... and it keeps getting better, even after 600 miles...

While many people said the engine would get noticably stronger from 600 miles to about 5000 miles, I wanted proof, so...

I raced a broken-in S2000! First, we found a secluded, no turns, no entrances, zero-traffic, no-cops two lane straightaway.

Silver S2k: 1800 miles
Black S2k: 22000 miles

Then, following a rolling start, we accelerated up to 6000 RPMS, and punched it! The two cars were even up to the end of second, where he started pulling away and even more obviously in third. The starts were not 100% synchronized but I would say he had (effectively) a 3 car length from rolling start to 100--

So there you have it, experimental confirmation of your long-suspected hunches. Next, does anyone have dyno numbers (on the same car) at various miles such as 600, 1000, 5000, etc to further prove this point?

P.S. For comments about street racing, please PM me at ting@kissmyass.com

 

Why stop at 100? You should have kept on going to at least 161mph. The test is inconclusive due to the low speed.

 

I would be worried that even among 2 brand new S2000's you would find performance differences due to minor variances or "defects".

I think racing 2 cars would be inconclusive because of that. You'd need to Dyno a single car repeatedly over the breakin period to prove such a theory.

I have heard about Type R's getting low low 14's in the

 

Of course, doing dynos of the same car over a period of time is inconclusive because atmospheric conditions can totally vary the output. Doing comparison races with several stooks all at the same time and looking for patterns is probably the best way...

One time you may get a good start, next time you don't. One drivers skill may be better. I'd say there are more variables to it than the Dyno...

I'm not saying that one S2000 was not quicker than the other ... but there's a factor that could have been a lot more relevant that the 'number of miles' - that is weight. Were your cars the same weight (equipment)? Did you have anything loaded in yours? How much do you weight compared to your friend? How much pertol in your tank compared to your friend? All these things can add up easily to 100kg difference (8% extra weight) and will show a fair bit of preformance discreptancy.

 

I have to second the opinion. I can feel the car is getting faster.....it just winds up easier (IMHO).

 

Boy, I sure hope it does. Mine's only at 300 miles and I'm dying to go full-VTEC, having ventured above 6000 rpm a couple times so far. And you guys are saying it gets even better after that ...
