Most chip tuning software will boost you to around 370HP and 670 torque, that's about all the stock pwoertrain can handle. I'm sure you could up the boost but with turbos costing $2 grand a piece and the need to remove the engine to replace them has likely limited the aftermarket.

 

Do we know for sure what the differences between the standard V10 and the R50 are? I feel like I heard that it was basically just software changes and that the major components were the same. If that's true I wouldn't go much further than a software tune, I'm confident VW knows what they are doing lol.

 

Here in the UK someone had his V10 remapped and dyno tested today - 401 bhp and 1020 nm torque!

Everything else, apart from new flat panel air filters, was left as standard.

It usually costs £300-£500 here.

 

Yeah, chipping makes a huge difference. Before going nuts trying to find what's available, just get a good tune done to it, its quite satisfying. I got mine done by Upsolute, but others on here have O.Ct. good reviews for both those chips.

 

I'm talking "remap" rather than "chipping" - they are two very different things as was pointed out to me recently when I persisted in using the now old fashioned [and unnecessary] "chipping"!

 

I hope those stock turbo's are operating within their efficiency range at those boost levels!

If I owned a V10TDI(but don't), you can be damn sure that I would have figured out exactly what kind of turbo units I had. Meaning 1st and foremost their compressor efficiency, compressor size, then onto turbine size, A/R ratio, etc. This would have given me the back bone to understand what really is going on, thus providing an accurate idea of what the thresholds would be, and where to proceed from there should one seek that delicious =P~ adventure.

 

well I'm using the term interchangably...nobody physically "chips" a V10, they upload new software into the two ECUs via the diagnostic port. it takes less than 2 minutes to reflash.

 

They are honeywell variable vane turbos...the ECU board on each one of them controls the angle of the blade. I've got the honeywell model number written down somewhere, I'll find it if someone believes they can help further the discussion?

 

it would actually. it would be a great deal of help to know where the restriction is on this thing.

 

I took an Ebay pair to to my turbo guy to see what he could do with them. He was not very optimistic but he did say they the T15 compressor wheels could be upgraded to T17 wheels. He also pointed out that most shops wont even touch a VNT assembly I posted pics of the turbos dissasembled here... Now which thread were those in...

i did come across those pictures. I just find it amazing that with all the companies out there nobody makes a simple manifold or turbo upgrade for these things. I wonder how much would be gained by the T17 housing.

 

Heck just drop a Hemi in it... Sorry I digressed

Why would I want the DECREASE in power???
