v6 vs ecoboost

[fordguys550]

On a work trip i had a 15 v6 051a package. My buddy had a premium eb. Obviously both auto. I beat him the first 2 times, he held till about 60 and i started pulling away. On the 3rd race, he got me by about half a car at 100. It was cooler and he was making peak power....turbos love that cool air. If your talking tuned eb, theres no hope lol. They are quick, even if they sound like a fiat abarth had a threesome with a corolla and a rx7...lol

Yeah mod for mod, eco will simply be better than v6. The only way a v6 would out perform Eco is if you add the procharger, and at that point you would be comparing the v6 to the GT

The 3.7 is good for a little over 300 to the wheel when you mod and tune it, mine made 295 and that's with tune, shortys, and intake I'm sure with some more mods we'd see 310 to the wheel...and that's about all you can expect to get out of the cyclone. Which is impressive but unless you are adding force induction eco simply going to be faster. really love mine for what it is though

I'd love to see how a Ecoboost with 100k miles on it competes with a V6 with 100k miles on it.

I have owned turbo 4's continuously for over 30 years. They have all been tuned with exhausts and intakes. They all accumulated well over 100,000 miles and two had mid 200,000 miles, never had an internal engine or turbo failure. After 7-10 years of ownership it was the body and interiors showing their age not the drive trains that prompted me to move on to my next car. I expect no less from my Ecoboost Mustang.

Since the v6 makes its power at a significantly higher rpm I would not be at all surprised if it shows more signs of wear at 100k than the 2.3 Ecoboost.

I highly doubt that. were shifting at 6500, tuned eb guys shift at around 6 right? not much difference there. and turbo cars internals are under a whole lot more stress than a NA car....that's a fact. cyl pressures get pretty intense on turbo cars....especially running 20-23lbs of boost, with high compression like the EB has. both cars run about the same rpm on the frwy, which is where all the miles come from anyways. time will tell how the EB does with age, probably do ok. the 3.7 has been around for a number of years, and has proven to be a solid motor, capable of handling 500-600hp at the crank without issues. my car is hella fun, I love the 6. ive spent time in the EB, and really didn't enjoy it that much, and ive had a couple turbo 4 fords in the past that I really loved. to each his own. with the new MPT tune, I got 34mpg going to work today, (driving 75, with a few stops in there)....300hp at the wheels, great sounding exhaust, great NA power band...yep...I love my 6

I made 340ish on tune, intake, down pipe. I never ran the car stock, but on tune only it was running mid 12's. I added tires and went 11's.

Made around 380 with E85.

Simple turbo swap and made 450.

While the peak power is nice to talk about, the torque and power curve of the I4 is substantially better than any NA motor- even the coyote.

Of course a Cyclone with a big single would bring that attribute to the V6 and would be a killer project, there's just not as much support there (not like the EBM and Coyote).

Since I'm off the V8 track for a little bit a turbo 6 had crossed my mind with the success of my I4 project. That's probably why I have a 3.7 sitting in my garage next to my Ecoboost

If I can sell this motorcycle I'll probably add a Coyote just so there is some auditory balance.

 

[fordguys550]

damn impressive numbers there. obviously, its been stated, there really is no comparing the eb with mods to the NA 6. I didn't get a EB because I don't drag race hardly ever anymore, and I cant stand how they sound.(even worse with aftermarket exhaust... IMO) this coming from somebody who had 2 turbo 2.3 (SOHC) cars when I was younger, and loved them

I tracked my Eco pretty frequently when the weather was cooler, but now that it's warming up, not hitting the track as much. But, with the bolt ons and 93 tune, it makes for a very fun daily driver that still knocks down 30+ on the highway. The exhaust took some tweaking to get it somewhat tolerable and not sound like a freaking Cessna..lol. I'm still going to add a pair of Vibrant resonators to mellow it out even more. With the catless DP, mid-mounted Full Boar muffler, and rear muffler delete, it has a nice low rpm grumble and zero highway drone. I'll end up having to redo it all if I ever go to a turbo upgrade...ugh. But, it sounds/runs good for the time being.

Nahh Turbo upgrade would only require a DP at most.

I love the sound of the MAP resonated exhaust with catless DP. I will go for the Vargas stage 2 so I won't have to get a new intake or DP, just a striaght 3 inch coupler from the intake to turbo :thumb: i think those are at 400ish whp on 93 pump.

Theres a company workibg on a twin turbo kit for the 3.7 using stock eb3.5 turbos from f150s..if that kit comes out, should be pretty affordable, and make rediculous amounts of tq in the low/midrange. Honestly i think ford hasnt done a ttv6 in the mustang yet because they know it would be the end of the v8 lol. Hell even you 2.3 guys are faster than alot of the gts already lol

 

[mustangv6magn]

dude it would be awesome for someone to tt a v6 I would love to see it. if it happens I might just save for that instead of starting a new loan on a gt

There may be more stress in the turbo motor but it is designed for it so that does not become a factor in the longevity. Unless you get into larger turbos there is not much point in shifting higher than 5500 rpm with an Ecoboost. If you drive like a nanny all the time either engine will last 100s of thousands of miles. But if you are trying to get max performance out if the engine the v6 you are going to be consistently spinning the engine an extra 1000 rpm which is a significant increase in piston speed and that is where your wear comes from.

Both engines are amazing performers and no one is going to convince me that there is a long term penalty in durability with the Ecoboost, my 30+ years experience with turbo 4s is all the proof I need.

There are already quite a few s197 TTV6's running around... it's only a matter of time before someone brings an S550 to JMP for twins. I think one of Jack's s197 with twins made something like 550hp on 93, well over 600 on e85. Stock block, no mods other than the twins.

That's cool. I don't race but just to have the power there when you want it would be nice.

 

[fordguys550]

seeing as how the 3.7 uses the same bottom end as the 3.5EB, im not worried at all. these v6's have made some pretty insane power on the stock bottom end. weakest link are the pistons, but with a proper tune, they can handle a lot of power.

btw, these motors were designed to rev high....just like the eb was designed to take boost. factory spec says peak hp at 6800. nobody is spinning these past 7k..so were not really revving them any higher than recommended by ford.

this is all a mute point anyways. you like what you like, and I like what I like.

 

[fordguys550]

infact, theres these crazy guys in TX running a stock S197 3.7 (though I heard its built now) they were making over 600hp at the wheels, and then they were spraying on top of that...so maybe 700 at the wheels.....on a stock motor. single turbo, around 14psi I think. maybe e85 but not sure. in any case, if the 3.7 can handle that amount of power, it must have a pretty damn good bottom end...and it does
