Cheap & easy brake cooling mod

spearfish25

I like the simple setup and truly hope it's helpful. Just need a good way to quantify the effect. Do you have a grill radar temp gun? It could help with tracking your rotor and caliper temps, and hopefully we'll see a drop with this setup.

As for ice mode, it's an inherent issue with the ABS system. The ice mode thread dives deeply into this topic, but in short, differential wheel speeds or very abrupt brake application cause a drop in braking force and the perception that you're sliding on ice. It's not temp related but can be exacerbated by pad compound. I've seen many many explanations but few solutions. Guys with other car brands have swapped in a race version of their ABS computer (ie from the Corvette GT2 race team for $$$$) with resolution of the problem. The cheap bandaid fix is to briefly and rapidly release the brake and then reapply which will clear the problem. Getting your foot to lift off the brakes when you want them to work 100% is not an easy task though.

Sprearship,
Tanks for the clarification. I will report on rotor temps from my tracking session mid-May. As suggested by Kenchan, i'll take temps with blocked and open air vents.

hey philipp- how did the experiment turn out?

Philipp

lol... Sorry Spearfish for the misspell. I should definitely remove the "auto spelling" option from the ipad…

Kenchan, lapping session is mid-May. I'll report back.

Your guess was right...

Let's say it wasn't conclusive....




Group,

Here's some feedback on the cooling effects of this mod. Over the week-end, i had my first lapping event at the Mont-Tremblant circuit. After each 30 minute lapping session, i recorded the front rotors temps with a digital laser reader.

Voila the results with open air ducs and blocked air ducs:

Morning runs:
- 8h30-9h00 (open air ducs) Left Rotor: 488F & Right rotor: 411F
- 9h30-10h00 (open air ducs) LR: 501F & RR: 440F
- 10h30-11h00 (blocked air ducs) LR: 490F & RR: 434F

Afternon runs:
- 13h00-13h30 (open air ducs) LR: 535F & 503F
- 14h00-14h30 (blocked air ducs) LR: 511F & 488F
I stopped recording rotor temps after this point...

Track notes:
- This great track has a majority of right turns;
- The front left wheel is receiving the most stress;
- At the end of the straight line i was reaching 138MPH (hoping for some serious air to warned the brakes).

Conclusions:
Based on those numbers, i have to conclude that this mod is worthless...
Even worst, it seems that the centrifude force of the wheel spinning does a better job in keeping the temp down then having the air ducs.

Can anyone put a light into these findings?

Thanks,



Phil
