APBA – NBRA - AOF   Modified Outboard Racing

I stared building Mod engines in 1976. since then, there is no way to count the number of Championships the our products have won over the years.

WPT offers advanced cylinder porting needs. 2, 3, 4 or 6 cylinder engines.
Few have seen what we do for porting, even less will talk about it. They better not talk either!  But now, you can get the same work.  It is not as easy as you think and Mike has done this for years. All our porting is done on a vertical mill with digital readouts.
This ensures accuracy.  All other the hand work required is done with industrial porting tools.  Formula A to Formula E, Wienandt porting have won championships. 
We do not want to build complete engines for these classes anymore, however any machining you could need, we can do.

We can fit and finish your exhaust systems. We can design special exhaust systems for you.  We can custom build expansion chamber to your spec or ours. Check out our exhaust section

Connecting Rods can be resized for Mod racing and all our finish  Cylinder honing is done on our Sunnen # 1650
