Golf R performance upgrade NEED ADVICE!!!

[Guy_H]

To the original poster anleizhang - If you would like your car to be used as a comparison test between "Recode" software & APR at an independent dyno, I would be more than happy to oblige.

I would suggest Mainline Dyno's HQ and run by the Mainline's operators (Todd & Craig). We would love to see a back to back test of the two versions of software on the same car at the same dyno. I am more than happy to pay for the dyno time and I can send one of my dealers to Mainline to flash your car with APR.

If it turns out that the "Recode" makes more power & torque and better curves than the APR on the same car, same day, I'll give you a $1000 gift voucher to use on our hardware at any of our dealers.

Of course we need "parso_rex" to agree to the challenge.

Failing this, if anyone else has a Golf R they would like to run back to back with the same hardware, please let me know.

Nek minute...

Hmm so whats in it for me ? I do like your cat back exhausts ?

The thing is, typically, I would spend more than one day on tuning a car to this level with quite deal of time on the dyno logging and then responding with further files to the data I have seen in the logs. I have no problem with any sort of comparison but in my case it costs both money and time - not just a singular cut and paste of a generic file unfortunately - for me anyway and yes I'm not typical of most in this scene here.

With reference to the thread above my reason for posting is to correct misinformation regarding data that I deal with on a daily basis, it's not a weird stab at APR (who believe it or not I would certainly rate well above some other vendors here without question and I'm happy to go in that that if need be) its just that I hate seeing information from very sophisticated machines being manipulated in order to sell products - That is just BS IMO. Be realistic claim consistent 210 atw and I can't deny it, claim something that is beyond the capabilities of the K04 with that hardware and fuel and I"m sorry somebody just has to raise a response... but no one here bats an eyelid. I don't enjoy it at all but make no apologies either because its reality. I've said it before in other threads try this stuff on a jap tuning forum and you'd be shot down in technical flames.

WSID works well for most of our customers

Not our dyno, so no idea - as mentioned, it was a VW / Audi dyno day from Adelaide - that's several thousand km's away from us. Are you saying that a Mainline operator can fudge figures?



So that's a race car with WMI injection? We are talking about street legal cars I thought (based on the original poster) that run 98 ron & have legal injection & emission systems. If the Mainlines can be fudged as you imply above - how do we know about the ones you show?

You've missed the point I was trying to make. If you look at the header in any of these you can see the parameters used during the run. If you up the ramp rate so the run is completed in a shorter time then the load expericenced is much less and the top end of the run typically reads quite a bit higher. If you load it up - longer time for the dyno pull if you like, then the load on the car is much greater but the results will show how well it responds to this. I've seen some operators in WA use 20kmph/sec ramps which is ridiculous . With the DD dynos its even worse unless they use shootout mode to lock the operator out of some settings but thats another story. Typically with all the GTI's and Golf R's A3s' S3's whatever you would use a 10kmph/sec ramp or lower, a big turbo drag car OK use a higher setting for a shorter run but not these.

Yes that 225 car is not street legal officer but it's showing you what the K04 will do when maxed out at the top end and with WMI you've actually modified the BSFC of the engine so its more efficient. It does spin all 4 atw though and also has antilag ....my crystal ball says an 11 second quarter for the heavier S3 is no problem - not unlike what you would expect that similarly powered R in SA to do if the figures above are to be taken as gospel

Not having a go at you Parso. When talking tunes it's like groundhog day.

Forget all these guys and go a Spectune! :p

Sounds something I would like to have at this stage.

will save the CAI and exhaust change for the later. Do you suggest the rail valve needs to be changed at the same time with the HPFP?

CHeerS!

If your going with a custom tune then there is probably benefits to the Rail valve. The tune I have does not require the rail valve upgrade. So if your thinking of going APR (which is what I have) you don't need the rail valve. (well as far as I know anyway)

PS. There is no harm in having the valve and getting the APR tune. My car has the valve and it has no ill effects on the performance or reliability.

[Guy_H]

Yes, the Dyno's are not any form of reliable numbers to be banked on.

We just spent 2 days with the Mainline boys last week at a big press event & it very successfully demonstrated how you could remove between 30 & 120kw's from a Mainline Dyno figure.

It was an interesting exercise with 23 cars varying from 1.6l Turbo to 7.0 litre supercharged (and V12 Normally aspirated), in FWD, AWD & RWD formats. Power figures varied between 15 & 120kw's different to competitors own dyno's with different setups.

To the OP - the offer still stands if you wish to help out in a comparison.

Talk about groundhog day.

Yes well I think we picked the two most controversial topics and bundled them together into 1 thread:

1)ECU Tuning
2)Dyno performance

On a side note that Golf R that was mentioned above is heading back on the Dyno this weekend: SA Dyno Day II - 8am Saturday 24th May

There will be a couple of Mk6 Golf R's running along with an Ed 35, 2 x Sciroccos, 2 x Eos (not 1 but 2!!!!) and a bunch of other cars.

The best thing about these dyno days is that you get every car run back to back on the same dyno so you get some real world comparative results. Absolute dyno values are so variable between dynos that they're not really worth the paper they're printed on.

The only worthwhile dyno data is when you run on the same dyno and the only thing you change is the car (or mods on it).

Otherwise 1/4 mile times are good as it's pretty hard to fudge them.
