I'm doing a cam change on my stock evo with a SE a/c and V&H fuelpak with fuel injection.Which cam would you guys recommend;Andrews EV23 or Ev27?

 

Well, I have an EV27. I have not installed it yet but the reason I bought it is because so many people raved about it. I would suspect you'll be quite happy.

 

I'm just torn between the two.What are the pros and cons?

 

I think that the two most commonly used "street grind" cams offered by Andrews are the EV13 and the EV27. The 13 gives more low end power through midrange without increasing the "redline". The Ev27 starts more in the midrange and allows about 500 rpm increase at the top end. This info is available on Andrews website.

 

I used an EV27 in my FLHS for several years. If I was to fit a cam these days I would probably chose the EV13.

There has been a similar question on HDF recently, so use search to see the replies there.

 

If it's for your bagger, Id use the one with the better low end grunt. I love the EV27 for softails (lighter bikes) but you need the extra torque to get a bagger moving.

 

I run the EV27. I have no experience with other cams in the EVO motors. I agree,however,in a bagger you want good torque!
As far as the 27 goes,I LOVE IT! I crack that throttle and it just pulls harder and harder through the RPMs!

 

go with the 13 do not use the 27 or anything else that has an intake close of 36/38 or higher UNLESS you plan on having good back pressure in your exhaust and a high flow intake (think two into one exhaust with baffles) If you are running open pipes, it will be pretty poor performance below around 3200 to 3800 rpm...

 

So the EV27 is bad for a bike with drag pipes? I of course run 40 inch drags. Are you saying the EV13 is a better cam for a stock motor with drags?

I was also under the impression that the EV27 was invented soley for use in heavy baggers and made phenomenal low end torque, and just happened to excel in lighter bikes as a happenstance to the fact it was so well designed? Please fill me in here before in put my cam in.

I had installed an EV-23 on 97, FLHRI that ate an inner cam bearing. This 23 was
suggested by a friend, for a bagger. The best way I can explain it, was sort of
like having a another gear between gears, or GOOD low end torque..Tenn.Vol.
