Re: AU2 Xr8 mods advice

Andrew,

Check out this thread:
https://www.fordforums.com/showthread.php?t=42967

I have (had) the same engine as you and I was very happy with this combo. Note that the engine did seem a little more sluggish than stock when running under 2500RPM. Not too bad mind you, and it might have just seemed that way because it came on with a real rush after that. I had a manual trans, so a slightly rough idle did not bother me.

Matt.

Re: AU2 Xr8 mods advice

Remember there are other grinds out there, probably better suited to auto's.
The 2031 is a good auto cam but will require 1.7:1 rockers.
So check whats available for 1.6:1 rockers with characteristics more like the 2031, like crow cams,etc
Also do a search and see what the boys on the corral forums are using.

Cam and valve springs,etc....for sure.

Re: AU2 Xr8 mods advice

Apparently so far I have gathered for the au 2 xr8 200kw spec the Crane 2030 is the cam to go for. With springs retainers to match, is there anything else thatshould be replaced at the same time ???



And does anyone have this cam in a Au xr8 auto and has a sound file of it they can either send to me or put up here.

Re: AU2 Xr8 mods advice

Might want to change the timing chain/gears with a decent rollmaster one while everything is out, otherwise everything else should be fine I think.

Re: AU2 Xr8 mods advice

Ok so the list is at

1) Crane 2030 Cam (is this the best cam for the job)
2) springs to suit
3) retainers to suit
4) Rollmaster timing gears/chain

I would add valve spring retainers/keepers. Remember gaskets, and labour too.
I would also look into other cams, just to make sure it's what you want.
Best to make an informed decision, as they aren't the easiest things to change.

I'm not all that cluey about the internals so i am basicly going off what you guys are saying. so as far as looking at other cam specs it would be just that I would be looking at them but not knowing what the figures mean etc.

Re: AU2 Xr8 mods advice

The 2030 cam will give a rougher idle compared with the stock cam but it should still be fine with the auto. I really don't think there will be much difference between the 2030 and the 2031, but if anything the 2031 will be slightly better at idle. These cams have been well tried in the US and have always produced good results. Others you could consider are the Crow 621371 or 621417 which have also been well tested in Australian V8's.

As I mentioned to you previously champ, I still say that changing the diff gears in my car was one of the best mods I had done. Made the car feel more toey all round.

A different cam would be great, but I still think you may be unhappy with the go off the mark.

Ultimately go with what you feel is best for you and then you'll be happiest.
