RE: Finaly I did it ! I build my wren !!
Hi, from what i understand from WREN the MK2 kits are good for a solid 12+ pounds of thrust and the MK3 kits are good for 14+#s of thrust. It all depends what combustion chamber,diffuser and tailcone that you have. The mk2 have the new diffuser and one piece tail cone, the mk3s have the new diffuer, chamber and 2 piece tail cone. To confuse things more I think that there are some mk2s with 2 piece tailcones. As they discover improvements they add them to the engines so it is a constant state of evolution. I have a mk3 (new diffuser,chamber and 2 part cone) and get about 14.2 pounds thrust at 160k. Scott
