I have a bit of money saved, and was talking to the teacher at Tafe, he said the EA-ED head was designed by Yamaha, and the exhaust manifold by Ford, which choked it up. The Teach said extractors are the best thing for the cross flow head, for improved performance and economy.
Wanting to know the average price of New extractors, and if second hand are any good, what should i look for?
Can anyone with extractors back my teachers statement on Extractors
i thought ford did the ea- heads. the xf unleaded heads were done by someone else (think it was honda) and then ford had a go themselves with the ea on.
Yeah, i found the pacemaker extractors and 2 1/2" sports exhaust made a huge difference to top end and fixed my cars thirst for fuel. Gotta reset yer computer tho, as i found out a month later
yeah they dont have everything listed on their site. i put the link up so you can get their contact details.
you can get a copy of parts peddlar if you wanna see more, they have a 5 page ad in there with most stuff listed.
With extractors well on my car anyway (3.9 cfi) there was no major bottom end improvement. There was a significant increase in mid range after 60 and in the top end is where the benefits are truly 'felt'. You will notice your car will be allot more free-revving as well and some fuel economy benefits if you don't thrash the crap out of the car.
My old extractors had cracked down in the pipe cluster (6 years old) so I've just had Pacemaker "Race Series" extractors fitted and I've noticed a definite increase in power and an improvement in fuel economy.
I don't know what type the old ones were but they were 2-3-1 type ones whereas these new ones are 3-2-1. I never did notice any improvement in power or economy when the original ones went on - but the difference with the new ones is definitely noticeable.
All Crossflow means is that the intake is on one side of the head, the exhaust on the other. Should be easy to see when you open the bonnet
