It's the MAF that meters petrol - does not require re-tuning if (cold) air filter arrangement is altered to breathe better. It is my understanding that if breathability is altered radically (cam for instance) then larger injectors may be required.

I don't mean to be rude but it is clear you have limited knowledge of how a efi engine works and would recommend maybe doing a little reading to give yourself a better understanding of EFI.

Op there is plenty of upgrade kits that have matched chips maybe you could look into. Any computer modification should ideally be placed last on the list. So It can be tuned to match mods. However some chips will still offer advantages over standard fuel maps but will more than likely use more fuel and increase emmisions.

its as basic as this The ECU takes information from various sensors. In the form of a voltage, A basic setup would utilise a Crank angle sensor, A camshaft position sensor, a air intake temp sensor, Mass airflow, and or Map coolant tempreture sensor knock sensor,throttle position sensor or accelerator position sensor., vehicle speed sensor, 02 sensor. With the info fromthese inputs the computer has a predetermined map to which it is set this map will control the duty cycle and timing. The "MAF" is jsut one part of a big equation A+B+C+D+E+G+H=X,Y,Z. N.B. This is a basic example many modern vehicles will be utilising info from hundreds of sensors and adjust hundreds of things that run the engine. Think of the map a a cross over chart or graph

I think you need two lysholm twin screw superchargers mated to a twr crate engine, twincharged with custom made turbos, a wet feed nitrous system, 8 speed triple clutch semi automatic gear box, the composite brakes from a gt90.
All of this advice might be useful if there was a budget specified. Otherwise its all just speculation.

If you already have 220kw driving 2 wheels only, then surely any extra hp will largely end up as burnt rubber on the road!
Suspension / tyre package instead if you want speed! (as opposed to noise)

Have to jump in here bellky.
bigfatmat1 definitely knows what he is talking about with vehicle EFI and vehicle electronics.He definitely isn't guessing with his info.

Modifying the air intake and full exhaust will make the 5.0 breathe better. The MAF sensor will measure the increased air and adjust fuel delivery accordingly. No need for any (re)tuning or chipping. The engine will not run lean. Unlike the TPS sensor fuel delivery types that require fuel delivery to be increased (re-mapped) at various butterfly angles due to increased air speed/volume.

yes this is correct but all efi cars have a TPS or APP sensor. The computer is tuned to emissions and fuel economy soa remap will make a difference

Ya ECU says if you're getting in X air, send Y fuel (at any given throttle, temp, load etc), and fire at G degrees BTDC.
SO if you send it X+1 air, yes it will correct it to send Y+1 fuel and fire at H degrees.
That's all cool.
BFM's point is that perhaps you don't want Y+1 fuel, perhaps you want Z, because when the manufacturer decided on Y it was with economy in mind, not power.
So by all means make it breathe better. You'll get power gains. But you'll get MORE gain getting into it's brain.

smac has described it exactly right.All EFI computer mapping for standard passenger vehicles is intended as a compromise between power and economy.By increasing one aspect of the formula (ie: air flow)the ECU can only make adjustments as far as the preset parameters allow.Any system adjustments outside these preset limits can only be achieved through resetting the EFI "brain".

Yep I see what you mean^. I like the idea of improving performance without compromising fuel efficiency; modifying intake and exhaust and leaving computer untouched should improve both performance and fuel efficiency.
I guess it depends on how much power you want, and what you can afford in modification costs and running costs. For ultimate performance I guess you'd go for a Powerdyne or Vortech Centrifugal Supercharger kit complete with cam, injectors, ignition, tune, and whatever else is needed. But you're talking big dollars there.

Also OP the 220kw 302w in the AU3 are the most powerful iteration of that engine built by Ford/Tickford afaik. Those engines are the leftovers from the T2 TS50 range and have all the goodies like GT40 alloy heads etc.

That's good to know, cheers for the info. Thanks again to all posters. I've learned heaps.

Just be careful I'm sorry to say though, because the alloy heads have different heat expansion rates than the iron block and head bolts etc. you can run into troubles. My brother's TS50 (very low kms) has had the head gaskets done - luckily he buys mechanical insurance as a rule to combat his maniacal driving style.
Also the company called Herrod is alright with these cars (afaik) - you can most likely buy something off the shelf from them (cold air box and exhaust) and have it shipped and fitted where you are by local mechanic/exhaust shop. Just an idea.
