Wanted, something in a .51 size for a Sig Magnum
« on: August 26, 2021, 07:51:57 PM »
Hi everyone, I am getting ready to build a Sig Magnum, and I am looking for an engine. I am thinking of something in the .51 range, since I have a tendency to build a tic heavy. TIA.

Hello,
I would recommend a Randy Smith Magnum XLS 52 ABC along with a tongue muffler, very nice running engine with great power and not as thirsty as an old ST 60.  It has as much if not more power and lighter weight.  Great combo that will serve you well.

Later,
Mike Pratt

Randy Smiths Magnum 52XLS is a fantastic engine. More than enough power for a heavy Sig Magnum!

The problem will be if he has one, or, if he can find the necessary materials to make one.

Good luck.

Craig,
I’ve built no less than eight Magnums with the heaviest being 60 ounces with a ST 60.  The kits builds at a reasonable weight, it’s only the builder that makes it heavy (like most kits).  When you think about it, a 60 ounce 700 sq. in. model is quite good, I’m thinking that with the modern engines it would be easy to build in the low 50’s with out much trouble.  Yes I’ve heard of people building them really heavy 70 + ounces but ive never built one that heavy, I think you have to try to make it that heavy.
