Fueling & Injection - 255 in tank + 255 in line
04-28-2012, 11:36 PM
I have a 97 camaro with a 383 and a supercharger right now i have 60# injectors and the stock in tank pump with a 255 inline. My question is how much horsepower will running a 255 in tank with my 255 in line support?

If you run in series, you will get no more flow than just the inline pump (closest to the engine) can deliver-which a 255 high pressure pump (GSL392) will support about 450rwhp depending on your fuel pressure. If you run them in parallel/dual, you can support about 750rwhp

Typically adding an inline pump does very little to boost the flow.
These are usually used to boost pressure (such as with a FMU on boosted cars), but will not do much if you are running normal pressures.
If you are interested in a pump system for your car, give me a call.
I can get you the best setup for your needs.
