2015 Mustang Ecoboost K/SA?

I didn't hear them say what octane fuel they are running.That makes a huge difference in the tune. Most likely it has stock rear gears.

I would say that car is probably at the heavy weight limit for K

Yeah, that's a Performance Package car. They come with 3.55 rear gears instead of 3.31, larger/heavier front brakes, 19" wheels instead of 17" wheels, and some other doo-dads.

.33 off the K/SA index. With an off-road down-pipe and no exhaust system, that car would probably be under index.

Does it need a roll bar for K/SA?

I am just trying to get this whole conversation clear in my mind, is this being proposed as some sort of cheap and easy way to build a Stocker (which it absolutely won't be)? In my mind there are an infinite number of better and cheaper ways to approach Stock class if that's the plan, buying someone's complete finished car comes to mind. Or is this just some sort of philosophical debate (which often happens on Class Racer)?

Cheap way to build a Stocker ?....No

Easy way ? Not really if you plan to pull the interior out yourself to add a roll bar.

Philosophical debate ? Maybe...

...Or maybe the OP wants a Stocker he can drive to and from the track.

In the end, it's not a cheap Stocker

Like Alan said, it will not be a cheap Stocker.
Someone will take their street car, do a few mods, go under the index.


Then there will be the hardcore racer that will buy a one, strip everything out, build a killer engine, destroy the index and put it out of competition.


Lets not forget what happened to the Buick Grand Nationals...

Does it use something like a waste gate to limit boost?

If they will make this FWD conversion SS/GT legal, I will be more than happy to beat on the SS HP rating, I'd love to do it. Already have the chassis, just waiting permission to stick the motor in. I already requested the chance to make the change so I cold run the 2.3 single cam turbo motor for the same reason, just not having any luck getting NHRA permission. I will stay in SS/ES for the time being.

This is what I was thinking:

Used 2015 Mustang Ecoboosts are not nearly as hard to find as other less-expensive-ish Stocker candidates like a Pinto station wagon.

Being in the middle of the alphabet, it's faster than a lot of other less-expensive-ish Stocker candidates.

A used 2015 Mustang Ecoboost would not require a total body/paint/interior restoration, like a lot of older Stocker candidates would, just to have a suitable vehicle to start building a race car from.

I thought that I had spotted a combo that would not require a lot of work to get it to comfortably run under index. For me, I felt that would be enough- I don't intend to set any records or race any national events.

Anything M or faster is going to require a roll bar, and as some others have pointed out, it could be a good idea to install a roll bar even if not required to, simply because you may be racing against 170 mph "Stockers". So the work of pulling the seats, carpets, and some plastic trim panels, wasn't really a consideration. It also would give me access to be able to remove some of the sound-deadening materials while it was apart anyway.

And because it's a car that (at this point in time) appears to be capable of running under index on street tires with minimal modifications, it looked like an opportunity to skip the truck and trailer, which would make it a LOT less expensive than doing it with a truck and trailer. It would also be one less vehicle to maintain, and take up a lot less space at home.

It is not a philosophical debate- I have no desire to argue with anyone here. I have drag raced for many years, but have never class-raced before. I recognize that there is a lot of knowledge here- discussing this issue here seemed like a good way to be able to benefit from that knowledge.

But if there is the very real chance of a "Baby Jet" killing my action, then I would not want to waste my money pursuing it.

Do you want to win rounds or just be sub-index? There is a difference between the two. I would propose to you that when it comes to turbo combinations, a street legal car and a consistent bracket racer (which is what you need to win rounds) are likely two different animals.
