I don't think Bill has a web site believe it or not.- I do think that he did some advertising in a recent Red Star newsletter though... you might as k a member.- He is also offering a new exhaust design that basically is d esigned around single tube header//collector concept from race cars.- In fact I think his whole approach began from that starting point.- I have s ome experience with drag racing engines and his mods have the look and feel of some of the same things done to typical race engines.- The Russians u sed loose tolerances with rings that hopefully would expand and seal once h ot.- They do actually.- Bill's approach was to use a slightly higher co mpression piston, which I think was something around 8.4:1 or so, then re-m achine the valve guides, then use closer tolerance pistons with the gapless rings.- Just with the pistons, you could probably expect a 20 HP or more gain on a M-14PF.- With the new exhaust system, I would expect he is getting somewhere near 430 HP or so out of a M-14PF.- Tom Johnson also m oved his oil cooler to the wing root.- His airplane is simply over the to p.- His engine was a prototype for Bill's mods, he has the MT FW-190 blad ed prop, he had CUSTOM tube headers installed and they are simply just GORG EOUS.- I have no idea what his engine puts out, but it's dramatic.- Tom is good friends with Bill Blackwell... suggest you talk to him personally. - =0A=0AMark=0A=0A-=0A=0A=0A=0A________________________________=0AFrom: Hans Oortman 1 =0ATo: yak-list@matronics.com=0ASent: Su nday, April 26, 2009 3:52:22 PM=0ASubject: RE: Yak-List: What is your typic al oil consumption?=0A=0A=0AMark,=0A-=0ASounds like a very interesting mo d.=0ADoes Bill Blackwell have a website??=0A-=0AHans=0A-=0A=0A_________ _______________________=0A=0AVan:owner-yak-list-server@matronics.com [mailt o:owner-yak-list-server@matronics.com] Namens Yak Pilot=0AVerzonden: zondag 26 april 2009 21:35=0AAan: yak-list@matronics.com=0AOnderwerp: Re: Yak-Lis t: What is your typical oil consumption?=0A-=0A1 quart = 0.946 liter . - My M-14P has burnt about 1 liter per hour since new.- Every M-14 (exc ept for one) that I have worked on burnt that much or more.- Nothing wron g with that amount of usage unless you see it leaking out all over the engi ne compartment obviously.- I have been told that filling the oil tank all the way to the top and then doing hard acro is not a bright move as it wil l spew oil everywhere.- I have found personally that this seems to be tru e, especially with negative G stuff.- When planning that kind of flight, I usually plan on having a total of 9- 10 liters showing on the stick (thes e are short flights and the oil is checked after each flight).
