Well, with the dual 8" chrome stacks and air horns I'm pulling down to 190 at the crank...

Just playin. With a simple pully, cat back and basic bolt ons (CAI, etc) it was right at an honest 450hp/450tq to the wheels, and spiked up to as much as 470 with good air (uncorrected dyno numbers). That netted me a 12.57 @ 118 with 4:10 gears (video link in sig).

I smoked the original motor doing top speed runs and 90+ mph drifting on El Mirage Dry Lake in the middle of summer on a weak batt and bad Alt. Hiccup at a traction limited 168 mph smoked two pistons. Video available on request, haha.

The rebuild was supposed to be mild... just minor port-matching of the stock heads, then porting the stock Eaton Blower and lower intake manifold. Added some better rod bolts and crank bearings, balanced things out very nicely and such netted me right at 500 hp / 500 tq to the wheels uncorrected. That with what is considered low boost... all the porting dropped my boost to a tick below 12 psi. I then added more mods to supply the needed fuel and it is right up arond 520. We then strayed away from the factory gun metal gray and went with a Kenne Bell looking satin black on the blower and old school Ford Grabber Blue paint scheme on the valve covers. Some appreciate it, some dont. It is amazingly mild mannered. The wife can drive it (with trac-control on LOL) and it still can see daily driver duty and gets 21 mpg if driven nicely.

It's built to take 14 psi or more, which would put me in the mid-500's on crappy CA 91 octane. The internals can take it, but I am actually enjoying the mild-tune, as it generates lower intake temps and is better suited to extended WOT usage that I see in my Open Track running. If I were a strict drag car,or purely running it on the street where it would only see short bursts of WOT, or the very brief pull through a gear, I would add a 2lb lower pulley and do it for the big numbers. Big Dyno number can be sort of addicting.

But, I am running 100% stock cooling for both the intercooler and engine fluids, other than running a straight "water-wetter" type of fluid.

I actually had to go back to the stock 3:55's as at these torque levels, traction is the issue (also stock suspension, brakes, etc). Unless you are running premium 315 Drag Radials all the time, it just goes up in tire smoke to be honest. Even then, you have to feather it from a stop.

Currently I am running 335 Michellin Pilots out back as used on early Vipers. A hard back shift into third on the freeway can snap them loose and have them spinning wildly up over 65 mph.

But, it's been a great do it all car. I used to enjoy sampling cars, and would jump car to car every 18 to 24 months. I've had this one longer than anything I can remember. Guess it has something to do with the fact that it's paid for, reg. is cheap(er) and to get the same level of performance, it would cost me $80k +.

Though I admit, I am getting older and really get tempted by the new stuff coming out. An amazing Shelby GT500KR was at a local dealer, and I lusted after it. Too costly. One day I may have to just back down from the performance and get a nice Challenger loaded with all the bells and whistles. Soft, and slow. But it has the great retro looks and makes the right noises. Hell, I may even get an automatic and just enjoy the ride.

2004 SVT Cobra, the last real mustang My 04 had very similar numbers with pulley, cai, and tune. 455 hp, 458 tq. I miss the pure raw power of that car. It wasn't comfortable to drive, didn't handle well, had an awful interior, but dam it was fun

Love to see the videos..
Yea drifting can send temps sky high.. going sideways on throttle boosting and not much air going over radiator and intercooler or heat excharger..

My Cobra had almost 100k on it for miles and was thoroughly worn out. I was faced with dumping maybe 10k into it which I would never get back or selling it and moving on. If it wasn't for the high mileage I'd probably still have the car. The SS is a differant car, it does everything well but it doesn't have the attitude the Cobra had.

[ffrcobra_65]

I used to think the terminator cobras were the last of the snorting mustangs until I rode in a friends 2010 GT500. I ended up getting a 2011. Stock for stock, the terminator is exterminated in every aspect.

but if I race someone in a GT500 that really knows how to drive and he beats me, is it because the GT500 is a better car or because he is a better driver?

Will that make me like my car less?

In the end, the better car is the one that you personally think is better.

You are adding way too much common sense into this conversation, please stop.

Very nice setup.
Is 12psi. considered low boost in the Mustang world if so what's considered big dyno numbers for the ford engine?
What's the compression ration of the engine, must be very low?
Also, you using any safety adders like meth?
Reason I ask is it's estimated I'll be pushing over 650rwhp. with only 6psi. with a ProCharger could go with 10psi., but I think that would be more risk with less benefit so what's the point.
At 12+ psi. safely I'd have to stroke the engine to change displacement to 416ci or more, and lower compression to like 9:1, and get top notch forged internals. With 12+psi. numbers would be insane, and probably limited on pump gas, whch I think would be un-controllable on stock rear-end and tires.
Dear OP, don't blast me for the mod talk, I didn't start it. Cool?

i think were cool. good questions. my gt500 runs 9lbs boost stock - not sure if that is kinda standard for s/c mustangs or not.
i started this one - but that cobra is very awesome!

holy crap - youve been through a little with this one. very nice - i like how it can still be a dd. nice explanation of what you did (and why) to the termy.

ive always looked at the 03/04 cobras as the brawn and violence - while the gt500s are a more refined monster - both are good depending on what the driver is looking for.
