Both engines have the same injectors and dual fuel pumps. However, they max out around 65 psi. The fuel pumps are controlled by a module that increases fuel pressure in relation to boost. There are aftermarket pumps and voltage controllers that will work with the factory ECM to increase capacity.
The CP Carrillo-backed Top Alcohol Funny Car pilot left the starting line with a psychic .029-second reaction time and kept right on going for a 5.425, 269.67 win over Swede Ulf Leanders’ 5.508, 268.33. Aggressively testing in Phoenix prior to the Winternationals paid off for Top Alcohol Dragster driver Shawn Cowie, who scored his 11th national event win and second season-opener Wally with a defeat of Garrett Bateman.
You’ve got questions. We’ve got answers. We work with the Summit Racing tech department to tackle your automotive-related conundrums. This week, we’re talking about swapping a 350 crate engine into an ’85 IROC-Z Camaro currently powered by a 305 TPI engine.
I was told I could have a custom computer chip burned so I could run TPI fuel injection on the 350. The EFI system will be modified with an Edelbrock High-Flow base manifold and runners, ported stock plenum, 52mm throttle body, bigger injectors, and an adjustable fuel pressure regulator. I will be using 1-5/8-inch headers and a 3-inch dual exhaust.
