I give up. Believe what you want. CIS was a logical step between MFI and EFI. I've owned Porsches that had essentially every type of fuel metering they ever used. They all have good points and bad points. My sunglasses aren't rose-tinted and my memory is still good enough to remember all the downsides to carbs, MFI, etc. so I won't lose any sleep over any of this. I also like PCA, Cayennes and Panameras don't bother me, etc. I'm not you. JR |
Geez, Panameras and Cayennes, too? Your case is hopeless.
Anyway, when I hear "factory race car" I take it to mean raced by the factory (or a factory supported team like the Penske 917.30). So, for example, the Kremer cars- 911ST and 935s are not factory cars to me. The Martini cars are, though, in my definition. Salzburg 917s are the factory team, Gulf gets 1/2 credit. I still believe CIS was a step backwards. The only thing that would get me to switch from MFI is DFI or a DFI injector in the MFI position. |
I bet you like your 911s with SBC V8s in them too.

Corvettes used CIS as far back as '57 and continued to use it until the 350 CU engine came out.
CIS is much easier to turbo charge or supercharge. I've dicked around with the Corvette system. Porsche MFI and CIS and Motronic EFI. No doubt they are dirtier in the reverse order. |
great thread, I learned something. Don't like CIS probably cause i'm coming off a cracked air box and got a air leak....
