2019 Grizzly 700 EHS Racing Camshaft Testing with Big 3 Duals Package EHSRACING Custom Cam 

I believe that factory Hp for the Brute Force is 50Hp Factory for the griz is 47Hp (at the crank.) What They're measuring on the Dyno is to the wheel. It's more like he's putting you into the low end of the CanAm power levels. (but with less weight) Just like you I'll probably be buying this kit too. 👍

No 800. They'll get smoked

Talked with him a couple days ago about reliability. I don't live near them so I won't be dropping it off I have to do it myself. But basically versus stock he figured it was more reliable. Basically gets rid of a weak point and that is the piston that he said Yamaha has gotten cheaper with over the years. The airbox mods fix dust leaks, the piston upgrade fixes that weak point and the cam isn't gnarly enough to add extra wear and tear. I'll be picking up my kit this summer.

Their website sucks ass. I hear you need to call these dudes. He needs to hire a web developer or have someone manage his parts inventory. I would like to see how HotCams work out.

EHS doesn't offer anything to do that. There are ways. But everything I've read up on it is that it's pointless. With a normal transmission you want to over-revthe motor so that when your shift go right back in the power. This is not necessary with a CVT. You want to get to max power output rpm and stay there. Rev-ing to 9000 like the raptor is not necessary, and would probably be slower. The only reason I was looking into it would be for higher top speed. But then I found out with a mild about your build you can already go to bed 70. People often door because the motor stock run to the power to push you like best in people talk about somewhere in the mid 60s. Is there some reason you want to go 80 to 100 miles an hour on the quad. And that is a promise to take it. You should be able to find it with a search. I did.

I'd really like to know that too

@@kiddydiddlerchristian4124 Hopefully he'll comment back, I know if it was me I'd be bore it to a 727 and up the compression. I had a built Raptor that made some really good power and those were two things I did. The compression I bumped up to 14: 1 but that was running race fuel, if I was to buy another grizzly and do similar mods I'd probably only go to about a 11: 1 compression.

stock bore mild compression increase its mainly for a better forged piston and ring setup. the pistons in the newer bikes are not quite the same quality as the old yamaha stuff. Then tend to wear out much faster. the compression gain helps some but we do it mainly for a more solid built motor.

@@EHSRACING Why not do a 727 while your changing the piston? And what do you feel is a safe compression bump if running 91 octane?

@@EHSRACING I haven't heard of this piston issue, how much of an issue is it? is the piston really necessary? What piston and cam did you use? What are your thoughts on Webcam cams? (FYI your website lists a page for cams but it's blank) Looks like i'm upgrading to a new grizzly soon..... looks like i'll have to buy some new toys from you again.

Still around and great as always. Talked to him yesterday, Ordering a cam for my 08 700 from him on Monday. Would of today but not open weekends.
