Max rpm GS-45
Hi guys,
Need some help here. I have a Supertigre GS-45 it's a little worked over with a jett pipe and carb "way good carb", spins 15500 on the stand with a APC 9x9. Crunched the numbers with a web calculator and its right around 1000 watts..... But of course I need to go faster.... minus the plane...haha it's some 130ish mph. So, I've been looking at different props. Calculated off my base line, 8.75 x 9.5 = the same 1000 watts and a 145 mph, just a slight rise in rpm 16000.... the limit according to the supertigre manuel. Ok?...?... So using that same cuuk'o'later... If I go with an 8x9.5,8x10 or 8x11 I'll really be singing 170-185 mph at around 1100 watts. BUT 16500 to 18700 rpm... Does anybody know how fast you can spin a GS-45 befor it goes into self destruct mode? Also, I think APC makes an 8x9.5 and an 8x10.... anybody know who makes an 8x11 or even an 8x12? In case you all are wonder... I'm stuffing the little beast in to an wildhare LR-1. Mawhahahahhhaa "evil laugh". [sm=devious.gif] Thanks.
