Greetings

Don't forget that the S3/ED30 gearbox has different gear ratios compared to the "standard GTI"! :happy2:

And the speedometer is also not a precise instrument to use for comparison!

As I see it the video is taken while the car is "sitting" on dyno! NO air- or rolling resistans is slowing the car down!

No matter what the circumstances around a given car is, the speed will always relate to a given rpm, for example 100mph i 4th gear is 4500rpm. No matter isf the car is on dyno or on the road, 100mph in 4th will always be 4500rpm in this specific car.
To change this, the gearing needs to be changed, wheelsize or gearratio in gearbox.  :wink:

Are you sure? Never heard of there wing longer gears in the standard GTI compared to the Ed30 and S3 considering they all have the same part number..

Also, dyno or not the speed will still relate to RPM..

YES!

And they do not share all parts! You can check it yourself by looking in ETKA! :happy2:

On what basis?

jonnyc is comparing his S3 "gearing" with APR's "standard GTi" gearing! And they are NOT the same!

And the speedometer reading in the GTI is way off from reality! Use an PerformanceBox or any other precise GPS to see how much. You will be surprised how much off it is!

On the basis that they can tell us all relevant detail and put this thread to bed.

Sorry, forgot that! :happy2:

And I just replied to this thread before someone embarrased himself by comparing to different gearbox ratios!

It was kindly meant! :drinking:

Ok explain this then..

Just simply..

A MK5 GTI with DSG box.. Check out the speedo and revs at 12 seconds in.. 5000rpm at 60MPH



A MK5 GTI with Manual box.. Check out the speedo and revs at 7 seconds in (or exactly as he takes 3rd gear)  ... Again 5000rpm at 60MPH



Niether are ED30's and AMAZINGLY both are exactly the same as my S3 / ED30 and my 200hp GTI that I used to have.. Which one is the odd one out I wander? lol..

You guessed it..

Check out the original video again, 29 seconds in.. 5000rpm in 3rd gear and 69mph.. I think its pretty simple?



Think your going to have to try again  :wink:

Oh and for the record I dont think I was embarrassing myself..

Are the US-spec cars geared differently?
