Need Advise - Boiling Brake / Clutch Fluid in Daytona

[Daytona Enthusiast]

My Dad drove his Daytona daily from 1976 to 1990 and never had a problem, but that's with the stock exhaust
manifolds and no AC condenser to contend with.

Did you check the temps of the master cylinders?
I think the problem is infrared energy from the engine is heating the m/c, not convection energy.  My next move would be to fabricate a heat shield and see what happens as this is simple and cost effective.  There was a m/c heat shield used on trucks at some point in the 90's.  I have a nos one somewhere but I can't seem to locate it at the moment.

BTW I love your cars and what you do with them, maybe someday you will come play at Watkins Glen with me.

Hey Tom -

Actually working on a heat shield right now. As for the Glen... I will be down there Oct. 2nd -4th with NASA - we should DEFINITELY meet up.

Mike -

How about something like this ? Allow air to be pulled out of the engine bay by the air passing over the fender top scoops ?

steel mesh to cover the opening ?


The inspection plates in front of the inner fenders could be opened up...    attach a duct and aim the air at the front brakes ? 

Random ideas - not sure how well they would work in the real world

[pettybird]

how about header wrap?  you guys are reinventing the wheel trying to extract heat--just keep it out in the first place!

I know ceramic coated headers are pretty and all but you can grab ahold of one that's wrapped up.

I don't like the wrapped headers, they rot out too quick.

i wouldn't bet against you on that but i wouldn't try it either unless i was REALLY drunk

Well, here in Arkansas, it's been proven that the number one sentence uttered right before death is "here, hold my beer and watch this".

i'm not suggesting you'd want to whistle Dixie while doing it, but it's a hell of a lot safer than grabbing an unwrapped one.  I would say it takes about 2-3 seconds before you have to let go.  the stuff does work.  you can even change plugs on a warm car--it's not fun but you won't end up with blisters. 

as far as the headers rotting out, does it still happen when they're coated first?  most people who wrap do it to $89 headers. 

[NYCMille]

Rolling_Thunder - hmm... interesting, and honestly, it's totally plausible
pettybird - Yep... we are definitely wrapping them.

Hopefully we'll have figured by Friday, i will keep everyone posted.

For what it's worth, I've also seen people using this:

No idea if it works, but.....?  You could just line your engine bay with gold like a Mclaren F1.

   So your hdr temp is at 500 but your brake fluid is boiling over 600? I am no expert but I would go and install some temporary temp gauges strategically around the engine compartment just to ensure that underhood temp is the culprit. Are you sure the problem is not closer to the calipers? Maybe the difference in front end (from your previous car) is not allowing as much air to cool the calipers? (I am assuming the tire/wheel combo is similar to the charger you ran)
