Arc aluminum billet duel bearing side cover worth 140$???

[Hoffman]

Is this kit worth the money?

If you're making big HP and are worried about block flex, sure

If you want it for the cool factor, probably not

If you have the money, go for it
can't hurt anything, right?

 

[Hoffman]

It does look way more cool but I guess the real big difference is the extra bearings. But how can you tell when to upgrade? When a better cam is installed?

On a fun kart, that may be the most pointless thing you could buy for the money. Those aren't needed unless you are racing at very high sustained RPM or making huge power. Now, it won't hurt anything having it, but it isn't necessary in 95% of the applications out there.

What would you define as "high RPM or huge power"?
Would you say anywhere between 8-10hp at 7-10k RPM?

You can buy the Raptor 3 cover (555209) for under 100$. when I was building B&S flatties for racing, that the one I used and never had a problem.

more like over 18hp and 8500-10,000 rpm

8-10hp on a clone isn't hard to get, its 9k rpm that takes work to get to.

I would say rmm727 has it said perfectly. My bsp clone makes over 10hp and it is doing just fine with the stock side cover.

What engine mods do you have now ?
