Twin throttle manifold, anyone done it?

You see it on lots of Holdens but why not any Fords? Surely a twin throttle manifold would be a good thing on a high powered Windsor. I am guessing it has something to do with the throttle location but I have seen an EL XR6 with a twin throttle setup here in Perth. Any thoughts?

Re: Twin throttle manifold, anyone done it?

My friend/mechanic converted his own EL XR8 to twin throts by blanking of the side where the throttle body normally sits installing 2 on the other side at the elbow. He said it gave a little bit more up top but the biggest difference was it made the car ultra responsive almost snappy to drive.

F series run two 50mm TB's, but each serves 4 pots. Shame the plenum is so big.

Re: Twin throttle manifold, anyone done it?

There use to be manifolds made to allow you to run twin throttle bodies but they didn't really give any more power so they never took off. Much easier to just get a bigger throttle body, the 65mm ones are good for 250+kw and have excellent throttle response while the 70's are good for 350+kw and still give good throttle response

Re: Twin throttle manifold, anyone done it?

Good enough pics mate..If the original was machined off & welded it would look very nice...Was this before or after Pick and Pay ???

Re: Twin throttle manifold, anyone done it?

A company in the states called BXR manifolds, used to make them.

Quote:
BXR "BALANCED X-RAM RUNNER"
Quote:
If there was a gold medal for the wildest looking 5.0L induction system, BXR's Balanced Cross Ram intake manifold would take the prize hands down! It looks more like something off a mid-Sixties Mopar Super Stocker than an EFI manifold for a 5.0L Mustang, but the concept is unique enough to justify a patent (number 5,551,386). The BXR has 18-inch runners for a good compromise between good low and mid-range torque and maximum high end horsepower, and all 8 of 'em are absolutely identical in size and flow.


There is some info around on some of the US forums, but I haven't been able to find their website, so not sure if they are still in business.

Mr Jucy: That's an interesting set-up your friend has, but the old inlet position must cause a lot of air turbulance in the manifold... as ebxr8240 pointed out.. it would look heaps better if cut off and rewelded... but would also help with performance IMHO... I believe this set-up he has also effectivly reduces the runner length so there would be some low end grunt lost...

Re: Twin throttle manifold, anyone done it?

Tickford2001 I think from memory they are 55s

Fuse yeah it would look better if he finished it off neater but it is his own car that he is constantly trying different things on so was to fussed about making it pretty. He has actually changed the inside abit & added to the side the throttle bodies are on to give it a larger plenum (spelling?) which he has feels most manifolds lack he has found this makes it alot more reponsive also this car will soon have forced induction which would suit short runers & will make a plenum volume even more important.
He made another all custom manifold that had cross rams with a plenum on both sides & a throttle body at the front of each but has gone to this just for packaging reasons.
Neither system is perfect they are both more like prototypes but theydo work & give you an idea of whats possible.
