My lawn tractor is only 14hp and pretty much stock. I did put a K&N on it, not cause it needed it but so when I'm standing around drinking beer with the neighbors, I can say...."Yep, she's got a K&N on her". I wouldn't win in the grass cutting category but I may have the fastest blender. Shes got a 2-stroke gas engine on a custom frame and will knock out some margaritas.

 

Well,truck,car,boat,quad........you can make anything fast if you are willing to invest the capital into it.
I could make Windsor Castle run 10's with enuff money.

I keep looking in the classifieds around here for a catapult from the deck of an aircraft carrier.
Someone's gotta have one for sale someplace.....maybe check ebay.
Everything I own will be fast then.........hahaha
