Now we are getting into the warmer parts of the year, im looking at engine cooling. Has anyone previously removed their std fan and clutch only to replace it with a complete electric unit.

I was looing at the Davis Craig electric water pumps and electric fans. I imagine your car would run cooler on track and eliminate a lot of load placed on the crank by pulleys/cfan clutch. Not to mention i imagine the whole setup would be lighter.

With minimal amp draw you can even set these things up to continue to circulate coolant thru your engine after you have shut it down!

Plus looking at engine bays of track cars, big hp cars you never seem to see the factory fan and clutch. My car though reasonably stock was getting some serious heat soak at the track.

Yes, I've put a DC thermo fan (DCSL14) on mt GTS4. It is triggered by the A/C fan which in turn is triggered by the thermal switch in the bottom tank of the radiator.

I find it turns on at not much above normal operating temp. On the track, I've found that the engine actually overheats quite significantly. This may be due to the FMIC blocking air to the radiator, rather than the fan situation. I suspect I am going to have to get a couple of extra cores fitted for summer. And because of space restrictions, the fan has to be mounted and operated as a 'draw-through' rather than the more efficient 'blow-through'.

The power gains are apparently minimal.

      Mistakes were made, my R34 Story

      Yea the photos aren't the best. When I was pulling the bumper and headlights out there was a bodyshop guy looking on for it, there is a slight bend behind where the passenger headlight is, but we're talking a few MM and there is a little bit of a bend for the reo. That said it's supposedly well within the "Drill a hole in it and pull it out with a slide hammer to be close enough" and be on our way. The other option is to buy a GTR reo for the GTR bumper bits but this is a $2000+ fix for something Mr Hammer can probably do 99% of the job for and everything will/can line up pretty closely-to-good-enough.

      That's a write off for sure... Part out? 😛 I kid. It looks like the rad support has a minor minor bend in it too where the rep support sits near. Could just be the photos (and me not wearing my glasses right now). Worst case is you can buy a new radiator support, have it swapped over, and leave the car in paint jail for 12 to 18 months while you build the motor to handle twin turbos or a Harrop SC...

      It seems the definition of "Gregging" something might need to be expanded?

      R32 GTR - Where to begin

      By GTSBoy · Posted

      This is why I suggested that there is really nothing that can safely be done in the engine bay at this budget level. Just the work to reassure yourself that the engine won't instantly crap itself the moment the boost gets turned up will wear out the piggy bank long before the first turbo gets installed. Spend $10k and still not have any extra performance? My tip is a version of our standard advice from 15 years ago about buying a GTR, which is not to buy one unless you can afford to buy two. The new version is not to modify a GTR unless you have all the funds required to do it all at once, properly, and enough to rebuild it after it blows up.

      Oh, I forgot to mention this before.  It is accepted that your taking on risk buy turning up the power on a 30 year old stock motor. You can lower the risk with the ECU engine protection, but this is more money on sensors. CAN wideband, oil temp, oil pressure, coolant pressure, fuel pressure, air temp, etc. It adds up quick.  I am a huge fan of running all of the engine protection the ECU offers. You'll have to decide for yourself how you want the engine protection setup and what you think is worth monitoring.
