I have been trying to get a grip on my fuel usage over the last couple of weeks as I fixed my fuel guage recently.

Running 8psi of boost on a 1.6 engine I'm getting 150miles a tank, or 25.5mpg. Same as my DD so I'm happy enough with that!

Can't complain at that.....not like the roadster is a super slippery shape!

Where's your drain plug from? And what's the spec? Trying to find something on ebay but failing.

Thanks

I recycled the original drain plug. Chopped it out with an angle grinder and turned it down on the lathe.

The guy that welded mine up hated it and said never again.

Added some bonnet vents. With the turbo my normal running temps are 103-110c even with a full mx5 reroute out the back so hopefully these will help a bit.

So THATS what that rattle was....



Glad it only took 45 mins to change.

If you get a china manifold, get a good quality pressed stainless gasket for it. The China one was aluminum is seems.

I'll have to buy a fitting then, I wish I had a lathe.

What car is the rad and intercooler from? They look a neat solution.

190E?

"The Mercedes 190E radiator that many of the Haynes Roadster guys use has an oil cooler built in.

Its upside down in those ebay pictures, the red caps are on the oil filter in/out.

Have you thought about waterless coolant or maybe removing the thermostat? These are things I'm considering.

Yeah the rad is a 190E radiator. The core is exactly the same size as the intercooler. I have ducting in the nose too so that air cant go around the intercooler.

My temps still run at upto 110c. I have a full reroute in place and the fan switch is at the thermostat. In traffic the fan will come on and bring it back down to 102. It seems my fan switch actually comes on at 110 and off at 102 rather than 97/92 as its supposed to. Its new too.

Im going to try running the fan off the ECU for a while at a lower temp to see if that helps but It will probably just end up with the fan on permanently. If not ill try without the thermostat to see if it overcools then but really its when im going 70-80mph on the motorway im getting the most heat into the engine, its sitting at 4000 rpm so whenever you apply some throttle its into boost.

I think the radiator just isnt removing enough heat so I have a spare 190 radiator with a hole in it and Im thinking of sending that off to have an aluminium twin or tripple core copy made up if nothing else helps.
