REW based Single Rotor (hereinafter called a WL which stands for "Wun Lunga" - One Lunger -  get it?? - obtuse Oz humour!) 
 
A new tail number is born!  N654WL   I was planning N654SR, but Sierra Romeo doesn't sound as good as Whiskey Lima.  Either way, I have to explain it.  I could just announce myself on the radio as 654 Wun Lunga (in my best Paul Hogan accent) :-)

Well,  I just might have to see if I can get VH-MWL (Mazda Wun Lunga - aka Mike Whiskey Lima for my amphib!).

BTW,  Paul Hogan is passe these days.  King Billy CokeBottle is better!  He's a real indiginous Australian (aboriginal) person,  and a great comedian -
 
 
it's not THAT much slower than a stock 12A twin rotor engine in the RX7.  Bit sluggish low down,  but once it gets up to 3 grand,  it really gets it's rocks off.  
 
Very cool, but hard to believe anything is slower than my old 85 RX-7 was :-)  I was the most fun car I've ever owned though!

Well,  most of the RX7's I've driven over the years haven't really been slugs - for a standard car that is.  As mentioned, Humphrey IS a bit of a slug off the line (could do with a heavier fly wheel),  but he really starts to hoot once the WL gets "on the pipe" above 4,500 RPM.  I haven't given it a real pasting yet as I want to run it in carefully for a couple of thousand km. 
 
But as you say,  RX7s ARE fun cars.  This one has me in a constant state of mirth - I just LOVE the look on peoples' faces when the look in the engine bay ..:
 
Price of ULP today:  $1.25 per litre
New RX7 gearbox mount:  $ 49.63
Fine for exceeding the speed limit by less than 10 KPH:  $75.00
Looks when people see an RX8 Wun Lunga  in Humphrey's engine bay - Priceless!
 
So that's the "State of the Nation" Downunder as far as Single Rotor development is concerned.  Two engines,  one based on a 13B REW (which has already run faultlessly for several thousand Km last year),  and another based on Renesis RX8 parts - both successfully running with NO problems.   
 
Any significant weight difference between the REW and Renesis versions?  It can't be much.  Will you be able to tell what (if any) the power difference is?  
 
##
Probably under 3Kg - I've just posted that info to Finn in another couple of emails.  My next trick is to see if I can fit up a Renesis front cover mit water pump to the earlier engines.  That WOULD be flash!
 
Cheers,
Rusty (did I mention- very cool!)

Thanks for the compliment!
