EVO preview of new RS
#2
"We’ve gone very aggressive on the ignition timing,’ says Preuninger, ‘and with the better intake we have had to fit a revised, titanium exhaust. With the Sport button engaged and the valves open, it’s now louder than the Cup car."
"it’s littered with weight-saving details, and that doesn’t include the fabric door-pulls, which are an appealing gimmick but nothing more."
"Cabin-wise, it’s business as usual, with a few tweaks. I’m undecided on the fabric door-pulls: they’re cool but a touch disingenuous." No ****- thanks focus group for the one dumb-*** detail of the entire package.
"he just knows that the RS package is far superior on-track, which is where the majority will be used. They’re expecting something like a 5sec advantage at the Ring."
"‘The tyres are now the same width as the GT2, a 325 section. The wheel rim is the same width as before but the offset is different, so you can’t swap them with the regular GT3 wheels.’ "
...good stuff.

Can someone please explain to me how you obtain a higher compression ratio (12.2 RS v. 12.0 GT3) by ignition timing and intake plumbing alone???
The RS engine must have something different internally from the GT3, right?

Compression ratio is always a static measurement, a direct mechanical (or would that be hydrodynamic?) calculation. Timing/plumbing have no effect on the calculation. They would have an effect on cylinder pressure or charge density which is totally different from CR.
In other words, CR is simply a factor of the empty volume left in the cylinder at TDC. Less volume=high compression ratio.

"And you notice the new gear ratios, especially second and third, the way you used to in a 205 GTI through that wonderful telltale of reduced intermediate gearing – the engine note doesn’t subside quite as much as you’d expect after each upshift. "
First car was a 205 GTi...funny how it continues to be a touchstone for EVO....was an absolute blast of a car.

so;
marginally faster than a standard GT3 (5 sec on a 17 mi strip)
much nosier
not much lighter (remember, this is an ROW unit)
big wing (is that better or not?)
finally, unless they are perceived far differently than the .1 was, only a few will see the track anyway.
guess i'm happy with my GT3!

I thought this was a strange quote, since the gear spacing is identical (same rev drops on upshifts) as the non-RS. It only has different spacing between 5th and 6th (in favor of the non-RS). The shifts in the lower gears will occur at slower speeds at redline (thanks to the lower final drive), so the car will have more urgency (but engine note should be identical).
