I was sad when I seen the HP results. I had another run but my bike was @ 229 degrees, so I passed it up...lol. I'm thinking about a power commander, but is the $300 worth the results? What do ya guys think? Suggestions? Thanks.

 

I dont think there is a ton of HP gain with the PC. It is mainly for a better tune. Be lucky to get 2 or 3 out of it if thats what you are looking for.

 

I was also running 113 octane which I think also hurt me in the HP numbers. I will run Shell-93 from now on. I also noticed a huge doggyness when I dumped the clutch, I went from 11k rpm to 1500 rpm when I took off on the dyno, I prolly should of slipped the clutch a lil more, but still, I think a PC will help that a bit. thanks for the input!

 

Doesnt honda only rate these things at 110 hp? Why are you so dissapointed with your results?

 

It's a 600cc bike. You are not going to get huge gains out of that much you do to it. With a full exhaust, pcm, and some tuning you might pick up 6 or 7 hp max. Bikes now days are so finely tuned it's hard to get good gains without tearing into the motor or adding forced induction of some kind.

 

so a friend of mine has an 04 600RR....how much faster would he be in the quarter mile than the F4i? he has a power commander, full exhaust. just curious mostly..thanks.

 

I dunno, I would have like to see better than stock or stock, numbers with a K&N + Exhaust... but I <3 the bike anyway :P

 

Slipping the clutch would've netted better #'s but is hell on a clutch. I'm wondering about your shift points -- RT's are erratic but somehow you managed to make the best ET with the .922 -- almost 1/2 sec slower than the 1st run but best speed, ET and HP. Go figger?

 

RT in no way figures into your ET...you could sit for an hour when the light turns green...and then launch and pull a good ET.

ET starts when RT ends.

 

You are correct -- I don't know what the heck I was thinking.
