Mcx or mpi turbo?
- Thread starter revrider07
- Start date
Have you looked into the Evo turbos? My plan was to get theirs But funding was getting short. Every one else is using MPI around here ( which is a good kit ) but I wanted to be different. Mcx was another option for me but I liked the dual mapping from Evo better. Fred

Not sure what sled the turbo is for (I assume a new viper?), but I purchased a 2014 viper from Mark Leipheimer and it had a 190 hp kit from mcx on it. Its absolutely dialed both mapping and clutching. Best turbo sled I have had to date (I have had a impulse nytro and apex).
I was able to test ride the viper this spring, tried the MPI 190 as well as the local dealers 190MCX in 153,162, and 174 track lengths, hands down MCX, better throttle response and seemed far more powerful. Unfortunately finances didn't allow the new sled purchase this winter...
I'm going to build a viper and want the project right from the start. Going to be my first build in a fourstroke.. I'm leaning towards mcx.
MCX
Go with an MCX kit. This is my fifth year on one and not one problem. Also look at the yamaha swapmeet section. Anything other than impulse and MCX people are happy to drop there pants to sell there sleds.

MCX I've had a bunch of brands over the years and by far the MCX was the easiest to live with.

Have used MCX since autumn 06, never had an issue.
Superb power, quite with an meaty tone in Viper which is important, we have sound restrictions in Sweden, we don't want to close any more riding areas, people with loud sleds destroys for alot of people.
They also have some cool add-ons.
1. Their display, show all data in realtime, for ex: AFR, boost, rpm, WITH logging. And it add tuning (use carefully).
2. Bluetooth module, you see all info in smart phone but the great part: logging function. More advanced users can change maps from smart phone. Everyone have heard about Autotune, hook an laptop up and you can finetune maps with Autotune.
MCX have had 2 boost levels built in since 2006, cool for race days, but not used as "everyday" since clutching is a must when changed = the only reason i bought an Tapp clutch.

I've installed them all except Evo and owned them all and I'll take mcx every day of the week. From ease of install, power, reliability, and spot on fueling the mcx has yet to be beat in my eyes.

Need some clarity from someone who has installed the MCX. Their site says install time is something like 16 hours. That doesn't sound too simple to me, especially when an outfit like Hurricane says that theirs is like 3 hours. Obviously I am missing something?
I haven't seen a mpi kit yet seems like it's top secret on what's in it I have researched it is the Mitsubishi turbo the same as mcx? How are they fueling it? I've read stock mpi turbo at 4 lbs of boost doesn't sound like enough to justify cost. If you upgrade the this system how much boost and hp is it close to 270?
I can't remember for sure but I think when I looked at the MPI kit at a show a few years back they were using a 15G. Don't quote me on that it may have been a Push but anyways point is the G series is a much cheaper turbo than either the 16T or the 19T and it is a much older design. They were stock on mid 90's Volvo cars that ran about 5 lbs boost. Externally they look the same and you can convert a G to a T by switching the CHRA but for the price you might just as well buy a T series right out of the chute. The G series if I remember has a 7 fin compressor wheel and the T turbos are 9 fin.

Mcx 270
My local dealer installed a 270 mcx on my viper. It took about 19-21hrs, and looks factory. I had him install some extras like roll over valve, digital boost guage, belly pan, and snorkel intake. The motor can stay in on the viper, so that speeds things up.. Don't rush it, you'll be sorry if you do.
First test run out, it tried to rip my arms off! And then it did it again, and again!! So much for a break in procedure!
Speaking from experience, don't rush it.. It's a sled you can enjoy for many years.
