So, have spent hours searching for pics of vans stock cowl, modified for BPE IO540 with horizontal induction. Really would like to get into this engine, but a bit scared of the fberglass work. A part of me wants to push the easy button with a vertical, but the cold air induction is enticing.

I've seen some great mods of the Sam James cowl - Deems, you're amazing!- but I'm hopeful that the mods to a stock cowl would be less involved.

Sounds like there are a lot of these engines out there, but not much luck on pictures. If any of you guys have done this, can I get some pointers?

Thanks!

Phil,
Very little fundamental difference in modifying a Vans cowl or a James cowl. The stock cowl is a honeycomb and thus may need core hard points here and there. I suppose you could argue it makes the stock cowl harder to modify, but I don't think it is a big deal.

Going with a horizontal manifold means using a snorkel from the left cooling intake, or using a forward facing scoop through the cowl. I assume you're thinking about an RV10, so you may want to contact Rod Bower regarding one of his scoops for the -10 cowl:

The obvious alternative is to build whatever you want:

thanks Dan, this is what I was looking for. Amazing how many permutations of a search you can do and not find what y ou want.

It hadn't been clear to me whether Rod had things worked out for the standard cowl - i'll check with him
