I haven't re-dyno'ed the RT 2 yet, but based on the numbers from both the RT 1 and 3, I suspect it shows similar gains. Apparently my ecm learns slow. At any rate, I thought I'd share today's dyno chart from the RT Type 1 (the original) and show the comparison to stock. No, I really didn't expect what I got, but I'm pretty happy with it.
On to the fun part, charts.
Yep, it shows 18, possibly 19 hp for a gain between 8-9k rpm.
Real good numbers Dean, looks like you got these with the stock ECM also, due to the average A/F ratios, and thats great. No real need for tuning. Maybe someone will use one of your systems and go with the race ECM or other tuning though and see even better numbers. Good job my friend. Bob
It's about 9.5" long and it's not as loud as a Jardine, but it's a much deeper tone. Yes, I've heard one (had one for 4000 miles or so) and it's totally different for the sound. The Jardine is a much sharper note, it's like a gunshot going off when it starts, then it's almost like a machine gun firing away. I'll look into putting the prototype back on and getting some better video.
that clip when clicked on says "This is a private video. If you have been sent this video, please make sure you accept the sender's friend request." What up with that? Do you need a youtube account to view it?
Glad I got to meet you today! Guys I got to hear and see this bike today on the dyno and for about 30 miles of riding. Amazing! Looks like a well built quality product! Sounds great and the numbers speak for themselves.
Now I just need to buy an 1125 to add to the S2 and the Uly
Ross, I had a very good time today, thanks for all the commentary, it made the wait go by so much faster. I wish the day had been longer and that I would have been able to stay for the dyno run/shootout at Quicktime. The food sure smelled good there too. Pm me if you want to drop that Uly pipe off, I'll play around with it some.
I have a K&N filter and a bone stock ecm that has not been touched yet. The K&N has been on since the 2nd week I've had the bike and I'm at almost 14k now. It runs lean to some, but as of right now, I'm fine with it, especially the numbers it's putting to the ground. I also manage to average 40 mpg commuting on it.
Froggy, your mileage will drop some. You will not be able to resist twisting the throttle. Just don't get any tickets, I came kinda close today. Ross and I rolled by a pair shooting radar at us right after I had hit a rather ludicrous speed maybe 30 seconds before. I am fairly certain they heard me but didn't see it and they most definitely didn't get me on radar. We rolled by them doing 62 in a 60.
Remove the stock pipe, 5 bolts total, 2 clamps. Remove the right oil cooler bolt. Remove the left oil cooler bracket/bolts/nut. Remove both bolts in the rear. Loosen both clamps. Loosen the right side rider peg bracket, 2 bolts, do not remove it though. Stock pipe will almost fall out on it's own when you loosen the bracket on the right side.
Reinstall the front left oil cooler bracket and bolt. Obtain an extra nut for the right side cooler bolt, I use/ship 3 nylock nuts with every exhaust, as well as longer bolts for the rear mount.
Installing it is pretty easy once the cooler is bolted back on. Only 2 more bolts at the rear and 3 clamps. Just a little bit of RTV silicone inside the pipe to seal against pipe imperfections, tap the collector up to seat it, clamp it, then put the muffler on. Sometimes assembling the unit will help, it just depends on the angle of the muffler that you order.
Me? 5-7 minutes to install or remove the stock pipe. I'd recommend removal of it for the first oil change to get to the right side screen/trap. 5 or 6 torx bolts on the right side of the engine, take it off, clean the screen. I take it off for every oil change, just to make sure there's nothing in it. I can get to it with any style aftermarket pipe, the stock pipe must be removed to get at it.
D_adams, You should ship me one slip-on for free, Then I will make for free a fuelmap for you, and people can buy them and install it online here www.fuelsolutions.nl
Dean, your RT-3 looks really good. Gaining that much horsepower is pretty impressive too. If you'd had the RT-3 available before I bought a Barker, I think I would have gone with that instead.
Can you explain the dyno charts? What are the variables for each run? I assume one is stock and the other ones are from your pipes, but which is which?
It's all pretty much in chronological order on the dyno charts page. Stock, RT1, RT2 and RT3 with a followup of the RT1 to validate something I had suspected after the 2nd week. I had the design right, I just didn't allow the ECM enough time to learn. AFV is at 105/100. It was 100/100 on the 1st and 2nd runs. Sorry things didn't work out for you buying mine, but it's all good. You're happy with what you have, I'm happy just making a few of these at a time.
Stock, RT1 original run, RT2. Later post shows the RT3 after I ran it for a week and posted the gains. After I saw that, then I decided it would be worth the $30 to find out if the RT1 posted the same gains. It did. On average, the temps were around 55 degrees. I don't know the baro pressure, but they were all done in Jan/Feb/Mar. You guys have seen the slow saga build along, I was as suprised as anyone to see such a huge gain, even though that's what I designed it for. Industry standard says use a 2" midpipe and I disagree, for obvious reasons. I don't know what the Barker pipe dimensions are, but I'll bet money on it ending up somewhere around a 2.5" OD near the muffler and it's possibly got a reversion cone in the end of the taper. It's the old school way of building a pipe, which I like, but I haven't heard one in person, so I won't comment on what it sounds like. Videos never do them justice, that was why I bought a Jardine originally. I thought it would sound better in person than it did.
I just realized that the comparison run for "stock" was actually one of the original RT2 runs, it's different by .1 HP total and the torque is off by .12 ft/lbs. I do not know how this happened, however, the run was nearly identical to stock, so I'll leave it as is. I don't have the editing capabilities anyway. I need to find out where the original stock run file is now, I assume its at the other dealer. They shared the same dyno for years, it's in a trailer. I guess they have their own computers for doing these, I assumed it was the same one.
I apologize for the mixup on the chart, but the gains still stand.
