Based on Fuel Flow and performance I would estimate between 170 and 180 HP on a normal day. It does considerably better when it has cold dense air and I have seen fuel flow of 21 GPH on a cold day.
I guess we’ll just have to get Mike and Tracy to do a fly off {:>). I do know the three rotor is capable of around 300 HP without a turbo – we’ll have to wait and see what Tracy gets out of it, but I would be very surprised if it isn’t at least 275 -280 HP range.

Thanks Ed, sorry I couldnt think of your name. I remember yourr storyu about your long dead stick landing a few years ago. How many HP does your rotary have? Aslo Do you know how Tracy's engind stacks up against Mikes 540 in his super 8? Charlie Heathco

No 21 Gallons per hour fuel flow on a cold morning. Normally fuel flow on max power take off on a nominal day is around 17.5 – 18 gph..
Yes, I believe that was the Powersport FWF package of a modified Mazda rotary engine. It reportedly produced 215 HP with a racing type Peripheral port intake, but I never saw fuel burn figures. There were two in Rv-8s – but, it was pretty clear these guys did not know how (at least at the time of the test) to properly lean a rotary for best economy – you can not hurt the rotary by leaning it too much – the power will decrease due to the lesser fuel flow but that’s it. I lean my rotary during cruise so much that the air/fuel ratio indication runs off the lean end of the scale.
But, with the newer Renesis Mazda engine the fuel and power are incrementally better than the old 13B model that I fly with. However, we are all waiting for Mazda to bring out their completely new and larger 16X which they have shown and has been reported on. It will be approx 30 lbs lighter due to them switching from iron to aluminum side housings and will produce approx 30 -40 more HP than the current model. So 30 lbs lighter and 30 more HP should really make a difference. Now If I only live long enough to see it appear {:>) – it’ll probably be the last major change to my installation.
Best Regards
Ed
