alright i have a new s4 rebuild with s5 rotors, a gasket matched lower intake(base manifold), removed 5/6 port sleeves, RB header with strait through 2.5in exhaust, tb mod, cold air intake, 550cc secondaries, all smog stuff removed, removed ac and ps, all cats removed and i think that might be it.. i am figureing around 175hp at the wheels bc the stock numbers were 145hp at the wheels so i think my mods would take to around 175hp.. does this sound right?? i just dont know where to shift for peak power and porformance. all the help appreiciated

goodness man, I would say somewhere around 7500-8000 rpm. I bet you make nice power up there too!

 

Yes, that puts you around 190-200 bhp... same as me

You should really use the search function.... see my old thread : https://www.rx7club.com/forum/showth...ighlight=shift

 

well i shift my 91 at 6.5k-7k when i race. i dont like to redline to much. but if you are talking about chirping tires shift around 5k but if you are racing take it to 8k i shift lower cause i have low compression and i dont want to risk anything

 

hmm 8 k not yet.... i would try and get an 89 up intake mani and slap it on there that would really help being you got the s5 rotors good setup man
