We picked up my friends wifes 2020 Viper!!

Not sure if this has been solved yet in other posts. But does the 2020 still have the arctic cat ECU?

It sure does.

This is the one that gets me going. Can you imagine 2 intakes right to those vents on front!

Does it look like those are Frogskin Vents Mr Sled?

yes just like the sidewinder!

I'd be proud to own one if it had the nytro motor and ecu, nice sled regardless

I thought it did have the Nytro motor in it with the Cat ECU? Does it have the not as aggressive cam Vector motor in it instead? I was hoping that they would have had the 2020 Viper finally to where it should be!

I wonder if there would be a noticeable increase in underhood temperatures if even part of those vents were used to direct air into the airbox.

Probably. So add vents to front nose piece where we have them now.

Yamaha made that pretty annoying to do since they added a plate in the way! It's never easy, is it?

I thought it's the same, but others claim it has different cams and that's why it runs out of steam on top

Just feels that way. UTV guys put Viper cams in for performance increase. So don’t believe that one either.

I don’t see a plate in way. But nothing is easy as it seems. From the pics it sure looks to me that this new system breathes more hot air than previously. The whole lower nose is blocked off. Airbox stock intake hole is bottom front like always. That means all intake air is heated by radiator. Would definitely want try changing that. Look at pic showing the screw hole then look at same old style piece here.

The plate isn't in the lower black plastic (even though that too is sealed off relative to the 2014 to 2019 Vipers). The plate is basically underneath the front radiator and has what appears to be a coolant hose running through it (basically look at the picture between the front bumper and the radiator). You'd either have to unrivet and cut this plate out of the way or drain the radiator and pull the tube out. Nothing that is really considered 'easy'.

Yea they really sealed it up in front. They must be attempting to heat intake air. Wonder how it will work with steam in it !

If you look at the pic I posted with red lines on it those lines would be where I would run tubes from box to the side vents.
