Re: Edelbrock EFI
The “tuned port” version is a bit more cash, I think. Is it better? My guess without data to back me up is that Edelbrock recognizes the tuning effect of longer runners. To that end I would think they either modified single plane manifold to have equal flowing runners or made an entirely new manifold for the single plane system incorporating equal length runners. It also needed to fit under the hood of most cars with their throttle body. Cost and simplicity also entered into it I’m sure.
The “ tuned port” version removes some compromises and could provide low end torque improvement. How beneficial,is this going to be? Most of us use some kind of higher stall converters so tromping on the gas almost immediately puts the motor close to 3000 rpm so it’s already in almost peak torque so will probably not gain much more in the next couple seconds. Maybe not using a lot of throttle it would produce more torque per degree of throttle opening. IE make a more efficient motor at lower speeds, say pulling a trailer or big heavy car.
I may be way off base here but when someone says “more......something”. I’m interested in how much is more. In this case pulling numbers what if the gain is 10 lbs. ft. Pretty small if you have 300 available with the single plane. Now if it came out 50 lbs. ft. It would be significant.
So again just my thoughts.
As far as power adders, nitrous I know 0. About it. Supercharging, roots blower probably doesn’t apply, centrifugal and turbo is probably possible but not in the market price range.
So that leaves us with a real street system getting close to the late model jelly bean cars at an affordable price.
With this I’ll get off the soap box and pick up my sword and shield and be “en guarde”.
