Hi the car sounds very good now, I only have a 210bhp D5 but I do get 50mpg and that feels fast, so another 140 on top of that must be amazing,
when you have it on the dyno, please post the read out,
Dave

You will have shed loads of torque though.
Likely next Friday.
yes 440nm last tested may be a bit higher now with 2 1/2" free flow ex pipe,
I can not go to high as it is a 2002 163, the 185 have a larger clutch,
I did think the dmf was on its way out as I was getting some clonking , but I changed the engine mount under the front pulley, and all is now good, you could see on the subframe were the mount had been hitting it,
your torque will be higher than mine now, it will be good to see, were will you be taking it
surrey rolling road ?
Thanks Dave
How doe nm compared to ft/lbs?
325ft/lbs,
Dave
Ah OK same as mine pre the cloning of the ecu to good ecu. So yep should be more.
Mind Diesels will give those torque numbers from much lower in rev range.
Seem to be doing 2/3's of mile in it at the moment towing (seems a waste but it is damn good at it).
but your torque keeps coming, the VVT helps your engine, mine starts dropping off at 2800rpm,
Dave
All a trade off you have less performance but a lot better mpg!!
yes it is a big trade off, I would love a R
but I do like the mpg of the D5,
Dave
So after a few weeks with the car, during it felt way better, but still not as great as I'd expected(!). Got to the rollers (all my car go same rollers some comparing eggs withs eggs and it is Dastek which is best kind from speaking to people on this).
Up from 293bhp to 310bhp and 325ft/lbs to 345ft/lbs, and drive a lot better. But 310 is still pretty lame considering the amount of boost that is supposed dialled in via the remap. Mind the torque gain is good. From when I bought it to now is a huge improvement. But still not what I was expecting http://www.southwestincartech.co.uk/.../volvo_v70.htm . These numbers are with the std exhaust on the car not the big bore 3" cat back thing I had made. So when factoring that in (IPD clone basically and they say good for 15-16bhp on stock). So something still amiss, even though torque is really good.
Basically the chap running the car on Dyno was saying it felt like the boost is dropping the more revs you give it and this seem to show in that it just flat lines at just over 5k as far as power is concerned all the way past 6.
He felt some of it could be down to the variable vane turbo these cars have where they have trouble holding boost with the revs, but he does think it should be better than it is.
Will have to log the boost with Anthony (ad get my Vida work - maybe!!!!!!!!!!).
If you drive it knowing what the dyno curves look like it is damned fast on a B or A road but on an M-Way you can tell it is still running out of puff much past 5.
Pity there is no one down here (Woking) that I could just give it to. Was some guy near Haslemere but a complete tool when rung and explained had had remap elsewhere and felt car not right, basically told me to bugger off..... (great business acumen).
And taking to Shemtek is a bit of and extreme far to go, at least for now. I'm feeling it is going to be something fairly simple but how to work it ok. So got the torque I was expecting (as developed low down rev range, but not really taken up with big power as you keep the revs rising!).
Bloody great chassis though. And has to be faster than a std one. Did I say how crap it was when I got it.................
Hi I don't think that they have a variable vane turbo , a lot of people have problems with the recirculation valve on the turbo leaking, have you not logged the boost to see what it is doing,
is the air filter good,
Dave
also is the MAF working correctly,
Is the intercooler ok, no leaks,
Dave
Hi I know that you don't want to run a boost gauge,
why don't you go on ebay and get a cheap boost/pressure gauge just for testing,
Dave
I think you are right on the Variable vane - Anthony said as much on a txt.
Will try to get recirculation valve on the turbo checked.
Logging when can get to Anthony's (next week most likely), suggested we check the wastegate setting, and hopefully get my Vida sorted.
MAF I think is fine, cleaned several times.
No leaks from anywhere on car inc Intercooler.
I'll discuss the boost gauge thing with Anthony. But I have not got time or inclination to fit a boost gauge (most look naff to as no RHD nice pod I can find - but more about the fitting - looks complicated (remember I love carbs.....!).
Does make you wonder just how long what ever this daft base issue we eventually find on the car has been like it, I'm guessing half its life or more!
Once we have found the base issue or maybe to fix it, what about these?

That Turbo look small in the picture!
Also in here https://shop.mambatek.com/Adjustable...0-023-0192.htm
on the image about rod length vs boost pressure. What does all this mean if the boost of the remap has been set to about 1.5-1.55 bar (~22psi).
I never changed any springs or put one of these on my old T5 when mapped at 155k miles and it was totally transformed from pre to post remap.
Hi
with the waste gate actuator the only time that you will need to change it is if you are trying to make higher boost then the Volvo one can manage,
or the turbos standard one can get blown open by the boost of the turbo as the actuator spring tension of the waste gate can not hold the turbos waste gate valve closed,
but you don't want to have to much tension as your cars ECU controls a turbo control valve (another part to check) so it can control boost at all revs and load,
a to large waste gate actuator will hold the valve closed and only open at full boost,
like I say check/change the turbo control valve, as they can leak or stick as it is a solenoid, and the plunger opens and closes to direct boost pressure to the waste gate actuator or back in to the intake/atmosphere ,
this it why you need to see your boost pressure, and also know what it should be, ask the man that mapped it to tell you what boost pressure should be at high boost/load,
and at lower revs, he should tell you this, unless he did not write the map and got a file writing company to write/mod the original BIN file from the ecu, , so please ask him, so you will know, like you say it is most likely 21-22 psi max boost,
as you say that you have no leaks, if you see the boost dropping off to much it could b the turbo boost blowing it own waste gate valve open, waste gate actuator gone week or the pre-load not set correct, use a mityvac pump to check this, look at ipd/youtube on how to do this, or the ecu controlled turbo control valve,
Dave
To see if the turbo boost is blowing the waste gate valve open is to disconnect the boost/vac pipe that fits on the actuator ,block this pipe off, and see if the max boost is higher than it is normally and does not drop of to fast, but you will need to keep a very good eye on the boost pressure and don't let it clime to high, it will go up very fast as there is no boost control,
all standard turbo's boot will drop of as the turbo can only make so much air, that is why people use hybrid turbos,
Dave
Thanks Dave. Did think if the T5 never needed any of that stuff changing and a remap transformed it, then the R should not need it.
Changed the Boost Solenoid not too long back.
Ok will ask mapper. He wrote it.
Well I have no leaks in cooling side. Dyno chaps did say maybe a boost leank, but then went on to say, you likely hear it and the torque low down being so good implies it is at least holding in first half of rev range.
"if you see the boost dropping off to much it could b the turbo boost blowing it own waste gate valve open, waste gate actuator gone week or the pre-load not set correct, use a mityvac pump to check this, look at ipd/youtube on how to do this, or the ecu controlled turbo control valve"
If Boost solenoid new, not likely to be that, then like you say could be the waste gate actuator gone week or the pre-load not set correct.
Will send this thread to mapper and get with Anthony for logging next week.
So there is clearly something not right, somewhere, I don't need to rush out and get a Hybrid turbo!! Well not yet :)
Std one should hold boost through rev range, as per my T5.
