Suppose it depends on what set up you go for! externally gated manifold and how the manifold has been designed.etc
But with my ct9 set up i've made everything as sort as possible! for extremely quick spool up! And im realy enjoying it at the moment! I would love to buy a nice sexy looking manifold but most of the nice looking ones have long runners and i would like to keep everything short hence why i love the JAM manifold as it keeps everything short but finding one of them for sale is prity much never going to happen lol.
Theres just one more thing id like to change and thats the flywheel that should help rev the engine abit quicker and should bring boost in quicker i would of thought aswell?
