I know I know, were not talking about a supra, but this thing sounds badass!!

the argument of a v6 not sounding like a v8 is valid, but a v6 can sound awesome. I put in air conditioners for people, high efficiency, top off the line stuff in some cases, and theyre always worried about seeing it. I tell them to be proud of efficiency.

 

That's no v6...

FI straight six power.

 

Oh really...

The Roush Phase 2 kit costs $6650 and adds 210Hp and 150 ft-lb to a 5.0. What Roush doesn't say is if these numbers were taken with their $650 exhaust system in place. I suspect they had done some exhaust work to the truck but didn't include it into the price. The real cost for the complete Roush package is more like $7300.

Full Race added a tune ($370) exhaust ($699) and new intercooler ($1100) and added 175Hp and 300Ft-Lb.

So for $4500-$5200 less the EB with on bolt ons makes 200Ft-Lb more torque and only 30 less Hp as the 5.0. I would put my money on the lighter truck with 200 more Ft-Lb in a race. How's that more potential working out?

 

Let's see - have any of you V-6 haters ever driven a 3.7 Mustang? Oh, that's right - it's a girly car. 305hp doesn't mean anything even though it's more power than a stock 4.6 Mustang ever had..........

 

This thread has wandered off so badly that guys are posting vids of supras lol...

 

Who buys a v6 mustang to dump money in it and street/drag race.... Most just buy it bc it's a mustang (cheaper than a gt) but yea it does get up and go. The 4.6 2v was a boat anchor in stock form (had one) minus the 4v 4.6. By the way I had a 4.0 v6 ranger that I beat and that truck is still running with the orginal motor has over 200 thousand miles now (know the current owner) so if it's built like those motors were I would drive it but rather have a v8. this thread has went off topic lol they all have blue ovals in the grille is all I care about each to their own.

 

Hahaha. Oh yeah. I forgot the supra was a straight 6. Still sounds sweet

 

.. I just like to poke fun at the 5.slow guys every once in a while.. Most take it pretty well

 

I think the funniest thing is that you test drove the 5.0 and the Eco and didn't notice any difference, if I remember correctly. You might've even wanted a 5.0, but the Eco ended up being optioned and price where you wanted to be at the time, so you came home with it!

 

Glc, the 3.7's are still slower than 4.6's and the 4.6's have a lot more torque, which is more overall power because it makes up for the 5 less horsepower.

Wookie, I still wouldn't trust a race tuned EcoBoost. They just aren't stable/reliable from what I've heard and seen. Full blown race tunes on anything with forced injection is asking for trouble (ie. all turbo diesels). Do you think a 75% increase in torque is safe when all you've done is a tune? I doubt it. A fully done supercharger system is relatively reliable. Also, don't forget the $1500 premium for the Eco. So that comes out to a $3,000 ish difference (because Roush cat back exhausts don't do crap for performance) and one is more stable than the other.

Larger displacement ALWAYS equals more potential to some extent. Take a full on race built 2.0L 4 cylinder motor with a huge turbo and it produces 500 hp. Then take a full on race built 4.6/5.0/5.4/5.8L V8 and it'll produce 1000 hp. Or, for less money than the completely built 4 banger, you could take the V8, do some things to it, and still end up with 500 hp. All while having lower maintenance and higher reliability.

I don't know what tone it sounds like I'm using, but this is purely conversational! I'm just replying. I don't want anything to sound confrontational

 

It may be where i live but i have not yet seen where they actually charge the extra 1500... Meaning when i was looking all of the texas towns for a new truck the Ecoboost's where exactly the same price if not cheaper... Thats how i got my truck, drove a 5.0 xlt with the chrome package but it didnt have the locking diff and a few other small options.. Then right next to it was my Truck that had more options and with the ecoboost for 1200 dollars cheaper.. Now i do like my ecobeast BUT i wouldnt pay an extra 1500 for it, if that was the case id be in a 5.0

 

Not sure about the not noticing any difference between the two, The main difference i noticed between the two is the take off torque, i hit half throttle from the stop sign and the 5.0 moved nicely up to the speed limit, but when i did the eco the same way it took off alot quicker (of course after it hit boost) Theres nothing wrong with the 5.0 and like you said i was ready to sign the paperwork but got a better deal on the eco with more options. I sure like the sounds of them turbos!

 

Change the tunes to Livernois (sp?) their numbers are pretty close to what Full Race claims. The bottom end of the EB is stout and could handle a lot more power easily. Since when does the EB cost $1500 more than the 5.0? When I bought my truck it was a $750 option but between X-Plan and EB incentives I only paid a $100 or so more for it. At stock levels an exhaust system will only add noise. Once you add a bunch more air into the 5.0 it will need to go somewhere and the exhaust will need to be cleaned up. Any what you want to spin the numbers the EB will be considerably cheaper to get to the same output. That's the nature of FI from the factory.

This would hold true only when you compare apples to apples, in this case we're not. The 5.0 comes from the factory with a pretty high CR and port FI. The EB comes from the factory with a little bit lower CR and DI. The DI will let the EB see a lot more boost safely. With the CR of the 5.0 there's not much room left to add boost before something will have to be done to address the detonation issues. You could either run race fuel or modify the heads to remove compression, neither will be cheap. Meanwhile the EB just needs bigger turbos. I know on my S4 switching from K03s to K04s will add a gob of power (100+ depending on which exact ones). The factory turbos on the EB are also K03s so I suspect the bump would be greater due to the size difference of the motor. This could be done to the EB for less than the current difference in price using your numbers and Audi parts prices.

You can make just about anything fast if you throw enough money at it. In this case the EB can be made faster for a lot less money.

 

Bunch of know it all's in here...

 

The thing that gets me is I keep seeing 600+ who mustang 5.0s in signatures on mustang forums with blowers. I'm looking at them so doing more research... Motor can handle some power.

I'm not getting into it with anyone but wookie does have a point on the CR... FRPP sells a low cr 5.0 for boost.
