Great job!!! I have a question for you guys, I have asked a few different engine builders this question and I have gotten polar opposite answers with confidence that their opinion was right. My question is this, do you lose low end torque with a single plane manifold and multi point injection just like as if you had a single plane and carburetor?
my guys aswer was no. With todays technology---better camshafts, more efficient head design, better exhaust, have changed the way things work as compared to years ago when there was truth about the dual plane statement. Through extensive dyno testing, these guys found that there is better power and torque all the way around with a single plane setup. He said the most common problem with people running a spi is component mismatch, ie, to big a manifold, a lazy camshaft being a very big problem, cylinder heads, exhaust, and so on. Here are some dual plane pros, long runners for a stronger signal, overall design works well with old technology, low profile. And some cons, fuel atomization dimminishs from the runner length, because of design there is always 1 runner on each side that does'nt keep up with the rest, the banks pull only from half of the carburetor. I know I missed some of both but this was a lot of info to remember. Crude Dude, If you would like to talk to him let me know and will set it up. He will blow your mind, and he's cool too!
