Golf R Observations and Questions

Can I ask what tyre pressure you had?

[Ideo]

Curious as to why you didn't go with an 8P S3?

the 20k price difference.

I could get an 07/08 for the same price, but for numerous financed based reasons it comes out cheaper to get a new car. Plus, it's a new car and after years of owning second hand cars I just wanted one.

Can I ask what tyre pressure you had?

39psi all round.

[Big_Dave]

Ok, i think if you troll other threads you will see that most of the "in the know" guys recommend lowering pressure to the low twenties range.
i think Guy Harding said they lowered their cars pressure to 18psi for the Motor drag section.
has to do with having less tyre spin while accelerating?

sounds like you had some fun while testing though.

Shouldn't make that much of a differnece with the 4Mo system/Haldex though.
I believe the 18PSI was for their Stage 3 GTI (FWD) hence the need to reduce wheel spin.
I would still have them dropped to low 30's.

[Big_Dave]

yeah, 30 would probably be ideal.
i have also heard those that have reflashed the DSG software which allows a 4,500 RPM LC get much better 0-100 times as the standard 3,000 RPM LC setting gets a bit bogged down torque wise before it spools sufficiently to really get up and go.
If anyone has had the DSG reflash i would be interested to know?
I know APR don't do it.
It is one of the Euro companies.
HPA I think????

Just found reference from another forum.

"DSG performance involves a synergetic relationship between shift call outs, engine load, driver demand, and mechanical execution. Within these relationships, a harmonic balance must be maintained to ensure the various integrated systems work together and do not overpower their basic limitations. HPA's Stage 2 DSG Program has the following features:

Progressive Shift Response:

One of the keys to our success in tuning the DSG software comes from our command of the clutch pressures. We are the only company to offer a progressive shift response upgrade which, through a scaling effect, optimizes the DSG’s durability, and retains known comforts and mileage. Under tip throttle and highway usage, shift response is improved by approximately 1/3 faster than factory. Between 50% engine load and WOT, our software is scaled to shorten the shift response up to two thirds quicker than factory. This feature is in effect in D, S and M modes. Our scaling effect synchronizes the hand off between inner and outer clutch packs depending on the load and acceleration demand applied. This eliminates unnecessary clutch slippage under full load accelerations, which reduces clutch wear.
Note: any non progressive software will prematurely damage clutch packs as different engagement response windows are required in order to manage the variables of different situation and allow the mechanics within the gearbox to conclude their transitions.
Torque Limit Increase:

Working in conjunction with our progressive shift configuration, we have increased the DSG Gearbox’s ability to transmit torque from 350nm up to 500nm while still ensuring the stability and capability of all the mechanical moving hardware within the DSG gearbox. With an HPA performance program, The DSG computer will no longer initiate steps to shed engine torque when the factory 350nm limit is reached which unleashes the true benefits of any engine modifications.
Launch Control:

With HPA's Stage 2 DSG Software, launch control is activated on any vehicle (ie Audi A3, Jetta/GLI) that did not come equipped with factory launch control.
A perfect launch out of the hole accompanied with a great 0-60 acceleration is one of the best ways to show off your performance mods. HPA’s DSG software upgrade enables the Launch Control feature on any car that did not come equipped with it from the factory. Furthermore, improving on the uneventful factory launch, we elevate the launch RPM to 4750; putting you in the sweet spot of your power band for a spectacular launch while maintaining a safe range of pressure that can be applied to the factory clutches to provide maximum grip without slip.
Increased Red Line:

Putting you back in command of your engine’s power at the upper RPM range, we have raised the DSG transmission’s rev limit to 7150 RPM as this optimizes the FSI engine’s compressor map and maintains the safe operating range of the V6’s valve springs. Note: the DSG rev limiter will be overridden by your engine’s rev limiter, so this feature may not be utilized with factory (or some aftermarket) chips.
Eliminated Automatic Shifting:

When commuting in traffic and looking for fuel economy, the brain behind the DSG is a mastermind at selecting which gear to be in. When it comes to spirited driving, the factory Sport mode can be quite aggressive, but many complain at how it overrules the driver’s input in situations like cornering.

With HPA’s performance programming, we have put the driver back in complete control.

In M mode; automatic up-shifting at wide open throttle has been deactivated, as has kick-down; allowing you to bounce of the newly redefined rev limiter and maintain your gear at will.

When you opt to take over the paddles in S mode, only at Wide Open Throttle will the software automatically shift at the newly defined red line. Up to 95% load, you will have the benefit of the removed up-shifting and kick-down to take control over your gear changes. This ensures less experienced drivers still get an automatic gear change under WOT demand.

In D mode, the factory up-shift and kick-down settings are maintained.
IN-DASH GEAR DISPLAY

When in D or S mode, the active gear is now displayed in the instrument cluster to the right of the PNRDS icons where it wasn’t previously (R32 etc)."

I believe that HPSOV's car is stock, not even with any Stage I tune yet. So this talk about DSG this and that is not overly relevant. The car _should_ do consistent 0 to 100's in ~5.7 seconds.

However:

It was 25 degerees and I had a full tank. All runs were done in Manual Mode, using Launch Control, letting it change gears when it got to the redline. I did 2 runs in each direction, results were-
6.05, 6.38, 6.41, 6.83

So two things there. Whilst 25 degrees isn't that hot, doing multiple successive runs will start showing the deficiencies of the cooling systems (intercooler as well).
The other is what I've highlighted in bold.
Why would you put it in manual, and then let it change gears via the "engine protection" of its auto redline upshifts?
If you want it to change gears, then put it into S. Otherwise, if you've put it in manual, change the gears yourself!

So most people are not as "in tune" as the car itself is, using S gives you the fastest and most consistent 0 to 100 times.

Damn forum whore, I was just about to start typing that

LC + S do a bloody amazing job for this type of thing. Crazy not to use it!

[Big_Dave]

Yeah, sorry Corey,
i didn't notice the manual mention.
I thought LC only worked in S?
(LC = ESP off, S mode, foot on break, push down pedal, RPM revs to 3,000, release break)?
That right?
