Dual Carb Manifold

Firstly, G'day to all, I've just found this site and registered (couldn't help myself).

Got a P6 LTD 351C with the infamous Carter Thermoquad stock setup. I've also got one sitting in the shed as a spare and was thinking of a dual carb setup. Is this feasible, if so where are the manifolds easily available.

Any info would be more than appreciated.

Cheers.

Dmax

Re: Dual Carb Manifold

Only people that use dual carbs are full on race set-ups or just for show. There would be no advantage in it for you.

Re: Dual Carb Manifold

Main reason for wanting to use dual carbs is for some gain in power, wanting to build a warm street motor around 400hp, and for something different with looks etc. You are probably right in regards to practicality, but I get an idea stuck in my head and it's there til a better one comes along.

Re: Dual Carb Manifold

A better idea would be, a bigger cam, weiand accelerator, electronic ignition, 750dp, extractors and an electric fuel pump just for a start.

Re: Dual Carb Manifold

so you want to run 2 carter carbs on a street engine, hmmm crazyness especially when you consider that the thermoquad is rated at like 650 or 700cfm you would be better off running a larger single carb and manifold, if you want the looks go for a funnelweb manifold, i know of a car that runs a tunnel ram manifold with 2 465 holleys and its fairly streetable, but its only in a 1000kg car

Creativity and individulaity are one thing, but some things work and some things don't when it comes to cars.

There's some great tech tips on this site on clevo combo's that work, suggest you have a good read and take the common denominators.

Re: Dual Carb Manifold

It all sounds so nice. I'll tell the missus that the kids aren't going to school next year so I can get the Limo bombed, lol. Speaking to a mechanic, he was telling me that the thermoquads can be set up to the equivalent of a 980 Holley. Comments?

Your right, I might have to belt myself with a reality stick and think of something else for the creativity factor

He could be right, I'm sure out of the box they are 870cfm approx.

Re: Dual Carb Manifold

Hello DMax.
The original Thermoquads were put on big block Chrysler motors i.e. 440's in the early 1970's. They had a flow rate of 800-900 cfm if I remember correctly. You could seek out some contacts in the US who sell kits to rejet and calibrate these carbies. There are some enthusiasts who may be able to help you find the parts you need. Try a google search.
Cheers
Craig
