I was looking into getting one of those rev box limiters that increases your rev limit on the raptor by about 1200 rpms. Are these things safe? Do they make your bike a little quicker? Has anyone used one before and how do you like it........[img]i/expressions/face-icon-small-smile.gif[/img]

 

You are gonna need a monster aftermarket cam to be making power above 9K rpm's. The stock cam peaks around 6.5k and drops off after that...so it makes no sense beating on your engine for even less power. The Raptor has been known to blow stock rods as well under more pressure than stock....I would certainly consider another 1k rpms a lot more pressure.

I just ordered one, I havent gotten it installed yet. Check my sig for my mods - when I install it ill let you know the results.

 

The stock CDI had a good 1K+ overrev with the stage 1 Hot Cam. If you use the overrev of the new CDI, you will actually be loosing power over your current configuration. The quickest way from point a to point b, after proper gearing, is shifting at of slightly after peak power....not 2K after your power peaks and you loose 15hp (example). You will be no quicker, just beating on your engine. Everyone stopped selling the advance key for the Raptor because the results were not really noticable, so thats not an arguement either. Gary

 

So if all I have on my Raptor is K & N filter, jetting and pipe, I should not get the CDi rev increaser? Or should I just stay away from it period?

 

Stay away from it period IMO. Lokk at just about any dyno for a raptor. How much power do they show it's making at 9K rpm? After a certain point the power starts to fall dramatically, so basically if you follow the direction the power is going and just extend it by another 1k rpm, you will be making less power than you were at 9k rpm. Personally, I would feel a little uncomfortable revving my engine an extra 1K rpm just so I could make less power. Have you ever hit the rev limiter before anyway?

No I dont ever hit the rev limiter, i was just going on what some friends told me. my buddies put those things in their honda 400's. however i was a little skeptical and i didnt want to raise my rpm rate and damage my engine.

 

If you don't even get to 9k rpm, why would you want to be able to go to 10k rpm? You see where I am going with this. Spend the money on something that is more useful.

I got the box to gain more control, not having the bike limit me. I do a lot of huge hill climbs, I want the little bit of overrev. You cant always upshift in the middle of a climb.

Do you have to rev up that much.....no. But its nice that if you need to you can.

 

Well you will find out if you like it or not. But for the money you could of just about purchased a cam and installed it your self. If you don't like the cdi save it for when you do some motor mods, then try it again.
