and I would add to read the fine print on those warranties. MOST warranties do not cover things that happened during say "spirited driving" or "competitions". I don't know what Blueprint engine's is though. But just read carefully
Edit: I found BluePrint's warranty disclaimer and terms.
Good point. It's understandable that they wouldn't cover people adding boost to a motor...but their use of "racing application" seems to be open enough to interpretation.
Honestly, if I blew up a motor by doing something stupid, I wouldn't try to get someone else to pay for it...but if the motor chucks a rod on the drag strip while being operated within safe AFR/RPM ranges...but they would cover it if you were just ripping around on the street, it would be shame if they denied that claim.
