Well, not all my ideas work so good.
The Lambo Jalpa airboxes fit GREAT, but the forward one is too tall and the bonnet cannot close. The metal support beam in the bonnet contacts the box and prevents from coming all the way down. Back to Ebay for the boxs probably.
Not to be dissuaded, have designed a possible solution and will go to an aircraft a&p fabricator tomorrow. Here are the issues to solve for making this worthwhile to me:
1. One plenum per bank, easily removed and giving quick access for carb tuning and work ( where you don't have to remove the whole assembly like stock)
2. More open than stock allowing more airflow between the carbs to allow cooler running temps and solve intermittant fuel system heat soak problems I've had here in Texas.
3. curved plenum top like all 348 and after dual plenumed Ferraris
4.Offset side box with flow taper to better aid even flow and enhance flow velocity to carbs and mixture stability barrell to barrell using the Jalpa offset scheme and add a front to rear taper like in older Ferraris and some others.
6. Simple
7. Use/modify existing adapter plates ($)
8. Adaptable to readily available K&N filter set up.
9. The bonnet must close
Have enclosed photo of the Jalpa airboxes installed just to show you what they looked like on a carb Ferrari engine. I think they would have worked pretty well. Also shown is a picture of the adaptor plate showing how easy it is to work on the carbs once the airboxes are quickly removed by six nuts, and my current best attempt at a solution.
I apologize that the engine is so dirty - I've been driving it a lot in the rain this fall/winter and need to do a spring cleaning. It really does clean up nicely I promise.
All ideas and comments welcome. Hope this is interesting for the 3 guys left following this.
best
Russ
