I know its been a while but I am curious.
Have you installed this in your bus yet? Did the tail pipe clear the rear apron and bumper? |

That oval tip is sweet.
I'd love to hear a sound clip of that once it's running |

Thanks, but that is the OUTSIDE of the exhaust pipe. Even so it looks like same cheap exterior finning.

Has anyone opened up one of these aftermarket heater boxes lately to see if the heat exchangers have gotten improved? |
One needs to only look up the rear of the exhaust tube with a flashlight in a dark room. Peering past that first small curve will show the inside fining. |

You can tell a lot by the weight.

Also by having the heater box inner pipes cooling properly in hot weather the exhaust gets cooled/shrunk so as to not have it back pressure against the cylinders and heads. Thusly everything runs cooler. Also why with the heater boxes shut off to the interior of the VW the stock air valve in the front of each box switches to venting to the outside of the heater box. Go thru the link in that post for more heater box info and study up.

Here's the deal:
If you have heater boxes then connect the fresh air hoses, even if the heater boxes no connected to the body.
If you have J-tubes, then you need Industrial Tins (Type 126) to close off the gap between the sleds and heads to keep the exhaust heat out.
That's how the factory designed the systems to work.

If you’re not worried about a bit of power loss you could go with a larger pulley or higher flow fan. But don’t over rev the fan or it can blow apart.

From what I understand is that if you have heater boxes you absolutely need the airflow from the fan shroud to get rid of the heat exchanger heat. If not the heat just radiates up and cooks the oil in the pushrod tubes and the piston and cylinders. What you’re doing is actually making it worse.
The fan shroud blows air across the fins inside and removes the heat and blows it out the exit duct and safely away from the engine effectively cooling the engine. You mess with any of that IE larger heat exchanger fins or not allowing cooling air to flow through will cause higher temps. |
Perfect, that was the explanation I was looking for.
Thank you! |

Understood, but you will have a hotter running engine during the hot weather, that is not good for engine longevity.
On the other hand it does get cold the farther out east you go, and not that much distance.
Talked to Steve of Wolfgang Int. years ago and he had big cooling problems with the early fresh air heater boxes with big engines. Only fixed by going to the later 1500/1600 fresh air heater boxes. |
Can you explain the science behind the lack of heat conductivity of these boxes and it's relation to the engine running hot?
Would J tubes then cause an engine to run hot?
I didn't think (or assume) the heater boxes are aiding in dissipating heat from the engine under normal circumstances.
I'm not disputing what you have said and I appreciate the input but I am just curious to hear more info.
Or maybe I just totally misunderstood.
In the summer I use those caps to block off the heat ducts on the fan shroud to not even blow air on the boxes. |
