All you're doing is altering the intake, which shouldn't make a difference?Either way, good to see you're building it bigger and better.What kind of clutch do you have?just the standard typhoon twin plate clutch for the moment.. I have not had a problem slipping yet but im sure it soon will lol..Geoff went from a 3" intake to a 4" on a pretty hi powered tune christian, there is a big difference between that and simpley putting a growler on a stock car - turbo spool is much faster, hence the tendency to overboost alot more.In saying that though, the motor hasn't been torn down yet, so we'll have to wait and see what kind of destruction is in the belly of the beast!yep like senna_t said I upgraded to the 4" intake that combined with no guts in the cat as it come loose and I pulled it out was over boosting big time.. all the way up to around 24psi one time.. saying that when the motor let go I was not going hard or anything only reved to around 4000 then changed to third when it happened..both this things would of helped in what happened.. so if you change to a CAI or up grade your cat get it checked out by your tuner.. couple hundred bucks can save around the 8-9000 I am up for lol.. pain in the ass as I was only a week away to getting it retuned Link to comment Share on other sites More sharing options...

My tale of woe.Also a rebuild kit coming from Brad. Link to comment Share on other sites More sharing options...

I think having the bottom of the plenum off and radiator out helped too a lot more room to play with.. Link to comment Share on other sites More sharing options...
