Since about 1993 I've run WildCat 10 or 15% fuel with 18% syn/castor blend. One Season I ran 6 gallons of PowerMaster 15% with 18% syn/castor blend. Last season I tried 4 gallons of WildCat 2/4 which has 18% synthetic. No I'm back to the Premium Extra with 18% syn/castor blend. On occasion I have run Fox 5% with 20% 50/50 syn/castor blend. It worked very well. I've never subscribed to the myth that Saitos need big nitro. They don't.
You are correct, Saitos don't "need" big nitro, but they will respond.
My high conpression CDI fired 180 W/the big bore carburator went from 8450 RPM on 15% Cool Power W/the 18X8 Dynathrust prop to 8850 RPM flashing 9000 RPM on 30% O'Donnell Speed Blend. It was kinda scary![X(]
While I won't run that fuel regularly, I will still probably juice it up ocasionally just for vertical fun in my Dynaflite PT-19. It only takes a small adjustment to the HSN to transition from 1 to the other.
BTW: That little experiment dispels the myth that CDI will not make more power W/higher nitro. Yeah right, tell that to the top fuel dragster boys!
