Thermo fans on intercoolers

So what do you reckon? Thermo fan on a intercooler.

I've just got the stock cooler on my GTST33 and I know they have problems with heat soak when on boost for extended periods. As far as I can see a thermo fan could completly eliminate this problem. As well as helping the convection cooling of the core and therefore further reducing the air charge temperature.

Also, if you have got a aftermarket FMIC in front of the radiator (or a GTR), a thermo fan could help prevent overheating problems by forcing more air through the cooler onto the airconditioning radiator and engine ratiator.

Just a 12inch davies craig (or similar) would be sweet.

Next prob would be how to switch it, it would be perfect to have it on when on boost and a few second delay after you come off boost, so maybe a thermo switch in the air flow on the hot side of he cooler with some sort of delay for the switch off.

Prolly not much of an advantage on a aftermarket cooler, on cars I have driven with decent coolers, the outlet side (cold side) of the coolers are supprisingly cool even after a flogging. But like I said may still be worth it for the overall heat rejection of the engine, or on the small stock cooler to reduce heat soak.

Any ideas?

i also played with the idea but went for the FMIC in the end

i actually tried to mount one in front of my trannie cooler but it wouldn't fit :D

i used a second-hand thermo fan from a mate's TX% turbo so try to source a cheaper fan first

i was going to simply wire it to a switch on the dash so i could just turn it on after/during a spirited drive

Interestingly, Nissan actually implemented this idea on the R31 GTS-R.

I would assume it was to force air through the cooler onto the radiator as the GTS-R has a large front mount covering the radiator.

It is an approx. 10 inch fan mounted on the front drivers side of the cooler.

If you sit in traffic for extended periods on a regular basis i think it could be a good idea, but otherwise i'd take waterspray but as effective as it is you still need airflow, so ideally you'd have BOTH on a FMIC :P

In summary, i'd go with a simple FMIC, or if you want to remain stock looking setup a waterspray (remember my traffic exception).

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
