Ran across this interesting XJS engine bay on the JEC site

I've never seen anything like this intake manifold. I'm wondering if anyone can tell me how this thing is throttled?

 

Looks like it has sliding valves rather than butterfly valves...

 

hmmmm... New to me. Thanks, I'll look it up!

 

A far nicer looking job with webers I think at haynes

 

Constant air. Variable injection???


Wild a... guess..

Biased: Odd looking "T' ! Seems well executed though.


My son is revising his "T" version. Very low. No radiator up front. Those housed in and under the "bed" at the rear. E fan and air draft cooled.


Complex front suspension. Partly fabed by cut, weld and grind technique. Partly by milled alloy. Coil overs.


Very much moded Ford 460. Lotssa noise and power and far too fast....

If it was a diesel, that would work. As it is a petrol engine, you'd be very risky doing that... Especially with the valves and valve seats as fitted to the V12 Loads of air and little fuel = very hot temperatures (lean mix) resulting in loads of wear on and damage to the engine...

 

So, apparently sliding throttles are a common thing and I had never even heard of them! I found a lot of interesting engines while looking.

That weber setup looks insane!...ly awesome! Herman Munster would envy this ride. I can imagine that tuning this thing would be a muti-day affair and require learning a second language just to keep up with the required cursing. Beautiful exhaust pipe work!
