I had 940 on mine also while under load high rpm, but yes i dont think it very good in long term. Didnt happen anything in 25000km tough and new owner now drives even harder. What is your EOI @5krpm?

I have 30 deg. advance SOI and just under 1ms duration full throttle.

Went for a more or less final Insoric Power Measurement today after bumping up fuel to max ~90mg/str and 2.1bar boost. Weight about 2007Kg with 2 people in the car.

With good cold dry weather today hit 343.4HP and 622.7NM. The power was probably a bit more wider to 5000rpm but I did not take it all the way to the rev limiter.

The clutch is sort of at the limit, especially with the cold weather. But car is running great. I will upgrade the clutch.

I also did a 100-200kmh measurement with VCDS and got another second less going to 90mg/str from 86mg/str. You really feel a difference between 86mg/str and 90mg/str. 90mg/str really feels solid. If you consider 13.xx secs for 100-200kmh and losing almost 1 sec shifting from 4th to 5th and the car being almost 2 tons. Then upper 12s is not bad.

I upgraded the boost gauge to Raid HP digital and to 3 bar since I am maxing out at 2.2bar. Much, much better to have digital gauges.

GTB2260VK what a turbo!!!

How accurate is this method of measuring compared to well calibrated non optimistic dyno?

I am not an expert on Dynos and with all the endless dyno fudge factor discussions I am very glad there is a straight forward, transparent and uniform method that can be used anywhere and the evaluation is done in real world on the road measurement. Potentially you could end dyno discussions. Of course you can cheat with this device also, but there is no unintentional error. Essentially you need a reasonable flat road section (can drive both ways to check accuracy and use for correction), accurate weight of the vehicle. I checked 100Kg off gives 20HP error. Basically you floor it to rev limiter and let it roll. The sensor on the wheel very very very accurately at a high rate of sampling captures the vehicle speed vs time using an accurate measurement of the tire diameter. When we checked the log, it even showed up the speedo error at low speeds - rpm vs speed. After acceleration the roll down calculates the losses including wind resistance etc. The rest is in the physics formulas. It is a simple but great idea that a Prof in Switzerland came up with for precision. It is now widespread in Germany. The consensus is if it is done correctly it is very accurate. The key is to record the speed accurately at high sampling. There is a youtube video on the method (Insoric) from the Prof but is in German. The only time I can see it being an issue is if you have traction loss due to too much power - it will mess up the signature, whereas on the dyno you strap down etc. and prevent slip but in reality you would have traction loss anyway on the road - i.e. it is the power being transferred to the pavement - real world power. Unfortunately the price is quite high else i would buy the device. It is a fairly inexpensive device but like all the tuning stuff, they ask for a lot of money ~4000-5000€.

Mac, now i need a clutch upgrade. Any recommendations?

I hear the perfexpert also gives good results when calibrated well. Weight of the car, frontal section area and CX play an important role.
Dynomet is another similar tool to Insoric, a guy in poland tested it different time VS Vtech dyno and he got pretty similar results.
Price about 3000€

Got the clutch upgrade done. Used the Sachs Race Engineering (SRE) Pressure Plate and the SRE Organic Disc without springs. I decided not to go with an SMF at this point - figured a bit smoother with the DMF, less noises and not going totally crazy on power. Goal is to hold 650NM-700NM. Also the SMFs are quite pricey. This setup is officially rated at 550NM but holding fine.

A bit grabby initially taking off in 1st and reverse is worse, also engine braking into 2nd some chatter, but even after 3 days it has gotten a lot better. As posts in the internet say after 500miles equivalent town running should be fine. The biting point is higher up on the pedal, extemely short travel distance, so shifts are quicker.

This time I got some local guys to do the job. I felt the tranny is too heavy to bench press or do in the 'driveway' as I have done in the past with the 4cyl. Young Serbian German chap opened up his own garage couple of years ago. Really knowledgeable, nice guy gave me a good price. One journeyman and one apprentice took 5 hours together.

Parts removed were: piece of the exhaust, axle joints, transmission crossbar, gear cables and connectors.

In summary I really want to thank all the eastern europeans (Poland, Estonia, Finland (not quite 'east' but kind of - lol), CZ, Bulgaria) who helped with this project giving tips on the tuning. Could not have come this far without their tips out of sheer generosity and solidarity.

Eddie, i can see you’re still on original brakes, are 320mm big enough to stop you ? I had same brakes on a c5 a6 before and 335mm on a c5 allroad and they were scary sometimes ! I moved to 8pot calipers after as the brakes did not inspire me with confidence after getting brake fade a couple of times !

You are right. I am on 321mm brakes and there is a 347mm system from gasser 3.0T etc which can be used. However a while ago I switched to Zimmermann Discs with holes and the braking improved alot. Before that as soon as I did high speed hard braking on the autobahn >200kmh the brake discs warped immediately. These ones are not bad actually, but something maybe to do when the weather gets better.
