True but the fuel burn will go WAY up....I think speed is proportional
to power cubed (or is the squared?) ...Anyway lets say you do 125mph
(WOT) on 8GPH right now...Well you 115mph is around 5 GPH correct?
Do you really want to almost double your fuel burn for another
10mph?...Not worth it. On cross X you will be landing much more often
that your door to dorr speed will be much higher by flying slower.
Where 130+hp will benefit is doing what the 601 does pretty darned well
already...i.e...CLIMB!
A much better benefit would be to look at closing down the cowl openings
(almost redundant in the Stratus intallation anyway) to reduce the
cooling drag...That way you get hopfully some more speed with no extra
fuel burn.

I'm sure you are correct that the HDS will not go faster than what ZAC
has said it will. Problem is, mine does about 115 mph cruise (on a god
day) and ZAC had always advertised I think in the 130 mph range. If I
could get mine to go that fast with a 130 or so hp engine, I think it
may be worth it (especially if the engine weight remained the same).
Regards,
Bill

Hi guys,
Is anyone using a spark plug other than the standard specified
NKG BP6ET for the Stratus EA-81 for the purpose of lowering
their EGT? A short piece on the internet suggests that various
plugs provide differing effects on exhaust gas temps. Not sure
how to read that either way, but if anyone has input
on plugs, I'd like to hear about it.
