1st line is final tune torque
2nd line is 1st run torque
3rd line is final tune hp
4th line is 1st run hp
dyno chart is SAE
Not happy with with #'s but I'm OK with them. I suspect the dyno tech at my HD shop is not that experienced, all new faces there. My dyno tune was part of the deal when I bought my bike in March so it had to be done there. I called Doc and wanted to have him tune it but he won't touch a SE Pro Tuner. Rideabilty has improved, definitely can tell the difference in performance and I'm waiting to see if gas mileage is good.
Happy would be 100hp/100tq. Only got a 4hp increase from cam install. I'm probably losing some tq because of my pipes but I've had Thunderheaders the past 15 yrs and I wanted something different on this bike, something purty.
Ah, now that I'm on the Mac I can make out the final torque curve much better, and the first one wasn't even visible on my other crappy monitor. Yeah, seems like you'd expect a little more than a 4 hp bump after all of that. Hope that mpg is better, but then again them V&H pipes are purty!
I have a 2011 RGC/103 with the upgrades listed below, installed... Here is the paper for my tune after the install. It had been running on a canned map for a couple of months or so and although it was running sooo much better than stock, with a tune there could be better performance. Here's the result of dyno tune from HDHD
SE Ventilator AC
V&H Power Duals
V&H High Output Slipons
I'm no expert either but I do read and research the forums and hang out at some of the dyno tuners whenever I'm in Daytona. Also had a short conversation w/ Doc before I had cams installed and dyno'd.
I figure good pipes are good for ~5hp so that leaves me still missing ~5hp. I think a 103" motor w/ cams, breather, pipes and dyno tune should be low to mid 90's for hp and +100 for tq. I have no idea if or what the HD techs did as far as the dyno tune. A dyno tune can take 4-6 hrs to perform to get it right and produce a custom map. I doubt that much time and effort was put forth on my bike. As far as gas mileage I'm at 1/2 tank showing 100 miles on trip meter. That ain't good but I'll wait to pass judgement on that when I refill the tank. I still have a little throttle lag that I don't like but this is my 1st TBW bike. That being said there isn't much I can do at this point except mull it over and get some of your opinions and comments. Thx.
Also, there is a difference in STD vs SAE dyno charts as some of you probably know.
They actually do it is just that the scaling is different. Look at the left side compared to the right side. If the scale were set the same they would cross where they should. Having the scaling set diff does not change the numbers and it is fairly common.
I just picked up my bike yesterday from Geoff at Cycledoctor in Costa Mesa, Ca. I had him and Steve (mechanic) install parts and tune the bike. I can’t say enough good things about the entire process dealing with Geoff. He got me in and out before the Holiday wknd and trip to Shark Week X next...
This is the build info on my 103" to 107" twin cam. The following is my parts list. I picked all the parts and did all my own assembly. Not my first build.
MChalmers Enterprise Inc.(Matt Chalmers) in Texas worked my heads, 1.85 intake valves 1.6 exhaust valves, 1.71 intake ports. CSR 58mm...
Finally retuned my 08 w/SS124 LC engine.
Last year it pulled 124/138. This spring I sent my heads in to George at Star racing, and changed my FatCat out for a Boarzilla. Was able to make 148/143. Can’t doubt that head work works
It’s taken 3 years to redo the drive train from output shaft to...
Jim Libonati at Mega-Flo did all the machine work and porting. 124", 11.3:1, S&S Superstocks, HPI 62mm cable tb, 6.8 inj, 662-2 cams (not ps or ps 2), dragula 1 pipe with 3" baffle, AIM vpc and Evo Basket. 3.04 final gearing and a 180 rear tire.
