Anyone upgraded to larger intake tubes on dual setup of XKR?
So by looking at the intake pipes on the dual setup of the XKR
especially at the squished portion of the pipes, I thought intake would be a little restrictive.
I conducted a test with a vacuum instrument. Plugged it in on drivers side intake tube where the crankcase ventilation is connected. Ran at full throttle and came up with 20 inches of water vacuum at max Wot. Now Im not exactly sure how that translates into entire system vacuum if I actaully make a conection at the throttle body, but either way curretn intake is restrictive and there is definitely room for improvement
Im thinking to at least get the squished portion replaced with a round tube of some sort
Anyone have relevant info as to intake upgrade for this setup?

20 inches on one intake side possibly means up to 40 inches of water total restrictions. 28 inches is 1psi boost, at 40 is 1.5psi boost lost...

That blue car is one of the Apex GT3's... https://www.jaguarforums.com/forum/m...ing-car-95277/
There was another intake design for the GT3 as well...
There was another version of this with the box section made in carbon fibre.
Google images for Jaguar XKR GT3 you might find it.
EDIT ah yeah, it's in the link I posted above LOL
EDIT AGAIN, beaten by jahummer hahaha

This is the one I was thinking of, my bad though as it is only part stainless.

There you go , knock off wheels. Don't necessarily like the design but all the same they are knock off's. I'll have to see if I can track down the mfg.

Did not realize that was what you were after. Yes those would be very nice. I believe there are adapter kits available (for the hubs, not the wheels), certainly would be nice for track days.

Look at all that space to work on the front of the engine! Water pump and thermostat changing would be a piece of cake. Who need a friggen fan anyway?
Getting to the duckbill would still be difficult, but wait! There's probably no air-con in this car anyway, so no issue!
