I'm looking to install some brake ducting on my 01 Prelude which serves as primarily an HPDE car. What I'm weighing here are the benefits of various ducting materials that are available.

I am currently looking at 3 types of ducting, all in 2.5" diameter:

1) 600 Deg F. Aircraft Silicone from Racerpartswholesale $60 for 11ft

2) 350 deg. F Aircraft Neoprene from Racerpartswholesale $43 for 11ft

3) Pool/spa tubing from lowes as used by 57STS in this thread

- about $5/ft

For the purposed that this vehicle is intended for, would it serve me any advantage to get high temperature resistant tubing for RPW or would the Lowes stuff work fine?

 

We run a 3" dia. (guess its silicone??) hose - typically something like 60 bucks a 12' section from BSR Products or the like. I would not suggest running dryer ducting (the thin stuff) nor would I run the 2.5" if given the option (especially on a car that size - we're running a 3" duct on a 2150lbs. CRX).

 

Adam is right, anything less than 3" is considered to be a waste of time. I used the dryer duct tubing with good results, but I replaced it after almost every race.

Wow! I had no idea that it would be THAT bad. I guess I'll look more seriously into the silicone ducting then. Thanks.

 

I use the orange high-temp silicon stuff. Much more robust.

I have also used the 350deg stuff, and I've used pool ducting. The 350 stuff was fragile and easy to damage. The pool ducting I simply melted. So, this is one case, IMO, where spending the extra 15 bucks or so is well worth it.
