Around $6500 for 30 to 50whp.....ummmmmm BIG things ??????
It said 7 psi on the street SC and 11psi on the off road kit . Even if the 30 to 50 whp is for the 7psi kit...it still is over priced

I posted a thread about this a while ago with that link. They have more on it on their Japan site but good luck with translation LOL

Yes, it is a simplification but not so much as to not prove that an increase 50hp with a 7lb boost doesn't make sense. If you actually have an additional 7 lbs then there must be a addtional amount of fuel being burned to keep the fuel/air ratio correct. If you look at anyones measured hp and their boost there is nearly always a 7% increase per lb.
There certinely can't be more but any less shows some added inefficiency that must be converted into heat..... Just thinking out loud.... a quick calculation...
If you start with a 287hp engine and add 7lbs of boost under idea conditions you get an additional 49% or 140hp. 140 -50 = 90 hp wasted in heat. That is 90 x 746W or 67KW dissipated. Really there's no way that can happen and still be able to keep everything from melting. :-)
I'm not sure if that is a good argument but I have been keeping an eye on that rule of thumb for a while and it seems to hold up reasonably well. Something like 6-7% per lb .
Just my $0.02

as in... maybe the kit can make 500whp by turning up the boost...

I'm not really arguing with you, I mean this in the spirit of discussion. I'm a electronics type not car guy.
