JAnderson,
Sorry, I misunderstood. We used a full sequential system, that the Electro-motive TecIIIr system allows as an option. By doing that, each cylinder gets to use the whole port, and doesn't neccessitate splitting the port. It works great. On the old twin turbo street car, Frank used the older Tech II design and on that one, he had to put a splitter vane on the manifold that went in and was profiled to seperate the port into two halves. That meant that each cyl. saw only a little tiny 1/2 size port. Worked, but not very efficient. That system was very cumbersome and is over 10 years old now. I'm afraid you could try porting to regain some area, but you'd probably strike water. You are right, boost does offer an advantage. Doug
