LMR 2018 Mustang GT Auto PP1 Dyno numbers (VIDEO W/CHART!!)

Dub347sbf · Oct 30, 2017

I saw this while browsing twitter. Looks like a PP1 10 speed auto put down 415HP and 397 lb ft on a dyno!

From YouTube:

LMR.com is honored to provide the world with the FIRST dyno numbers of a 2018 GT with the new 10 speed automatic transmission!

This car does have the level 1 performance package and is rated at 460HP and 420LB/TQ at the fly wheel.

Stock Dyno Pull: 415HP/397TQ at SAE
- 93 Octane
- 10 Speed Automatic (7th Gear Pull at 1:1)
- 19" Rear Wheel w/ 275/40/19 Michelin Pilot Sports
- TOTALLY Stock Car

*Note*
The car's VSS did limit us on our pull. This is why you see car tap out at 6600 RPMs. The redline for the 2018 Mustang GT is 7500. On that note, the car does have room on the table for potentially more power!

Edit: Thanks Ziad!

Hey guys, this is Ziad from LMR.com. Just wanted to jump in and include that the numbers are SAE corrected.

Adding video and some LULZ

Well 460-15% for a manual is like 390. So either under rated or the auto has less than 15% loss.

Is this really pushing 490-500 crank?

I didn't realize the loss percentage was that high. I thought it was around 10%.

Does anyone know or remember what the 15-17's were dyno'ing at?

Unless it's changed over time manuals have usually been like 13-15% range and auto's about 20. I wouldn't be amazed if they have improved some.

Curious to know if the correction factor was STD or SAE and what the temps were in the building at the time.

Seems a bit high for the official Ford rating, but I imagine they are underrating the engine quite a bit. Slightly more displacement, better flowing heads and a full point of compression should be worth more than the 25hp increase Ford has rated the engine over the Gen 2.

My guess is that it's pushing some 470 fwhp and the transmission is more efficient and only losing 12%.

No way.

Auto's have been losing closer to 10-12% for over a decade now.

New cars are probably around 12%. People like you say 15% or more just to make it seems like the motor makes alot more power. We'll know true power #'s once we see trap speeds.

No, I say 15 because on average thats what some out to the proper crank numbers.

The Mach1 was rated 310hp and they on average dyno about 265, that's pretty close to 15%. If you look at most dynos, to gather an estimate crank number they all still multiply by 1.15. 15% is the standard still for estimates.

Even if it was 12% losss for a manual, that means the Auto would have to be just 10% for it to make that power at the wheels assuming that its really a 460HP engine. Somehow Ford has made the most efficient auto I've ever heard of, or its under rated.

That's extremely stout, under-rated and/or a SUPER efficient tranny ...

% loss and resulting (calculated) FWHP:

10% loss = ~460
15% loss = ~488
20% loss = ~518

Since when? Even in 2012 5.0 comparisons I see people with 10-15whp more on manual vs auto. I've seen valid arguments for Manual doing 12.2257, but I've yet to see many or any dynos of an auto putting down the same or more than a manual.

HP peaking at 6,600 is interesting. I thought this one was supposed to make power beyond 7K? I'm going on on a limb and saying those are uncorrected numbers during a 40° day..LOL

I'm thinking it's a combination of both. I wouldn't be amazed if its something like 475-80 with a 13-14% loss. I'm expecting to see a manual do about 420 wheel. The gap is really closing between the two.

Looking at 2015 Dyno sheets, looks like it is still a shift up by a couple hundred RPMs. I sent a tweet to LMR for some clarification on the temp and if they are corrected numbers, I'll update the post if they reply.
