2013 Mustang GT500 MEGA THREAD

[tt335ci03cobra]

Lag wise, it's a non issue. Older tech turbos were laggy especially in the 80's but now a days, there's hardly any lag, just enough time to grab traction in first (~25mph theyll easily have kicked in) then boost from there on. You can integrate a 2-step as well which will build boost like an automatic at the line so you launch with boost.

My 5.4 is plenty fast at 2,000 in 6th. I can get going 160 in about 15 seconds from 6th just by going wot. It pulls kinda hard from 70-90 (think 05 gto in gear at wot), then gets going like a freight from 100-160 with the pull being strongest from 135-160.

I have 3.55 rears and am at 2,000 rpms at 70mph and am about 4300rpms doing 160 in 6th. This is all with about 800whp, but even on 600whp, 6th gear is plenty capable because I can't see 16psi (that I need for 800whp) before 3,000rpms anyway.

Lag is an issue when you go too big or restrict the hot side too much with bad bends and poor planning.

Porsche has small Fran variable vein turbo units that generate 15psi by 2200rpms. Units like those could easily surpass the torque production of a twin screw on a 6.2 or 5.8 from 2,000 to redline because as we all know, the 15psi in an sc setup needs a ton of hp to spin the blower. Probably 10psi from a turbo setup at 2200rpms would be enough to equal a blower at 15psi at the same 2200rpms.


To the guy going on about feminine power or whatever you were trying to say, what the hell? Last I checked sexism started dying in the 90's. Describing pros and cons of things by assigning genders to them is pretty played out. I think, as well as most, that Plato an Aristotle were quite wrong in their views on women. Hell, science has disproven their take on conception and embryos, let's just evolve and quite defaming women already.

Anyways, anybody that thinks turbos are weak should come for a quick ride; wastegates roar, sc's scream. In that sense it could be argued that sc's have a meeker nature, where as turbos have a beastly nature. Most people have never heard open header turbo v8's so I'll upload a video.


Check out this crappy video and listen to open wastegates. I had my e-cutouts open so its easy to tell which car is which. My buddy's 05 gt has a 125 shot and bolt ons. Its a mid 12 car. This was a quick run because a local guy wanted to see me run so I kept it on low boost, spun 2nd, and grabbed 4th as my 3rd gear is missing in action. Street racing is stupid and dangerous. Do not do this at home.

We keep hearing about future cars that would get great milage in the lower rpm's with a cutting edge four cylinder engine, that would have amazing performance with a turbo charger gradating into the rpm curve around 2800rpm. Since turbos can be set to different psi per gear, you could have a system designed for 3 psi in 1st gear, 4 psi in 2nd gear, 5psi in 3rd gear, and 6 psi in 5th, 7psi in 6th..........

WTF are they waiting for?? A 4 wheel drive 4 cylinder car with fully modern traction, launch and magnetic suspension controls with a perfectly intergraded twin turbo charged, gear specific, turbo system, in a much lighter 2500lb modern materials sports car. Where is it??? Erik

I drool at the thought of an AWD American performance car. It seems unlikely though, unfortunately. Don't look now people, but we've gone almost two pages without aimless flaming!

I've wished my Camaro was AWD for a long time..... This thing would be a rocket.

tt335ci03cobra, Why did you go with such short front tires at 25.63 diameter height when your running the large 315/40/18's in back at a 28.03 for your rears??

Do you run your track tires all the time on the street?

How difficult is it for most shops to even understand and properly install the twin turbo kit you have on your cobra?? Thanks, Erik

Thanks for the interest in my build. The fronts are pretty short because I had the 18's and didn't want to get new rims when I bought my last set of tires. (275/35/18's and 315/40/18's). Ideally I want to run 19's front and 20's rear with 275/35/19's and 325/35/20's give or take 5mm front or back to get the right stance but custom 19x9's and 20x11's are pricey so I just ordered tires and figure I'll get a nice set of rims and tires next winter.

Turbo wise, you will always wanna go through a shop that has experience with turbo kits but the honest truth is any body mechanically inclined that is well versed and willing to take some time researching and patiently installs the kit correctly and cautiously can can install a turbo kit.

Mine dual routes routes but it's not too technical if you take your time. The hard part of my build is the 5.4 swap in a chassis that wasn't designed for it. Little things from good clearance to suspension geometry need to be revised and considered. We ended up positioning the motor about 3.5" rear of its traditional location with custom engine mounts and brackets. It helped fitment and avoided a lot of geometry revision. Plus it helped weight distribution and handling of course.

That all said, modern manufacturers could easily stuff production spec twin turbo kits into the engine bays of the modern fleets. The challenger and zl1 have enough room for a quad turbo kit under the hood haha. The mod heads on the 5.8 take up a good amount of space but it's easily doable none the less.

On my kit, we routed my battery to the trunk and put an aluminum coolant tank off the side of my passenger head so my dual in dual out intake could fit.





We placed the bov's in the grill



Here's just a fun pic from a drag strip photo shoot



I think I've hijacked the thread so back on topic, let's hope for some turbo mills on the next gen muscle fleets. Would be so awesome to throw boost controllers, mid pipes, an tunes on those cars and pick up 200hp

Also the factory fronts were 275/40/17's at about 25.5" tall so I kept about the same front height. When I get the 19's on the front, I'll drop the front about 1.5" to keep the same heights off the ground and close up my fronts pretty big wheel tire gap.



I had it lower than this before the 5.4 but I had to install a morosso 7qt oil pan and it sits 1.5" lower than the factory pan so we raised the car to make sure it doesn't get hit. But once I get the 19's on a 26.5" tire, I'll drop the coil overs down a bit in the front to close this gap. It bugs me quite a bit so I'm excited to get new shoes an close it up.

Awesome! That takes a lot of patience and persistence to have that much to added your car. I'm fairly exhausted from doing the changes to my car. I little more weight loss and a Pedders front chassis brace, and I'm done for a while. It never ends, but my car can really carve corners beautifully. and I have had to come down in boost not to be thrown out of corners. Erik

[tt335ci03cobra]

Thanks Eric; handling is definitely a lot of fun. You've got a hot handler o your hands there, congrats on the build!

Try the nitto nt05's when you run out the 555's, they are worth very penny. I've run g force ta's, nt555's, yoko's, etc and these nt05 nittos are awesome. If its more or less a track/weekend car, try the nt01's, they are amazing. But for a street car they are pointless; they have little tread life and are scary in the rain.

Handling wise I have a full front and rear Maximum Motorsports suspension, flsc, Detroit Trutrac, and level 5 stage 2 axels/hubs from dss. The IRS works well once you change the soft parts for delrin and poly.

If you haven't, look into agent 47 and Kenny brown for any additional parts/pieces. Those guys have amazing stuff for the s197.

After going to Supercar Sunday this past weekend, more on that later, I decided to take a drive up Mulholland Highway so I could enjoy the sights and sounds of the awesome machinery that can be found around the area. "The Snake" is what the windiest part of the road has been nicknamed and it is a very popular spot for motorcyclist, sports car drivers and the spot where many commercials are filmed. It is a very windy piece of road which starts at The Rock Store, a very popular hangout spot, and ends at a look out point a few miles ahead. The look out point is always where I choose to hang out as that is the meet up point where many groups of enthusiast seem to like to hangout and have a little pit stop during their canyon runs.

During this outing I spotted a few Ferrari's, a Viper, a whole bunch of Cobras, S2000's, Nissan GTR's, a green mystery machine, a cammed LS1 280Z, Porsche GT3RS 4.0, old British tin, a 56 Chevy and a real 32 Ford...and the list goes on and on. Oh yeah, and I also spotted Jay Leno in his 1915 Hispano Suiza powered by an 18.5L V8. The car is so primitive that even the brakes are cable operated! Leno had a few small issues with the car while on the run, but he was able to quickly fix it and be on his way.

If you ever make it to Supercar Sunday I recommend you add a drive up Mulholland as part of your trip. Just make sure to respect the rules of the road and drive or ride safely. There's been an ever increasing cop presence on the road lately due to people trying to show off and running out of skills on the road.

Those picture make me want to go for a ride.

Well. Never did I think this day would come. But, Ford has officially taken the torch, when it comes to performance, and even family and economical cars. That new CEO really cleaned things up. I guess he meant it, when he said he was going to make sure everything was "first" in it's class. Bravo to them. The V6, and GT were a hit and they got me to visit a Ford dealership. Then the Boss 302 came out. One word - WOW. I couldn't believe all the flawless reviews it was getting. Then I started seeing them at the track, and got a ride from a few track buddies. That car is simply amazing. I still think it is the best all around performance car, offered today. And now the GT500. I am at a loss for words.

What's next Ford?!
