Loaded her up and took her to Racin Station for open heart surgery!!
Any Evo Vipers out there??
- Thread starter Prairie Dog
- Start date
If I understand it correctly there were only a few dozen units shipped out last year. Most of those went out to serious users who rode the sleds hard and reported back lots of info to EVOPs.
This year the package should be much more mainstream, and see a lot more use!
This is a very high end package aimed at a highly skilled rider who wants MAX performance out of his Genesis engine AND is intended to be installed by a trained professional. I installed my supercharger, I installed my Turbo, I had a hard time installing this turbo and needed significant help. The manual is good, BUT it is written to be read by a mechanic that can easily read between the lines and see obvious steps that are not included!
All that said.
I did talk with other EVOPs users last winter and they were singing the praises of this kit. I had PRECIOUS LITTLE TIME on it myself as our season was a total blow-out here in South Eastern Idaho and the trip to Canada was nothing but ICE. I hope to be able to start offering SERIOUS commentary on how it performs just after Thanks Giving when the snow should be deep enough to start venturing off trail without risk of major carnage.

I rode the EVO kit last year, the MPI kit, and the MC express kit all on a 2015 viper. I did not run get any seat time on a Boost it turbo but I can say that the EVO kit was by far superior. No issues, always ran crisp and clean, and was the best fitting kit. EVO is also the only company that is smart enough to gain access into the ECU. if that does not help with the credibility of their company, I am not sure what will! They are the only company that can reflash the ECU with a higher rev limit as well as pull out timing and all that good stuff. They offer a naturally aspirated tune that is good for 30 HP with a header and can. No one else is doing that or can do that... For that reason I know the EVO turbo kit is the best one out there.
If you are in the market for a turbo system I would not overlook the the boost it kit expecially since they have a US dealer now. Boost it has a ton of kits out there and where the first to develop the kit before the viper even came out. I personally own one and can say they are Awsome and trouble free. With that being said the evops kit does really look like a high quality kit with great fit and finish. I just agree with you I have never seen one on the snow or heard of any one with one.

I am pretty sure Evo uses the Aem infinity for the turbo sleds. It's a good ecu with many great parameters... That being said, this will be my 7th turbo setup on a snowmobile. I've had some that ran great, and others that haven't. I know that all the fancy bells and whistles do very little to change the way the sled actually runs, and in fact the best running turbos I have owned have been the more simple setups. Of course the make and model of the ride made a difference also.
I do like the components that Evo uses. As I tend to like and see value in better parts(albeit its kept simple). But i would sure like to see others with first hand knowledge and runtime on them.
Christopher I am glad your machine is finally running good. I wish you would have been able to get more seat time last year. It would help to hear some positive feed back...

Trust me when I say NO ONE is more eager for a good base layer and some deep fresh on top of it to go our and RING OUT THIS TURBO install than me!

I have both the MPI kit and the EVO kit in the garage right now for our two Vipers and am half way through the MPI kit installation. I have yet to do the EVO kit and when I do there will be a video for those interested.
But having the parts and instruction manuals side by side I would MUCH rather do the EVO kit install as I would the MPI due to separator and thermostat relocation. Now my opinion may change after I install them both but I don't think so.
EVO install video coming soon.

Very nice! Which turbo from Evo did you decide on?

Base mountain kit with EVO reflash for turbo (rev limit to 9700). Hope to have real world testing info after thanksgiving weekend. Testing side by side with MPI turbo. I assume you want the results?

Lmao, I think everyone wants the result. Unfortunately that will be too late for me. I'll be making the decision between Evo and Boost-it within the next couple days...
Good luck with the installs!
If you are a competent mechanic, then pull the trigger on the EVO if for no other reason than they have the SUPERIOR ELECTRONICS PACKAGE.
EVO can do what NO OTHER COMPANY out there does, and that is tap in FULLY to the Yamaha ECU.
EVO can tune and control the 4 stroke fuel injected engine like NONE OTHER.
Their hardware isn't revolutionary.
But their Electronics ARE.

Well while I've always done all my prior installs, this one is being handle by a much better and smarter turbo guy then myself that happens to be a friend. If I go Boost-it then Eric at Racin Station will be doing it. So I'm confidant in the installs 100%.
We have already spoken with Jim about getting a kit. I am just skeptical being I cannot find anyone that isn't sponsored that has had any luck....
OK.
Try this then.
Go looking for guys that have some STRONG feedback on the Arctic Cat version of the big chute turbo that has been out for a couple years. This is where EVO cut their teeth and built up their reputation before diving into the Yamaha side of the equation last year.
There should be LOTS of people that you can track down with that kit.

Did you get any rides in that you can comment on run quality. More specifically fueling. While we all have our preferences on what size turbo, waste gate yada yada, what it all boils down to is run quality. I would be running the 275 end of Evo's tune. So did you get any amount of time on yours running it and if so how was it, in detail? You can even pm me if you'd rather..
We have done several kits last year with very good results. Like Christopher said the early kits got ridden hard and tried to break. Outside a bad batch of a few wiring harness the kit is second to none. We did the ball bearing billet models and only one just billet. Here is where the differences start:
1. No head shim.
There is no amount of tuning that can overcome dropping your compression. The only way to keep the quick revving 3 cylinder winding up like stock is to have stock compression. I rode a MCX Apex for 4 years, I am familiar with how the lower compression affects response. Can't say it doesn't. Some would be attributed to the rear mount turbo, but really it isn't that much different if you stretch out the Viper header straight. The physical distance is very close to a Nitro rear mount.
2. Selectable 210/275hp on a switch.
No one else can offer this when everyone else has a shim at anything over 240....and who wants a shim and be at 210 so they can also have 270? No one.
3. No extra injectors to tune.
The larger drop in replacements are tuned perfectly to the point of not being able to tell they are larger than stock. Everyone that says they can tell and then ride it come back with a different opinion.
4. There is timing done in the APC Evo uses to get around the need to have lower compression.
This year Evo is also able to reflash the factory ecu for added massaging of the timing and a raised rev limit. There is 1.5-2 hp gained in each 100rpm over stock. Whether you want to make use of that is up to you but it does make clutching easier with more headroom.
5. The hardware kit is second to none, the tuning is in class by itself as proven by the features they offer others can't. This isn't a slight against the other mainstream kits like Boost It or MCX. The fact that many high profile riders used the kit doesn't change the fact that they are still riding those kits with even more improvements with the factory ecu being accessible by Evo now. Who better to show the characteristics of a kit than the best riders. If it's good enough for TS riders Trennis, Dan, and Clay I would think it would suffice for the rest of us. What the specs state are better than the competition, and this translates to how the kit performs.
All the ones we did are rode on the 275 hp setting. Throttle response is crisp and right there as you would expect from a stock compression motor. There are several clips in TS14 you can hear Trenis's Viper on/throttle. I've ridden 310-330hp Evo 1100t SC kits on 3 different sleds I've owed over the last 4 years. That kit is a custom Garrett Tial ball bearing billet wheel built specifically for Evo. Response and tuning is perfect. This 3 cylinder motor brings throttle response to another level with the stock compression being a couple ticks higher than the 1100t. I would have never believed it could be more responsive than what I was used to...but it definitely is. The bottom end torque isn't like an 1100, but the quick revving is sure sweet.

I got ONE morning of running under high boost on VERY hard packed snow, nearly ICE conditions.
But.
I was running that morning under a severe LEAN condition as a result of poorly operating fuel pressure regulator that was not flowing the full load of fuel the ECU was calling for. That said, the power was absolutely EXPLOSIVE.
I would love to tell you I had several days of riding in deep powder and that it was the most amazing thing in the world, but I didn't and I can't say that. Right now, on a first hand basis, I just have FAR TOO LITTLE personal experience to make an honest judgement call on the final performance.
What I can comment on is that EVOPs seems to be VERY interested in getting this kit fully dialed in, and continues to work on refining the ECU program by continuously offering additional Flash Upgrades to incorporate More/Better control over the engine. My ECU is at their facility right now for the 3rd reflash in a year. Not because it is mandatory or that they were recalled, but because they have gained further insight into engine management and converted that knowledge into a new program for the ECU.
Understand, at heart, I am a TECHIE, this is what I do full time. As a guy who lives and dies by Software, I LIKE the fact that upgrades keep coming out and that the issues users report back to the company actually seem to be getting addressed and resolved! That to me is a big deal. Might not be to everyone else. But if you are going to go to the trouble of riding a Fuel Injected 4 Stroke, then you might as well take full advantage of all the technology you can get your hands on.
Still kinda odd the only people chiming in for you either sell the Evops kit or represent them or have little to no seat time on it. Personally I wouldn't over look the other kits out there. Some of the other kits have real seat time from day to day consumers those are the people you want to here feedback from. If u want feedback from myself or the group I ride with I will be happy to provide you with some. We all ride the same kit. With a full season of hard riding on them. I do not ride a Evops kit. Would like to ride with one but just haven't seen any out there.
Cheers

By all means let's here it regardless of which kit it is!
I also agree on the other parts. Perhaps there just wasn't enough of the sold to get a good review yet, who knows... Thanks for your two cents regardless!
