German850R

Not the nicest one in the world but affordable: https://www.ebay.de/itm/Zylinderkopf-B5254T2-154KW-291Tkm-Volvo-XC-90-2-5T-AWD-XC90-06-1043-076/311983651813?hash=item48a3acbbe5:g:iGUAAOSwh9hZ6JU9:rk:20:pf:0

I already have one for the 7064 somewhere here under showroom. I can make a new one once I start on the 7670. Right now, the car is waiting for the body shop slot in January. Needs some rust removal and conservation. And engine bay paint ;)

One of the best turbos for this application. Love mine, but am upgrading to EFR 7670 and a custom spaghettifold.

Facebook and Youtube ;)

Thanks to you crazy guys I also bought a V40 T4 ;). Will pick it up next week and then will see what I got myself into...

Awesome numbers. I have to build a new engine this year and am considering dartons as well.

They go to the TPS and idle control valve. Installation is plug and play. All you need to find is a 12V source, so ignition coil or so. There is some adjustments you need to do at the device but Maarten includes a good manual with it.

Might be. I can check in the car if I find something. But if they are not making it anymore, there is no point ;)

Not exactly. It has been put in many years ago. I remember it being Bosch or maybe Hella.

Maybe related to this. I also happen to own a Saab 9-5 Aero as a DD and the PO installed a Bosch aftermarket rain sensor relais. It comes with a rain sensor which you put somewhere in the area of your inside rear view mirror and the relais plugs into the stock relais socket. It works great actually. So I might be doing this to my Volvo 850 as well, tbh.

Better race it in a real simulation like Iracing or Assetto Corsa then ;). I live only 2h from Spa but have never been unfortunately. Maybe because it always rains there :D

It moves... Do you have a chance to measure the acceleration with a Racelogic vbox, Driftbox, Performance box? 60-130?

Sure, helps tuning a lot ;). I can offer you a place to stay as a "road tuning base" with great access to good motorways ;). From our new place we have 3 great motorways within 10min of driving

Maybe I have a German view on it. Our cars see a significantly higher load collective due to our (few remaining) limit-free motorways. So, for us a car with twice the original power output reaching more than say 50000km with a certain setup is quite uncommon. Of course, there are cars which last longer than that, but that would be the exception.

Is it just me who thinks that 40k miles or 60k km on a build like that which went through a lot of tuning iterations and certainly some level of abuse is actually quite OK?
