65mm Throttle body on 5ltr EB - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I just had an AU XR8 65mm T/B put on my 5ltr EB XR8 the other day. Mate does it have some pull now! Much better than stock!
With the pacemakers and the T/B working hand in hand, it makes a considerable difference in mid-range to top-end torque and horsepower.
Yet, there was some mucking around to make the T/B fit, it still was worth the effort. (my mechanic put it in by the way)
I admit its an expensive exercise for an approximate 5kw gain but with the extractors taking care of the other end, it worked out to be one of the best moves I've made to make the car go faster so far.
I plan to get an EL or AU XR8 upper and lower intake manifold to suit and a set of Yellaterra roller rockers, which will hopefully boost flywheel kw's to 190 roughly. I'll see how the money tree is before I do anything more within the next few weeks.

Are you sure the XR8 doesnt already have Yella Terra roller rockers. My girlfriend works there and they have been making Tickford Rockers for years, up until october last year. Ill get her to ask them tomorrow.
If you get adjustable rockers u will probly need new rocker covers. If you have Trouble installing them gimme a PM.

Good to see you are happy. ED's dont have roller rockers, the first to get them were AU XR8's although ED XR8 Sprints had FMS roller rockers. Street Terra ST2072 are the rockers you want. They are direct bolt on units and increase the ratio from 1.6 to 1.72 giving you more lift.

Well, we asked and you right, they dont have them.
What price did ya get quoted? I may be abel to get ya a better deal.

Now what a coincidence - I happen to have a 65mm TB off an Au V8 for sale! PM me anyone who is interested.

I put a 70mm one on mine, and while I don't reckon it makes any more power, it does keep pulling all the way to the rev limiter! It's also more responsive at lower speeds (ie just touch the accelerator pedal and something happens).

Get's rid of that asthmatic feeling!

I feel like I'm stealing this thread, so I've put a link in to the 'Market' section of FF, where I've advertised the TB. At least I'm not off-topic for once!
