I would go that 10 row cooler if it is not too much work. 10 row is better than 0 row
CSF upgrade will probably have some benefits in conjunction with oil cooler. People don’t see benefits as they want to avoid installing oil cooler. IMO at this altitude oil cooler is reality people have to accept.
copy. just saw over the weekend that someone has a brand new one up for sale on one of the mk7 forums for a good deal so may pick it up. The other downside of this kit is they use a proprietary stainless filter. https://www.ecstuning.com/b-racingl...-oil-filter-for-vwr18g700-only/vwr180001~vwr/
They recommend replacing every oil change which at $60 a pop is crazy. I'll probably buy a second one and just clean and re-use and swap each oil change
Haven't seen anyone use Setrab's for the Auxiliary coolers yet. For oil coolers, yes, but not on the DSG & Aux coolers on the Golf Rs. Yes, have seen the WaterWetter positive feedback. Definitely worth trying as wellCSF aux coolers are better than OE ones, but not quite as good as the bigger Setrab units. However, they are much easier to install as noted. Pay to play I suppose. Jury still out on coolant radiator unless dedicated racing, lots getting good results with Water Wetter/h2o mix vs. standard coolant but YMMV.
P/W is injector pulse width or injector "window". Obviously when the read goes lean, the tune programming opens up the P/W first to compensate until there is rail pressure drop. Then depending on who does your tune, and what fueling mods you have, more fuel is signaled by the low side pump modulator/controller to deliver what is needed to prevent high side drop. All stacks up to more fuel entering the combustion chamber and under F/I, gets into the oil. Yes, EtOH volitizes through heat/use, but not before film can be compromised. Residuals can tax the reserve alkalinity of most oils and why short intervals are recommended. Or use an oil that deals with alcohol fuels well. RLI anyone?
Thanks for the clarification on the injector window acronym. I'll have to review my logs again and see if that data is detailed. There is some customization with the Cobb Accessport so I might be able to add that in (assuming not already on my logs) if it's an available field/data point.
Equilibrium Tuning is my tuner. I have pretty much everything on the fueling side (short of converting to MPI). I didn't want to risk any lack of fueling whatsoever since that obviously can be catastrophic. I have upgraded HPFP(Autotech), LPFP (Pagparts 535 Walbro) and I upgraded the stock fuel controller to a Torqbyte PM4.
