New concept High Flow intake for 111 bikes

Thunder Works is introducing a new intake for the 111 bikes. (A model for the 116 bikes coming soon.) This is a very high flow intake that employs a specially shaped airbox to induce a smooth efficient air flow. It uses a large cone filter and comes with a rain shield. Not a sock but a solid roof over the cone so it does not impede air flow. Since it requires eliminating the stock air filter set up, you now will be able to suck all of the cold air your engine wants. Some new concepts are being used here. Since air slows down when it is forced to make a turn, this airbox eliminates nearly all of that inefficiency. It is priced affordably. Compare it to other filters and hopefully you will decide to pay less for a better filter. LINK: http://www.indianaftermarket.com/ripper-intake-blk.html

Show me the flow bench data. Stock intake vs yours vs other claimed high flow intakes. Data preferably taken from the same flow bench, by the same operator, under the same conditions. Here's a flow bench for sale on Facebook. It's not too far from me. If you're interested I'll even offer to go check it out in person, broker the deal and make sure it gets packed and shipped to you safely as it's not too far from me.

BTW, that "roof" as you call it looks like it might provide a little protection from rain as long as the bike is just setting still, but once moving at any speed it will be totally ineffective in heavy rain. It looks like it would work pretty well to catch bugs and build up a pile of them on top of the filter though.

Interesting I’ve been looking at a plenum style intake, can’t find any before and after comparison number with good empirical evidence. Any dyno data with before and after HP and torque results? Tune data showing increased volumetric efficiency?

WTF did you just say? English man... I'm guessing you are a fan of Star Wars movies.

I Ordered one "Evel Imperical Super Air Ripper today"

Nope don't


LOL, not a Star Wars Fan at all, worked in engineering jobs since 1991 in various forms and that word is quite common terminology.

Wow, excuuuuse me for introducing new products for the Indian bikes. Here we go. First of all large air filters flow more air than small ones. Da (There are some differences with mesh size but most filters are very similar in mesh size.) The next item of concern is the flow path. Air flows like a fluid and is subject to the same hydraulic principals. Making the air turn a hard 90 degree corner slows the flow down. So a gentle turn is better. An airbox that is round and smooth as apposed to square eliminates much of this flow problem. An airbox also serves as a buffer for extra air. Air flow ratings could be helpful if the comparison from one brand to another was honest. Measuring air flow is complicated and the numbers don't mean that much. I looked into buying or building an air flow bench meter. As I researched I found that K&N doesn't even offer ratings on their filters anymore. So I am not going to offer numbers that mislead people. This filter is very non-restrictive due to its size and the flow path is excellent. If you don't believe it, don't buy it. Whizzy, how many air intakes have you designed, tested, manufactured, and sold?

Now the rain shield. I sell and ride with totally exposed cone filters. They don't absorb the rain coming down or splashing up or blowing at it. I have check my filter after being caught in down pours and no water was inside. The rain guard looks cool and between the gas tank and the guard it prevents water from hitting the filter. When riding not that much splashes up. the fenders on the Indians contain most of the road water.

I don't have any dyno reports since this is a new product. A dyno report also takes into account many other modifications. Just adding a high flow air filter does not make your bike more powerful. If you put more air in an engine it needs to get out faster also. Thus a high flow exhaust is needed. Then you will also need more fuel to match the increase in oxygen. Thus a fuel computer of some sort is needed. This high flow intake is just one element in building a more powerful engine.

I am constantly experimenting and designing new products for these bikes. I have over 80 products that I have designed, tested and sold. Not everything I do is great but I am out there trying and making new stuff all of the time. I don't appreciate being trashed every time I come out with something new. I know what I am doing. My approach is often unorthodox but that is how I roll. My 111 Springfield has beaten 116 bikes. I build stuff and try it out before I offer it for sale.

You are welcome to dislike my designs. You are welcome to ask questions. You are welcome to not buy my stuff. But if you want to talk to me with disrespect, I am going to fight back. This forum should be used to help each other. That is how I approach it. Consequently I also sell lots of merchandise. If you find something better than mine, then go buy it. Meanwhile if I see something better, then I am challenged to step up my game. You all need to act more respectful of each other. No one here including myself is such an expert that we should bow down to them.

geez... 5 posts in and the keyboard commandos are out in full force.


How it was done....before the pussification of America

as an example
You have a Hot Rod
You want more performance out of your Hot Rod
Buy some parts...Bolt them on
Seat of the pants dyno run around the block
Better ? Drink a beer or two with your friends.
Talk some junk..
Worse ? Drink 4 beers with your friends..
Un-bolt and remove new parts and start over..

Shit is simple...get off your computer and go for a ride...

Nice looking product Marcus, injection mold or 3D printing?

This is 3D printed. I have been working on this for about 4 months. I had to overcome a lot of issues. I can't find anyone else doing this. I understand why. It aint easy. I use a modified ABS. It can withstand 300 degree temps and full exposure to gas and oil. It is basically the same as all that black plastic under the hood of your car. The 3D printing allows me to explore shapes that would normally cost a fortune to make. This is not like the normal 3D printed stuff you see. This is tough and durable.

I don’t disagree with your points - but thread is from a vendor - who posted about a new product When in the business of selling goods - you should not get offended because you are asked about your product specifications or performance or even how the questions are asked. Again I complement Markus for developing new products - and I would love to hear why his product over the completion.

I believe that without change and people willing to explore new ideas we would never advance in this world.Some times we may get things wrong or need to adjust our inventions/ changes such as modifications, but at lease you need to start some place.with constructive criticism we can make positive or negative change. But having the foresight to do something is better than nothing at all. I take my hat off to Marcus trying something new. If it works we all benefit and if not well guess who looses then. But give the guy credit for attempting something new. I am sure if this is his first attempt he won't sit on his hands and except it as being the bees knees till he gets it to where he and the market wants it too be. I am not knocking anyone who has a go so all I can say is thanks for at least trying to do something that gives us all a choice .
Sorry what would I know I am just a Kangaroo that lives upside down compared to the top end of the world lol.

I like the concept of the air box instead of an elbow. Looks to be well thought out. I would have to agree that without flow numbers to back it up it's still theory. I wish you had a picture with out the rain guard so I could compare, cause I think the cone filter would look bad ass uncovered. Keep plugging away Marcus.
 
#23 ·
Is the rain guard removable? If so, what does it look like without it installed? My personal opinion is that the ‘look’ of the intake detracts from the classic styling of the Indian design cues. I prefer style over performance, but I also understand many riders may differ in opinion on that. Kudos for sticking it out there.
 
#24 ·
How far does the air box portion stick out ( knee room) compared to a stock air box? How hard is it to mod the program to print a "clean looking version" with out the rain guard and mounting ribs? I have road in the rain with a open element air cleaner and am not concerned about it. You could offer two versions. As I look at my bike more than I ride in the rain, I am more interested in flow and looks as opposed to flow and rain.

If we all gave our feed back on our thoughts and why we like or dislike something about a design then thats great as long as we respect the fact that someone is trying to do something too assist all of us to have an option other then over priced Polaris products. By making construction comments, good bad or suggestion on what you think may improve the product or design has to be a big plus for all of us in the end.

It is very interesting how much controversy this brings. I care about your opinions of course. But I design stuff that I like and think is good. I have been doing this in different field for about 55 years now. People buy my stuff and like it. So at least some people like it. I don't expect everyone to like it. Today I am going to ride with this new filter on my Springfield. Probably get caught in a short thunder storm. I will post some pictures later today showing the position of the unit. Knee room was a concern while designing this thing. I had to change it several times. I might even make a video showing a garden hose spraying the unit and then how dry it is inside. Just an idea. Yes the rain guard is held on with 4 screws. So I will show it without. Thanks for all the love. And thanks to WhizzbangK.C. for we are now talking civil. I will admit that I am not normal. I started designing stuff at 4 years old. I got some 2x4's from the lumber yard and built a rabbit trap. It worked but the rabbits did not cooperate. It was the beginning. I have designed hundreds of items over the years. I design them to my tastes. Enough people like them to keep my bills paid. Ride safe. My bike has been getting dusty. I am out of here.

Here are some more photos. Some show without the rain guard. I think I will make a version without the guard and sell it cheaper. The other photos show it looking straight down. You can see that it is mostly under the gas tank and it does not impose on knee room. You can touch it with your leg if you press against the tank, otherwise it does not touch you while riding.

It was an honest up front question and comments. I even offered to help him with procuring a flow bench and it was a serious offer. Any attack read into it was supplied by your frame of mind when reading it and was not intended by me. I usually don't have any reason to attack anyone, and won't unless provoked. But... I'm not in the habit of editing my thought or speech in a futile attempt to avoid hurting feelings, as all that does is muddy the point. Trust me, if I'm attacking anyone there will be very little question about it.

BTW, while all the sensitive types have been gnashing teeth over this, Marcus and I have had a quite civil discussion on IM. Just so ya'll know. :cool:
So do you think @Marcus has a winner. Maybe just needs to be dialed in.

I like it. I can work with that black plastic cover. Maybe paint it red, like my bike.
Much respect for you and @Whizzbang.
Gonna check your site, see what see goes for. Ride Safe.

I am not able to find air flow numbers for any of the filters out there including K&N. Maybe you can help me by showing where to find these numbers so I can sell my plastic junk. And by the way I don't use a drawing board. I use a Mac 27" with professional CAD software to design with.

I might be the only one here that notices vendors hawking their products in the general discussion section when there is a separate vendor section for that very purpose.
Vendors can and do post their products anywhere in the forum. In the vendor section they are able to moderate the threads (edit and remove others' posts) but some are more interested in the exposure the general forum has and as such are limited in what they can do with posts. Their prerogative for becoming supporting (paying) vendors.
 
#35 ·
Meggie, I for one have to say thanks for your support you show this forum along with the help you offer too the members. If it was not for supporting Vendors the forum would not be as good as it is. So thanks from me and I am sure a lot of others here would say the same.
