Who do you buy the modified cowl from?  Jim

 Ron:

 

 

 

 Let me clarify, the ceramic coated exhaust is not required with the BPE

 IO-540-X, it is merely an option.  The ceramic coating is designed to

 keep radiant heat out of the cowl (there has been significant discussion

 of this issue on the lists.)  We like the Forsling exhaust, because we

 have tested it on our dyno and found that it runs nice and gives a small

 hp boost on the engine we ran (a new IO-540-X with 9.5:1 compression and

 Barrett's Cold Air Induction.)  You can use any exhaust you choose.  You

 would only need the modified cowl if you decided to run our Cold Air

 Induction, which is a performance upgrade.  It is my understanding that

 the modified cowl is scheduled to be priced very similarly to Van's

 standard cowl.  The IO-540 without Cold Air does not require any

 modifications.  Hope this helps clarify.

 There's only ~$1K difference between the Vans and Aerosport engines, yet

 Vans is certified.  Why would anyone buy an experimental from Aero

 Sport??   What are the extra 'bangs' that you get for your Aero Sport

 'bucks'??

 

 The high performance BPA engine looks like a great package, but throw in

 the required ceramic exhaust and a non standard cowl and it becomes an

 expensive proposition.

Sam James is designing the modified cowl, and the first production cowl

is scheduled to be on display at OSH.

Does the modified cowl have a larger lower opening for the cold induction?  Thanks  Jim  I think it needs to be 3  1/2 inch diameter.

Jim, I just went through this as I've ordered The BPA IOP 540-X w/ 9:1 

pistons,  the CAS system, the John Forsling tuned Exhaust and the James 

Cowl/Plemmum. According to Will James, The modified cowl will have a 

different shaped opening similar to a 'smiley face' to accommodate the 

forward facing Barrett Cold Air Induction system. They pointed me to the 

eggenfellner website, and the posted pictures of their new cowl for 

their H6 engine. here's the link 

http://eggenfellneraircraft.com/100_1866.JPG.

Will has been working with Jan & co developing the new cowl for their 6 

cyl engine. He is currently working with an RV10 builder who is getting 

close to flying and Allen Barrett (BPA) on the Cold air mod, as I 

understand it they have already made at least one cowl that's intended 

to be a throw away just for test fit purposes. the plan is to have it 

all finalized by OSH and be ready for production cowls from final molds.

btw, the reports on the Forsling ceramic coated exhaust is that you can 

hold you hand within 1/2 to 1 inch of the manifolds on a running engine 

and not get burned. I'm hoping this will help with the reported tunnel 

heating probs, that appear to have their root in the heat build up that 

occurs in the Van's cowl. As I've recently learned,  the openings in the 

Van's cowl are soo large that more air  bubbles back out of the cowl 

around the prop than goes through the baffles and exits through the cowl 

openings in the bottom. It all equals a BIG amount of drag. All of that 

warm air bubbling around within the cowl can't be a good thing. The down 

side to the Forsling exhaust is that if you live in a cold climate (I 

don't,  it was 103 here today), you will have a harder time pulling heat 

off of the exhaust.

Here's another pic link of the eggenfellner cowl:

I also just remembered something additional that plays into this 

discussion, that the James cowl requires a 14" prop spinner.

I'm sorry I should have been more clear in my post. Will James is making 

the cowl for the eggenfellner H6 engine installation, it is specifically 

designed for that engine. The pictures shown are of an RV 6/7 I believe 

I have no idea what  Will is doing for that engine on RV-10's, I suspect 

it would be an entirely different cowl and would NOT be the same as an 

IO 540.  I only mentioned it as a reference to an inquiry about 

modifications to accomodate the forward facing Barrett Cold Air System. 

The eggenfellner cowl is an EXAMPLE of what the Cold Air system cowl 

will look like when complete for the RV-10.

The benefits to the James cowl/plenum are:

1. imporved cooling efficiency

2. reduced drag (their web site cites a 7-10 mph avg speed increase from 

their cowl/pressure plenum installation. This appears to be 

substantiated by builder results and air race results.)

The Cowl without the pressure plenum is only a partial solution. It's 

the combination of the devices that produces the above results

The cowl is made by James, I met him at Sun-n-Fun, and he said the RV-10 the

cowl for the Eggenfellner is basically ready to go.  I did not ask about a

IO-540 cowl.

Thanks for your reply.  Still a little confused.  If one wanted to purchase a modified cowl for a cold induction for the IO-540 for an RV-10 is there a source?  Thanks  Jim
