    my 2017 cali special A6 with 3.55's a catback and Ford Perf Pack 2 has gone 12.6 @ 113 @ 4060lbs so I would say the 18 is faster

    Guys there is a new youtube video of a new gt with basic boltons without intake manifold modification running 11.0X I don’t remember what the exact time was. With IM’s and full bolt ons the new 10 speeds should dip in 10’s. That’s pretty amazing.

    If they are both running 93 octane, the 18 GT all day. If the "tune only" 15-17 can run an E85 tune, it may keep it close, but my money would still be on the 18. The stonger motor and gearing advantage makes for a quick stock car with the new GTs.

    I'd say it'd be close, but depends on what tune is used.

    If you use Ford Power Pack numbers (for sake of warranty) they claim +13 peak hp for Pack 1 giving the '17 GT 448 hp. Power Pack 2 makes +21 peak hp for 456 hp.

    So it seems PP 2 would make it a close match.

    Ditto!

    Decades working as a Professional Firefighter/EMT, and I'm pretty tired of hearing it myself. :thumbsup:

    I've read that the 3:15/Auto is quicker than the 3:55 in the 1/4. At least as it applies to the 15-17.

    My old automatic 2016 GT with kooks catless LTH's, pmas intake, awe exhaust and lund 93 oct tune doesn't feel as fast as my new stock 2018 gt with the 10 speed transmission.

    Id say that a tuned 15-17 would be a drivers race with the stock 18 in the 1/4. I’ve seen em go 12.1 with good DA. I’d expect similar times out of your average joe in an 18. The 18 will have a sizable advantage in trap speed. So any roll races the 18 will pull away.

    I did a 60mph roll with a 630+rwhp '16 GT PP with Roush blower, long tubes, full exhaust, etc the other night. He was about 5 cars out when we shut them down (130mph?). It shocked everyone it wasn't cruise ship lengths including me.

    Might be late but I've spoken about this before, cousin has a fully loaded 18 PP auto stock and I have the 17 GT with Lund tune and michellins and I have a quicker 0-60 time and I always beat him from rolls. Will try and find the video

    Not sure how much this will help but my buddy and I got lost in Mexico. My mods: intake/e85. His (2017): intake, long tubes, tune, exhaust, etc...

    If the 17 auto only has a tune I would put my money on the stock 10r80.

    The 10R80 seems to be worth about .4 sec in the 1/4th. Between HP and Transmission, you need to find .6-.7 secs worth of mods to be even.

    Splitting hairs. Especially with a convertible with the extra weight and lack of chassis stiffening and it's effects on hard launches. The car differences are mostly features and the shared mustang/camaro tranny.
    Somedays you just want a convertible and some days you don't. Tough choices.
    The big question is whether one prefers the GT350/15-17 Mustang or the 18-19 Euro style Mustang. Either way, you win.

    A e85 tuned 18 plus a10 run pretty strong (for n/a) from a roll. Not a lot of weak spots gearing wise outside lower gear traction. Once they wind up they go.

    in my opinion a tune only 17 GT auto doesn't stand much of a chance against a 2018 PP A10, I dont care who's tune it is.

    This. Sorry, but the 15-17 is stretched to its 435 rating, the 18 underrated at 460. Unless you truly believe large capacity, almost 10% more compression, GT350 like manifold flow, etc... all add up to only 25hp.
