How many sets of pads in 36 hours?

Chumpcar. Spokane. July. 36 hour enduro.

Actually sounds interesting, but thats gotta be a costly weekend, I think. Gas, tires, pads and rotors...

I wonder what kinda rev limit chip a guy would want to use to get a Neon to last 36 hours?

Idle. Although a crappy rering, water pump, and timing belt sounds like some must do's beforehand....

Pads... Depends on what pads you started with...

The NX2000 my friends run used two sets of front pads on their car during a 24-hour event. They use Hawk HPS pads.

For the 36-hour event, I'd add two more sets of pads and two sets of rotors just to be safe. ChumpCar will likely have a safety break at some point during the event.

I'm not sure what compound it is but I've been hearing some great things about Performance Friction.

Spokane is a pretty fast course and July in Spokane is usually HOT, so brake wear is probably higher than most Chumptracks. However, with the proper high temp/endurance type pads, brake air ducts, and driver instruction, you should be able to go a whole race no problem. Most of the lighter cars (like a Neon) have brakes last many races before replacement. None of my cars ever went through even half of the brake linings in a 24 hour race. If it were me, I'd have some EBC or similar endurance pads and a set of spares just in case.

Whatever you do, get some quality pads from EBC, Hawk or another supplier. In the first LeMons 24 hour race I entered, we went through ELEVEN brake pad changes in 24 hours!

We were running a 1st Gen RX-7 with a Ford V8. Using Autozone, or other crappy pads will cost more in the long run, and make the day a lot more frustrating!

Especially given the room the rules allow you for brake upgrades, don't leave that on the table.

For a Neon, I would baffle the oil pan, add a crank scraper and a huge oil cooler along with a HD radiator of some sort. My older brother lunched his motor just autocrossing it due to oil slosh. He put a Moroso pan on it and it made a huge difference (but that won't fit in budget of course) A new timing belt and MLS head gasket is very important before a hot race like that along with a spare head and gasket set JIC.

On our ChumpCSX we ran into issues with the drivelines (one knuckle came loose from the strut and destroyed the passenger axle) and we lost 3rd gear (common problem with the 555 case) then we lost the clutch disc (split in half) Since the Neon is based loosely on the K-cars, be aware of the potential pit falls and work around them. In our case, the culprit was a rally-racer that over-drove the car and damaged the gear box (after spitting two rocker arms off due to over-revving downshifts)

Also, having good drivers (drivers that will listen) that will slow the car down to save it for the entire race helps. Its fun to go balls-out all the time, until the car breaks, then the suck begins. Set a pace and have them work on matching that pace. If the car holds together for the entire race, let the dogs of war loose for the last 20 or 30 minutes.

If you have the right pads, they should last the whole race. Our lemons cars can go for 4 races on a set of pads. We have used carbotech xp8 and a compound I can't remember from cobalt friction, both with good results. Call Mike Jr at Carbotech and have him recommend a compound for you.

Boy, you guys sure are easy on brakes. My IT Neon needs pads (Hawk Blues) and rotors every 6 hours. Of course, thats running sprint races, not enduro, but still...

My personal Chump experience was a 14 hour at Calgary in a 91 Integra. Repco (excuse me, showing my age here- PBR) Metalmaster pads lasted about 13 hours 45 minutes.

It also depends quite a bit on the car. Our turbo zetec '86 Escort runs Porterfields and can run the entire 24 on a set of road race pads and still have meat to spare. It's a pretty light car though, so I imagine it's easier on pads than most.

That's nearly a grand in fuel based on a 7gal/hr burn rate we experience with our Civic. Holy crap...that's torturous.

IT allows better tires, which adds load to the braking system, coupled with the better suspension allowed and the cars are faster and maintain higher average speeds.

We've been really happy with the Porterfield RR compound. They are not cheap, but they do last a full 24 hour race with some meat left. And no, we're not easy on the brakes

I'd take a look at the Porterfield R4-E (E=enduro) pads http://porterfield-brakes.com/images/portrace2008_11_06_02_41_04.pdf

Also try and do some ducting to keep temps under control.

Pagid I think has some good, long lasting pads. Don't remember the compound though.
