06 SC saleen 435HP, 07 shelby GT500 500HP, but possibly a few hundred pounds heavier. 0-60, and 1/4 mile times. Should be close, what do you guys think, stock for stock, same driver.
rans00vert said:Ricks, apparently you are not very familiar with the new 05-06 saleens. Twin screw blower, runs on only 4-5lbs of boost and avg rear wheel horsepower has been at 390-410 at the rear wheels. Leave it in the dust? A 300 horsepower GT does a claimed 4.9 to 60, vs a claimed 4.5 to 60 with 500 horsepower. The new shelby apparently doesnt even leave a 300 horse GT in the dust to at least 60. Slap a saleen blower on the GT and it beats 4.5 to 60. I disagree with your opinion, especially since I have one. My car outran in the quarter mile my friends 460hp 2002 viper GTS, and both of our cars are stock. The car is no slouch.

rans00vert said:0-60 means something if you drive on the street. Not everybody takes there mustangs to the track. My original question was what was your thoughts 0-60 and, I said 1/4 mile. I have seen dynos of saleens posted on various mustang sites. I do not have one to post. Does that mean I am BSing? No. Are you saying the new SC saleens do not have that kind of power? Evan Smith drove a 2005 SC saleen with 400hp to 12.5 at 115, in MM&FF last year. The new one is 435hp. It should do a little better. That is right in the ballpark with the "claimed" times of the GT500.
As far as my friend and his viper. He races SCCA in the viper, and is a very very good straight line driver.
RICKS said:Not much difference in weight, not enough to nullify the HUGE horsepower disparity.. Not to mention the fact that Saleen has always historically published horsepower figures that seemingly never jive with actual performance tests.
I'd bet that the GT500 leaves the Saleen in the dust.
NK06Roush said:How is over 500lbs not a big difference in weight? 06 GT w/supercharger =3500. GT500 close to 4000lbs The new c6 corvette which I know is only 3100-3200lbs has a whole 100 hp less than the new GT500 but its still faster than it in 1/4mile. You would think a 500 hp car would be quicker buts its a heavy s.o.b. Don't get me wrong...I would die for a new Shelby and I do think it would be faster than a s/c saleen in the 1/4mile but only by very slightly given equal drivers. Basically in this situation what it comes down to is if the gt500's extra 65hp (given the hp figures for both cars are acurate) is enough to overcome the 500lbs of extra weight it carries. Forget about the convertable tho. 4200lbs....I'v seen SUV's lighter than that. One other thing to keep in consideration is the aftermarket mods and their effect on the new shelby. While the saleen maxes out with a safe 435 hp (and I mean without forging internals or any serious engine work) the GT500 may be capable of making close to 600hp with a few minor boltons and a smaller pulley swap. While the saleen can swap in a smaller pulley it runs the risk of really blowing the engine. The gt500 can have much higher hp potential without serious risk of engine damage. Then its weight will start to be less of a factor. Stock tho - I think its too heavy. Just my .02
RICKS said:O.K., now we're playing with some slightly sloppy data.
* Curb weight of a stock 2006 GT (no blower) is 3483-3518, assuming it's a manual, ranging due to options. Adding the blower kit depends on the kit, intercooler or none, etc.. Alot of options there. But....who cares, this thread's premise was a SC Saleen vs. GT500. Everybody knows that you can aftermarket-add-on a stock GT to move as fast or faster than the new GT500 for less money, you just lose your warranty, and take your chances with driveability and durability. It's always been a bit pointless to compare factory iron with shadetree builds.
* 2006 Saleen S281-SC, Saleen claims an "estimated" 3550 lbs. I'm having a tough time buying that, if you extrapolate the stock GT's weight, figure the Saleen is fully optioned, and then add that hefty/fancy center-exit with electrically-activated-dumps exhaust system, all the cladding, the extra bodywork on the tail, the supercharger with 2-stage water/air intercooler, and those HUGE 20-inch wheels with larger rubber, it all adds weight. And on my calculator, it would have to add up to more than 32 pounds, which would have to be the figure if the 3550 claim were correct.
* 2007 GT500 curb weight is 3920 lbs. If you're going to round-up, round everybody up 80 pounds to make it fair. Bottom line, there's not "500 pounds" separating the GT500 and the Saleen S281-SC. No way.. My best educated guess, given the aforementioned facts, is a roughly 300-lbs. So the question is, does the GT500 have enough extra juice to overcome the equivalant of a fat passenger?? I think it probably does.
* 2006 C6 coupe curb weight begins at 3179 lbs, but there's an AWFUL lot of options on those cars that bump up the weight. Most magazine test cars chime in at 3270-3300 pounds. 1/4 times at all the mags for Z51-equipped cars (better gearing) are in the 12.5-12.8 range at 113-114 mph. They are just a whisker quicker, but lower mph, and that's with better aerodynamics. So how do they get the quickness over the GT500? Better front-rear weight bias puts more weight over the rear tires, better transfer at launch, better 60-foot times. Simple, it's drag-racing 101.
* Motor Trend ran almost identical 12.7 @ 116 mph 1/4-mile runs in two different GT500's, at two different venues. Supposedly (I haven't read the article), Evan Smith ran a 12.25 at 117+ for whatever that might mean to anybody (his times always seem to be beans vs. franks, they've always got some tweaking involved..). In any case, Motor Trend's times show that the GT500 is pretty-much on-par with the C6, and actually a bit stronger pulling once the launch and 1-2 shift are out of the way. Not bad for an extra 650-odd pounds of luggage vs. the Vette.
At least we both agree that the GT500 will still likely put a nose on the almost-as-porky S281-SC. And you made a brilliant point that the GT500's short-block is battle-ready for easy-breezy performance upgrades, whereas the Saleen's internals limit your ability to reach deeper into the boost.
I just wanted to make the arguments accurate.
RandyB said:Good thread and some really outstanding posts by RICKS. I'm wondering a lot of the same things since I have a very lightly optioned '06 GT (base CD player - not the 500, no side airbags, 5-spd manual, leather, IUP) and I'm in the process of installing a Roushcharger kit along with some GT500 intercooling system goodies. I'm hoping to have a car that is close to Saleen's approximation of 3550 lbs when I'm done, but will most likely go over that even though the Roush system has to weigh less than the larger Saleen blower. I'll also be making a little less power though, but the ultra-OE looking and fitting Roush kit was too good to pass on. My target for peformance is somewhere between a stock '03/'04 Cobra and a C5 Z06/base C6 Z51. I have KDW G-force 295/35-19s on the rear, and hopefully they will do ok in the traction department. I was finally able to get part numbers for the GT500 parts I needed today and ordered them, so it shouldn't be too much longer until I'm running. Here are a few pics:QUOTE]
Hey let me know how the roushcharger installation goes. I'm curious to see how you like it. I bring my in to the ford dealer in 3 weeks to get mine done. Jack Roush is also going to be there signing cars one day that week also, so when I pick up my Roush it will be supercharged and signed by jack. Can't wait. I'm also having the ford racing boost and fuel pressure guages installed on the Apiller. Anyway tho, goodluck with the rest of the install.
