650whp on PURE600s possible??
recently heard someone on fb saying they were hitting 650whp with PURE600s on E85 with PI at 28-30psi - is this possible? i thought these capped out around 550.
should i consider the PURE600s if wanting to hit around 575-600whp on pump gas + PI + meth with stage3 lpfp + rest of supporting mods. will it be safe for the turbos? how much psi? back pressure an issue? (have external PCV + alum. valve cover)
if anyone has a dyno sheet of the pure600s on pump gas+meth hitting close to 600whp please share, thanks!!
