All I gotta say is AWSOME Mike

Hey Mike got any pics of how the sticks exit the firewall. Would love to see my bigfoot do that, wheels are turning in my head.

That's turning into a cool machine, love it.

Thanks for the comments everyone. I'm working on the exhaust this weekend.

I have a handful of photos of the laterals in my gallery. Here are a few of them:

I have worked on the exhaust some this past weekend and like everything else on this project, I made it more complicated than it had to be. I am using a stock Briggs muffler on the Bandolero motor mainly to help keep the sound levels down since my wife will be driving it most of the time. I shortened the stock pipe coming out of the muffler and then had to use some compound bends to get the pipe routed back up to a point where it could come out in the stock Avenger exhaust location. I was tempted to just make another screen in the side of the engine bay with a relocated hole but this way, I can still use the stock screen. It was time consuming to tack each piece together and get it exiting the screen in the correct location.

I took the stock Avenger exhaust tip and shortened the pipe that it is attached to so that I could keep the stock flare. I then made a somewhat round flare on the new muffler extension to mate up. The only thing left is to weld some attachment points for the springs that will hold the exhaust tip on and then I will clean everything up and paint it.

Lately I've been working on the heat shroud for the exhaust. I want to sandwich the muffler as much as possible in the heat shroud and direct the heat out to the stock Avenger side vent. I started with some cardboard templates and after a lot of trial and error, I finally cut out the metal shroud and began to bend it. I made as many of the side plates into the bottom plate as possible so that I could just bend them into place instead of welding them. I still have three pieces to weld in to complete the sides.

I don't have a brake but I was able to use a couple of pieces of steel and a hammer to get the sides into place. This is the bottom piece:


This is the bottom piece on the right with the top to the left. You flip the top piece over to the right and it will fit onto the bottom piece and completely enclose it:

Real nice!

Not too much going on this week. I had to remove the engine and air duct to test fit the exhaust heat shield. There was a lot of "install, remove, grind, repeat" going on today. Then I painted the heat shield and have it ready to install. The top that I originally created won't work so I plan on getting the bottom/sides installed and remaking the top piece. I just took some photos to keep the thread and my progress creeping forward.

Here is the heat shield painted:


Here it is installed in the engine compartment with the motor:


You can see how well it fits against the motor in this photo:

this thing is awesome! I just read through the entire thread and can't wait to see this on the trails. I assume there will be some awesome videos when it's done?

[prailleraide]

really nice project Mike! That will be a real beast!

Excellent work Mike. This will indeed be a one of a kind. Work looks very professional. As far as a brake some times you got to do with what you have and they look great.

Mike you have done some really nice work there. I think I missed the post where you projected what your top speed was going to be. Can you refresh my memory?

Mike you have done some really nice work there. I think I missed the post where you projected what your top speed was going to be. Can you refresh my memory?

The top speed should be around 28mph with the 26" tires but that's at 5500 RPM. I don't plan on it running there for extended periods of time. Most likely it will run around 20mph in the mid 4000 RPM range when cruising on the trails to the mud holes. That's about what I run with my Max IV.

Here is the spreadsheet I used when calculating my gearing. I ended up with a 19 tooth T20 sprocket and a 21 tooth intermediate shaft so the numbers were slightly different than originally shown here but still about the same final gear ratio. This is geared just a little bit lower than my Max IV.

That is going to be one very wicked Machine. I hope that you have an exhaust system that let's every Quad in the area know that an Argo 8x8 with ASX tires is coming down the trail. I have already seen on several occasions that extra power and the right gearing is very important with big mud tires. It seems that the combination you have will work great as long as you have a clutching system that will keep the engine in the heart of its power band in deep mud.
I have very little doubt that your machine will be king in the mud holes. The smooth bottom and the extra ground clearance provided by the Argo design and the ASX tires should make you unstoppable. I can't wait to see a mud hole competition between you, J.P. Swift and the owner of the blue MaxIV with the Aqua Torque tires. Oh man, that kind out stuff is worth a trip to Busco beach.
