Blake,
Glad to see you're still around despite not having an s2000 anymore. Here's a question, stock for stock, you say the RX-7, but what about a s2000 with 4.77, CAI, exhaust? There's a red RX-7 that I see around sometimes. I've gotten a few "revs" at lights, but haven't taken him up on yet.

If he's stock, you shouldn't have a problem. I'd assume you could almost pull low 13's easy with that setup.
But if he's even got a full exhaust, it might not be close. He might be able to get you high end even if he's stock though.

infinite, welcome to the club, even if you do like to eat parking brakes.

Loose or walked?

CAI/exhaust/ECU will not be worth more than 25 hp on an S2K. I don't think you would get beat down or anything by an FD with a downpipe, but I think BEST case it would be an even race.
However if you take those same mods and apply them to both cars, the FD is going to seriously walk an S2k by car lengths.
Rotary engines respond extremely well to exhaust modifications.
Turbo cars in general response extremely well to exhaust modifications.
Put 2+2 together + ECU for increased boost and fuel management.
One of the things I love about the S2k is that it can produce so much power for it's 2.0L engine - yet at the same time one of the things I hate is that the envelope for increased hp without forced induction is very small. Even after utilizing a forced induction method, one isnt going to be running large amounts of *reliable* boost on the f20c even after addressing it's open-deck design w/ sleeves, and low-comp pistons.
Sure you can make it do 20 psi and put out 450 hp, I just cannot seeing it lasting that long, honestly.
That being said, the tuning potential of the f20c has probably not been fully realized yet.

clayne,
I wasn't flaming the rX-7... I really like the car. I just wanted to see how I would measure up.
The only thing I disagre with is your statement about tuning potential. The fact that you can't reliably put 20bls of boost on the car, to me, says the cars potential was pretty well maximized by the factory. Also, the weak link isn't the engine, but rather the differential, axles, etc. That is what's going to give with FI.
We'll just have to see what happens. The next time he revs me, I am gonna run with him. While I don't underestimate the rx-7, I think he'll me underestimating me. BTW, I don't think you really took the lower gearing into account. The 4.77 give the car substantial more pull in the low to mid range, where it was previously lacking. Given that, I think the rx-7 will think that he'll get the jump on me.... but I don't think/hope that I get walked.
Later and thanks for the input...
Blake, care to comment since you've had both cars and know about the s2000 with gears?

Have you ever run at the track at all? Do any members on here have experience with what an S2000 with 4.77's can do? Honestly, I've never seen any comparisons on any cars about what they can do with lower gearing.
Now, as I said, if he's stock, then I think you can do it. 4.77's are pretty damn low. And this considering I originally came from owning a truck and being into offroading. Even then 4.44's and that range are considered pretty low. I still won't say you'll win or lose, since I've never heard how this car runs with the shorter gears. But I think most good drivers can get a stock RX7 into the 13.6 range, maybe a bit lower.
Of course, as Clayne mentioned, a good intake and full exhaust (which if he has that and no kind of engine management, god help his engine), he should be able to break into the 12's. But I think most people would be surprised at how many stock or near stock (just cat-back) RX7s there are running around.
Regardless, I think it'd be a good race, and will love to hear the outcome. Generally, when there's this much indecision about who might win, its going to be a good race.
If you can, talk to him and find out what he has, and run him a couple of times just to help back up what happens.
