Wondering if anyone has experience/info on installing a Fore L2 or L4 system on a gen 2 whipple car. Is one easier or cleaner to install than the other, if so why?
I’ve done both setups on 3 different Whipple’d S550’s (mine is L4) and doing another L4 soon. I wouldn’t say one is easier than the other but you’re just adding one supply and one return to the regulator with the L2 and you don’t need a Y block either. The L4 requires the Y block and double feed and return to the regulator so technically your setting up less fuel line with the L2. There is some difference cosmetically but one isn’t better over the other. It’s really a personal preference. If your planning on taking the system to it’s full limits or super high injection quantity I might recommend the L4 just based on each fuel rail getting its own supply (parallel).
