25-30 hp if the heads,exhast, carbs,and intake were done right??29 cubes is pretty small v-twin.Building a 30 cube vanny now and hoping for at least 30 hp.

 OK.

 We do not hawe a lot of rules in sweden regarding lawn mower racing.
 We hawe wery simple roules.
 Klass 1 : Lawn mower with maximum 13 hp mower engine with free tuning. But no turbo charging or supercharging .
 Klass 2 : lawn mower with maximum 23 hp + free tuning. No turbo or boost .
 In booth klasses the mower is not alloud to be wider then 1.05 meters and not longer than 2.2 meters.
 Free modifikation to the chassy.
 Stif mounted axels.

 We hade a race on asfalt last week. The red camouflage traktor is mine. its a klass 1 race. I have a 13 hp OHV briggs with home grinded cam, ported head, homebalanced crank .

 You canb se it on youtube here.
 Video not sutable for Heymow.

 Easy and simple.

 In my oppinion big engines do not like high rpm.
 Therfor I want to prepare a small vanguard for racing. Like the 30 ci vanguard. I think this engine can stand easier the high RPM-s compare to the 35 or 40 engines.
 Am i right ?

"last" is the key word. They may SURVIVE at 10,000 rpms plus...but don't count on them LASTING. Count on very regular servicing...and frequent valve spring valve guide and valve replacement.

 1 more question about this engine.
 What is the safe and highest  RPM for a standard vanguard 30 CI engine without the governor ?
 Its not the "black" vanny. Its a older red vanguard yet still made in Japan.
 Is it OK to run the engine at 5000 RPM without any problems, or should I go below 5000 or iīts OK with 6000 ?
 What is your recommendations ?
 
 One modification to the engine will be made. The flywheel . I will order a ARC flywheel. Thatīs it. the rest of the engine will be stock
