It is pretty well known in the industry that it takes about $1000 cost per knot of aerodynamic speed gain (actually it is not anywhere near a linear relationship). Sounds like Gary's cowling will fit into this ballpark pretty well. BTW, have you price cowlings for other planes lately? See how much a new lower cowling for a new Tiger would cost!

That includes 5 different designs. Still going after another few knots. ________________________________ Message 5 _____________________________________ Time: 08:43:25 AM PST US From: "flyv35b" Subject: Re: TeamGrumman-List: Re: TeamGrumman-List Digest: 1 Msgs - 01/28/05 --> TeamGrumman-List message posted by: "flyv35b" I love it (the comment)! ----- Original Message ----- From: Subject: Re: TeamGrumman-List: Re: TeamGrumman-List Digest: 1 Msgs - 01/28/05 > --> TeamGrumman-List message posted by: TeamGrumman@aol.com > > > In a message dated 1/31/05 12:44:07 PM, bhauskne@san.rr.com writes: > > >> Wow!=A0 $7,500 for a fiberglass cowl and $8,500 for carbon?=A0 >> > > You could always spend $3,000+ for the LoPresti nose bowl, not go any > faster, > and have the same cooling.

Can't wait! Probably won't enter the race, because my Tiger isn't really competitive at this point (yet, first year with it and just starting the improvements). Heck, it still has the McCauley prop. So things like new cowls are a year or so away. Probably long enough for you to perfect your cowl and have some ravid users. See ya there.
