91 Formula vs Porsche Carrera S??

This may seem stupid from what Ive heard about these cars, but my sister sold her Mustang Cobra and her husband bought her a brand new Carrera S (yes , they are doing pretty good). I visited them in California recently and got to drive it. My Brother in law (major Ford guy) says it has 600 HP. Honestly I wasn't THAT impressed with the thing off the line. It is a 6 speed and I almost had to pop the clutch to get the tires to spin a bit. I couldn't really wind it up because of residential streets.

Now I know this thing would kill me in a road race, hell my front tires would probably roll off the rims if I went arouond a turn to fast, but I think I could take it in a drag race. Ive run 12.78 at 104.75mph. Im sure I could get it in a 1/8 mile, but maybe by the 1/4 it may fly by me. I'll never be able to actually race her since I live in TExas. For $120,000 I expected more, I guess I would need to take it to a road race track.

Re: 91 Formula vs Porsche Carrera S??

355 hp and less than 3200 lbs, so basically its almost like a C5 vette.

i think you'd lose from a roll, and on the top end of the track from a dig on street tires lol

on your radials you'll outlaunch and they have to drive hard to match a 12 second slip on street tires

Everyone always drives a 500 HP car till it gets to the dyno.

Re: 91 Formula vs Porsche Carrera S??

I think a lot of people tend to overestimate their horsepower ratings on their cars and a lot of people dont realize that even if the motor makes say 300 horse, thats not the power at the rear wheels.

Anyway, I hope that anyone on here that might end up racing a porsche that they kick its a$$, i cant stand porsches

Re: 91 Formula vs Porsche Carrera S??

driven alot of porsches, they all have the same funny smelling interior, and i'm not particularly impressed by carrera's, start talking bout a turbo 4, okay. they are just built for a different purpose, a true grand tourer.

hope the popping the clutch to get the tires to spin isn't trying to reference how much that thing has. spinning the tires doesn't mean power it just means loss of traction. if you don't believe me I could of shown you a stock 74 maverick that could white smoke them as good as anything out there and my 68hp honda can even get a good spin going out of t he tires. both have no power but both also have no grip

that doesn't mean a whole lot though. I have seen cars with just a tad more then that to the wheels break into the 12's

Exactly. Big tires with 500lbs of engine sitting right on top means they hook up like nobodys business. It's the 911s traction that gives it the phenomenal 0-60 and 1/4 mile times that it's always had despite always having less power than its competitors. Another factor is the lower drivetrain losses of the rear engine layout, but the bulk of it is in the traction.

Re: 91 Formula vs Porsche Carrera S??

yea but having all that weight out back gives them funny handling, and you pay for that great traction off the line with horrible traction braking into a turn... i play far too much gran turismo 4... fr or awd, way to go. 30000 evo''s spank porsches dollar for dollar. an evo mr is a match or more for the cheaper porsches

Well then, don't brake in turns. The rear engine layout leads to quirks, but in the hands of a capable driver it's no handicap, the 911's racing history proves that rather amply.

Actually, mid-engine RWD is ideal.

You just nailed my car. 258 rwhp, full weight on 18" Street tires... went 12.95 @ 106! Hell 250 rwhp in the right chassis will go low 12s in my opinion!

you do play GT4 too much. if you know how to setup the car MR is about the best platform you can get more often then not. sure it's the least forgiving, doesn't give you a warning before it's too late, better not screw up platform. at the same time though it does give some of the best all around grip that you can get.

AWD is a comprimise gone bad I would say. sure it works and works well for dirt but on pavement AWD isn't that great compared to a rear wheel drive platform.

Re: 91 Formula vs Porsche Carrera S??

for one, porsche is not mr, mr is terrific, porsche is rr, as in rear engine rear wheel., fr has the best braking, it's just the way the weight distribution works out, physics. weight in the front means the a** is light in braking, makes the a** stable as long as brake bias isn't too high to the rear. rr means weight is out back, doesn't work as well. these are facts, as much as gt4 is a game it is also a simulator.

awd is proven, some of the fastest cars in the world ar mr awd, or awd. there's a reason people beg for skyline's. there's also a reason a fairly cheap evolution can launch full on the rev limiter with a clutch drop and not spin the street tires they drove in on, show me an fr that can do that with the power the evo has.

mr cars are a comprmise between fr and rr, weight is far enough forward to not mess up your braking, but far enough out back to stomp the tires into the pavement on takeoff. you pay for it mid turn, if you let off you get a type of oversteer that is specific to mr, but punch the throttle and you can pull it back straight.mr cars are nsx's for example, motor ahead of rear axle, porsche is on top of and behind rear axle. makes the car compact and cheaper but less effective overall.

Re: 91 Formula vs Porsche Carrera S??

i should have fleshed out my statement on RR's braking, think about braking into a corner, now if you do it by the book, brake, then release and turn, you're golden, but what if you come in too hot? what if you have to brake while turning? now you have all your weight sitting high(Since you were on the brakes hard) and in the rear of the car(since it's RR). you won't understeer, because it's RR, the front tires aren't overloaded, however your rears are tremedously over loaded as RR's have higher rear brake bias and more weight on the A**. unless you can drift an rr, you're probably going to spin.every layout can go fast with the right line but rr's are at a big disadvantage. it's just the opposite of the problem that FF's have, which is understeer.

that same weight that gives awesome takeoff traction will inevitably subtract the lead you gained at the entrance of the first corner. FR is middle of the road, pretty good takeoff, the best braking,power efficient,forgiving and flexible. mr is like an elite drivers choice, awesome takeoff, braking that nearly equals fr's and makes up for it mid turn, much better coming out of a turn then fr, but unforgiing and unflexible, it can't adapt to a changing situation or inexperienced driver. it's why mr2's had a reputation of being dangerous back in the early/mid 90's, racecar handling but unforgiving of beginners.
