So I know we’re talking about this in several threads, but I had an interesting “discussion” with a friend about 1/4, 60-130, dyno, etc.
I personally love the 1/4 as a test of a cars overall performance, but obviously the big hp rwd guys started looking at 60-130 as a new means to test their car and eliminate the driver as much as possible (i.e. a dyno more or less).
The argument, I mean discussion, basically wrapped up with him saying that if he went to the track, and lost to a car by ~3-4 car lengths, but then as they headed home, did a pull from 60-140/150 and won by ~3+ car lengths, he felt it was ridiculous for the other car to say they were “faster” (which turned out to be the real root of the problem, how to define that term). This boiled down to him saying the car with more hp will always win (more being 50-100+hp more etc, not 10/15hp “more”), which is tough to argue about in the 60-130, as it’s just setting the trap speed.
My retort was that you might as well just race dyno plots rather than anything else. But with more and more big hp cars coming about, more and more flop in the 1/4 but set stunner 60-130 times (some like UR etc still set very impressive times, but for the # built by all sort of tuners, you know what I mean). Obviously there’s a lot that goes into a 1/4 where the 60-130 is a more isolated test of power. But I understand his definition of “faster” to an extent.
So I just wanted to see what people thought of that.
What kinda got it started was talking about my car and his car (SRT10 viper, tuned, HFC, Corsa CB, Intake, new geared rear diff, 485whp 475wtq). Due to his lack of traction I can hang with him decently down low, and would love to race him from a dig, but he’s never launched it and probably won’t. But on the interstate, that car HAULS ASS. I think at the strip he would set a pretty horrid 1/4 (horrid considering mods, never been before, etc. Stock they claim 12.2@122), but his trap would be decently good.
We also have a friend with a 997 Turbo S, they’ve been shown to do 10.7@128 stock with a 2.7 0-60. But on the interstate, the same car only put about 2-3 car lengths on a 335 with JB3, meth, intake (what should be ~380-400whp) from about ~60-115. The Turbo might be a bit skewed though, b/c it gets to 60 SO fast & in short a distance that it has extra time to build mph for the trap (vs a late spooling car that starts slower and then has a rush of power). In that example, the Turbo should have at least 100whp if not close to 130whp more, but yet only pulled a couple of car lengths. Not the result any of us expected.
Now that he has his viper, he wants to run again as it seems significantly faster (and has dyno’d about 100whp more than his 335 probably would have). So again, interesting perspective. IF they run again, he’d hold pretty darn close to the Turbo depending what mph they start at. But on the 1/4, the Turbo would beat a stock one by over a full second (~10+ car lengths) and probably beat him by a solid to 2 seconds if not more (PDK with Launch control, so it’s gonna be consistent).
This largely boils down to area under the curve vs peak and/or total hp, and driver/car ability (launch control etc). The 60-130 basically is just a dyno run, but some people only do pulls with other people in that scenario. For me, the closest 1/4 track is an hour & half away, no one really races from a dig, and the people who do go do pulls, all do them on the remote interstate starting at 40-60 and shutting down whenever they feel like it.
