//NHRA LEGAL PRO MOD

DESCRIPTION:

MBE set the drag racing world on its ear when it introduced its Top Fuel and Funny Car competition cylinder heads. That cylinder head design was so dominant in competition that it actually caused the NHRA to change the rulebook.

And now MBE has taken everything it has learned racing that head and used it to create its NHRA Legal Pro Mod cylinder head. Like its Top Fuel big brother, the Pro Mod head gains an advantage on the competition by utilizing ultra-efficient intake and exhaust ports. The combustion chambers utilize a unique design to allow large 2.400-inch intake valves and 1.900 exhausts without shrouding. As a result, these heads feature class leading ports capable of flowing an astounding 556 through the intakes and 396 out the exhausts. That’s 40 more cfm through the intake than any other Pro Mod cylinder head currently available! And remember, MBE is the only induction specialist willing to stand behind its advertised flow numbers with a money back guarantee.

Many feel that perfect ports aren’t important when you can simply bolt a giant supercharger on top of your race engine, but MBE has proven that simply isn’t true. By moving air and fuel more efficiently, these heads actually lower the boost pressure by three pounds. As a result, teams are able to make passes with less ignition timing and a lower blower overdrive ratio. This makes the engine more predictable while still gaining around six miles per hour at the finish line. Plus, engine durability is even improved!

So for Pro Mod racers looking to gain a competitive edge on the race track, the new NHRA Legal Pro Mod heads from MBE are practically an unfair advantage.
