Fabspeed Motorsports now offers a carbon fiber RS heater duct bypass for all 964 vehicles 1989-1994. This is a replica of the Porsche Germany RS lightweight factory heater duct bypass which was used on all 3.6L RS cars.
-Saves 8lbs/3.6kg from the rear of the vehicle and enables work in the engine compartment much easier with less interference.
-Replaces blower motor assembly and ductwork but still allows plenty of heat just like the factory RS part.
-This carbon fiber bypass enhances the aesthetic value of the engine compartment whereas the stock RS bypass is made from roto-formed plastic.
-Simple do it yourself 20 minute installation.
We have these in stock and ready to ship. Retail price is $325.

Awesome, I will buy this after christmas (unless its gifted to me) Replaces the entire contraption over there? blower assembly and everthing just gone?

 

Yes this carbon fiber bypass removes the complete blower assembly and allows the distributor air hose to reconnect.

 

This piece looks nice compared to some of the CF junk I've seen purchased from ebay.

 

I have a question about this bypass, versus a plate that covers the hole at the top of the fan housing. What is the benefit to this pipe?

 

If you have a 964 or 993, you will need to put a resistor in place of the original heater blower,
as detailed on this site http://www.porsche964.co.uk/technical/noheater.htm

found it here: http://rennlight.com/rstube/

 

Is it possible that you buy the black box?? i'm not so good with wires! And thats not an understatement.

 

Unfortunately you loose heat on the early 964's. The resistor modification does not work for 89 and at least 90 model years. I wish someone could figure out how to get it to work. I keep looking for a second hand climate control from a later model to trade out to do this. Unfortunately the cost is way too much for the benefit.

 

Very nice... hummmmmm

 

Are these applicable to NAs only? I am still trying to figure out if/how to remove heat from my turbo.

The carbon fiber bypass pipe still allows heat to enter the cabin versus the block off plate which completely eliminates heat.

 

But that is only if you have heat exchangers, right?

 

Correct. As those are the ones that are connected on the other end to the pipes that take the heat to the cabin... well, to the blower up front. I recently spent an afternoon replacing the hose that connects the heat exchanger to it, when I had to take one of the heat exchangers to get to an oil line.

 

That's what I thought. Thanks for the replies!

For my application, I only need a plate, since I don't have heat exchangers and the heater bypass that came with the supercharger is a little dinky. Anyone know where I can get a plate?

Thanks!

 

We have the fan block off plate available for $75.
