3 weeks and counting fellas and the new fire breather will awaken!!!!
I can brag till thye cows come home but at the end of the day the proof is in the pudding. It will atleast run a 14.0 at 100mph.
Comp is being raised to 9.8-1 to burn as much fuel as possible.

Something to remember....whenever you go over 70% load and/or you hit WOT(anything over 3.7v typically) the EEC will go open loop hence, the HEGO's are ignored.
The richness you see is typical factory calibration.
Why so rich? It's a safety measure to protect the engine more than anything.

Dude you've answered a question that I've pondered for a long time but never bothered asking. Thanks!!
So porting your MAF housing to let in some pirate air to clean up those AFR's isn't a bad idea after all??????
On instantaneous wide open throttles I've always believed the ECU went back to its base fuel map, thats how all this porting business came about.
Oxy sensors, MAF, temp sensors I always thought of as secondary adjustments because their goverened by natural forces. Unlike a TPS that uses a direct electrical current and is simplified in its operation (quicker to respong to changes).

Things ar progressing quite well and we will soon know whether I'm all talk LOL :lol: .
I've just picked up a high volume oil pump and HIGH ENERGY sump. Want all the protection I can get, I personaly can't believe these things have a smaller oil capacity then a 4L!!!!!!!!
I get back my balanced bottom end on Friday so more pics then.

Anyone who modifies these things for more squirt and doesn't improve the oiling system is kidding themselves in my mind.

Is this really still the case or have hings changed? There seems to be a huge change in some of the "mechanicals" in this engine.

None the less good luck for your 13 sec pass.

It will be my pleasure to put you to shame XH5LWEPN with my 1,700kg pig.
Everything is pretty much stock so I don't know what your talking about??? Exciting times ahead boys none the less.

Porting your MAF or using an aftermarket MAF designed for bigger injectors without recalibrating the EEC is a common trick. It does however throw out load calculations and therefore detonation can result due to increased spark advance and lean areas of the cal. that may not have been there before.
As for the other sensors...O2 is used in closed loop only. MAF is the single most important sensor as it determines both fuel and load and therefore spark control. Air and coolant temp are also very important to provide offsets to the calibration. TPS is probably the least important as it only indicates demand...ie Idle, part throttle and WOT. As far as fueling goes It does have an important part to play in accelerator pump functions.
I'm not sure I understand the "direct electrical current" part but if you're talking about response time you should know the MAF is actually faster responding than the TPS. It has to be because it needs to measure the Air Mass many times per revolution of the engine.

BTW what's an X307??

Pete.

Sorry mate, didnt think you'd snap and take the bait on that one. Still abit fiesty these days mate?

Let me know when you beat a time of 13.6@104mph, by that time i probly would have too.

Alloy heads, roller rockers, Tickford cam, etc etc don't make it stock anymore :D I doubt you will see 13's with this setup, but good luck.

I'd suggest you also put the HV oil pump back on the shelf and go for a stock volume pump.

Pete - X307 is the p/n for GT40x turbo swirl heads denoting 58cc chambers.

Ahh so it's just the individual part number for the X305....which is a pair of those heads. So why not say that?.....I mean who's going to buy one!

Probably someone who lunches 1 head... and needs a replacement? :)

All the Ford alloy head p/n's are only for one head :shock:

You then order either one or two :D
