I race in nasa time trials. As such there is a point for mod system which I need to use the best to my ability to be/stay competitive. One area I believe I can gain some points back from is the fuel pump points. There is a modification listed that gives me 2 point if I run an non-OEM fuel pump. For reference 2 points is worth 30 pounds. I have been running a Walbro ever since I started racing because its cheap insurance. I do not and will not have upgraded injectors, or turbos while running this car.
My question ultimately is, does the stock fuel pump have enough capacity to deal with anything a stock CT-26 can put out power wise?
I constantly run the car on the edge of fuel cut, occasionally hitting it during a session depending on ambient temperature. I plan on bypassing fuel cut and based on compressor outlet temperatures determining where this turbo, with my particular setup, really starts to fall off.
My thoughts are I shouldn't have an issue using a new replacement pump, but I want to get some second opinions. I do have a wideband to check if things starts going lean due to lack of capacity but no fuel pressure gauge.
