I do know there are no great ways to combat turbo lag. First you must consider that Porsche knows what their doing when it comes to turbos; every change you make is compromise. I've seen this go to the extremes of burning holes in pistons and breaking crankshafts. A larger intercooler will allow you to run more boost but it won't reduce lag. The only ways I know of to reduce lag is with a duel turbo setup, or a smaller turbo. There may also be a couple things you can do with the chips and the exhaust. I recommend reading a book, I think its called "Maximum Boost". Sorry, I don't have more details, but I haven't read the book myself yet. You might also try contacting FAT Performance. I have a friend I'll talk to tonight that builds HP 930 motors. james Wayne at Pelican Parts wrote: > Hi there Victor.
