Modified horsepower #'s from 525???

[Eddie11gt]

Has anybody modified their 525 to a 540 or just done cam/port work and what horse power did you guys dyno or think your putting out? I’m just looking to see what direction would get me the most hp for my $$. Please submit Hp #'s.

numbers really dont madder unless you want bragging rights or something, and If you have a outlaw 450/525 call ct and they will tell you the way to go!!! and if you really wanna know i have a ct pipe, stage 2 cam, K&N filter, 5 angle radious valve job, ported head and jet kit and Im pushing high 50's low 60's

I have a 2007 525 IRS. Initialy I had the JD jet kit, HMF slip on, K&N filter and was not happy with the result. I was looking for more top end and top end grunt. I bought a vortex cdi and did not get any magic. Dyno'ed at 47 HP Rear wheels.
I fitted a 540 Kit, got the head flowed and ported and fitted a custom Yoshi full system + SXS 540 cam. I have had such good results that I have set the Vortex back to standard setting. I have not had time to re dyno but I really have not felt the need as my results have been just what I wanted.
