New EZ EFI Stack 482FE build results

[RICK LAKE]

Bobcowan Bob, Len has the right idea on running a FAST or SpeedPro setup. I ran the other way with using a map sensor on the 452 motor with a .500" lift camshaft. Vacuum was good in the 12-15hg range. The computor just didn't respond well with the map sensor. Changed over to the Alpha "N" way and now the system uses the throttle position sensor for control. Map sensor is just along for the ride. Also need to watch running LOW OHM injectors with a Fast or Speed Pro system. 72 pounds and up are hard on the quad drivers in the unit. They also cause extra heat in the ECU. 50-55 are about the safe limit. If you over build a fuel system you should not have any problems. You want the duty cycles of the injectors to stay under 80%. My 482 motor with 50 pound injectors is only at 62% aT 6,000 RPMS. I have (2) fuel pumps of 255 litre in my gas tank and (2) supply lines of 1/2" to the injector rail with a 3/8" return line. Only down side I see is the fuel gets warm on long runs. 50 pound injectors are good for about 800hp depending on fuel pressure and duty cycle of injectors. They will be in the 90% range. I am going with the TWM 58mm on next motor. I do think that runing a weber base camshaft design may have a better mid range power output than other camshafts. I haven't tryed the lastest rooler from KCR yet, .622" like Phils. Rick L. Ps Bob e-85 gas is OK but IMO and the trouble we are starting to see is you need an alchole carb to not have problems. The E-85 is eating any rubber line that doesn't have a plastice inner linner. We see little black particals in the carbs,float bowls, and jets that get through the filters of 20mm. I don't feel the same power either, just cleaner air out the tail pipe. We have people come in off the road that in winter months have lost between 2-6 mpg of gas mileage. It may ot be oxygen fuel any more but not the good stuff either, just cleaner. To bad the REST of the world is not doing this. ONLY here and charging bigtime for it. Rick
