fuel pressure
Hi, i´m a pride fd owner from germany (europe). ;)
The RX7 tuning community here is very very smal. So i need some informations from you, Here are my importantly mods: -Greddy T78 Singleturbo -Extreme Fuel System: Competition Fuel Rail 1600cc Bosch injectors x2 Nippondenso Fuel Pump Fuel Pressure Regulator FPR Gauge -Stock primaries 550 ccm -Power FC and so on.... My question is, with how much fuel pressure should i drive? :confused: Whit stock pressure, about 30 psi? |
I think he is trying to ascertain if his fuel pump is going to flow enough fuel for his 1600cc secondary set up with a T78 single turbo supplying boost. I am not familiar with the capacity of his Nippondenso fuel pump, so I cannot say. Any help? May need to be on the single turbo forum.

43.5 is the magic number I believe.
Check out Maxcooper's site, for lots of good info on fuel. http://www.maxcooper.com/rx7/how-to/...tem/index.html |
More background would help on this one.
If the car is already tuned, you want to use the base fuel pressure it was tuned so you'd leave it alone. 30 psi at idle would be approx. 36-38 psi base pressure. To check your base pressure, start the car and disconnect the vacuum line to the fuel pressure regulator then check the fuel pressure gauge. If you want to reset the base pressure then tune with a wide band oxygen sensor, do some research in the single turbo section. There are pro's and con's to lower/higher fuel pressures. Jack |
Thanks to all, for your fast replys! :bigthumb:
So i think i stay at the base pressure. But i keep on searching for more informations. Thanks and greets |
