Question Soup Up Mower Engine???

I've got your basic front wheel drive mower, with
a 5hp Quantum Briggs & Stratton engine. I've
replaced or repaired just about everything on this
mower except for the engine itself. The mower
runs almost like new, but I need just a little more

I have a fairly well equipped shop, so I thought about
fabricating some metal brackets and attaching 14-to-
16 inch wheels in the rear. This would (or should)
help me go up and down my lumpy and bumpy yard.

I know there are a million and one bolt-on parts made
for automobile engines that effectively increase
horsepower. Is there anything made for the humble
mower engine that wouldn't cost more than the
engine itself?

The large wheels will help on rough ground, like you said. As far as souping up a mower engine, it can be done, but the 5hp vertical engine isn't one to do it to. Performance parts are available, but they're for go-cart engines, and larger riding mower engines. Check your RPM's...if they're not up to reccomended specs, bring them up. That would help. What are you trying to cut? 5 HP should be substantial on a pushmower.
