Product Description

The RMRE Super Series 665° Raptor All Aluminum engine combines the raw power of big cubic inches with light weight construction for an incredible package. The advantages of the 12° Raptor heads, and numerous other performance upgrades become obvious when the dyno needle rips past 1,020 Ft/Lbs of torque on the way to 1,340+Hp. This is big time reliable power!

NOTE: Tests were performed with NON-OXYGENATED fuel. The use of OXYGENATED fuels (Example: VP113 or Q16) may produce a power increase, but will require a tuning change, including increase in jet size, for optimum performance.

This engine is available with nitrous for even more power!
