Mountune Fiesta MRX Turbo

[Se7eN]

can u run e40 on this setup with a custom tune? just read other posts and some people say you run out of gas ??

you'll need port injection just like any other bigger turbo

 

[Se7eN]

just curious as well anybody try the full e85 pump yet ??

not necessary for Port

 

[Se7eN]

ok I get it on the fuel now so upgrade the pump from woosh or injectors or both then or the single port is good enough I really only want to end up in the 280 range I only have e85 and 91 available to me here as well. so far the numbers on straight 91 where not very impressive to me for me to drop 2k for a few hp. heres hoping im very wrong

Even with Single port and E40 you should be able to reach your goal. Most likely more depending on the weather and tuning. Also the altitude will probably not help.

What's the point of new injectors then anyway, has anyone ever tried them?

 

[Se7eN]

In UK they have used them. That's about as far as I know.

They have been in "Testing" for quite some time now....maybe it will come to Fruition one day.

A single port would be fine but honestly if your gonna go that route I would look into the s280 or a 2860 as you will also run out of turbo fairly quickly. you should be able to make close to 280 on 91 and could on an e30 tune with lower boost and more timing. The injectors are not gonna be worth for most people unless you switch back between 93 and ethanol alot. you dont need a lpfp to run full e85 if you have a 4-port, but it will strain the lpfp a fair bit, its designed to flow petrol and be lubed with petrol.

I know that....But no one has come with definitive evidence with Results to show as they have been out "Testing" them for a while now. Get what I'm laying down?

That's actually pretty decent, a Vdyno on 3rd gear gets me around 252hp in 90 degree heat and crappy gas "93oct"

be aware my whoosh hybrid in summer 95 degree weather made the same 265whp on 93, stock fuel system,

Thats why Vdyno has to be taken with a grain of salt. On a real dyno my car makes 270~ whp on 93oct in 90 degree weather but does not break 250 on a Vdyno. Its good to see how progress is going but its not real. Not by a long shot.

is this needed with the mrx turbo kit or can you use the em dv2 (the electronic bov)

Yes you will need a mechanical BOV For it.

The sound symposer one is most likely the best choice....

Turbosmart CEL Defender plug TS-2301-4001 is required for those not utilizing a tuning device.
is this for people who don't have accessport? or is it also required? just want to make sure I would like to have everything ready before trying to do an install just to find out im missing something.

Your tuner can Turn it off or you can buy one of those if you would like.

ahh thanks for the info I was planning on using the tune that comes with the kit or so I heard it comes with one.

you can use that, or I made an adapter for my stock one

It all comes down to variables. I have Vdynoed cars that read higher than local dyno and cars that read the same and some that read way lower than a Regular Dyno. That's why I say i take it with a grain of salt and never look at it as the actual number. Even dyno numbers themself should be taken and used to see the gains of mods, many read differently. Some lower, some higher.

I'm more than happy with my stock turbo and the 271 ft/lbs of torque at the wheels with NO turbo lag and reliability!
