New Talon Pre-filter Snorkel

[DHS_Officer]

After 2 full ride days in Arkansas I noticed no difference in performance. I don't think the normal recreational rider will be able to notice any change. The 3" tube is short and the filter has more open area than a standard engine air filter. If i ever got the chance, I'd like to run the setup on the PPEI dyno for some real numbers. Slowpoke has run the R2C filter for racing with a similar tube setup.

My goal with this product is to provide average UTV owners with something easy to install that solves this Talon air intake problem. Many people have made a homemade version of this but I'm making an "off the shelf" system so that others don't have to figure out how to build this intake. It's a "buy now" solution! Install is simple. Cut a fender hole with provided template, drill 2 new additional holes for cover plate push rivets and slide the one piece tube in place. If anyone ever wanted to go back to stock, I could provide a blank cover plate to close the hole.

When I designed one for my previous SXS (not a Honda) I never got past the prototype stage. I had it on my car and ran it a few times. I finally figured out the problem while out on a ride... you know, the last ride of the weekend. I knew exactly how I was going to fix it....then I rolled my car off a 15 ft cliff and totaled it. End of Project. I replaced it with a Honda.

I think you're doing a great job. I am looking forward to seeing and probably purchasing the final product. Any idea when? And as another stated, if you could pull dyno numbers, that would be awesome. I really like this product.

Well, thank you for that! I'm enjoying doing this.

I have two tubes ready waiting on two sample cover plates to come in from the fab shop. Not sure when those will be ready but the shop is only a few miles from my house. Once I get the cover plates, I can weld them to the tubes. Both of those are slated for local friends to run and test more since I can get input quickly from them. I'm shooting for January availability, if only in limited quantities. I'm working with a US company to bend the tubes for me, but it sounds like they source from China. And I'm communicating directly with China manufacturer for the bent tubes. Sucks, but US manufacturing is not that easy to source. If my local shop had a CNC bender I'd let them do it. They treat me really well! If these sell REALLY well, then I'd look into plastic molding the entire assembly. Plastic is expensive to get started but cheap after the initial investment, which I do not have in my account!

Highpocket check your PM that I sent you

Thank You

First laser cut and cnc aluminum cover plates are ready for pickup. The local shop does fine work!

This is from the PWRTune website regarding the Talon Air Box and air flow. I read this not long after I bought my Talon in Jan. 2020.

Why not a full airbox or intake system? The stock airbox itself if not at all restrictive with a clean air filter. We have tested several configurations of straight to air filter intake stacks, that reduces power. Running with the airbox lid off or vented is no increase in power and the same performance as the sealed stock airbox.

As long as you have a clean air filter the Talon breathes well. My talon intake pre-filter system takes the PWRtune intake tube to the next level by bringing in cleaner air from OUTSIDE the fender and filtering that air. Cleaning the pre-filter is much quicker than opening the air box and changing or cleaning the primary air filter.

My Talon with pre-filter kit using a Desertcraft filter will be on the PPEI dyno tomorrow morning! I'm anxious to see what happens.

Very cool!

I’d be interested in one when they become available. X-4 live valve.

Dyno run completed. No loss compared to stock, maybe even a very minuscule gain. I’ll have to print charts later. I’m happy with no loss though.

Awesome!

Another discovery was that my talon made 3 more hp than any other stock talon they tested. My opinion is the amsoil engine oil. That’s the only difference of my machine. They said Honda oil was in all the other stock talons.

Want to share what it made for HP and what you have for modifications?

 

[highpocket74]

Edited:
91 HP at rear wheels, 87 octane, Stock air filter.
No mods other than amsoil engine oil.

 

[SLOWPOKE693]

91hp to the wheels is a very respectable number for a bone stock naturally aspirated UTV engine.


Gaining 3 wheel horsepower by using a different engine oil is HUGE.

Looks like I might be switching to Amsoil. Thanks for the report.

Oil will not give you ~3% gain in power.

SAE calls for correction factors to mimic 60 degrees, minimal humidity at sea level and these correction factors are just a good guess at best and comparing dyno pulls taken on different days is somewhat meaningless because the correction factors are not very accurate. Unless these dyno comparisons were done at near the same air temp, humidity and barometric pressures. you are comparing apples to oranges, even with correction factors. There is no way to get the correction factors spot on but when the runs are similar (like within hours of each other under similar weather conditions), you can be fairly close. On dyno runs that are weeks or months apart, the best than can be hoped for is 2 or 3% accuracy. There is your 3HP difference right there. Have them run all the machines on the same day at the heat of the day and see what happens. I am pretty certain you will see the machines are all about equal.

For example, my stock LS motor at 4500 feet reads 328 RWHP (corrected) on a 90 degree summer day and 335 RWHP (corrected) on a 31 degree day in the winter. That is about a 2% difference. The correction factors are nothing more than a good guess.

Another factor is age. A more (and properly) broken in motor can create more power than a newer (or severely worn out) motor. Were they testing new machines and yours has several thousand miles?

There are just too many other factors to say your oil is giving you 3 HP. Only way to tell is make 3 runs with Dino oil, change and within an hour of the first runs make 3 runs with Amsoil. The outcome will surprise you.

Nobody ever said it was definitely because of the oil, it's just a theory @highpocket74 came up with based on the fact that oil was the only difference between the tested machines.

I'll also venture to guess that PPEI has dyno tested multiple stock Talons on many different air quality/temp days to come up with that 88hp average and isn't just talking out of their ass like you want to believe. Keep an eye on their FB page, they plan on dropping a whole bunch of SxS performance tunes and products by the end of the year, including stuff for the Talon. These guys are serious about performance and I'm willing to bet that the products they put out are going to be at the top of the game. PPEI doesn't fawk around.

 

[highpocket74]

There are a lot of factors in the dyno runs. These guys make many dyno runs so they know what they normally see. We are at about 30 ft above sea level down here and except for cold fronts almost tropical! Temperature down here this morning was almost 80 degrees. I'm simply saying that the dyno tuning guy was very surprised to see 91 hp out of a stock talon. He made 15 pulls with my intake system, pointing out that it took 10 pulls to get the oil temp up with increasing hp, the last 5 pulls basically all the same hp. Then we switched intake back to the stock stack and he made about another 5 pulls, with almost identical hp numbers as my intake.
The big point to remember is that there is no loss of horsepower with a pre-filter.

 

[highpocket74]

Here is the dyno comparison.
Red is with pre-filter tube and Desertcraft filter, the R2C would be very similar if not the same.
Blue is with the stock intake stack.

That's great news. And I assume you have felt no difference in throttle response?
No dang it, if you can just get that thing made in America.....

No discernible difference in throttle.

I’m trying to work with American companies but sometimes they don’t even return emails.
