We took a trip to Butler Performance to build the engine for Project Splitter , and while we were there, Rodney Butler showed us what he claims to be the highest horsepower Pontiac engine anywhere. It makes about 3000 horsepower with 2 91mm turbos and just under 50lbs of boost, but perhaps one of the most amazing parts is that it uses regular production Edelbrock Performer Pontiac aluminum cylinder heads! The same heads you can get in any high performance parts retailer can be massaged to flow enough to support 3000 horsepower with the right parts! The team at Butler have been building killer Pontiac engines for years, and they've got everything you could want to build a stocker to a Pro-Mod car. Look for the Splitter engine build on V8TV and this site soon!
