I was looking at some of the specs on the T-series again and noticed that the airbox has an aluminium venturi going into the mass air meter.

Can anyone tell me if this item is on the EL2 XR8s? Also stories on the EL2 XR8 mention the use of a 'cold air box as used on the EL GT. Is this referring to the venturi I just mentioned or some other design change from previous models?

Kon, I haven't seen the T-series but I do have a 98 EL. It has a cold air intake that is entirely made from black plastic. It twists up from the air filter box to an intake scoop that sits on the passenger side of the radiator support. Hope this helps. I'll get some pictures of the XR8 on my web site soon.

Kon,

I'm not sure if this is what you are talking about, but from having a look at Jeffs ELXR8, it appears to have a spun metal belmouth on the exit to the air box.

Yeah, I ended up buying one. I almost choked when I heard the price - $240. I thought this had better be one super duper airbox. Turns out they sell it with the mass air meter attached. Oh well, I can always sell the meter separately.

Anyone looking for a new 70mm mass air meter?

I'm willing to sell the meter alone for $150. Bear in mind though that the EEC5 in pre series 2 EL XR8s is configured for 55mm meters. If you want to run a bigger one you either have to swap the EEC5 with one designed to run the larger meter or reprogram your EEC5 MAF transfer values.

Does that mean that the EEC5 in the EL series 2 XR8 that I have will run the larger mass air meter

Your EEC5 will run properly with whatever meter it was programmed for. If you currently have the smaller meter then no. I was under the impression that the meter size was increased from the EL series 2 but after speaking with someone yesterday I find that may not be the case.

I'm not sure how feasible it would be to swap an AU EEC5 into an EL or EF, particularly if it's an auto. I suggest eeking out expert advice.

So, I'm assuming from the above (and that the 6's use MAP) that the AU 6's don't have this fancy belmouth in the airbox!

Jeff, when you're finished working on the new intake - how would you like to produce a few copies of the belmouth for the airbox?

How about some kind of a tech article at the site on the MAF sizes / EEC compatibility and the T-series intake setup? If no one else wants to write it I will do it, but I would need all the info first. Also, I will check the size of the MAF on my EL, it should be either 55mm or 70mm, right?

That sounds like a good idea - I have done some work on the 6's MAP system, as well as some basic stuff on the computer EEC V only) and accessing the diagnostics that I could add to that.

The venturi alone, should make for a cleaner exit of the air from the air box and entry into the intake plumbing. This should result in more air drawn into the engine resulting in more burnt rubber smells comming from the rear of the car!!

On the 8's if you add the bigger airflow meter as well you will gain additional airflow (with the obvious benefits) as the standard meter is apparently fairly restrictive.

I bought the ventury from Brad Garlic Ford top Ryde for $27.00 Will find out dyno day if makes any difference.
About the bigger maf.Though I have the Cobra computor:The hot wire electronics are interchangable in the maf.So to my small knowledge that part can be changed over to the 70mm maf from the 50mm maf.After all if you buy a C/L 73mm maf from the states you only get the base not the electronics etc.All I had to do is disconnect the battery [earth] for about two hours while changing maf.Need tamper proof keys to swap over hot wire in maf refit in filter/inlet pipe.EASY.Connect battery earth,then ecu programs itself to new maf.It DOES make a difference..Esp with exhaust mods as well!

Paul yes that is what I did too. but Kon is CORRECT... you do need to calabirate the MAF. Or the car has erratic idle and bad fuel economy. How do I know? Not only read it online but I am having this trouble. I think I am going to but a EL-GT ECU. What size MAF is on those Kon, 65mm?

That's right. Either the computer is changed for the new MAF or the MAF is tweaked to fool the computer. The EL GT runs the 70mm unit, same as older GT & Sprint.

On a related note you'll be happy to know the 80mm MAF seems to be running quite well in my car. I should still fiddle with some of the idle voltage values for perfect smoothness but as the computer has mostly compensated I'll wait until I see some air/fuel ratios at the Dyno Day.

Paul

Don't forget that C&L uses removable sampling tubes of different sizes to work with different size injectors. What meter are you running at the moment, 70mm?

Kon - can you tell us more about your 80mm project? Just wondering about things like where you picked it up and how much, and how you went about the installation etc.

Slap us with some info mate :)
