Right with it's huge elevation changes. What's it matter? You're not even going to track this car anyway. |
I don't know if they're that functional, but I have ducts on my car.

I've gotta duct too. I'm doing the 11" corrado fronts and adding ducts. I'll see if that takes care of the heat issues before I drop some real coin on 2pc. rotors and wilwoods.
Hustler, looking forward to seeing what your AH-HA moment was. |

2.5" will be fine if everything is sealed properly.
Anyone that ever does a trackday should have duckting. It's cheap and easy and possibly the best mod you can do to your brakes short of bigbrakes. Do it! |
I don't dissagree with using ducting for the track, it's cheap and will lower the overall temps. I just think it's silly for Hustler to put them on his car.

Relax, kneegrowth. I'm fucking with you. You're worrying about the track for this car when it hasn't even seen the track, and based on the last week of posting may not, just seems like excuses to not take it to the track. If you're getting squishy pedal on the street your shit is broken. Flush your fluid with new stuff. |
Watercooled brakes... - Viper Alley - Dodge Viper Forum
See if the link works.... I suxa at this techo crap, but same principle as what's used in Europe with their big rig races on mountain courses. I still am a little apprehensive with water and some metals that tend to explode under conditions. |
I cut a 6" length of 2.5" exhaust pipe at a 45 degree angle into 2 even pieces, and then welded it to the stock dust shields. Picked up 6ft of 300 degree hose duct (the 650 degree hose is pricey as fuck, I'll step up if I melt what I bought), hose clamps to the pipe, route it under the radiator to the mouth, sip champagne when I'm thirstay, etc.

i bought 2.5" "brake hose" and radiator shrouding from bsr about an hour ago. Now I just need to weld some shit up, drop the top, holler back "money ain't a thang."

I overheated my brakes just driving in the Hill Country. I could definitely see it happening at MSR, especially on the 3.1 mi course. That sharp left turn at the bottom of the hill on the new course section (CCW, near the highway) would be interesting. I could see it impacting lap times overall for sure if you have to back off of aggressive braking to save the brakes.

It's not just how hard you brake, it's how often. Laguna has serious braking at nearly every corner; 125-50 into 2, 85-75 into 3, 115-75 into 5, 95-80 into 6, 100-40 into 8, then 95-40 into 11. All in about a minute and 40 seconds. It's not just severity, it's how damn often you're doing it. It's not the hardest braking track I go to; Calspeed's turn 3 is a 135 to 40 braking zone, but you have a solid 40 seconds before it for the brakes to cool down so it's not considered a track that's hard on brakes.
|
Yeah agreed. For example, I think MSR, especially for the 3.1 course, would be much harder on brakes than TWS. Like I said, brake fade is usually not a big deal for bikes so it is hard to say empirically (for sure) which is worse based on my experience; I have LOTS of laps on both in a bike (I'll be racing at TWS this weekend in fact) but essentially none in a car.
The Hill Country route I was taking when I overheated the brakes had a lot of frequent braking, including downhill, with hardly any long straights to cool the brakes back down again. More like doing continuous laps on an Auto-X course than on a track. |
Actually, Hallett is the hardest local circuit on brakes. I could get my stock 1.6 brakes to fade on hp+ in 2 places there, but never at MSR on either track.
I've overheated brakes on twisty roads in Austin due to (buckle up for the logic) less-intense braking. People who pussy-foot around the track and brake to softly heat up brakes more than someone who's going faster and braking properly. There have been instances where I've had to brake after turn-1 at hallett, then had massive fade in turn 2 at low speed because I put too much heat in on the straight-away. To make the long story short...I'll need the heat management on the first session. |

so yesterday I spoke with ISC racing and they're making a set of dust shield for me. :)

Cspence-your setup is doing next to nohting as is.
Get a shield with proper mounting for the duct and it will then be efficient. Right now you are blowing air on a hot rotor, hardly cooling it if at all. |
