Ex850R;12713 wroteOne thing i found in ,y search was that cryogenic treating of all moving parts makes for a smoother and longer lasting unit be it gearbox , including autos and engines and diffs. It normalises the structure of the metal ( look at my crap analagy , i learnt all that stuff way back when!!) There are places to do it in capital cities , i never got any quptes though.
I think then that you will now be spending at least $20,000 as the cost estimate is usually a third or quarter of what you actually spend!
Maybe ask Hussain about TTUsb , you will be severely limited by what Lucky can do from afar , if you start off with tirboTunerUsb , Hussain and Johann can help and Johann i think? has base maps for you to run as he has built up various tunes progressively getting more radical. You can then tune yourself vis the data logging and seatof pants or use a dynoo for some of it , you will always have a base map to switch to if you have the lptop in the car all the time during testing , TT gives you that option. Whereas ARD tunes whilst they can be done via the USB , need Lucky to know what and where and when and with those sorts of power figyres you are chasing you want the tuning done at home.... PM Hussain , i did the other day and have no fear about the power through the AWD or angle gear , he has had no problem , the only thing with the AWD Volvo system is it is critical to have all the same size and brand and tread tyres and they MUST be within 1.50mm (2/32?) in tread depth or damage can occur. The rear Viscous Coupling ( VC ) is silicon oil filled and as the heat builds up the plates mesh and take up drive locking up at high heat . I would go the 6 spd , i hated my 850R 5 speed around town with the dumb high first gear and big step up to second to stop wheelspin. The least you can do is get a Quaife , the STD R LSD is useless. The 6spd sratios should aleviate the ratio jump of 1-2 which on my R was only good on big open sweepers , too big a change for around The Great Ocean Road as it left me in no mans land or spinning wildly and believe me , there are no tyres to control it , i tried track tyres too...
I sit on the fence on water injection , if you have good fuel why are you putting a non burning substance in the mix? Just make it fuelled properly with proper tuning and proper fuel , water / meth maybe? I leave it to Johann and Hussein on that front as to do or not. Money best spent on other things i think as its not cheap!.
Yeah that is absolutely some next level stuff that I don't think I would need for the next decade or 2 when I start chasing a few thousand HP instead of a few hundred.. still I think its cool that the option is there, but if your getting that done your probably not doing the engine work yourself.. oh to be rich :)
Holy shit that is cool as fuck (I hope this site censors swearing) about the ttusb. That is something I have wanted for the last decade and was stoked when I had a car with obd2 instead of one as it had some computerised readouts.. I am definitely going to be doing A LOT of reading to catch up on this product then chase up the guys in the know you suggest.
Man.. I didn't know the AWD was so sensitive, mind you I don't find it hard to stick by those guidelines, but still..
Yeah about the water injection, I meant to say that I would always be running 50/50 water and meth, never more than 50% meth especially but preferably half n half. My worry or want for that matter, is that I make my setup run as cold as humanly possible, using the largest oversize intercooler & radiator as I can fit, water/meth injection, intake manifold spacer.. any other wacky idea to get air venting into the engine bay.. not so much for the power gain that comes with the cooler air, but the less heat in the engine to help with the durability of the parts so I can really abuse how much pressure I want to get out of the turbo especially.. I know there is a power increase and fuel economy maybe in running the water/meth but its really for me a great addition for engine cooling. I've seen a few cheap kits from good sources (some listed on this site) that end up being cheaper than an intercooler (not as a replacement for an intercooler mind you)
