Push?

[owenbstory]

Ok let's try again . . . . . . . Can we get some unbiased, information on the push kit? I'd like information, instead of a dead thread. I know there are different theory's on all of this turbo kit stuff. I don't know what is available with all the different kits. I'm sure I'm not the only one?

Its a new kit for the Pro.

I have a cat, hope this still helps, I spent last year on a m8 push turbo plumbed out the tunnel, set up and ridden two years ago by mmsports. I was a hard sell on turbos as I like to ride in trees and tight canyons with lots of creek crossings...I was coming off a m 1000 that was set up to tear your arms off as it launched across creeks and bounced over the other side of the canyon.

Push was my choice due to a quicker spool up, more consistant powerband, and a little less coin for the ride. It delivers a very quick, smooth powerband which still lacks a tiny bit compared to my thousand on the bottom, but flies out in front after that.

I was very pleased to have a very trouble free year, my first ride out I had some trouble with some STOCK ac parts, nothing to do with push, and had a flawless year after that.

My two cents, hope you find a setup you like.
Since this setup, Push has added some great improvements that are well worth the look, I have seen and ridden some awesome Twisted sleds, but they were always thousands$ more than my setup, with which I have been very happy.

What I've gathered so far, I believe it is available with the vi-pec, I don't know if you can get it without it. I've read on the website that the artic cat kit comes with a throttle body on the inlet of the turbo, and pushes own ecu. I don't think any other kit dose it this way? The idea being that it is easier on the reeds and it offers less bottom end lag. Anyone other than a vendor have any real world experience with this? Looks like a third injector is involved to cool the charge temp. Is this necessary for a pump gas setup? Also the cat kit offers a bar mounted switch to run 2 separate maps? Can we please keep the arguing to a minimum, I don't want to stir up anything, feel free to pm me if you like. I'm just trying to figure this all out.

Fuel?

Idspud, what was your fuel consumption like? Compared to say, a stock 800 cat, or those that you rode with, how did it compare fuel usage wise? Full Race fuel or?

 

[IDspud]

I can run race with the guys, or pump with the girls, (wife and 5 daughters).

I just mixed according to how hard I thought I would run that day. Most days was two gallons of race, if the hills were bigger or snow was deeper for harder throttle, I would run more just for safety.

I carried four gallons extra, usually didn't need it. I averaged 2 gallons more per ride than stock sleds, very happy with the $ per ride.

I've ridden a new tbbt push kit on the '12 cat, set up by mmsports. It was last year-the first consumer kit on the snow- so it was not a vi-pec tuned set up. It had a BD box on it. I didn't like that an oil injection delete was required. I couldnt tell ya if the pro will be this way or not. There were some tps issues right off the bat and the sled did go down twards the end of the season. I was told from a gas quality issue, but I wasn't there when it blew nor did I see the toasted parts. The install was VERY clean and well thought out. The turbo spooled amazingly fast and had a solid pull as long as you could hold on. How much of the insanely quick spool was the tial turbo and how much was the throttle body before turbo, I couldn't say, but there was VERY little lag and once moving and in on/off throttle situations if there was any lag it was hard to find it. The sled had an appetite for belts which I believe was an issue allready just made more noticeable with more power.

Injection delete

The injection delete is defiantly a deal breaker for me, I burn through way to much fuel per season to be messing with mixing gas each time. Anybody know about this for sure? or on any other kits?

I took another look in the other thread at the pics of the pro push kit, and there is still an oil resivoir on the sled in the last pic. Not sure if that means 100% either way, but hopeful that there is oil injection.

They are to come with a split wire who will leave oil injection in place.

Does the VIPEC ECU make adjustments on the fly for temperature, elevation, boost, etc. as needed? Or can this only be done, by hooking up to a laptop? For example, riding at 7000ft, 25* at 8psi, sled running great. Then, ride up to 11,000, 25*, will the sled still be running 8psi or will the ecu bump the boost up to compensate for elevation increase? or is there a manual boost adjustment? I looked at the PUSH site, and unless I'm way off, it looks to me like the ECU does everything...can somebody plz explain how all this works?

The vipec can be set up to do everything including boost control...... It will take time to set it up and test it in the real world.

Push needs to let us know what is going on with there product, thay are missing the boat this year.

The more innovative and complex a kit is the more time is needed to develop it, they have got a lot of work cut out for them.

I would like to know what turbo they are using to keep the oil out of the intake track with the throttle body in front of the turbo

Turbos are said on their website. Say like this, have you ever hooked up a pressure/vacum gauge behind the trottles on a 2 stroke? Seen how much vacum there actually is?
My guess is turbos are holding up fine....

Thats a good point!

But have you ever put your hand over the intake of a turbo that was spooled up.

I haven't LOL, the system must work though and not suck much oil out

Have not, and don't think I will ever do
The idea has been tested before on 4S engines. If I remember correct, it was long time ago done on some Formula 1 cars. They got trouble sucking oil true the seals. But Vacum on a 4s is much higher ( or lower pherhaps if you see it that way) if I'm not incorrect.

 

[Boyko]

There were a few turbos in the 80s with the seals setup for a draw-through system for 4-strokes. The Pontiac Trans Am used a carb before the turbo, you just do not see that kind of setup anymore. Like you stated a 2 smoker is not going to have the pull like a V-8

 

[snow4shover]

A 2 stroke sled will have very little vacuum in the intake stock. When installing a turbo kit you will increase the vacuum in your intake a bit but it is turbo kit to turbo kit. The more volume between the throttle bodies and turbo the less vacuum in your intake. On push's kit when you install the throttle body before the turbo it restricts the air the turbo suck which cause a drastic increase in the vacuum between the engine and turbo. I was helping him work on his Cat stuff and we needed to pull fuel on the bottom end because of this. Dobeck currently doesn't have a fuel controller that can pull fuel on an Arctic Cat which is why he started experimenting with the Vipec.

no injection oil delete....retain factory system.

Vipec adjusts on the fly.

HM Turbos has the Vipec Pro dialed for you to run sea level to 10k plus on the same ride without changing your fuel our clutching AT ALL. No bed to every shut your sled off our raise your hood to adjust. Just keep riding.
