If I spend this $1400 to $2000 What will my FJR gain?
The respect of other board members who are still trying to justify their similar expenditures. :rofl:
amen,brother
It seems from all the dyno test I've read the slip ons are worth about 3-4 horses regardless of who's they are and I haven't seen any A-B dyno test on the Power Commander stuff and all I got from the fella on the phone at Dyno Jet was all about the different number of maps available. I asked the guy at Dyno Jet the direct question, will the PC-V increase the HP on my stock 08 Fjr and he said, " if your fuel curve is correct now it won't, if it isn't it will". I asked him what the stock AF ratio was on any stock FJR and he could not answer me. The FJR has been around for 7 years now and so if they are selling a product that cost $400.00 they should have a dyno test on it because they have test on the jet kits for FJ1100-1200 Yamahas and those kits only cost a hundred bucks.
I got a dyno test from 2 Brothers comparing their M-5 carbon fiber canister to the stock set up and it made 130.5 horses vs 127 for the stock set up but the graph doesn't show the air fuel ratio which means a lot when comparing these test.
Another issue that I haven't seen addressed is the ignition timing which is very important and I believe there is a seperate module that can be wired into the PC III and V that allows altering the stock curve but Dyno Jet has no data on what the stock curve is nor is it listed anywhere that I know of other than the shop manual list it at 5 degrees at 1000-1100 rpm (idle). Dale Walker says he will give you his map if you buy his pipes or slip ons but he has no dyno test to judge it's effectiveness so who knows.
I'm still pondering what to do to my recently purchased 08 but it looks like my only real choice is to base line it on the dyno and then start throwing parts at it until something sticks because all I've heard is maps, maps, maps, how loud it sounds and how much smoother it got after installation the Commander which is all meaningless without a dyno test and an actual test of the AF ratio which Walker or any of the pipe binders have listed and probably for good reason.
I would think removing the cats would help a lot however Muzzys complete system with no cats only made 128 horses vs 121 stock on an A-B test but again he didn't use the PC for the test nor did he list the sniffed AF ratio so who knows. Dale makes a complete system but he doesn't have a dyno test on it but list only the test for his slip ons which sounds dubious at best.
The problem with the FJR if it has one is that the camshafts are extremly small for the size of motor it has. At .040 checking lift my cams only have 225-225 degrees of duration on both the intake and exhaust which is pathetic for performance but good for low emissions and 2500-3000 rpm grunt. I called WEB cams yesterday and they said I was the first person who had ever made an inquiry about cams for an FJR which I found startling but to make a long story short I'll be sending them a set of new cams which they will profile after which they will be hard welded and custom machined/ground to a profile of my choosing.
With a stock motor all this Power Commander and slip on muffler stuff is just bull shit as it only nets about 3-5 hp with the stock air box and you can have all the maps in the world and that's all you will get except more noise.
