When I said 5300rpms I was not talking top gear at WOT. I stated the terms in which a stock engine can reach 5300rpms, in neutral foot to the floor. Absolute as high as it will allow with the stock governor and stock pump settings.I find it hard to believe that your modified engine with modified governor can not reach above 5000rpms. I have gps speed verified and then calculated exact rpm's of the motor with scirocco gear up.org, and I have had my engine (on a regular basis) to over 5500rpms, in second gear with load. My engine being a stock 1.6 na with bigger CAI and straight through exhaust. Fully shimmed solid governor as well. What you have more than likely read is that BY 4800 rpms on the stock governor fueling is cut to an abysmal %80 of normal. Do you have a GPS? Without an accurate measure of your speed and or engine rpm, I can't hold your acclaims accountable. Unfortunately I am on my phone, so I cannot provide you with the emails from Giles..
A GPS is not an accurate speedo over short distances. Perhaps over 20 miles, but the 10 meter built in error in the worlds best system makes instantaneous readings suspect.As I have said before, not all VW IDIs nose over at 80 mph. I have driven a large number of these cars and some stockers with 4 speeds will do 100 and many will do close to 90, with flow screw and timing mods on a fresh motor. At 275 psi compression, not so much. At 450+ its another matter.
There isn't room for things to fall out of place, simply the plunger would not come back down fast enough to be pushed back out to inject to the next cylinder.
The Bentley lists the max rpm for the various engines. IIRC, non-turbo 1.6 is 5300 and you can definitely get a stock engine to rev that high in gear. I've done it. The little dots on the speedo represent speed for max rpm for a given gear with stock size tires.
and thank you all, for the numbers..
