Very interesting - APR care to explain?
« on: October 21, 2009, 09:02:14 pm »
So I think most of us have seen the APR video of the 430WHP APR Stage 3+ car on Youtube..

For those that havn't here you are..



Anyways I thought I would have another look just to see what was going on, maybes get a little comparison against the S3 to gauge what kind of numbers im running currently.. It does look very very quick if you concentrate on the speedo..

I have a video of my car doing a pull through the gears and noticed that it flys through the revs far quicker than the APR car, but the speed is far lower.. Which brought me to the following..

The APR car is doing 60MPH at 4300rpm in 3rd gear.. Just for a comparison, both the ED30 and the S3 are doing 5000rpm, so thats 700rpm, or x amount of MPH that its over reading, and thats only in 3rd..

If you watch the video from the 50 second mark you will notice.. So they do a pull in 3rd / 4th and a little in 5th

At 7000rpm its doing..

3rd gear - 92mph
4th gear - 125mph

And at the 16 second mark hes at..

5th gear - 159MPH

Compared to the S3 that is doing.. (only have figures for 3rd gear)

3rd gear - 80MPH

So thats 12MPH more just in 3rd lol..

So basically the conclusion that I have came to is that either its the car MASSIVELY over-reading or APR have fudged the video.. If its the latter then thats a pretty piss poor way of making a car look faster than it really is.. Although I suppose its taken up until now for someone to notice lol..

Anyways just thought I would point it out and see what anyone else thinks?  :confused:

And hopefully someone from APR can explain?  :happy2:

Jonny

Im not disputing the way it goes through the revs, but its the speedo that im questioning.. Looking forward to the response from APR  :smiley:

For example..

5k to 7k in the APR Golf in 3rd gear takes 2.45 seconds.. (recorded from the video)

5k to 7k in the S3 in 3rd gear takes 1.77 seconds..

Time the speed and its a completely different story, if that all makes sense lol..

big wheels , differential ratio/box ratios , or a modified speedo signal ???
apr would have to defend their claims (risking total loss of reputation if found to be dishonest....), so Id be  :surprised: if they tried to hoodwink us (although its possible)

Lol, hence the reason I posted on here.. There are TONS of APR bum boys over there too which would have seen it as a personal attack on APR and not seen it for what it is.. A simple question.. Why?

Most strange. I'm with John_o on this one. Some kind of alteration in the wheels, ratios, speedo would be the most obvious. However, to post it up as a genuine advert for how the car accellerates is just plain stupid if they have altered something to make the vid appear more impressive. :confused:

Would a simple gear ratio change not explain this? If the car was going through the gears too quickly due to the increased power longer ratio's may have been used?

I might be talking complete rubbish as TBH when it comes to the technical things like this I dont know my arse from my elbow...  :ashamed:
