My primary is producing 10psi but when the secondary comes online it only produces 5-6psi. Any one have have any suggestions?

Does any know where to get a set of good vaccuum lines?
Thanks

 

I got my lines from www.hightempsilicone.com. I got the viton, but they also have top notch silicone lines. I think Baker Precision is another popular supplier, and you can find Hose Techniques products with many RX-7 dealers. The quantity supplied in the Hose Techniques kit I found was almost double what I really needed if I was careful installing it.

5-6 psi on the secondary, assuming this is exactly what happens from 4500rpm on up, could be several things. First, perform the KOKO test and see if both the Charge Control and Turbo Control valves are working properly. http://www.fd3s.net/boost_test.html

LOL i never heard it called the KOKO test, but it does say that at the bottom. HA
