Thats a sick setup! Considering meth?IHI vf39 turbo @ 18psi, sti intercooler, cobb tuning accesport, race headder including up pipe, cat less down pipe, aem cold air intake, and borla cat back exhaust. last time it was on the dyno it was at a lower psi and put down 325 whp which i did not think was that bad.
Nothing negative will happen unless the pump fails, that why the pricier kits have more failsafes in place that pull timing if it senses no spray.i dont think i will do that yet. what kind of performance would i get using meth and is there anything it would do to my car in a negative way? i was thinking maybe bigger injectors but i dont know if i need them or not?
