I guess what you are trying to say is that it flows more than your inlet port so there for there is no restriction.
If so why spend another £2.5k on something different?
You say:
-Re-buildable? So what. Why would you want to get inside your inlet manifold?
-Different diffuser. Why would you need that? You say the Area six one has perfect distribution across all cylinders.
-Bigger runners? Why would you need that if if the Areasix one is ZERO LOSS?
At the end of the day i could fabricate and sell the area six one you have shown for £250 and still make a reasonable profit. To me that says that someone is getting £500 for simply being the middle man.
ok mate what ever you think thats your opinion , zero loss is across all cylinders not the volume it can hold in the plenum (cubic inches ).the jenvey is far bigger in volume (cubic inches) size than ians inlet and we all know that a good inlet flows 1.5/2 times the capacity of the engine.
- rebuildable and easy to change componets of the inlet which drasticaly alter the performance of a turbo charged engine. air horns can add masses of throttle response to the engine so you can choose from many different air horn designs from the jenvey range to fine tweek the engine but of cause you would know this better than me being a mechanic.
-different diffuser purely for my application as iam going 4x4 in a mk6 fiesta so it will allow me to mount the diffuser top or bottom depending on whats going where and how much room ive got (ideal for me) as i dont want to be cutting up a new inlet and having it rewelded.
-bigger runners , ive stepped upto 48mm from 45mm as we have added a extra 2 degree tapper as they have been ported from top to bottom of the inlet runner and the zetec engine flows best at 15 degrees if i remember right and the jenvey plate is 12.5 degrees ,this again will flow more air but it effects velocity .runner lenght and shape (which i can change as well with no welding and austen stated that 12 inch long runners would be best for max torque which i will never fit in) determine velocity and relate to what is called a ramming effect on a engine. air is thought as weighless but its not the case as talking to many cylinder head peeps that the fast momentum will turn into kinetic energy so if the runners are tuned correctly that energy can be used to force air past the inlet valve and raise the volumetric efficency which inturn will raise bhp and torque. longer runners will have an effect at increasing bhp and torque at lower revs while shorter runners will increase bhp and torque at higher revs so you need to find the balance between the two.
- £250
ok mate you might be able to fabricate something like that but as for profit not much i think. first of all you pay for quality and jenvey stuff costs so ian aint ripping anyone off as nobody HAS TO BUY THEM!. the inlet plate is £220 , x4 air horns £100 , machining of the inlet plate for injectors £40 , throttle body plate machining £20 , fuel rail £35 , fuel rail brackets £20 , the alloy plate cut to size (i would say £60) welding (dont know but could find out as jim is welding my car ) vaccum fittings £10 so i know ian doesnt make that much on them so for your slating of him being a middleman is a bit below the belt.
as for the design flaw , you have only got so much room in a mk3 fiesta bay without changing everything so that was my choice but it still made 500+bhp on the dyno so i think most people will be ok.
