2015 Mustang GT breaks into the 11's in the 1/4 mile!




It went 11.77 seconds to be exact and past the traps at 116 mph and that's with minor modifications. The modifications were courtesy of the folks at Ford Racing. They recently got a hold of three 2015 Mustangs, one with the 2.3L EcoBoost engine making 310 hp and two GT's with the 5.0L V8 making 435 hp.




The power modifications are minor for two of the three Mustangs. The 2.3 EcoBoost gets a "Prototype Off-Road Exhaust" which most likely means there are no catalytic converters or "cats", a more free flowing exhaust and a tune. One of the GT's gets the same off-road exhaust treatment and a tune plus "ARH Cobra Jet Long Tube Headers". In the video, they say they did "a few changes to the air intake system but basically these are close to what any consumer can buy" so they may have included a K&N drop-in filter which FRPP Performance Packs for the 2014 Mustang GT included or an aftermarket CAI with a cone style filter.

The final GT gets the full treatment which includes all the above plus a Ford Racing Roush supercharger and obviously a new intake to accommodate the supercharger. It is unclear what the boost psi level is for the supercharged GT and what the tune raises the EcoBoost psi to but the 1/4 mile numbers are great. Additional suspension parts and drag slicks help the drop the time.

The passenger and rear seats are removed and the driver seat is replaced with a race seat but that seems to be the extent of it for weight savings, probably to substitute for the roll cage and testing equipment if any are fixed to the car. If you pause at 2:18, you'll see one of the the mounting points for the front passenger seat surrounded by black (the carpet). I know the front seats on the S197 Mustangs weigh about 60 lb. each (mine weighed 57 lb. with the frame). According to American Muscle, a rear seat delete kit on the S197 Mustang saves "up to 30 lb."  Between the race seat and removed passenger and rear seats, total savings should be under 120 lb. The roll cage probably offsets most of that if not all so overall difference, positive or negative, compared to a stock interior is probably negligible.

If these parts are available through Ford Racing like power packs for the S197 and maintain warranty if installed by the dealer, it will make a lot of people happy. Watch the video above to see the new Mustangs going at it or scroll below to see a list of modifications and 1/4 mile numbers although no dyno numbers are listed.

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track loads.…

Stock Suspension S197 Mustang With Square 305/30/19's

If you've had any doubts about whether or not they will fit, fear not! You absolutely can run square 305/30/19's. I had a lot of doubts before pulling the trigger, even more so when the wheels where on the car. The tires do poke out a bit and I figured rubbing is all but guaranteed at full compression but I couldn't be happier I trusted APEX and those on here who have run it.

Here's what you need:

1. Camber plates: I have MM C/C plates and they are maxed out at -2.3 deg with the stock struts. I have been running them for years with many track days without issue.

2. 1"/25 mm spacer: I have Motorsport-tech 1" spacers and they look like high quality units. There is maybe a 1/4 inch clearance in the back so you can't go any narrower than 25 mm. http://www.motorsport-tech.com/adaptec/car/ford_s and you want Design 2.


3. Elongated studs: your best bet is to get the FPP hubs with elongated studs instead of reusing the old one. Bearings are consumables anyway so…

Michelin PSS vs Firestone Indy 500 - Track Review

A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity.

Grip is noticeably lowe…
