How fast (really) is a remapped ED30?

[Kiddfrost]

Just my 2 pence worth on the std Ed30/mapped gti subject
Went up against a standard ed30 in a revo'd gti. It was up a long hill and I got to 1.35
I was changing gear at about 5300rpm (anything after thats a waste of time)
I must have pulled away at least 4 car lengths from him.
Maybe because it was up a hill the extra torque on a mapped gti made more of a difference?

....Stage1 or Stage2 Revo?

What other mods?

Have you considered that at 135 mph (on your speedo I presume, and if so, you were doing considerably less) the Ed30 driver might have seen sense and backed off? (I'm also assuming it was in the UK)

Stage 1, Boost 8, timing 5, fuel 9, K&N Panel and has been vagcom'd to death.
13.5mph, yes on the speedo, so you can take around 8% of that which would be around 12.4mph
I'm quite sure he never backed off but we'll never know I guess.

I'm also assuming that changing at 5300rpm is a waste of time too.. You can add another 1000rpm to that before changing gear..

If you look at the various graphs around for mapped 200ps gti you will see bhp goes flat at 5krpm, maybe with a slight peak somewhere after. Torque is also taking a dive.
I like taking it to the red line and have tried a set distance changing at 6.5k and just over 5krpm. I get a slightly higher terminal speed changing at just over 5k. Your lucky, you've got an ed30 (I wish I had one by the way) which pulls hard all the way to the red line.

thats a rather long hill to get the car to 135mph??? if so only 4 car lenghts means its about the same in power which is what the whole Argument was about or about 3-5 hp or slightly higher torque of around 20 lb ft!! 

Yes, it is a long hill and you're right, there's not a lot in it. From my experience it is a little quicker

Here in SA it's believed that the BWA engine code GTI has 160kw (around 215 hp i think). It has been confirmed by numerous 'dyno's' (what we call rolling roads here). As opposed to the earlier GTI's which had much less. Haven't tested mine so don't know what the deal is.

The BWA engine using 98RON petrol will produce more than the vw quoted 200bhp...

My car changes at around 7200rpm in S mode at full throttle.

Isn't that just in first and second gear it goes just over the redline? and then round 6500rpm in all others 

Don't forget that both "auto" modes of the DSG are controlled by and adaptive ECU.  This uses fuzzy logic, and the ECU "learns" the style and habits of the driver, and adapts the shift pattern accordingly.  If you are always lifting off the throttle in 3rd in S mode, then the box will adapt its' shift patterns accordingly.  I notice that when SWMBO soley drives the GTI for any length of time, the shift patterns do drop in the rev-range.

....Ah, that explains everything!

I invariably shift gear as she just kisses (without tongues!!) the red zone. Also, my torque curve delivers over the 250 ft lb mark between 2,600 and 4,700 (as dyno run) - If that means anything in the context of this subject.

Sorry, but that is wrong.  The current BWA engine in the standard GTI is officially rated at 147kW, which is 200PS, or about 197bhp.  The only 2.0TFSI engine rated near the 160kW is the BUL engine, rated at 162kW/220PS, and was only fitted in the 2005 Audi A4 DTM edition.

All "standard" GTIs, weather the early AAX, or the current BWA - are all rated at the same 147kW output.

The Edition30 and Pirelli GTIs have the BYD engine, and are rated at 169kW/230PS, whereas the Seat Leon Cupra uses the BWJ engine, rated at 177kW/240PS.

Finally, the "daddy" engine is the BHZ, rated at 195kW/265PS, found under the bonnet of the Audi S3.   

Furthermore, neither "horsepower" (hp), nor "brake horsepower" (bhp) are used by Volkswagen Group to assess the engine output, so by using such figures can be slightly misleading, due to the conversion factor, and the number of significant figures used in said conversion factor.  And ONLY Yanks use "hp"!

"Optimum" shift changes can vary with momentum too.

If you are on a linear acceleration, ie constantly building speed, then optimum acceleration should be achieved by letting the revs rise to the red line (or to where peak power starts to drop).  However, if you are at a constant speed, and wish to accelerate, then to "initiate" the maximum rate of acceleration, you need to be in the rev range where maximum torque is generated, which is usually (in a petrol engine) a fair bit lower than max power revs.

  haha...cool TT You certainly know a lot about this stuff!!
Have a read if you will on the local forums here:
http://www.vwclub.co.za/phpbb3/viewtopic.php?f=3&t=66952&p=642409&hilit=BWA#p642409

There's various other threads on boards here in SA about this topic. Widely believed that the BWA is up on the older ones, even though VW still market it as 147kw.

....Yep

Hence why it's a good idea to actually read the rev counter while driving as well as hear the engine's revs. My dyno plot shows max torque of 258 ft lb very evenly between 3,100 and 4,000 revs.

Pedantic correction - The BWA engine using 98RON petrol may produce more than the Volkswagen quoted 200PS. 

However, the BWA engine is rated according to German DIN standards (which are arguably the most reliable in the world), and most BWAs can reasonably be expected to reach the quoted output.  Some may well exceed it, and some may well fall slightly short.  But VW do not submit every single engine off the production line for testing - which is why tollerances are allowed, and why differences may be found!   

"VW" is merely an "icon" of the Volkswagen company, in the same way that the four interlocked rings are Audis' icon.
