I'd like to note that Porsche speedometers, if used with the proper diameter tires, are notoriously "slow", as in they will read 150 but you are really going slightly faster than that. That also goes for their acceleration and braking times and speeds. Porsches are even better than they say! Just go thru some back issues of nealy any car magazine that tests them and you will see what I mean. Later, Clayton
Date: Tue, 25 Jan 2000 19:39:29 -0800 From: "Dave M." <> Subject: Top speeds - reality check bounced Just a quick note on the ultrafast 944. Since no mention was made of radar guns or stopwatches, I'm going to assume that 180mph reading was from the speedometer. And, I hate to break this news to y'all, but speedos are notoriously inaccurate- especially over ~100mph. Both my GLI's read 5mph high @ only 75mph (says 75, actual 70) and that's with stock wheels & tire sizes. At 150 (if it would get there) the error would be at LEAST 10mph. My bike does the same thing. I got my bike flat out in 5th gear once, and the speedo showed 165mph. I know that's not accurate, since the bike's true top speed in 6th gear is ~167 (from bike mags with radar guns) and the top of 5th is mathematically ~150ish. Anyway, if the 944 speedo said 180 I'd suspect something more like 160 in reality, perhaps lower; unless this was a really, REALLY pumped up 944. I always take these numbers with a big ol' grain of salt unless the claim is backed up with some serious evidence (radar guns, timing lights, etc). BTW, to the lister who was skeptical: Car & Driver tested a 99 Camaro SS convertible and it went 160mph, the C-5 Vette hit 171. The GTI & GLX VR6 both did ~134. Electronically limited, I hope. One last bike tidbit (sorry can't resist!) is about the Suzuki Hayabusa GSX-1300R. It has been radar gunned, bone stock, at 194-196mph by several different mags. However, they all show 210-220mph on the speedo when flat out. This thing has 165hp at the wheel, and runs high 9's at mid-140's in the quarter. Corners pretty good too for a big bike. :-) A2 content, to avoid getting banned for off-topic banter: Is there any way to correct the A2's speedo error? It's really annoying! Will a correction doohickey thing go between the transaxle and the speedo cable? - -Dave 2 1990.5 GLI 1991 GLI _____________ List Sponsor: http://www.netsville.com To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message See us on the web at http://www.a2-16v.com Visit the 16V Homepage at http://www.gti16v.org
