Not Ranked
BillE I have F.A.S.T ECU on my car for the wide O2 sensor reading The holley system is OK but is limited to 500 hp I have the 1200 cfm throttle body on my car and are very happy with the preformance with it. The fast system is flexiable I can run 30 lbs low ohm injectors or 96 lbs injector by switching the injectors and siding the other program in. You can upgrade this system any time through the company and have overnight return or swap the next day. I had a poor ground wire and burnt a shunt in the ECU, sent it in, fixed and return in 2 days at no charge except the shipping. You can but a 2000 cfm throttle body on your motor if 1200 in not big enough. I can lug my motor down to 1200 rpm in 5 gear and step on the gas and it pick right up without black smoke, flooded motors, wet spark plugs. The only places a carb is better than FI is in being orginal, cheaper, and over 7500 rpms, it makes more power top end. Overall driviablity still goes to the FI. A couple of magizines have none this testing. Fuel mileage is better too and emmissions. It's up to you. You need to add larger fuel lines (2) min 3/8 and 1/4 return. 255 lbs pump in the tank. I have(2) 1/2 inch supply lines and (1) 3/8 return line. 2 electric 255 fuel pumps in the tank. If racing keep 1/2 fuel in the tank has to have no fuel starving problems. I run only 1 pump unless the supercharger is running under boost. This prevents leanouts. If you want to talk about FI more call me 732-254-3536 in the evening up till 12:00 or buy the basic fuel injection books and read up. Don't stop asking questions. Rick Lake
