Ar qualitativamente è migliore..............................come rapporto qualità prezzo io straconsiglio i VK Motorwerks, la resa è stupefacente e sono abbastanza precisi oltre che di ottima fattura :wink:

cmq imho uno vale l'altro...................anche se ripeto gli AR sono il top :wink:

 

ma cosa mi hai messo in testa... porca costano meno della metà... se mi dici che sono perfetti sono miei...

 

vedo che c'è anche l'ic della vk motorwerks ed ha anche un prezzo eccezionale,che ne pensate?potrei fare la combo...che ne pensi Fabio?

 

le recensioni sono ottime :wink:

unica cosa che vi consiglio prima di acquistare dal sito contattate via Pm Vince.........................per la disponibilità dei pezzi :wink:

che vuol dire?

 

che al contrario del bt non è in grado di leggere tutti gli errori ma solo di cancellarli

 

aaah, ora ho capito cosa intendevi!

si qui ti do raggione!

 

Cosa vuoi che ne pensi. Boh... Io non sono in grado di esprimere un parere tecnico su IC e DP mi affido a voi e a te. Poi se ho problemi vi sputtano in mondovisione...

Tu dimmi solo a chi devo mandare la mail per il preventivo e io agisco.

 

procede

Lo so che qualcuno l'ha gia' scritto ma non ho trovato nulla.

Il procede V3 rev 2 e' upgradabile a V4?

Mi dite?

Grazie

 

non sono esperto di procede ma mi sento di dirti di si...almeno credo:wink:

 

yes sir! ;-)

Update sui turbo Stage 2 della Turbo Dynamics che mi stanno facendo in questo momento .

Le specifiche dei turbo:

the turbine wheel is 2mm bigger than standard

and the compressor wheel is 56mm and 42mm as opposed to 46mm and 35.5mm.

Mi sa che saro il secondo al mondo a metterli su, sembrano promettere MOLTO bene:

As some of you will know, my car has now been running successfully with the Stage 2 turbo upgrade and has covered 2000 miles since installation

I'll talk about the results first, as that's what everyone wants to read mainly! The installation procedure will follow in the next post...

The car has been on a long run over to Germany, completed 300 hard and fast miles of the Nurburgring, sat at 160mph on the autobahn for dozens of miles, sat in bumper-to-bumper traffic, and I have to say so far it has been an utter dream. It is quick, seriously seriously quick. I chased a superbike on the autobahn (with RagingKileak watching on from inside the M3 behind me) and when the biker gunned it at 110mph, I changed down to 4th, pinned the throttle, and stayed the exact same distance away from him all the way to beyond 180mph. The car was still pulling hard but traffic stopped any further progress. Fuel consumption isn't so good at those speeds - I registered 8.6mpg (UK) at 180mph!!

It is very docile when driving around town - part throttle response is excellent, with very little apparent lag. The response for the first 2000 revs is sharp yet normal and linear, although you get the sense of something muscular building from within the engine. Over 2000 revs, the mid-range is astonishingly strong and goes utterly mental at 4000 revs. Power runs all the way to redline, and the next gear change just places the revs right in the meatiest part of the torque band. I wheelspin in 4th gear easily and if you don't have a LSD installed, you have absolutely no chance of making decent progress. There is so much power that it would completely overwhelm the DSC system.

The car on the Nurburgring was a revelation. The rate at which my car overtakes a race-prepped Porsche 997 GT3 RS going uphill after Breidscheid (second entrance on the 'Ring) is astonishing. This part of the circuit is notoriously power-sapping and demands as much torque as possible from an engine. The owner of a Porsche 996 GT2 who had a passenger lap with me said that my car doesn't feel as explosive as a GT2 in a straight line as it is actually more linear in its power delivery, but judging by the speedo my car was significantly faster than his GT2. The linear power delivery is very much a key to how well the car drives with the new turbos - it's supremely easy to judge where the power comes in and consequently apply the power to the tarmac without lurid tail slides.

A few forum members have had the chance to experience the upgraded car over the Easter and I'm sure they'll be along to comment shortly.

With the latest round of supporting mods, including a secondary oil cooler from AR Design and a high-spec Setrab core replacing the main oil cooler behind the bumper, the engine reached a maximum oil temperature of 125 degrees celsius after hot-lapping around the 'Ring. This was a spectacular result and in no small part down to the efficiency and placement of AR Design's oil cooler. There were ZERO limp modes, no strange fuel surges, no dodgy starts. 100% reliable. At a constant 160mph the oil temperature stayed at 120 degrees. At normal autobahn speeds (100mph) the oil temperature stays at 110 degrees

I have decided to move away from a flash-based tune for the moment and asked Shiv @ Procede to send me his latest V4 device. Thanks to Shiv and his guys for managing to ship me a new unit from the States to the UK in two days flat The reason why I've gone to Procede is mainly due to the customer-base in the States - there are so many people interested in the turbos from over there, a lot of which are using Procede, that I wanted to see how the car would run in its new configuration with the external tuning box.

Shiv created a basic map at 15psi for me to run with, and it is this map that I've done all the testing on. It's ONLY 15psi!! I had planned to run 17psi as my normal tune, but judging by how fast the car is at the moment, I can't begin to think how quick it will be at 17psi

The bottom line is this -

• The Stage 2 turbos are EPIC and a considerable improvement over the Stage 1 modifications
  
• There is immensely strong power all throughout the rev range right up to the red line
  
• Properly tuned, the car feels every bit as normal to drive as a regular car, just with a HUGE amount more power in reserve
  
• It's been 100% reliable so far
  
• They are expensive, but you get what you pay for
  
• Do not underestimate the benefit of retaining all cooling lines - upgrading turbos without using the water lines is an utter disaster waiting to happen
  

However, there are some things that anyone considering Stage 2 turbos need to be aware of, and you should read my next post on the installation aspects

• You need new oil and water lines
  
• Installation is a BITCH
  
• You NEED NEED NEED supporting mods - oil cooler, intercooler
  
• You must reduce the backpressure in the exhaust - downpipes, freeflow exhausts etc
  
• You must use the highest quality oil possible that resists degradation at high temperatures - Silkolene ProS 5W-40 is the ideal oil
  
• Most importantly, you need the most competent workshop team possible. You simply cannot install these using the local mechanic from down the road, because things will go wrong, I guarantee it!
  

Nel frattempo sto mettendo su OCC AR, rifacendo assetto con camber plates DINAN , montaggio BMW performance Wheel e BMW performance carbon interior.

Il problema di missfires che avevo era dovuto alle Candele... non avevano neanche 10.000 km quindi cambiatele spesso se fate i cretini continuamente come faccio io

Ho ordinato le candele della mini cooper S turbo che sono un grado piu fredde, 3 persone le usano su e90post e sembra vadano molto bene senza missfires.

Modello NGK ilzkbr7a-8g

Spark Plug - Laser Iridium

Product Line: NGK

Part Number: NGK 5992

Attributes Spark Plug Hex Size : 14 mm

Spark Plug Reach : 26.5 mm

Spark Plug Seat Type : Gasket

Spark Plug Thread Size : 12 mm

Ho abbandonato progetto candele GTR visto che il mio mecca me le ha sconsigliate dopo un po di ricerca (sembra che siano piu calde...)

grazie 1000:wink:

Comunque se mi succede li denuncio.

Tutelarsi è loro diritto,quindi se mi beccano accetto il fatto di perdere la garanzia.... mettermi fuori uso volontariamente la macchina e farmi ripagare la riparazione si chiama truffa,per cui.....
