Default AEL75082 Piston Availability

The additional displacement (and HP) is accomplished by manufacturing the crankshaft connecting rod throws longer. Other modifications are incorporated to maintain proper clearances within the crankcase. Here is a list of pistons, compression ratios and rated HP for these displacement engines.

340 cubic inch (stroked 320)

AEL75412 8.0:1 +- 175 HP
AEL75413 9.0:1 +- 180 HP

370 cubic inch (stroked 360)

AEL75089 9.6:1 +- 200 HP
AEL75082 8.3:1 +- 187 HP
AEL75413 7.8:1 +- 183 HP

P.S. I am an employee of Continental Motors in Mobile AL.

Aviall currently shows no stock on AEL75082 pistons. Are these still available?

Default AEL75082 pistons

Yes, they are available. We have them in stock here at the factory in Mobile.
Aviall should request or we should submit that part number into their system. Do you need some ? I can be contacted at 251 436 8122

Just a question on octane ratings, I'm assuming the system of measuring octane is the same all around the world. In Australia regular unleaded is 91 with 2 grades higher before you get Avgas. The 2 grades are 95 and 98. That being so could I run 95 or 98 in a high compression 200hp engine?

Kit (rv7) arrives this weekend and engine choice is still a long way off.

Also my first post....

That applies to the usa. Don't know the Aussie systems.

Interesting the statement about the potential with mogas to have diesel mixed in, I have personal experience with that on my farm. I've got at least a thousand litres of mogas that I can't use for anything except cleaning parts.

Honestly, I didn't even read the article, beyond the essential point that USA mogas is an average of two octane rating methods vs avgas using one of them. Looks like it was basically a commercial for their octane measuring gadget.

I never worry about mogas contamination from the pump, other than checking each batch I buy for alcohol before using it in the plane. I *do* use a water/trash separating funnel when fueling the plane, because I do worry about my own sloppy handling. I can get 93 mon/ron E-free mogas in my area, and I've never had an issue running fresh summer blend in an 8.5-1 compression Lyc. (Winter blend in 100*F summer heat is a story for another day...)
