Oh well, these things happen in testing.

And, approximately what power level were you at?

I'm just gonna go out on a limb and say, less than an FA20.

I don't know the exact number, but somewhere north of 510whp.

That being said, I had absolutely no interest in an Ecoboot Mustang and have still been religiously following this thread. Had no interest, past tense. Well done!

I've been interested since I first heard they were going back to a 2.3l turbo 4 cyl. I would really love for them to switch to the 3.5 ecoboost, but the performance gains from a SOHC 2.3 ford turbo from the 80's were almost on par with what they're getting from this one.

If this one proves to be close to as bullet proof as that one, I'll really like it.

I may even consider swapping it into my twin.

Just read this thread based on @Bergen23 commenting on the gains, holy shit

Showing my EB 'Stang buddy

Sorry for the lack of updates. We have been busy with the WRX and Fiesta ST projects as well. But we haven't given up on the EBM! We decided to pull the engine out and build it for some bigger power. We went with a full sleeve, I-beam rod set up. Still using stock compression ratio. The cylinder head is still stock at this time for now. We have upgraded to a 6266 and a larger "race intercooler". Here are the current numbers as of last night. We hit the limit of the stock 3-bar map sensor at 27psi. We are going to be installing a 4-bar and shooting for 35psi shortly which should get it into the mid 600's.



Here is one of the earlier pulls from the day

Just thought I'd revive this thread a bit - I have to say, I've always been on the fence about Mustangs, but this thing might just sway me over. Could be my next automotive investment - just tremendous bang for the buck. I know it's still early but anyone drive one of these yet?

I can't wait to drive one next Tuesday at Sebring. Then to ask when they are doing the same with the Focus RS!

Probably not raw enough for you.

Be sure to post your impressions.

I drove the car a while ago. Reposting from another forum:

I only did 3 laps on the GT350R, it was my first time at Laguna Seca IRL, and I'm an average HPDE driver. My impressions:

- I expected to be pinned into the back seat smashing the throttle on 2nd gear but, somehow the car didn't actually feel 500HP fast to me. Very smooth power delivery with no drama, probably thanks to the massive tires and the 3750lbs curb weight with two persons in it. Mind you, I got the same feeling when driving the F8x M3. You don't realize how fast you're going until you look at the speedo.

- Power seemed to peak well before the 8200rpm redline. I don't know, last few hundred RPMs felt a bit underwhelming. But I'm used to peaky NA cars (S2000, FR-S)..

- Engine and exhaust sounded amazing, I'll give it that. It's actually not that loud inside the car... sounds better outside than inside

- I liked the Recaro seats a lot. But you're sitting so low (for a Mustang), and the hood is so high, that it's very hard to place the front tires with confidence and accuracy. Not a big problem in most corners, but going down the corkscrew was scary, not knowing how close I was to putting tires off the track. I assume more seat time in the Mustang and familiarity with Laguna Seca would alleviate this. Again, I'm used to cars with great forward visibility.

- Steering felt good. I was surprised by how small the steering wheel was. Wish steering ratio was faster (but I say this of most cars).

- Nice shifter, relatively long clutch travel with no feel for engagement point. But overall intuitive and very easy to drive. I remember heel and toeing was easy too (much better relative pedal placement than my FR-S).

- Tons of grip. 295F and 305R tires, honestly I didn't come close to exploring the lateral grip limits of the car. Neither did my instructor, who seemed to go barely 6/10ths on my ride along lap (still much faster than me!).

- Handling wise, it had the classic FR balance, very predictable and easy to drive.

- I'm not sure what the damper settings were, but the ride was extremely smooth and going over the the rumbled strips, you would get more feedback from the steering wheel than from the chassis.

- Great stopping power, although I didn't work the brakes as hard as I could have, out of respect for the instructor . But this was one area that was certainly confidence inspiring. Braking was never a worry.

- Car does looks great in person.

- Drove with TC on, it kicked in a couple times, in a rather obvious way. I remember the M3/M4 electronics being way more subtle, allowing for some small, controlled slip angle and making you feel like a hero.

Overall, a very fast, obviously track ready car. Even though I felt connected to the car, it felt physically big to me and the poor front visibility made me slow down in many places to ensure I didn't put wheels off. I personally like smaller cars. It's funny because when I drove the F8x M3, I got the opposite reaction: the car felt smaller and lighter than it really was.

For sure, the best muscle/pony car I've ever driven.


(We were not allowed to record video inside the car. Bummer.)

Oh god this car looks incredible. 0-60 in 3.7, 1/4 mile in 12s flat.

No boost, no problem.
