Crazy idea

[JNadal]

instead of running the air to the heater boxes or blocking it off completely, why not direct the air to the airbox or carbs?

[dickster]

because its hot?

[JNadal]

but it can be intercooled! btw Im not crazy - its 2 in the morning

[JNadal]

oh, and if the air was really hot then there would be no need for the heat exchangers would there?

[aigel]

Why? The air isn't any fresher than the stuff coming in directly through the grille.

the point is not for fresher air, but to put more air into the motor and possibly emulate a tiny turbo setup with a couple psi of boost

You can't make any significant pressure with a fan. Not even enough for the heater, so Porsche had to add another, electric fan!

Now go to bed, before you are going to suggest huge air scoops on the roof.

Massive GT1 air scoops yes... its all coming together now

You need some sleep, these are all horrible ideas

No, no, no.

Don't discourage him. Encourage him.

We need people out there to actually do things so my ideas will seem normal by comparison!

Why not plumb through one of those a ice chest coolers then add a shot of Nitrous. That should take care of it!

Only cars equiped with mass air flow devices will benefit from an increase in air flow. So carbs and MFI are out as it will throw the mixture off. It's an interesting idea, and the air is hot only after passing the cyls and out the bottom. To use air dreictly from the HE input side, IOW, redirect the hoses, would make more air available in the air box.


Add in a bigger throttle body to use this available air and some performance gain maybe possible IMO. It will probably be more the TB, but at least it won't starve for air.

Oh, and HE's are used so warm air can be in immediate supply to defrost, etc. Otherwise, air off the clys could be used to warm the cabin. Yes, I thought of fumes. Fumes can come from the head pipes too.

the best part will be when you open the lid. People will say some interesting remarks upon discovering the hoses. I would love to be there when that happens.

Good thoughts, but any increase in performance would be so negligable that it would not be measureable with conventional means IMO.
Prolly less than installing a K&N.

You would be lucky to get pressure equivalent to an inch or two of water, about the same difference as dropping a few hundred feet in elevation. Axial single stage fans like this are designed to move volume, not build pressure.

I would prefer to have that air moving across my cylinders and heads than to have it routed to the intake system.

The above are guesstimations off the top of my head and I didn't use a calcumalator or look anything up, someone out there may be able to use the formulas to be more accurate.

I wish I had god thoughts.

I guess I'm limited by my mortal, lustful urges.

Yeah, it all makes sense. Those German engineers just missed an easy, obvious way to substantially increase horsepower at virtually no cost in dollars or weight. Yeah, that's likely.

Hey man, sometimes that fantasy is the only thing that keeps me ALIVE !!

And if you want to get really crazy (as if you aren't already there), why not replicate all of the sheet metal bits that make up the 911 unibody in aluminum (or carbon fiber !!) and then weld them together to form a super lightweight Porsche chassis?

Come to think of it, wasn't there an article in Excellence recently about someone who did this very thing back in the 80's to a 928 and reduced the weight by fabricating the chassis in aluminum and raced it at Datona?

Otherwise, air off the clys could be used to warm the cabin.

'Nother crazy idea. Why not re-route the oil cooling lines through the front trunk and install a heat exchanger just like water cooled cars? Double benefit of cooler oil and warmer cabin temps.

Man, if my reputation as a mechanic wasn't already less than zero, I'd be tempted to start a whole thread encouraging the Pelicanheads to brainstorm outlandish performance ideas. It could be funnier than the "Admit Your Stupidity" thread !!

[}{arlequin]

it's all fun and games (and ideas) until somebody installs shopping cart casters under the nose of the car....

I already did reroute the heat thru a heat exchanger in the front trunk of my 912. This was back in the 80's. The heater worked great !! The drawback was although the 912 was great in snow it disliked all the salt they put on Binghamton,NY roads.

I had added an external oil cooler in the engine bay of the 912 to help cooling in summer. Than came fall and I got the brite idea to move the whole assembly to the front of the car for winter.

Not knowing if the engine oil pump could handle the extra oil plus the extra distance of travel I wrote Harry Pellow "May he rest in piece !!" via of all things a "Hand written letter" Email was not something I had at the time.

Anyway Harry wrote me back saying it sounded possible and that is when I learned he grew up a few miles from me in Vestal , NY.

So I ran rubber hose from the back of the car to the front via the useless ducted air lines in the rocker panels and than out into the front trunk compartment.

I used a VW Gas heater blower assembly and mounted my external cooler to it.

I even used a T-thermostat and ran copper tubes around the exhaust pipes to scavage more heat for the winter.

I later removed the copper tubes as the sytem produced plenty of heat without them.

Lessons learned:
1. Don't use rubber hoses as they don't like oil.
2. Harry Pellow was a great guy !!!

I think I still have Harry's letter floating around somewhere.

And by the way I saw this heating method available thru JC Whitney "Or is is Worchokosky" a few years back for air cooled beetles.

Heck, anyone can spell stuff the right way, some of us just have more imagination

[svandamme]

got a variation on that idea :

why use air from the back to heat the front

when you got an oil cooler in the front???

haven't figured out the full details yet

but i'm on phase 1 of the setup
out go the HE's, in come the headers
block off plates in place
flapper boxes and hot air tubing , be-gone

phase 2 will be

pulling oil lines through the old warm air pipe

and fix an oil cooler in the front

thinks i still need to figure out :
do i use one oil cooler for everything
or do i use a cooler for cooling , the normal way + a smaller cooler in the smugglers box , that i can turn on/off... and have a little blower to blow air to my cabin...

i might even use the old red lever in between my seats to control the valve for my heater radiator in my smugglers box
