Congrats! This seems to be a good project!
My idea is something like this, on the photo below, but with 3 throtlles instead six. You know? 45 degrees from the intake port. With the gravity doing its job!
I don´t think that 3 70 mm throtlles is a lot. First of all burn alcohol, need more air than gasoline. The photo´s engine has 300 bhp and has 6 45 mm throtlles. I think I´m arround 280 bhp.
About the intake, i made a mistake. Sorry. I meant alum foundry, not forged.
The MS units for sell on ebay are so expensive. I´ve been looking for, but an assembled MS is about $250.00. This is a lot of money for me!
Do you buy the MS visor or you will use a computer to set it?
