Alright, this solution came from VHR. Tey are a company that I bought my 9lbs pulley from. They say that you can solve your fuel lean problem with your supercharger by t-ing off from the boost port and running one end to the fuel pressure regulator and the other end to the boost guage. They insist that they have done over 50,000 miles of testing with no negative results on the engine. Now with that said, I did pruchase the pulley, but with brian's(URD) advice I did not install it. I have 3000 miles on my tacoma with the supercharger installed at 100 miles and have never heard any ping or knocking so far. I may not know what to listen for? I also have been getting alot of carbon build-up on my borla stainless exhaust tip, maybe suggesting it is running rich? VHR saya that with this set-up your fuel pressure will boost with your air pressure at a 1 to 1 ratio. Whether this is true I do not know, can anyone advise? I have a picture of the diagram and will try to attach it, but I do not know how right yet. Anyways cap off your port coming out of your air-intake silencer and t off the boost prot to support the fuel pressure reg and the boost guage. good luck and give me any thoughts you might have. Tell me how to insert a pic too.
That is about as old as the hills. It has been the standard SC hookup to the fuel regulator for years now. That alone will not solve the ping issue but it helps some. The stock injectors are too small to fuel the engine under high boost.
