Yeah I know I'm pretty limited.

Theoretically though...at 80% duty cycle and 43psi pressure, I can still achieve just over 220hp at the wheels (using 15% loss for FWD drive train). That's starting to push things though, and if your gunna go past that with injectors, it's gunna get risky. I am however using a rising rate pressure reg which I saw get up to 60psi on the dyno, so maybe that will get me 225Kw leeway. But yeah, I'm only interested getting 200 on paper (soo close with 197.8 :x ), so now I'll save some biccies and do the other mods already mentioned as well as some 550cc injectors.

Personally, with a little bit more boost, I think I can get 205hp, maybe 210 if I really want to push my luck (which I don't ops: ).

There is a dyno day coming up that Im going to attend and see what I can get where I can really monitor what's going on more closely.


Turbo Mazda, what's some more specs on your car?? ECU, turbo, pump, etc etc. Hows yours on daily driving with fuel ecconomy? That's my main concern with going to 550's.
