Boyesen RAD Valve review, genuine ass-dyno numbers

[super noober]

well my man slickerthanyou hooked me up with a RAD valve to try out, so i though what the hell, ive always heard they suck but ill try em. so i finally got them on today and i have to say WOW, amazing difference in throttle response, revs up quicker and higher than my stocker. AND there is room for improvement because there is a lip that i could bore out to make everything nice and smooth. i MIGHT have lost a tiny bit on the top end but it very hard to say, but i KNOW i gained a ton of low and midrange I:I. so im gonna go ahead and put it out there and say that i dunno what kind of crap test they did bad on my ass-dyno is telling me that if you can pick some up cheap i would go for it I:I I:I.

Haha yes it does. I'd like to see a dyno comparasion between all the different reeds, like vforce, boyseen, pyramid, mossberger.

I'd like to see Ken match a rad valve to one of his port jobs. I believe there's more in a rad valve if a good builder worked it over. I've messed with grinding on them in the past on YZ's with some success and I ain't good...LOL

i agree 100%, there is a good sized lip where the stock intake and rad valve meet and it still is quite impressive. i imagine if it got smoothed out nice and flawlessly... ohhh boy lol I:I I:I

Then he can use his ass dyno to measure performance gains.

thanks man!! im not going to rip it back apart immediately but im going to redo my plastics before busco so i will hog it out then lol. for straight trail riding its amazing, im not trying to say they are the greatest thing out there, (ive never tried vforce or pyramid), just that they are most definately not garbage like mayor mccheeseburger had everybody convinced. and the gains were quite impressive I:I I:I

 

[slickerthanyou]

Mayor mccheeseburger? HAAAAAAAAAAAHAAAAAA I thought more like grimmis (SP?).
Noob ya did do a leak down test I hope-Please!!

Freek lets see some pics. I'd like to see what can be done.

 

[blasterfreek30]

[blasterfreek30]

[super noober]

veeeery nice, i didnt realize you could open it up so much. gonna have to do that before busco! I:I I:I I:I

 

[brandoz28]

man, i think that batt might have a little bit of a future in the porting thing....the work looks nice, now gotta get him workin on his math skillz lol

 

[slickerthanyou]

Holy chit batt-man. Now that's a port job! Looks great-How the heck do ya get that little port to open up that big?

 

[battbike]

[brandoz28]

are those the same ones you used to do the cylinder too?


work looks awesome btw

 

[battbike]
