Well, the R34 does stand for all things that is hating America :rolleyes2:

GTRs are not magic. They have a very good transmission and run super low gear ratios. I would still take a mildly modified Z. The real advantage is that you actually have to be skilled to drive a Z. The GTR will drive itself until pushed past the limit. I do thing that GM should offer a track specific alignment which Nissan does.

I am really disappointed that the Stingray doesn't have a dual clutch option. After the GTR was release Porsche developed the PDK, Audi's DSG was completely re- engineered, and with the Audi the Lambo gearbox obviously was re-worked. It worth a second down the quarter much more on a road coarse. I'm saving for the PPG t-56 gearset. $4700 for parts, but worth 4 seconds at VIR. Why is everything so expensive?

I know the LFA, which is several hundred thousand dollars was originally designed with a dual clutch, but they specifically went back to a single clutch for feel and "involvement". Since it's not a track car they thought the loss of a couple hundredths here and there wasn't a big deal. If we're talking about a small amount of time my guess is GM made the money calculation that it was more important to keep the base price down. The value equation for Corvette is critical. Remember the base Vette is in the 50s. The GT-R is in the 90s. Even the base 911 is in the 80s. As for your PPG gearset, it costs that much because they can get it. The only rule of pricing there is. :) |
MTI Racing won last years UTCC and estimates a .4 second reduction in upshift time with the PPG gears. That's 1.2 seconds of acceleration that is not happening in a 1/4 mile thats 2-3 MPH. The PPG gears still require you to lift the throttle slightly. The LFA is infinitely faster than any manual except for a full dog clutch-less box. The LFA still only has one clutch so there is a finite amount of time the car spends not accelerating. The Dual-Clutch transmissions have the second clutch grab the next gear and the short gear will free-spin. This means that the lower gear is not released until the higher gear starts driving. The end result is the car is continuously accelerating. Huge difference. MTI estimated on a very large course like VIR the PPG gears are worth 4 seconds. I'd prefer to see the next generation Z or ZR1 have a truly modern transmission. Fuck the blower.

That makes sense. I thought you meant 1 second in ET, not non-acceleartion time. That's a compared to an average shifter guy I suppose, but the guys who are hardcore about dragging get pretty ridiculously fast, power shift, etc.
Good point about the LFA, I was comparing apples to oranges. Maybe a good step up would be a dual clutch for the Z51, since it is a premium package, and a dual clutch twin turbo for the next ZR1, since that's a flag ship. I think a pretty solid argument could be made for that in a product line up. The base remains very approachable, but it spreads out to monsters, sort of like America's Porsche . . :inout: |
