darkbluemn Posted August 18, 2018 Share Posted August 18, 2018 Hi, I will be joining TT later this year. I drive 2013 BRZ and am planing to build a TT5 car. I did go through TT5 rule but still got some questions. Hope I can get correct answers here. - Can I run E85? - I dynoed at 185 max HP on Mustang dyno, and I did the avg power calculation and it's about avg 170 hp. Does it sounds right? Cause it's a big difference. I will do DynoJet in few weeks. - Can I use diffuser? My diffuser starts from rear lower control arm bracket. - Can I use aftermarket LSD and drive shaft? - Does BRZ apply for the -0.7 point for rear a arm? It sounds like a big penalty and nothing I can do about it. That suspension penalty seems apply to most modern cars. Bill Quote Link to comment Share on other sites More sharing options...
