I'd take an RSX-S over a DC4 but not a DC2 even, the RSX's are, IMO, complete failures as a replacement for the US GS-R/ITR cars.

I hope the FRs turns out to be 2+2 version of a miata but with masculine low slung styling, and a much more livelier powertrain.

Well the FR-S I think is Mac strut up front too =P I don't mind MacPherson struts actually, I mean it's good enough for Porsche. The main thing is to dial in negative camber, compensating for the lack of camber gain under compression.

Sub, why haven't you bought your Genesis coupe 3.8L yet?

Mac strut does make it easy for caster and camber adjustments. Porsche also used some really horrible suspension designs in the past :P

Sorry for going off tangent here: is it true that under normal driving condition (revving up to 4K max on the street), a S2K would be slower than a cavalier because of less torque in that sense? Somehow I got this impression but I do not know where I get this. Maybe this is just another urban myth w.r.t. S2K.
BTW, if GT5 has any bearing on the performance of FR-S, I think this car is going to be as fast as a Z (maybe a bit slower, but definitely faster than mx-5) on track. |

The best Cav motor I believe had 180ftlbs and 135hp. I have no idea which is faster in a race where the S2K has to shift at 4K and the Cav has to shift at.. redline? I'd guess the Cav then. If it had to shift at 50% of it's redline I'd guess the S. No idea though and it doesn't really matter does it?
I rarely revved my S2K (or my low torque hondas) past 4k in normal street driving and have no problems going with the flow of traffic.

A cavalier has to do with almost only half the power of the S2k, so no, there is no way it would be faster. At 4k rpm on the s2k the engine is giving you over 100 hp, while on the cavalier you'd need to be 75% up the rev range to get that (or something). No way the gears would be retarded enough to make the cavalier "faster" at low speed. Think of it like this, "normal driving" cuts away more power on the s2k, but the s2k is geared shorter since it is performance oriented, and the s2k is so far ahead in power that the "normal driving" disadvantage isn't enough to make it lose. If you want more solid numbers, I'm getting somewhere that max power on the 3.1L gm motor comes at 5200rpm. The s2k has max power at 8300, rev limited at 9k. Let's say we're revving to 4k on both engines. At 4000 rpm we probably have something like 80% of the power on the gm motor, while we have about 45% power on the s2k. However the s2k has 50% more power in the first place. So at 4000 rpm the s2k is only down maybe 15% in actual power. Weights appear to be comparable. Here's the catch, the s2k is a very hardcore performance car, and I bet that the gears are short enough to compensate. Say we're in first gear...and both cars were designed to accelerate at the same rate in first gear. Then the s2k's gearing would be comparatively 10% shorter (to give the same torque at the wheel) to match the cavalier, and it would lose if we limited revs to 4k. But I am willing to bet 20 bucks that the s2k's gears are considerably shorter (read: a crapton higher torque multiplication), and it would hit that 4k rpm point much sooner. The s2k has a very good 0-60 time, which supports this idea since 0-60 is the only time when you even need to think about the stuff in the lower 75% of the rev range. Another thing is that the s2k has piss poor fuel economy for a 2L engine, which is another indication that its gears are extremely short. If you go faster, then the power disadvantage can't be overcome obviously, but that's what those extra 5000 revs are for right? ![]() The thing is this: if you have a lot of revs, but your car is somehow slow at lower speed, that makes no sense because a lot of revs=performance oriented=they want it to be fast at all speeds, not just have a higher top speed.

Have you ever driven an S2k? Even when they upped the displacement to 2.2l it could be described as 'gutless' when that digi tach wasn't getting up there, such as very conservative city style driving.
That is a great example of a motor that thrives on revs. |

Weight and Gutless engine...
2003 Cavalier dyno graph (stock)
http://www.dragtimes.com/2003-Chevro...aphs-8862.html 2003 S2000 dyno graph (stock) http://www.dragtimes.com/2003-Honda-...phs-11765.html So, I understand that S2K is a fast car that can achieve good 0-60 time whereas cavalier maybe a POS in 0-60 time. However, the key point in this discussion is at the rev limit of 4K. At 4K point, Cavalier has > 100 HP and > 125 lb-ft of torque, whereas S2K has < 100 HP and < 125 lb-ft of torque. If we just forget about the gearing issue and the free revving characteristic of S2K for now, just compare it on numbers S2K is inferior to Cavalier. I think this maybe the complaints of the "gut-less" motor. In the regular city driving, the motor feels gutless. I have only driven a cavalier but not S2K so I know that torque at the low rev. There might be a moot point to determine which is faster unless someone actually tried it. But we can talk about the torque/hp and how it can be related to FT-86. |
