Official 2018 gt owners thread, if you bought 1 check in here!

Additionally, I'd like to raise the hypothesis that powertrain loss does not increase by the same factor as horsepower increases.

For example, say you have a stock 385whp 2017 Mustang GT that then receives a Whipple supercharger and power increases to 600whp on the same dyno. If the stock dyno run is accurate, 385/435=0.885, or 11.5% drivetrain loss on that exact car/dyno. Once the Whipple is installed, we use the same loss % and find that 600/(1-0.115)=678. How did power lost increase from 50hp to 78hp? A 36% increase in loss through the same drivetrain?

Now I certainly don't think the powertrain loss doesn't increase at all when power is increased as there is most definitely increased friction and heat (loss) created due to the greater internal forces exerted on the gears, bearings, etc., but I don't believe it increases by the exact same percentage.

With that in mind, I would fully expect that the drivetrain loss (in HP) of 2018 cars could be less than pre-MCA cars given the updated drivetrain gear. Meaning that I don't think seeing dynos around 410whp (which is one number that has been reported) necessarily means the car makes more than 460 at the crank.

A fellow named "ECOBEAST". That is his youtube channel bought a 2018 401aPP two days ago from a dealer in New Jersey (I think it is Jersey). Check out his channel. He burnt the rubber off of the tires on the first day.\
Still waiting for mine.

R 350 gt Donson said:

Hello I posted this on another thread, My name is Don and I Sold my 2016 GT350R and today I ordered at 2018 Mustang GT Performance Pack LEVEL 2, Black, 401A Premium, w/active valve EXH, MSRP came to $49590.00 ordered it at INVOICE $46,995.68 I order this because I phyical talked to the FORD rep today and he said with the 3.73 rear end they were doing 0-60 times in 3.6 seconds. A youtuber has a video up with dyno of 437 to the rear wheels x .15 (drivetrain loss) = 65.5 + 437 = 502 Hps. Plus the GT 350 size wheels the R springs and rear anti sway bars.....plus the biggest bonus of the New Coyote engine over the FPC. Do not get me wrong I had the R and it was one of the best cars I have ever had..BUT...I personally do not think its smart to turbo it or Supercharge it. However, the Coyote engine you can do all sorts of things to it, i.e Roush etc..For me I drove the 2018 GT PP1 2 days ago and almost bought it it was so fast and LOUD and handel so good I thought I was driving my R again...really it was that good.

I agree .
I don't have an R but own a tech GT 350 as well a couple of really fast GT's-9 second Hellion TT /10.0 KB car that traps 148 mph .

I drove my 3.2 KB car-5.2/GT350 heads/Magnum XL that makes mid 900 rwhp to the dealer where I test drove an 18GT- 301A and A10.
I was blown away by how good it sounded and how fast it was .
I loved the rev matching on downshifts and the accompanying exhaust "burp "

I can only imagine how great it would be with a factory installed Roush Supercharger which won't void new car warranty .

I am already scheming on how to get one but have too much money in my 15 GT's .
I would love to add another mustang to the stable but I would end up in divorce court if I did .

I don't think I can bring myself to trade in the GT 350 except for may be the GT 500 but my 4 year old daily driver ,an Audi S4 is starting to look like fair game(after I get through this winter )

Expecting delivery of 2018 Ruby Red PP/GT on Tuesday the 14th...........

Oly, where did you find the A10? I want to test drive one.

My order came in... 400A, A10, PP, Magneride, active exhaust, sport appearance package, Shaker Pro, navigation, etc. It's exceeded all of my expectations and I'm looking forward to adding a Whipple for half/mile top speed events.
