Thanks to Aaron for taking time out of his busy schedule to answer our question! Check out previous installments of One Question content right here.Ordering a fuel cell system can be complex. This solution has proven itself over and over again as effective in real competition use. This system ensures that the important pumps feeding the engine are always fully submerged in fuel even If the OEM fuel pump becomes starved. Inside the surge tank resides the fuel pump (or pumps) that are now feeding the engine. The submerged pump in the factory tank no longer feeds the engine, but is instead is used to move fuel to the surge tank, with the excess overflowing back to the OEM tank.
#RADIUM FUEL INSTALL#
A fuel surge tank is a universal device that can install in most any vehicle. For highly competitive racing, this extra weight can be a significant penalty.Ī better solution is to use a device that is specifically designed to prevent fuel starvation from happening. At about 6 pounds per gallon for gasoline, that is a lot of extra weight to carry around in a 12 gallon tank, especially if the vehicle is only using 3 gallons per session, for example. Secondly, carrying a maximum volume of fuel is HEAVY.
#RADIUM FUEL FULL#
This means your full tank of fuel will be down to half tank or less in no time at all, and by the end of your session, you will be experiencing fuel starvation again. First, engines consume fuel at a MUCH higher rate when used in competition. While this makes sense, there are a couple issues with this. The most basic quasi-solution is to always run with a full tank of fuel. To prevent fuel starvation, a racer can do several things. A starved fuel system results in lean air/fuel ratio conditions when the engine is under load, this can cause catastrophic internal engine damage from detonation.
In a naturally aspirated application, fuel starvation results in hesitation coming out of a corner, exactly when you need to accelerate! For a vehicle with forced induction, those effects can be even worse. What are the issues fuel starvation can cause in a racing application, and how can the racer prevent it from happening?Īaron Suchy, Radium Engineering: Fuel starvation can be a big problem in vehicles with poorly baffled OEM fuel tanks and can lead to several issues during racing.
Radium is a manufacturer of fuel system components, from surge tanks-which Aaron talks about below-to fuel rails, fuel pulse dampers, fittings, and even oil system catch cans. He has graciously agreed to take part in Front Street’s One Question segment this month. That’s where Aaron Suchy, co-founder of Radium Engineering, comes into the picture. Because without the necessary volume and pressure supplied by your fuel system, there will be no whooshy noises, killer exhaust note, or record-setting lap times. More so than your turbocharger, or your transmission, or even the driver. Ultimately, the fuel system trumps all when it comes to sustaining performance. And even though those factory fuel systems might be perfectly adequate for a typical road-going car, throw them into a situation when high load forces are acting on the fuel tank and you’re basically guaranteed to see the engine deprived of its necessary fuel supply. Over the last couple of years, as OE engines like the Coyote and LS/LT brothers have become more powerful, I’ve seen lots of them swapped into road racers and drift cars among others. I just know I’ve seen my fair share of blown-up stuff because of a lack of fueling capability. My go-to response is to always have more than you need, but I typically refrain from giving a detailed recommendation as I am not an engineer. People are looking for input regarding what they need, why they need it, and how they can prevent their car from having issues at the track. One topic that’s always hanging around is the fuel system and its capabilities. Throughout my travels, I often get into discussions with enthusiasts at car shows, racing events, Cars & Coffee, and even in random Facebook group posts.
