its own. The performance myth with this device is that it allows more air in...

  • Throttle Body Coolant Bypass
    by bszopi
    This isn't so much a myth, as it is exaggerated. The lines were put in by GM for cold climate conditions, which is said to cause ice to form on TB, which could cause a lot of problems, like a stuck open condition that can cause an accident. There have been no known reports of this happening, but there hasn't been any research either. ...

  • Thermostat
    by bszopi
    I'm going to keep this short, because its a simple concept. For years people have been spreading the word that a 160 stat will cause problems. This is true, as it hurts gas milage and MAY cause the cylinder walls to wear faster due to less expansion. If your fan turn on times aren't matched, it can allow a cycle of 160 to 220 degrees back and forth, which will contract and expand the cylinders. ...

  • IAT Resistor Mod
    by bszopi
    IAT stands for Intake Air Temperature. It is a simple thermistor that changes its resistance according to the temperature it is at. The idea beind this modification, is that by changing the resistance to that of a cooler interpreted reading, you will get more fuel. While it is true that you will dump more fuel...its false that this is a good idea. Running rich is bad for performance, so you are just wasting your time with adding more fuel in this fashion. ...
