Fuel Injector Sizing For Supercharger
In need of some technical advice. I'm in the midst of assembling the parts needed to install a Paxton SN2000 on my 89 Corvette. I have recently purchased a Flash II ECM from Dynamic EFI. Id like to NOT run an FMU with my setup and prefer to tune for injector size. Will #36 injectors be adequate for my setup? I will most likely only be seeing 5 PSI out of this blower.

36 lb injectors will easily support 460 HP so unless you plan to make more than 460 HP they will be fine. If your engine is stock besides a blower I would estimate you to be in the 330 HP range.

Yes my engine is stock. Im hoping i can get away with 36 lb injectors using a tune and no FMU.

Just try to stick with injectors that have the offset tables available. It makes tuning, especially at idle a lot easier. Attached is a table with quite a few-just have to convert for microseconds if need be for your tables.
