Q16 Race Gas + 514 Inch Mopar = 900 Hp

BLP Shows Us How to Modify Our 1250 Dominator to Run Q16

- Andy Finkbeiner

Q16 race gas has earned its reputation as the fuel to use when looking for extra power. When we tried running Q16 a while back, our carb wasn’t set up properly and we hurt some parts, so this time we went looking for professional help. When it comes to carburetors, it doesn’t get any better than the folks at BLP Racing. BLP is a key player in the carb business, with the ability to build complete carburetors, as well as most any related component. We described our past experience to the BLP tech team, and they quickly set us straight on what we needed to do to run a highly oxygenated fuel like Q16.

The stoichiometric ratio for Q16 is 13.6:1, as compared to the more typical 14.7:1 figure used for pump gas. If you divide 14.7 by 13.6, you get 1.08, which means you need 8-percent more Q16 flowing through the carb to maintain the correct air/fuel ratio. On the surface, it seems that just jetting your carb up by 8 percent will work, but in reality, there are limits inside the carburetor that may likely prevent that from working in all situations.
