We have not yet bought a motor but we are considering the superior xp360 injected version. It is a parallel valve with a vertical induction. My question is how much drag does the chin scoop create with the vertical induction? Does the slight boost from the ram air on a chin scoop version outweigh the lack of drag from a non chin scoop cowl that is used with horizontal induction? Does anyone have any hard numbers to compare the 2 cowl versions?. I think the xp360 can be converted to a horizontal draft induction but is it worth the bother? Any comments would be appreciated. The bottom line is given the same motor which cowl is faster, chin scoop or non chin scoop?

I ordered 2 seat heaters from Smarthome. I'll let everyone know how they work whenever they get here. Supposed to ship mid- February. I plan to cannabalize them and install them in the Rocket seats. Should eliminate my concerns about not having a rear seat heat duct. That Canadian Tire store must sell everything! Thx, Vince From: "Norman" Subject: Rocket-List: Electric Seat Makers --> Rocket-List message posted by: "Norman" Want heated seats right now for $30 USD? Check out http://www.smarthome.com/9290.html if you have a spare cig lighter socket to plug it in. They are seat covers that you can put right on top of your seats. I think some one could take a pair of these and some foam and have the wife sew some fabric to the sides and bottom making them into custom heated seats. What do others think? Canadian veiwers can get a product very simular at Canadian tire for $80. Go figure. These guys are making a simular product for $50 http://www.skingcompany.com/index.asp#Heating+Products goto heating products ________________________________ Message 3 _____________________________________ Time: 07:42:17 AM PST US From: CalBru@aol.com Subject: Rocket-List: (no subject) --> Rocket-List message posted by: CalBru@aol.com Does anyone know what happened to RocketBoys web site, sayes that it is closed? ________________________________ Message 4 _____________________________________ Time: 07:52:15 AM PST US From: "Ron C" Subject: RE: Rocket-List: Vertical or horizontal induction --> Rocket-List message posted by: "Ron C" Shane- On my harmon rocket with an IO-540 direct ram air induction nets about 1.2 in of manifold pressure. On a 250 hp engine this is around 10 hp! It is not the aerodynamics of the cowl I am speaking of but the ramming effect of having the throttle body facing directly into the on coming airstream that makes the difference. When I switch from filtered air(which draws through a foam motorcycle filter inside the cowl) to ram air I can see the increase on my digital mp gauge. A friend with another rocket switched to the direct ram air induction on his plane after flying with the typical vans/Rocket filter duct induction and saw the same mp increase and corresponding speed improvement. You can buy a 90 degree induction elbow from John Harmon for less than a hundred dollars if I remember correctly. Call me if you want to come by and see all this in the flesh on my rocket.
