180 kits..Push vs MCX

[Keithcat]

Does anyone have any information about the Push turbos? What turbo is being used ect. Is it a good kit? How does it copair compare to the MCX?

I have been looking at the 180 kit here for the past few days and the MCX for me is quite a bit more. After the kit, shipping, clutch kit its about 1250.00 more.

The Push turbo from my dealer is being offered to me for pretty good deal at 400 hundred below retail.

Just looking for your opinion.

There is another thread here that covered the push turbo. It isn't all inclusive, but its all I've seen on it so far on SW:

I think you'll be fine either way. I doubt the factory would support a turbo kit that wasn't well tested.

If your a MCX dealer and have little wiggle room on the price please PM me.

Thanks

You should say where you are from in your profile. This will help dealers in your area give you prices on kits, install, etc.

I went with the kit alpine is selling.. a kit made by trask performance.. after reading bout it.. and installing it.. would recommend it.. no question.. haven't ridden it yet.. but alpine stands behind it.. as far as push vs mcx go.. wouldn't hesitate to spend the money on the MCX kit.. heard that the turbo on the yamaha kit is a garrett rip off.. just my 2 cents.. spend the extra money on a proven kit.. get the mc kit

 

[Ak_7vytr0]

have not read a single bad thing about the mc express kit.. guys that have it.. love it.. 180 is more than enough horse for most people

Thanks for the replys.

My views:

Push Turbo

Neg: Its a new kit to the market and is not proven at this point.

May or my not have a lesser quality turbo unit.

Its on backorder until November.

Only able to run over 6000K ( may be a yamaha thing )

Pos: Price point is perfect.

Able to keep warranty on my sled if something should happen.

Bolt on off with only a hole needing to be drilled.

Includes a clutch kit.

Made in the USA


MCX

Neg: Warranty will be voided on my 12K sled.

Cost

Unable to purchase through my dealer.

Have to cut and weld my exhaust.

Pos: Proven kit! Turn key and go.

It appears the kits are in stock right now with dealers.

Lots of online support from other customers.

All elevation kit.

Upgradeable to 240 up.


Im located in Michigan if any local or out of state dealers want to quote me a MCX kit shipped to 48313

I know the MCX has a altitude compensater to maintain 180 from zero to 10K plus.

Does the Push adjust for altitude? Or is it 180 at 6000 feet slowly loosing HP as you increase.

Good question?

From what I have heard from out Yamaha dealer reps the factory warranty is void if you run the machine under 6000 feet. This leads me to believe the push kit is a set calibration for that altitude. Any failures on a machine with this kit will be heavily scrutinized by Yamaha before any warranty repairs are carried out.

push turbo

I am assuming that yamaha has extensively tested with the push turbo. I don't have a nytro but i am interested to hear how they are handling the fuel injection. I would thing a new ecm with a new map Sensor?

Any idea how many lbs. the Mcx 180 kit runs at 9,000ft. The boost compensator things gets me to thinking. Maybe this kit puts our more power than one might think and that why everyone loves it so much. Maybe at high altitude its notching the boost up higher than I thought.

Does anyone know what turbo's the push and mcx run?

Not sure on the stock boost levels.

However I do think that is the way MCX works. Say 2 lbs at sea level 6 lbs at 6000 feet and 7 lbs at 8500 and then 8 at 10 K ect keeping the 180 hp level all the time.

Clutch it once and it's good at any altitude.

What I dont know is if the Push turbo has this feature.

There is a post on here by TBird that explains this feature but ya your right on the money. The boost will change with altitude, I can't explain it but he made a nice little graph that shows how it works...pretty cool stuff!

Thanks for the information guys.

The way I understand the MCX system is that it starts with say 4 lbs of boost ( or whatever) at sea-level to get to 180 h.p. As you raise in elevation the air pressure lessens but the system compensates this by adding boost to maintain the 180 h.p. This is why you never have to change clutching, as far as the motor is concerned you are always at sea level. Really I guess the fuel map never changes either?

 

[torqmonster]

The mcx 180 kit runs 6 lbs at sea level, approx. 7 lbs at 2000ft, and about 8 lbs at around 4500 ft. So, it looks like the boost goes up approx. 1lb for every 2000ft. There is a chart somewhere that has the exact numbers.

 

[Keithcat]

Good info.

My last turbo was on a V-max 4 many years ago. This style turbo used the vains in the turbo housing to adjust the flow of gas around the impeller.

With the Garret ( automotive style ) turbo what controlls the boost in relation to Alt? Is it the built in waste gate that opens slightly to control the amout of gas to the impeller. Almost sounds like a boost controller. Is this what the MCX has? Does anyone know if the Push turbo has this feature?

I know on the supercharger the boost is fixed. So as you go higher one would assume you start to loose boost pressure. Unless you change the pulley.

Does this sound about right?

The mcx kit measures atmospheric pressure + boost and compensates with boost as the atmospheric pressure drops,
maintaining total pressure. The result is no mater the altitude the total pressure the engine gets always stays the same, fuel map stays the same, the hp stays the same and the clutching stays the same. Supersmart!
