I don’t know if using the stock LSA fuel rails with the new lid is possible. I wish some one could confirm this.I like that the stock fuel rails can still be used with the new lid? do you have any pics of the lid installed?
That's what I am hoping for. With the huge surface area of the core in these lids, I wonder if there is room to run a decent lid spacer to give air exiting the rotors more space to spread out before entering the fins.Kong said on FB that it was compatible with stock LSA without machining.
I think Kong designed it to be a dual pass. The air gets pushed up through the brick and pressurizes the small space above it (1st pass), then the engine inhales the pressurized air from that small space which forces the air to pass back through the brick and into the engine (2nd pass). I think putting a spacer might disrupt that process and force air into the engine before it has a chance to pass through the brick. Of course I'm no engineer so I am only assuming. Maybe Kong kept the space above the brick relatively small to avoid starving the rear cylinders, but more than likely its just because thats all the room they have to work with.That's what I am hoping for. With the huge surface area of the core in these lids, I wonder if there is room to run a decent lid spacer to give air exiting the rotors more space to spread out before entering the fins.
Also, looking at the underside of the lid more, I wonder how much air makes it to the back two cylinders. I would think they would receive less than the rest and may end up running a little richer. That's just my thought as a person not trained in fluid dynamics though.
Agree about the rear cylinders but not sure if the brick could easily be designed to accommodate and then the lid would be larger and would interfere with the cowl on the Vet.Its clearly a function of sealing out the lid to create the true dual pass...aerodynamically it is not all that appealing as mentioned...flow is going to become more turbulent making the sharp transitions to reach the rear cylinders...IMHO the intercooler brick should be made to have 'ears' that cover those small areas with core...not a lot of rev work to do that beyond the custom core with front coolant ports.
Any spacer would have to now include straight runs to mimic the 'new' gasket area required. I have one and it is just the perimeter and an extension for the square brick.
I think Edelbrock is making the production lids so it isn’t quite as easy to make changesGiven that Kong already has the CNC program for this lid, adding additional headroom between the top of the lid and top of the brick should be a fairly easy edit for the CTSV/ZL1. Just depends on demand and Kong's appetite to add a second SKU.
Easily, nope... So you get an off the shelf core thats used in other applications (major assumption on my part, but why else would you totally close out the rear to cylinder's straight path of air?) This is much different geometry than on a single pass, so I get that its new, just assessing is all.Agree about the rear cylinders but not sure if the brick could easily be designed to accommodate and then the lid would be larger and would interfere with the cowl on the Vet.
