I keep reading threads on cams, a lot of people said that the 255s were great for the money, but not in an 09'. Why is this? What is there a difference between 08 and 09?

Thanks...

 

Mine works just fine. I've never heard of what you are saying. Must be an old wives tale.

 

I have no idea if there is something different between 8's and 9's. I put 'em in my 10 and it runs about the same as my 8 did with the same setup...in fact..they seem to be better and I didn't have to do a tuner this time. I think it is because the maps (for the 10's anyway) are a bit richer due to the cat in the headers.

 

It is, they work just fine!

 

Did the gearing change happen in '09 or '10? Maybe that's what they are talking about. Better low end gearing allows the use of a more mid-range cam. 255's bring on the torque real early compared to other cams and that is nice if your low gear is tall like in the '07 and '08 models. Nothing wrong with the 255 if it fits your riding style.

 

SWEET! I was hoping I didn't buy the cams for nothing.. Thanks. Now to get them installed.

 

I believe there is a minor change in the gear ratio between the 08 and 09 models. I have a 2008 Ultra and did a 103 with 255’s. I love them and feel that they perform well in the rpm range that I ride. My peak torque is at 3900 rpms while I do not normally ride fast, I am running about 3200 rpms at 90 mph. Unless you are looking for more torque at higher rpms, I think you will be pleased with them.

 

I run them in my 09. I really like them, power where I ride, not where I dont need it. Now that they are getting installed, lets hear what you think....
