1/4 Mile Question

[Martin]

I have noticed that some slightly tweaked 172s are doing 1/4 miles at around 14.7-14.9 secs @ 94-95 mph. When you compare this to cammed/modded 2.0 valvers and willys which do 14.4 ish @ 94-95 mph, how can the older style clio get terminal speeds so similar but run 0.3-0.6 secs quicker up the strip?

Weight, gearing, launch, etc...

So many factors affect the run time & terminal speed.

For example, both my Cup & CTR can run 14.5s however the CTRs terminal speed is 4mph faster!

My guess.

Mk1, Faster off the line.. but then a Mk2 would reel it in.

(Or the other way round.. )

Im guessing if its got cams the power will be a little further up the rev range. Hence a slightly slower start (prob minimal) then a surge to take it past the 172s.
