hey i need a 12.1 rising rate fuel reg what one do you guys recommend?? how much?? can you get one to suit an e series?? could i use and f6 typhoon factory reg??

cheers adrian

Most injectors go static over 80 Lb..
So 8 or 10 to 1 is all I would use..
Keep in mind 40 Lb is fuel pressure at idle
then add 8 Lb 12 X's 8 = 96 plus the 40
Your over 130 PSI..
Which is way to hard on fuel pumps to deliver the quantity to supply
enough fuel at that pressure.. Even two Bosch 044 motorsport pumps will have trouble!!
Again invest in a cheap stand alone ecu.. There are some around $1000.. EMs Stinger, Microtech, E6K Haltech etc.. check E bay ??
