insulating intake for h.p., anyone experimant with this Options

[orange914]

watching a speed report on h.p. gains. gail banks claims 1% h.p. gain for every 10 degrees cooler. i'd have to guess with a cold air intake to outside air and insulating the intake runners so they dont heat sink you could see relitively good gain. just wondering...

On the race car, I used to wrap the exhaust headers and intake manifolds. Also ran a cold air intake. Only problem was with the headers ....over time, the heat would crystallize the metal (can you say cracks?)

Then there's the story of the "Ice Man". He used dry ice to cool his intake air ... finally figured out that it wasn't a great idea when his car wouldn't start on the pre-grid due to the Carbon Dioxide being sucked in .... (IMG:style_emoticons/default/av-943.gif)

Funny story about dry ice and autocrossing...

A friend of mine who was a very good driver in a very well prepared car had an idea. He knew that if he cooled his intake charge, either fuel or air or both that it would be more densely packed molecules and therefore more molecules. He bought a display battery from Sears. These are just the plastic box without the lead cells. But he discovered that the posts were the same as a normal battery. So, he located a motorcycle battery in the interior behind his passenger seat and ran cables to his fake battery. Then he ran cables from the fake battery to ground and the starter. Inside his fake battery, he installed an old device I haven't seen in years called a Cool Can or Kool Kan, i do not recall the brand spelling. he plumbed his fuel in and out through the bottom of the battery. Then he would just pack the can with dry ice before an event. Dry ice evaporates so as long as you keep it sealed it stays frozen and does the deed you ask of it.
I suppose he got a HP or two that he didn't need as he was quite fast in anything he drove.
One event he let his mechanic drive. The guy was kind of a "good old boy" type who was in to Nascar. In the morning we had rain and in the afternoon the sun came out and dried the track. The event was on an oval track that ran the usual mini stock and demo derby crap on the weekend nights... Well our mechanic lost control on the sandy surface left when the rain dried up. He kept his foot into it because that is what the Nascar boys did according to him. He went pretty much full force into the wall making fiberglass feathers out of a nicely restored TVR 2500M front end. As the guys gathered around the wreck and determined that the mechanic / driver was OK. someone noticed a smoke like haze coming from the battery. They started calling for the fire extinguisher. My friend made quick arrangements for a trailer to haul the car out of there before someone could find his illegal modification and attribute all of his winning to it.

My guess? One and a half maybe two HP. More trouble than it is worth...
