Less economy, less performance and far more expense. If you want a nice noise nail a VR6 in there.
Not here for an arguement but.....
I dont quite see the increase in expense here unless you are considering their use over a significant time frame. Face it, as nasty as carbs are when compared to a throttle body and stand alone ECU package thats set up properly, they are a very cheap option if all you want is some bragging rights, a bit of noise and a wee bit of extra oomph out of the engine (when set up properly, something I fail to see Bogg brothers doing just by banging in a set of rough guess jets btw). Its definately not what I would do and I do see some of your point (certainly regarding fuel economy and engine output/drivability potential) but a full on throttle body setup can be VERY expensive if you are not in a position to do the vast majority of the work yourself. Even using megasquirt and bike bodies your looking at a significant investment which a lot of people just are not capable of justifying or even implementing.
Lets do a quick tot up of some figures plucked out of the air shall we? £200-400 for a megasquirt ECU depending on who builds it or if its on ebay built, £50-200 for ignition parts and new leads depending on what route you take with the ignition (stock is useless and defeating the object), £50-150 for the TB's, £100-200 for the new loom including connectors and add in a fair bit more for crimping tools, vastly more if someone else does it, £50 for the inlet assuming you do it yourself, £200-350 for the inlet if bought out, several hundred for mapping if you want it bang on and your talking serious money to most people with what is a budget setup that would be roughly acheivable by most mechanically minded people. Compare that to £350 for a bought inlet and maybe upto £100 for the carbs and theres not only a big difference in cost but also in time and skills required. BTW, Im aware you can do these things a lot cheaper than the rough prices I have popped in here but not everyone is capable of doing this sort of thing, let alone have the confidence to start such a project with their road cars.
Perhaps its worth you remembering this as it seems at odds with your constant banging on about using OEM brake setups to keep costs down (again, something I see your point with but is sometimes delivered in such a way as to make people ignore your vision on the basis you come across as a prick).......
Did you really suggest someone should put a VR engine in a car and not put a single snide comment in there
