I went and paid a visit to Tim yesterday at SDR Motorsports.

I told him I was interested in a simple lightweight front bumper for the Dunes. We dont need much out there and light weight always helps. No Winch!! He told me he would have pics of his Sand Bumper out Saturday.

I also asked him about an Oil Cooler Kit and referenced a few that have already popped-up. He told me he would have one very soon with complete brackets for mounting and one added feature that the others so far dont have, which would be a Remote Oil Filter. He pointed out a Teryx he had on the floor and showed me the Oil cooler and filter that you could just reach in and grab for easy removal. No removing floorboards, fenders, engine covers etc. Now that appeals to me.

What really excites me is that SDR has been in league with Ron Wood racing to develope a new Dual Exhaust for the Commander that doesnt require removing the lower Bed. Ive patronized Ron Wood for years. You can get the details on the Exhaust by clicking on the URL. They do top shelf stuff imho.

Ron Wood Racing

:devil:

This can all be considered Hearsay as I am not Tim. Im just relating my experience.

Nice, Ron Wood does have a top notch exhaust, I know several people who swear by them!

I've been considering an oil cooler on my Teryx, guess I need to give Tim a shout.

I just got off the phone with Elliot over at Ron Wood Racing. He invited me over to check out the new dual-exhaust this Monday. He says its a Monster. They will have some kind of controller for tuning available as well. They are doing the testing this comming week. I did verify that this exhaust does not require the removal of the Lower Bed on the Commander. So I can have my cake and eat it too!

 

[dieselpowered]

Well when it comes to Rotax and exhaust, they do an excellent job, so I will be interested in seeing some numbers when all is said and done!

I have heard nothing but GOOD about Ron Woods exhaust, my only question is where we ride in Oregon our Db level is 93,:furious: I'm curious what their Db would be......Barbara

Ron Woods is extremely high quality materials and workmanship, but also known for the LOUDNESS levels....not compatable with our ODNRA.......Lance

 

[dieselpowered]

Oh are their DB levels pretty high? I am not sure what the DB levels are, however, they are supposed to be either joining us or sending me the specs on their exhaust. Nonetheless, I will see about getting a DB reading.

 

[Razorback Dave]

Yes, they are mostly no compromise for performance, but they also have the Quiet Core option, which is what I will get. Its a Spark Arrested Quiet option with no loss in power so they say. Its the pair of Cones in the middle of the pic. Spark Arrested and Quiet should be somewehre around 92 decibles, but I will ask for sure on Monday.

Thanks Dave for looking into Db's LbR & I do sound checks and from previous experiences they were over our 93, more like 100 &101, it's nice to know that they have the quiet cores available.....

Hey, that is GREAT news that they now have a quieter option.....years past, the RW name was synonomis with many loud Glamis machines.....USE to be a bragging highlight with some pumped up Rhinos......Lance

 

[Razorback Dave]

I paid a visit to Ron Wood Racing yesterday. As usual, Ron wasnt there. But, Elliott was, along with the Crew. They were actually working on the Commander. Just finishing up the mounting of the OEM replacement exhaust.
No Vids or Sound Bytes but that will come.

Elliott told me the Spark Arrestor option on the Duals is very quiet.
Perhaps we will get a Vid and Sound Byte when they do the Dyno Tuning this week.
Oh, pricing on the Duals will be $932. Sales are approx 3 weeks away, not before T-day.

 

[dieselpowered]

Really nice looking system indeed! Is it me, or do that cannisters almost look like they could be hit by the axle under full compression?

Looks to me like it is going to be a great system, can't wait to hear how it sounds and see some dyno numbers from it.

 

[Razorback Dave]

I thought about that too Mike. All I can say is, I would think they,took that into consideration. Also, from the camera angle, you dont really see the actual clearance afforded. I am thinking now, that is the reason they have the spring off the shock in the pick. So they can articulate the suspension to its fullest reach.

 

[dieselpowered]

Yeah, and that is what I am kinda thinking Dave, it could just be the camera angle playing tricks.

 

[LBR]

My inquiring mind wants to know:::

Could you tell how tuned/equal-length the two headpipes are?

Is it a 2 into 1 into 2 system with an "X" pipe or 2 completely separate pipes/mufflers with or without an equalizer pipe?

Does each headpipe have it's own bung for O2 sensor?

Thanx!.........Lance

 

[dieselpowered]

Looking at it, it does appear that the headpipes are of equal length. I do not see a X pipe, however, that does not mean one does not exist. I am inclined to say they are two separate headpipes back to two separate cannisters.

 

[Razorback Dave]

@dieselpowered
You are correct. Two seperate pipes. No crossover.
@Lance
Yes one headpipe is longer than the other but not by much. They tried to keep it all as equal as possible.

I doubt they would put anything out that isnt up to reputation standards.

The reason I like these guys is because they are right in my backyard here in Orange County. Like a 15 min car ride. If there are any problems I can just walk into the shop.

Thanx Dave....just wondered how close those head pipes were to equal length and if they were joined together anywhere not pictured......

I am planning on our exaust and electronics install starting next Monday....will take a controlled environment before and after sound-byte video and post up to all for comparisons....Lance

Here is an email I sent and the reply.
Subject: Commander Dual Exhaust Pics

Elliott Hi,

Your pics were a hit. I posted on a couple forums. Muzzy's even chimed in on one.
Im getting a few questions that you might be interested to answer.
Is there a bunghole for sensors?
Why no crossover (X-pipe)?
Muzzy's indicated that they had some issues with the pipe position as the Woods Pipe. Is there any problem with Axle Shaft clearance and the Pipes?
I noticed you had one spring removed from the shock. Was this to facilitate articulation of the suspension for clearance?

One last question for now. While doing the dynotuning to develope a chip for the commander, is it possible to use the chip to disable the speed restriction thats on it? I believe its 75 mph. Another vendor was talking about it for the Outlanders and Renegades. If anyone knows Rotax its you guys.

Also, I just met a guy on the forums from east Texas. He is Team Racing with a Commander already. His Motor has been brought up to 1200cc's along with all the other go fast mods an engine builder does. I know its very early, but has Ron Wood Racing thought about going this way with the Commander Motor? Some outfit in Ohio called AFTER MIDNIGHT RACING

Any reply will be gratefully appreciated and passed on thru the forums.

Hello Dave,

Did you get my call regarding a system? We can have one ready next week.

No bung for O2 sensor.

Crossover pipes are more for meeting emission standards. Never saw a race pipe with a crossover.

While fitting the pipe, we removed the shock spring and used a ratched tie down to compress the bottoming rubber on the stock shock. With that, there is still plenty of clearance for the axle.

As far as the speed limiter, Can-Am is still trying to find a way to override it for their race teams.

We will be working with Zakowski Motorsports in the GNCC series, so who knows where it will lead? According to them, the only real difference in the engine is the crank stroke and rod length, so all of our 800 hop-up parts should work with the 1000. We have had pistons made in stock 91mm bore, 93mm, 96mm, and 100mm. 91& 93 are in stock.

Elliott

Thanx for taking the time for that email Dave......

So you'll need to weld in a bung for any open or closed loop system using an O2 sensor then......could I suggest to have RW install at least 1 bung for you and "put it on your tab" as an option.....make sure they install it on the leanest-running cylinder of the Rotax (I can't remember which one it is right now!)....we haven't un-packed our Muzzys yet, but am told there is a bung in each headpipe (for independent cylinder tuning) as their website shows....some serious Rotaxers will create a map for each cylinder, one at a time, then merge the 2 maps for a third map to run....

And then this is a full-on RPM race system.....an X pipe/crossover pipe does a couple of things I'm really needing on ours....it balances out the individual cylinder impulses to:

1) amplify lower-end torque of a NON "all-out-balls-to-the-wall-unadulterated" race engine...more like a high HP street machine engine used for anything less than race-day only
2) quiets the exaust down by merging the pulses

It is definately handy to have them located in your backyard for any future support too!............Muzzys is in our backyard too, but we have a HUGE backyard to :running: in....5 hours worth to Bend, Or......Lance
