very interesting Rex and I guess in the application we're using it that the excess wear that slides suffer ( in comparison to 'flies)isn't really too much of a concern,....right now I'm side stepping the "stack" idea and am concentrating on a twin throttle body manifold . I just sawed the top off the stock manifold and put a kind of pent-roof top on it to add a bit of plenum volume and top it off with two of the standard TB's chimney style on top .We had a single unit on the motor in a similar config' and purely on the reasoning that there was room for two I'm doing it .
Now , another question for the gallery. This motor is a 3.8litre and the stock throttle body is 60mm, I'm thinking I'll set the throttles up so that the second one goes from 0-100% after the first one reaches about 40% , too early ?, too late ?....... any comments
In another realm , my road car is making a fool of me ........the old straight six got a set of lifters and a head the other day , now it won't even start , it'll backfire occasionally and the local dogs are hoarse from barking ,but run ? not on your Nellie!............Sick of staring at it , and having nearly scratched my scalp off it's all coming apart again , I know it'll be something silly , really silly and you know what?.....you're not gonna hear about it!!!!
