Hi S2Ken,
Not sure if you're aware, but the S2000 has 6-speed gearbox as well. Also it has shorter gearing that the BoxsterS in all but the 1st gear. Here's the gearing for both cars:
--------------
BoxterS speed at 7200 revs:
1st = 63km/h
2nd = 109km/h
3rd = 159km/h
4th = 198km/h
5th = 237km/h
6th = 287km/h
-------------
S2000 speed at 9000 revs:
1st - 69km/h
2nd - 105km/h
3rd - 144km/h
4th - 186km/h
5th - 223km/h
6th - 266km/h
--------------

About the LS1 ... I'm not from the States so I'm probablaly know less than others, but the only LS1 I know is is a Corvette (not a Camaro). It was the 'super' Vette about 10 years ago that had the LS1 engine (5.7L V8). Then engine was made/designed by Lutus and produces some serious power. The LS1 Corvette is still regarded as one of the finer automobiles around. I'm not sure if I'm on the right track but that is the only LS1 I know of.

 

actually thats the LT5 engine from the corvette ZR-1.

Camaro's get a similar LS1 engine to the corvette but they obviously dont make as much power. the LS1 makes 310 hp (325 for the SS) and the corvette makes 350 hp (385 for the LS6 engine).

So while this LS1 Camaro had about 50 HP on me I take it that his heavier car was what was keeping him back?

That poses an interesting question, in that how much HP is needed to overcome how much additional weight? Must be a formula somewhere?

For example the S2000 weighs a couple hundred pounds less than the Boxster S, if the Boxster S went on a diet and shed 200 lbs, how much faster would it be?

And finally, if I lost 25 pounds, would I run faster?

 

I have a couple of friends that own a Boxster S and I have raced them both repeatedly. Anytime we race from a dead stop I fall back a car or so initially and then it's pretty much dead even up to about 120 when I start to gain slightly. If we race on the highway (65-70 MPH roll ons), I pull slightly away. Keep in mind that my car has about 12,000 miles on it and is MUCH faster than an S2000 with 2-3,000 miles on it.

[QUOTE][B]BoxterS speed at 7200 revs:

 

Derryck, that's the same thing I experienced racing Boxster Ss around here. I raced them at around 3.5K miles.

 

Jwkc , those speeds are what the car is geared to. In theory if an S2000 (or BoxsterS) could reach the redline in 6th gear, than that is the speed you would be doing. Though, under 'normal' conditions, cars encounter way too much air-resistance to reach that kind of speeds or the redline in the final gear. Most cars are over-geared in the last gear so that reaching the top speed is deterinied by the air-resistance and not your gearbox.

For instance my old MR2 ('93) was geared to 255kph in 5th gear (final gear). 230kph or so as the best it could do though.

A local HSV R8 (265kW) is geared for 330kph in the final gear. It will not get anywhere close to it, but it is a 5.7L V8 and having a 'tall' final gear helps with the fuel consumption when cruising.

ps. Very nice Porsche you got there :-)

 

I would disagree with your specs on the LS1 in that I went to LS1.com and there seems to be an awful lot of people running their stock LS1's in high 13's to mid 14's in the 1/4 mile. Yes there are owners who claim to run in the low 12's with some modifications, but either the guy that raced me had no mods or he was a bad driver or both. He was a little heavy set, maybe that's why it said "Phat" on the plate.


I wonder what would happen to his F-body if he tried to take a corner at say 80mph?

Any chance he could stop in under 350 feet?

Ever seen the interior on one of those?
