Carb relocation - any one ever tried it?
I'm toying with the idea of relocating the carburetor on a car I am building to resolve a hood clearance issue. I realize this idea may be a bit out there, but I have seen it done on draw through turbo applications, and was curious if it's ever bee done on an NA motor. Assuming I built an adaptor with smooth turns and plenty of cross sectional area, could this be done without a negative impact on performance or drivability?
Obvious answers to this are: give in and put a hood scoop on the car, or get a different intake manifold, but I'm really looking for some technical thoughts on the feasibility of the question above.
Input appreciated.
thanks.Zach

My concern would be a possible drop in effective vacuum from the intake. In a draw through application there is another source of force drawing the fuel/air mixture to the intake manifold which is not there on a NA application.

My barely educated guess is that youll lose some throttle response from the added plenum volume.

based on your comment, are you suggesting there may be a potential problem with fuel pooling up at some location?

Yes..remember fuel is heavier than air...the straighter the shot it is for the fuel to make it to the valve the better.. why do you think tunnel rams run so well... because the fuel doesn't have to turn any corners... Originally Posted by Zachalanche

makes sense. sounds like at minimum I may be negating the benefit of having a high rise intake. Originally Posted by ChevelleNV
