EVO Upgrade Kit for Factory MPI Vipers are coming soon

Evolution Powersports · Jan 14, 2016

Evolution Powersports has developed an upgrade kit for the OEM MPI Viper Turbo Kits.

Our kit is designed to upgrade the boost from stock levels for the factory kit to 9 lbs (true) of boost at any elevation. The kit includes a set of (3) 550cc direct replacement, plug and play fuel injectors, a boost T for adjusting boost pressure (electronic boost control is optional) and an ECU Reflash which changes the timing to a more boost friendly curve, raises the rev limit to 9800 and corrects the fueling for the additional boost. This kit is 91 Octane safe.

The basic kit with will have a retail price of $1199.00 and is a dyno verified 35 horsepower gain over the OEM kit. Also, this kit is EXTREMELY easy to install - it can be done in less than 30 minutes whereas fuel pump upgrades are very difficult and time consuming on the Viper. The larger injectors are capable of supplying enough fuel for 260+ hp with the stock fuel pump and regulator.

The kit will be easily upgrade able as we plan to develop a Stage 2 with 250 horsepower for next season which will consist of an air to air intercooler and more boost.

Eric at the Racin Station and a few other select dealers will be testing the kit within a week or so.

Dynos and videos of the dyno and field testing will be posted soon.

Sweet!

Its nice to hear there will be a way to upgrade that dealer kit with ease. EVO has great products and customer support.

Few questions.
1. Will this work with the MPI EBAC as the 2016 factory kits come this?
2. For the guys running a 2016, will you be offering a "fix kit" for the rods? (Rumors are that MPI will have a fix kit available sometime)
3. Will clutching specs be available, or are consumers on their own?

We have not done any testing on the 2016 models yet.

Clutching recommendations will be provided or a complete clutch kit will be available as an option. More than likely only a primary spring change will be necessary.

GEMS

I take it the GEMS will still control boost fuel?

RACINSTATION · Jan 16, 2016

Yes, your current fuel controller will still be needed to add fuel at boost.

We are doing some fine tuning for this kit before we make the kit available. Hoping this kit will be out to our consumers by the end of Feburary if not earlier. Feel free to ask some questions.

All yamaha viper with MPI turbo kits stayed tuned...... this upgrade Kit will be available in the next couple weeks.

Is their any benefit to this kit if you've already done the mpi stage one upgrade?

apex 9420t · Feb 26, 2016

Hello!

RACINSTATION · Feb 26, 2016

Yes, of course there are benefits if you have the stage 1 upgrade. The rev limiter is raised and timing has been altered. Bigger injectors allow for higher boost levels.

Hey guys,

A little update for you, we have been working on this kit however we have had quite a few set backs that are keeping us from finishing it. The sled we have been testing this on was a higher mileage sled and had parts failures keeping us from finishing the last little bit of tuning needed to release this product. We are working on getting a brand new sled setup for finishing this kit.

We have the kit ready to sell for low elevation setups. Above 6000ft elevation we have a stumble we are trying to get out before we can set you guys up. Were so close, it just needs that last little touch to be perfect.

Thanks

Was it internal engine failures? Not trying to stir the pot, just curious. If you don't want to comment it's fine and I understand.

I have been with a couple of times when they were working on this project. I know a lot of time was lost when a stock header blew out and wasn't caught for a while. And the last time I was with the starter went out. Id call it crappy luck, some things ya just cant control.

Any updates on this kit Evo and would WKM in Alberta Canada be able to do the reflash on the ecu, eabc and gems boxes and supply the rest of the kit as I'm in BC, my riding ranges from 3-8000' but will be primarily 5-7000' and what hp levels will be the ceiling with the stock MPI charge box and what would they be with your upgraded intercooler and will the 180/190 standard MPI turbo and waste gate be able to support this without any changes?

We have all the flash tools needed for any Evo flash files, dirt or snow. We flashed Vipers this last fall and winter. We will have stock on the kits when they are made available just like the rest of Evo's parts inventory we normally carry.

Any update on this? I am very interested in this reflash. If I'm gonna do the reflash to make it start and run better might as well get the hole deal and have more boost. I would also like an intercooler aswell. Some vids of the upgrade would be great also.

The upgrade kit is available but not released on our website yet. With any questions regarding the kit give Kyle a Call at our shop. We are also working on an upgraded intercooler kit for it as well. Hoping to have everything finished up for it very soon.

madsledder · Jul 8, 2016

looking forward to this. I would assume it will come with the other fixes as well. I am very interested, keep us up to date on the intercooler also. Will probably get it too.
