Custom HG for 86mm Bore Stroker?

Yeah, if you are running a 10:1 ratio, 91 octane should be fine. That's what i'm at, and it's also what MM recommends for their 10:1 ratio engines. 11:1 is where you really need to make the jump. Just make sure your chip is mapped accordingly.

BTW, I hope you were nice to Jim's wife when she picked up the phone. She makes an awesome breakfast.

Nice!

And I spoke directly to Jim. Awesome guy!

Does MM provide chips / engine management for these strokers?

Can't seem to find it on their site.

And MM does provide a chip for their complete engines. They use Mark D software and write the chips custom for their application.

to get the most out of the engine you're going to want more than just a chip if you want to get every possible HP out of the motor - MM is great, but their main goal is stock reliability with a bit more power, not neccesarily all out raw power. So they tend to be a bit conservative (like with their cams). A chip for the stock ECU is a great place to start though, and a safe way to break in the motor without worrying about the tune too much.

I totally agree. MM is based on reliability, not guns blazing power. The M20 in my car that they built is an amazing DD engine.
