I was in the market for a new dual carb linkage my weber idf's. I searched around and decided on a bellcrank style linkage. I liked the CSP linkage however I wanted to spend around $100 (the csp is around $150 with shipping). I found one that looked decent on TheSamba.com. http://www.thesamba.com/vw/classifieds/detail.php?id=660468
I decided to purchase one. It cost right around $100 with shipping and paypal fee. It took about 10 days to get from GB to US. I installed it a few days ago. The quality is very good. I have installed it and my first impression is that I should have thrown out my crossbar a long time ago. Much more precise and easy to use than the crossbar type. The problems with this were that I had to rig something up for the bellcrank return spring (very easy- took a couple minutes) and it is necessary to rig up some sort of throttle cable hold. Overall very pleased. |

Yes and no. I did remove the thermostatic flaps. I have read that it is a bad idea but I still was compelled to remove them. I've got an external oil cooler. I don't remember the size of hand. Removing the flaps changes the airflow balance between both sides of the engine as well as the "throw pattern" of the air over the cylinders/heads. I'd keep an eye on your cylinder head temps. Westach makes a nice dual cylinder head temp gauge that fits in a 2-1/16" dia opening. I was under the impression that the flaps would mainly cause an uneven cooling of the engine when the engine is being warmed. From what I understood, I thought the flaps were completely open when the engine is hot. Is this true? The reason that I took them off was that I bent the flaps when I was rebuilding my engine. I took them off to rebend them and I forgot to reinstall them. I noticed once the engine was back in the car. |

I was under the impression that the flaps would mainly cause an uneven cooling of the engine when the engine is being warmed. From what I understood, I thought the flaps were completely open when the engine is hot. Is this true? When warm, the flaps are open as far as they can go and they direct the air. On the oil cooler side, the flap covers the oil cooler when cold and then moves up to allow air through the oil cooler and over the heads and cylinders. Removing the flaps in their entirety does 2 things. It provides an unbalanced airflow (ie. one side gets more airflow than the other because the pressure balance has been changed from how it was designed) and the ability to direct the airflow is lost. |
