RE: Super Tigre Blue Head Schneurle .40
Outstanding figures David!
15K it is!
From the stock muffler at ~13.5K gaining almost 1.5K on a pipe is impressive!
I'm glad I didn't decide to retrofit the Tsunami for a YS 45. Although speed is fun I'm also curious about how she'll stand up to higher loading - an 11x5. I think I'm going to do the final push on the Tsunami this week and get her ready for takeoff. Beforehand, some testing of the bluehead will be required. It'd be nice to have an APC 9x8, 10x6 and 11x5 on hand.
What's the length of your header at present? I'll cut mine 1/2" longer to try out the 11x5 for a starters.
BTW, do you have the conversion formulas for thrust, hp and pitch speed or does the Fromeco do all that for you? Iguess pitch speed is easy to convert from RPM.
David.
