Did you know if you put a 2003 Ford SVT Lightning Supercharger Pulley on a 2003 Ford Mustang SVT Cobra it will boost the wheel SAE Horsepower from 381 to about 445. Then put some Hoosier Drag Slicks on the Cobra and it will do 11sec. 1/4!! Yippie Skippie!
 
It has 390 stock he says it has 381 at the rear wheels it would lose more than that throuh out the drive train.and it runs a roots type blower.so by changing the pulley you are forcing more air through the engine and i would think you would have to reprogram the computer to make the air fuel mixture right :confused: .

Nah man. The blower sounds great. Gives you the raw muscle feel, when your inside.;)
 
I wish I could get a new Ford Mustang SVT Cobra, but I can’t afford one right now. I found the article in Muscle Mustangs & Fast Fords Magazine’s 2003 Tech Guide Annual Issue. The article is named Fang-tastic, and it was written by Evan J. Smith. For some odd reason Ford has underrated the SAE Crankshaft Horsepower / Torque ratings on the SVT Cobras. In the article the SAE wheel horsepower/torque on the magazine's dynojet ratings are, stock base line: 381.3 hp / 374.8 ft-lbs, and with the stock SVT Lightning pulley: 441.2 hp / 458.4 ft-lbs. The best 1/4-mile run was 11.683 sec at 119.36 Mph. The tires they used were a pair of Mickey Thompson ET Streets in a 26x10.5/16 inch tire size on a pair of 16 inch/ 5 lug take off rims from what looks like a 94 to 98 Mustang GT.

Stupid, people. The Cobra R is a excellent car. It's ready to race. I want to get a GT then put Cobra R mods on it.

I would save like 20,000.:cool:

What's the difference? Excuse my lack of knowledge of Mustangs, mainly because I've only seen one in my life and it was a convertible from about 2000.

The SVT Cobra R is the faster version. More HP, better suspension, among other mods...
 
Ah ok, so they copied off the "Type R" from Honda...heh.

I'm not sure, nor do I portend to be an expert for tuner cars, but I checked the Ford Mustang SVT Cobra's statistics and found it to get 390 horsepower out of a 4.6-litre supercharged V8; from what I can gather on the Internet, the SVT Cobra R gets just 385 - it handles better, but I don't think it's any faster.
 
Well considering the SVT Cobra makes about 410-415 HP Stock, the jump from 415 to 445 is rather reasonable considering you're putting a pulley that would normally belong on a SC for a 5.4 L engine. Anywho, Cobra is faster than the cobra R without a doubt, but around a track the cobra R would win.

Faster on a circuit, yes. The Cobra is all over it on a straight line, though.

390 horsepower 4.6L supercharged V8. If it made more, they'd claim more.

The last Camaro Z28s made 310 hp @ the wheels, when they were rated at 310@ the flywheel. GM claimed 310 at the flywheel to save their asses from Corvette owners.

I don't see Ford doing that - they've got nothing more performance-oriented than Mustang, and it's taken quite a beating recently for poor performance (keep in mind the Standard, Deluxe, and Premium base trims have a 3.8L V6 that puts out just 190-hp). I think Ford would want to claim all the horsepower they can, especially when that's about the only thing that might pull somebody away from something like an Acura CL or Infiniti G35.
 
The only market for Cobra Rs are true racers. They arent overly meant to be driven every single day. Stock I dont think they came with a CD player or anything...maybe a radio, and possibly no air conditioning. The 2003 Cobra is pretty cool...although I wish they could make it have somewhere around that power without the supercharger. But 390HP for around 30-35k bucks...hell yeah.

It does make more, becuase it makes 360hp at the wheels which is too small of a loss when comparing it to the 390 "crank" hp it's listed at, which can only mean it makes hp in the neighborhood of 410+ hp, not only that i'm sure there is some industry standard out there, or some sort of margin they don't wish to cross in order to maintain a large buying market.
 
If you want a racer of the showroom floor, the Cobra is your best bang for the buck. If you have the $$ for a Viper or a Corvette, by all means, buy it. But most people can't afford it and an SVT is a great car for the money.

Actually, that's around 8% driveline loss. That's about right. Based on the 360 rwhp I think 390 hp at the crank is about right.
 
Friction, mostly, and lash in the gears. Just like any mechanical device, efficiency can't make 100%. A manual transmission car should be anywhere from 90%-95% efficient in the driveline; an automatic would tend to be around 90%, maybe dropping as low as 85%.

Why that much for an auto?? BTW can any of you give me info for a 727 torque-flight tranny?

The new 03 SVT Cobra has been tested on Muscle Mustangs & Fast Fords Magazine's Dynojet. They have rated the rwhp of 381.3 SAE HP. The car is pushing well over 390 SAE HP at the crank.

Well hopefully the SVT is a lot faster than the GT. Those things are dogs. I have not seen a fast Mustang on the road yet. I love the looks of them but looks alone aren't what is going to sell me on a car. I guess I'll have to go cruising for one and see how it does.

Yeah, but Chevy tried to go for speed over price with the Camaro and look what happened to it - Ford's doing the right thing by keeping prices very low for the base and GT Mustangs.
