The X3 will be based off of the N21R Limited with the same carb from the plus 4 and still in the same price range of the N21R.

The X7 will be a single exhaust port, 7 intake design that will replace the FMS and with lower transfer timing and higher blowdown timing, the engine will have more low end performance without sacrificing the midrange and top end side of the performance spectrum.

The X28 will be based of the older N528XR that was considered one of the best performing and reliable engines of their time and with the addition of the new style carb, it will have the long loved performance we have missed from the N528XR with the added tunability and run time efficiency we have come to expect and love about the plus 4.

I have personally run the older N528XR and I consistently was getting 9:30-10: 00 with the older carb so I can't wait to see what the new carb will do for the powerband and run time.

The X3 and X28 are available now and the X7 will be available at the end of the month.Feel free to pm or email me about engine pricing and custom modification services I will offer on this line of engines.
