Yes, it does sound crazy, but hear me out.......
The oil in the valve covers is perhaps the hottest oil in the motor due to the heat of the heads and the valve train. The current steel covers have plenty of surface area, but no real air flow and besides steel sucks for heat dissapation....the aftermarket aluminum valve covers benifit from having fins (still not much air to go over them) and from the better heat dis. properties of alum. Now my thinking is that by adding water channels to an aluminum valve cover, you could help control the heat much better, one could even go a little further with this idea and attach w/screws alum or copper "junction" pieces from the cover to head to transfer heat from the head to the cooler cover..... A very small radiator could be used and I'm guessing less than a gallon of water would be needed.... |

I thought about this the other day looking at the small radiators that cool OC'd PCs I was thinking something like wasserboxer heads... electric water pumped maybe to not rob hp,

Mueller - I'll just sit back a wait for Jake's reply (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
I am pretty sure he won't be on the fence on this idea and MIGHT even have a comment or two on it (IMG:http://www.914world.com/bbs2/html/emoticons/av-943.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/popcorn[1].gif) ** pist - between you and me - I think you are on to something ** |

Nah, too much work. Cast some jazzy valve covers with big MF fins on them, make outrageous claims of 'reducing valve train temps by 30 degrees' and sell them on eBay for $150 per set. Should cost you about $8 to make (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

nah, that would be the "smart" thing to do and I didn't get where I'm at today using my brain (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) |

There is a web site of a company that makes aircooled planes...
great plains or something like that..google airplane and vw.... They casted a watercooled head...no one fron a bus, but a new casting....looked interesting. They also have twin plug heads on all the planes... Rich |

mike, i got the new performance products catalog yest. stumbled across the finned aluminum valve covers and the pricing. can i buy them back? jk. i need to do an internet search for some "smart pills".

This is the way I see the usefulness of added cooling:
If the net goal is to pull down head temp via additional "localized" cooling, you could set up some oil jets and drains in the valve cover and put it all through a bigger central cooler, or an auxiliary one. While oil may not convect the heat as quickly as an equivalent water flow, you have your choice as far as how fast you want to pump it and how well it gets cooled. If a valve cover could be made to be a "cold plate", I.E. water cooled, the most important cooling path I can think of would be the contact surface between the head an cover. In this case, it would need to be a precise fit since it can't allow leaks, but any gasketing to seal in oil would defeat the condutive path. Mike, I'm thinking plan "A" we discussed some time ago is still the best idea. How's the aluminum flowing? |

How hot do the valve covers actually get? Particularly, what is their temperature rise over ambient?

You guys are missing the point. Who cares? Just make money. Believe me, you make'em, list'em, and the suckers will buy. Look at all those 'miracle' products. Don't give me engineering data. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif)

On thing Mike left out - a water jacket would really quiet the valvetrain noise.

for the propane torch, I need a POL to OPD adapter or find the correct OPD to npt fitting and build the torch.... |

How about using a bunch of heatpipes in parallel that lead from the valve covers down to a nice big aluminum heat sink that sits in the flow of air under the car? Sure it will be a pain to design and will probably leak, but at least it would still be air cooled!!!!! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
How about a scoop that picks up air from below the engine and shoots it up and around the stock oil 'pan' and diverts some up to the valve covers. You could even make it out of carbon fiber. (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif) -Tony |

Or better yet, run a series of peltier pads along with some heatsinks on top. 2-3 300w peltier pads on each side might even make it difficult for the motor to get to temp (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

I like the peltier idea.
Porsche actually water cooled the heads on turbos back in the mid-70s but just for a while. They found out better ways to deal with the heat and dropped that project. But do some research on that. You could make a whole sleeve kit for the fours to convert over. |
