Too Rich?
As my car goes back together I am stepping up the fuel system to prepare for future mods. As my finances stand I can only purchase a few parts as this goes back together.
My question is am I going to be running too rich with a Walbro 255lph pump and 720cc secondaries in collaboration with my intake and exhuast. I can afford these two parts but not anything to tune (S-AFC) them. While the car is apart I'd rather replace the injectors now than later. Please advise. |
More than likely you will be running rich. Rich is better than lean though. Just save up and get the s-afc after you get the car back together. Just my thoughts.

Why does everone seem to think that an S-AFC is a replacement for fuel mods? :rolleyes:
|
Rich is better than lean, however...
Can you afford the gas? On my vert with with rebuilt, streetported engine, stock injectors and stock fuel pump, I was only getting 6-8 miles to the gallon (don't know why it was running so rich). I had to get the S-AFC installed so I could lean it out just to be able to drive it and break in the engine. Dan |

Frank,
You can always leave the car parked till you get the S-AFC to control your injectors. The pumps is a must with the exhaust you have, injectors are a nice plus while I am rebuilding your car. Since $ are limited you could go to a blood bank and/or sperm bank and make some fast cash.:mspank: :crzyeye: I would get the parts and wait for the S-AFC, then I would tune and drive the daylight out of her. |
Mark, answer your cell phone voice mail :P
|
what is a "s-afc" and is one important to a N/A model? are there any other ways to lean out a N/A without purchasing one of these s-afc's? thanks!

Originally posted by NZConvertible Not just rich, very rich! Black smoke rich probably. That's about 15% more fuel than the ECU thinks it's injecting, probably more with the pump. You'll lose a fair bit of power running that rich, making extra boost pointless. Leave the injectors until you can afford the S-AFC (and lay off the boost), but do the pump. :) |
