it'd be ugly and slower than a 951... 2 strikes there...

The stock hardtop does not help the Aero much but the spoon or one of the spoon knockoffs would help.
A stock S2000 is real slow from 100-120 and 120-150 takes a looooooong time and a lot of open space.

i love that diagram about VTEC...lol

someone put a roots-type on the F20C and give it some torque

Its ALWAYS the Audis messing with me for some reason.
I think its because they are usually my age...chronologically, anyway.
There is a guy with an RS6 around me who NEVER gives up - one night I had to spank him 3 or 4 times.

Default I've got a supercharged S2000 running 10psi

Hey...I don't think a 2.0L NA motor is a fair fight against any FI motor'd car. But, I've got a supercharged S2000 running 10psi and I'll have a go at ya. We'll have to meet in the middle, though...hehe...I live in Salt Lake City. Maybe you'd like to see Miller Motorsports Park?

S2000 2700 951 2900 (Est)
S2000 weights 93% as much as a 951.
Add 1000lbs of drag (Note! A S2000 would Produce 1000lbs of drag at like 200mph but I am just showing this to show the difference)
S2000 3700 951 3900
S2000 now weights 95% as much as a 951.

As far as gearing I guess it depends on the S2000 between the 2.2L and 2.0L due to red line.
Look, top speed is proportional to the cube-root of HORSEPOWER. If it's a diesel making 240 HP (because it makes 480 ft lbs at 2600) or an F20C making 240 HP (because it makes 160 ft lbs at 7800 (I'm just using rough numbers for this example)), it doesn't matter. Top speed will be the same, assuming that both engines are properly geared.

What matters during acceleration is area under HORSEPOWER curve. Since it has low HORSEPOWER at low RPM's, the S2000 is slow under a rolling start condition. Of course, this problem is eliminated in a standing start by doing a high RPM clutch drop (I use 5K to 6K, depending on conditions).

i was chasing a new 997 s cab and the 951 was keeping up pretty good for the 2 Corners we took at speed I think he would of had me on the straight but it was a nice to know my 20 year old car still had it with the newer Porsche technology.............................

RS6's only have a piffling 450HP, 570 if its a 2008 model.

Either way your car which is considerably lighter should destroyyyyy

Now Now Gents ... Lets not get carried away on this thread Remember the "Code of Conduct"


Please delete all the posts/threads like "I beat a (insert your favorite car here) on the Public Roads, endangering my life - and all around me as I drove like an idiot, doing 100+ MPH on a public road......

All the "I beat some idiot in a (insert your favorite car here) in a road race..." has no place here.

If you want to "drive fast" - do it on the track - and get instruction for doing it "on the track". In short - it will save your car - and probably your life. Not to mention the lives of those who may be killed by you.

If you do take it to the track - you'll be a better driver for it.

How would I know?

I take it to the track - and instruct instructors, before they get in a car with you...

So - PLEASE NO MORE STREET RACING THREADS. Take those to the Honda Forum.

As an FYI - This is *not* a Honda Forum.

Have a wonderful 2007...

John D.





BTW Yes this is Jap Scrap heaven here in Ireland and everyone wants a slice of my 944 Turbo.....!

There I was minding my own business when a tosspot in a VTi Civic starts revving and snorting. I ignore him and he keeps this up for 2 miles. I slow up he passes on the revlimiter.... He goes on and I forget about it.... Around the next corner there is blue lights everywhere... Yes you guessed right.... The Cops had him pulled in and he was snared.... I just give him a smile as I passed by......

Proved this to myself and the dude in his S2K the other day...while driving our simulators of course

I agree on point 1, the S2000 does suffer from poor aerodynamics at higher speed. In point 2, what difference does the lack of torque make? It's hp that matters, and presumably one would be shifting at redline. Does the gearing advantage exist? And if so, why does it end at high speed? Off the top of my head, shift points in the S2000 are approximately:
1-2: ~42
2-3: ~63
3-4: ~90
4-5: ~120
5-6: ?

It's HP that matters? So Torque means nothing?

The S2000 has to rev to 7,000 rpms to get out of it's own way.

That's also why my 2002 Crown Victoria casually blows away my 2006 Pontiac Solstice (or an S2000 for that matter) to 30mph.

Honestly though, and I mean this in a very subjective way... Honda still has a long way to go. Although they've had some sporty cars in the past with the CRX Si, it's really only been 10-12 years since they've really started making an effort to produce cars with some power. Even with professional racing. I can't remember a single Formula-1 race in the past 5 years where at least one of the Honda motors didn't blow up. Need clarification? Just ask Rubens Baricchelo.

The S2000 is a great motor, but the S2000 is still nothing more than a Mazda Miata competitor. If they want the S2000 to compete with cars like the Porsche Boxster, the Z4, and now the Solstice / SKY with the Turbo motor... they're going to need to step up their game. In all honesty, this is a rather silly thread. I don't know anyone who would rather have an S2000 over a Porsche 944 Turbo-S. I mean, unless fuel economy and reliability was all that you were concerned with.

It has nothing to do with ragtop vs hardtop its just the S2000 has a very vertical windscreen along with poor shape of the roofline.

Thats the worst example ever also how is hp to the 1/3 power have anything to do with topspeed. Thats basicly stating that HP is proportional to topspeed (A true statement). Now, I agree with "power under the curve" but the 951 has more under the curve. Its one of the reasons the top speed of the 951S is like 10mph higher then a S2000.

Cars& Drivers and other magazins that i have read clamed that the S2000 is capable for 0-60 time is 6.2 but S2000 owners clamed that the car is fast at 5.2 sec 0-60 time. I personally raced with them few times on my stock 87 951 with an 89 engine in there, with me and my wife were on a car the first gear he bit me by half of his car length, 2nd gear i gained back and 3-4 gear i moked him. There was another on the freeway with my 88 none S with chips. When i looked to my right side windows, the S2k owner was laughing at me at 70mph, i shifted to 3 gear and gunto 90 then shifted to 4 gear to leave him on the dust. I stopped racing them because they are wasting my time.
