MFI and CIS are two different things in Porscheworld, and it appears you know little about either. Well setup MFI has HP advantages over carbs, CIS, and EFI. Right off the bat, there's more HP, you can use seriously rowdy cams, and the throttle response can be phenomenal. CIS makes the car pull like a tractor from minimal RPM to redline, but requires a relatively mild cam. EFI is cleaner, but also requires a mild cam and loses HP and torque. Carbs are dirty, inefficient, and offer poor fuel economy. Good throttle response, but they require serious tinkering to get as right as they can get, which isn't very. The Cap'n

(IMG:style_emoticons/default/agree.gif) That's why I bought my 911. The PO did a stellar job of modding a 2.4 MFI unit (from a T), combined it with S cams and heads (IIRC), and it makes 190 horsepower and the 40-80 acceleration (seat of the pants feel) is phenomenal for a 40 year old car. |

My favorite part about my MFI car was winding it up to redline and letting off the throttle. It would make this incredible intake howl all the way back down to idle, scaring any pedestrians or other drivers in the immediate vicinity... Great fun! |
