Wow! Very impressive numbers
I was pushing 20psi to get 307 rwhp (Dyno Dynamics Dynometer) on my 1.6 while you are almost there with 5 less psi
1) What did you do to use less boost for almost the same power?
2) Someone mentioned that the 6spd g/box is good for 400rwhp.
What are the facts for this based on?
Does someone have 400rwhp & a 6spd g/box? Anyone?
jtothawhat - I hope I haven't hijacked your thread in anyway
1. Well i dunno what turbo you where running but his is sizeable this freed up more hp per psi becouse he was getting a cooler denser charge pre IC.
2. Miata 5 speeds have case flex and gear issues man we flex the case and breack the gears i know my bellhousing has numerous stress cracks in it. And the 6 speed uses stronger gears and a stouter case. I have seen on here and other sites of people running 400 and even into 600+ hp on them and working fine.
