Message: [QUOTE="JCart, post: 1539286, member: 1238"] Thanks for info to chew on fellas. When comparing a stock 15 degree pumps pressure output say between off idle and say 2600 RPM to an aftermarket pump like a T500 would be interesting to see a pressure table/graph duty/cycle comparison. Thinking to map with A/E would look the same though right? Or perhaps duty cycle for the T500 would be less, due to great volume output? I understand that a T500 has greater pressure max, as noted above, but wouldn’t this also impact Duty cycle causing pressure to ramp up quicker than a stock pump? The pressure increase is caused by more volume output of T500, as pressure is a measure of restriction no? Guess what I’m getting at is there a tangible felt benefit to running (in my instance) a T500 as I have one on the shelf just back from Joey. I could see where possibly throttle feel would be crisper and possibly better fuel economy via better atomization? j [/QUOTE]
