Why spend $300-$400+ for a different high performance .21 engine when you can get the Hyper 21 8 Port Turbo engine for less than HALF that price!?!?

SPECIAL NOTE TO SAVAGE OWNERS: 

The Hyper 21 8 Port has the same engine mount hole pattern as the stock Savage 21BB engine.  This combined with the fact that the Hyper 21 8 Port and 21BB engines both have the same SG style crankshaft makes the Hyper 21 8 Port probably the easiest, bolt-in engine upgrade for the Savage!  Not only that, but the incredible performance and the low price we offer makes the Hyper 21 8 Port a great choice for your Savage!!
