Throttle body modification

Some people in the USA get bigger USA ones for their EFI conversions using the 3.2 manifold on their 930/965's.
I could email and ask them if you would like to know. Maybe you only want to source from the UK.

I have emailed two people in the USA about it.
Both contacted me, if only companies that sell products were that quick...
1... I am using an Accufab aftermarket throttle body. This one fits a Mustang and has an adapter to fit the 3.2L intake. If you want a bigger throttle body, have the original bored out another mm or so rather than buying something like this (75mm) - unless you are building a real monster. This was overkill for mine.
2... Contact Marco at Billet design he can fix you up.
So,

Also I note the first guy had some headers made by Marco.
Marco's work is supposed to be excellent, many people have said so.
How much bhp are you targeting for ?

Before doing this, I would make a serious enquiry as to the torque (not the power) of such a mod. Cylinder filling is a function of airspeed and at low engine speeds, the larger throttle body can perhaps influence this negatively.
Of course when you are at Wide Open Throttle (WOT) then it's different.
I had heard that the limiting factor on the 3.2 was allways going to be issues like head / cams etc not intake breathing (different for the 3.6L 964)
Thoughts ?

You can't put much more aggressive cams in as they don't work with the air flow meter. The list goes on and on.
You can of course supercharge the engine as long as you don't have a 915 transmission but it is expensive.
For bigger power twin turbo is the way to go. A single turbo like the 930 is laggy and if starting from scratch twin turbo is the best.
For about £10K (single turbo) you could do 0-60 in 4.3secs / 360bhp
You can see why I just bought a 930 with a G50 in it as my 3.2 is a early 915 car.
