Se 117 redline?
So Im finally having my 17 lrs/se 117 dyno tuned (yes cvaria, you read that right lol Im finally gettin it done!!!) and they asked me what rpm I want to tune it to. Stock redline is 5500, but the screamin eagle 117 kit says it can go up to 6500.
I dont quite trust it to go to 6500 and dont plan on running it passed 5500 but it made me curious as to what rpm everyone else is running their rev limiter to.
Since Im already posting a new thread, on 70 degree days or hotter my engine temps stay at about 280 on the highway (I monitor it with my powervision) if Im in the city and hit a red light, sometimes I have to shut it down so I dont overheat. So for those of you who watch your temps before and after a dyno tune, how much of a difference did your tune make on your temperature? Thanks everyone!!!

It's good that you monitor your oil temps.
The old "rule of thumb" is...your oil life gets cut in half at 300F. And cut in half again for every 10 degrees above that.
There's not much power to be gained from 5500 to 6500 because the intake tract is too narrow to feed the volume of the cylinders. (In essence, your engine is strangling at that rpm.)
And then there's the reliability factor...

they suggested 6200 and I thought it was a good idea so I just had em tune it to 6200 and Ill keep the rev limiter set at 5500.
right, Im just not comfortable running it past stock redline. I know the cams change things, but its still an overhead valve engine. If I get too close to 300, I shut it down. And I change my fluids every 2k cause it only costs about 45 bucks and takes a half hour so its worth it to me to have the piece of mind. Im hoping the dyno cools it down enough cause I really dont want to spend 450 bucks on cooling fans. Especially cause I dont like the way they look on my bike.

Nick,
On my Rig, I have the redline set to 6200 rpms. I do have One Jasons Fan Werks that I can crank on when needed.
I have always shut down my motor if stopped in traffic in the summer heat if I feel it getting too hot.
However with a proper tune, my 117" Ripper runs cooler then my 110" ever did.

Over thinking this. Tuned out to 6200-6500 does not mean you have to ride that far out. And you can self limit with the pv you have.

Well I went from 105/120 hp/tq to 112/121. Was definitely hoping for more of an improvement than that. On top of that they didnt do the flash update to open the acrs on start up so I dont really know what to do about that.
If anyone knows how I can adjust my tune to open my acrs on startup please let me know. Powervision allows you to enable or disable them but it doesnt actually do anything. I listen and feel for the clicks when I turn the ignition switch to run but they never open so Im not really sure where to go from here.
