Hello all, first post on s2ki. I am just wondering, has there been (or will ever.?) an s2k that broke into 12 seconds 1/4m with NA setup yet? I personally could not find any evidence of such creature and "12 second" could not be used for search on this forum....

The reason why I asked is because there are FF all-motor Hondas out there (street legal and otherwise) that can run 12 seconds or faster down the strip, and here I am wondering, with all the drivetrain advantage and wonderful F20C, I have yet to see an S2k break into 12s......

If there are s2ks running 12s already then I prob missed it, but I would appreciate any reply from credible source!!

Thanks all for reading.

 

Mandatory Post: The s2k is not I repeat not a drag car. It was never designed for it, and it does not excel at it in stock form.

The most probable way to get a 12 sec car is to remove massive wieght. The S2000 is highly tuned from the factory and doesn't gain much in mods. Even Spoon racing motors top out at around 300hp IIRC. Dropping pounds = cheaper and easier to gain seconds than engine mods.

The reason FF N/A Honda's can run 12 seconds is because they're generally hatchback civics, CRX's, etc. In other words, they're small, which means they're light, ranging from 1900-2200lb's (guesstimate). 200 Horsepower pushing 2000 lb's is going to be faster than 240 hp pushing 2800 lb's...

As for drivetrain advantages, to launch well requires ~4.5-5k (or higher) rpm clutch drop. With a turbo, lower it to ~3.5-4.5k rpm's. Eventually, anyone competitively launching with a stock differential will blow it out.

 

Welcome aboard though.

 

I haven't seen anyone post about a 12 second all-motor S2000. I'm certain it could be done, but I don't think it would be financially feasible. It would be much cheaper/easier to slap on a turbo/supercharger, tune it properly, and swap in some gears. For under 10 grand you could hit 12s in that car. Might wanna save some money for replacement diffs, though.

To hit 12s in an NA S2000, you're going to pretty much have to re-build the motor from the ground up. Rods, pistons, valves, cams, headwork, etc. Then add gears, exhaust, header, etc... and you're looking at closer to 20K.

So, I think there just hasn't been anybody motivated enough to go through the trouble and expense to do it. If you want to be the pioneer, I'm sure everyone would love to follow your story. There was a guy on here that went by Hams2000 that was doing an engine build-up, but I haven't heard anything about it in months. I think either the bank ran dry and he couldn't complete the project, or the thing just didn't perform as expected, so he vanished into thin air. Maybe someone else knows the details.

Anyway... to reiterate what's already been said... the S2000 wasn't designed for drag racing, and you may be disappointed if you focus on building a S2000 into a drag racer. But it's your money, and with enough money almost anything is possible.

 

Some fundamental differences between a Civic and an S2000.

The Civic has it's engine and drive wheels at the front. The drive train is almost non-existant. The S2000 has the engine at the front and drive wheels at the rear. The size of the drive train adds significant weight. There are a number of advantages to a FR set up but very few of them mean a thing in a race that is 400M long in a straight line and lasts less than 15 secs.

Also, being a convertible the S2000 doesn't use the most efficient structure for rigidity (twist a shoe box with and without a lid on and you'll know the difference). It makes up for this inefficiency with a very rigid (and heavy) X-bone chassis. The extra weight is worth it for the improvement in handling. Once again, this comes to zip in a 400m race.

If you want a great performing fun convertible buy and S2000. If you want a drag car look elsewhere. Drag racing is racing for ADD sufferers IMNSHO.

 

Hey thanks all for replying lol! Actually I am not disappointed, and from what I understand S2000s are more of circuit racing sports cars rather than a dragsters. I just want to hear some comments and insights from this board. Personally I'd approach this 12 sec "barrier" with massive weight reduction and racing engine mod, and I too, think it's possible with all motor set up.
From the feed back though I get a feeling that this is not a very feasible financially nor practical (blown diff?? ) for about 99.9% of S2k community, but I would like to see one 12sec S2k nonetheless!
Finally, as for the drivetrain layout advantages, I was referring to weight transfer for launch traction and less roll resistance with less psi, but those are probably more applicable to NHRA dragsters than modified S2000s. I realize the FR setup also eats up more HP from the flywheel to rear tires, but I think carbon driveshaft might help a little. Also changing the diff with a more robust one/proper gearing might help too.
I am not anywhere close to be technically nor financially able to build an S2000 that runs 12secs, but the idea just intrigues me. The FF Hondas were not designed to be dragsters either but some got them to run 12s or less already. I realized S2k is heavier but I think it's possible. Now all we need is proof.....

 

I have considerable mods on my S2000, and just make 248rwhp. Life's tough, I tell ya.

 

I'd have to tow my S2K behind my Cobra.
