thanks for the info.. seen the whipple charger looks much better than the old skool Jackson.. dont really know how the tvs system works.. can all these be inter-cooled or gonna have the same issue as Jackson need an separate after cooler?
Rotrex is another option but isnt as robust as the twinscrew.. but easy to intercool
would be good to speak to someone who knows about mapping the jrsc so i can get the best out of it.. while i have it
