Modding A Bf Xr6t

[asromanut]

Hi all,

Im in the process of running in my BF XR6T, have done 900kms so far. This being my second T all I can say it is a dream to drive, I got the ZF 6speed auto as 1 of my options

My questions are related to the modding potential of the BF and the 6speed auto.

The mods that I am considering are as follows:

1. Custom Edit

2. Bigger injectors

3. Valve springs

Im not looking to have a monster all I want is about 280-290rwkw, and have the car tuned for mid-range torque, what torque figures should I expect with power such as I have descibed?

Would I need to have the auto modded to cope with the increase in power and torque?

Also considering the power that im after is there any mods that I have missed and should consider?

Who is the best tuner around? Ive heard lots of good things bout HPF and Nizpro.. im in Melbourne

Any advice to steer me in the right direction would be gratly appreciated!

regards

Mark

My first concern would be the new gearbox.

It has been rated to 600NM, which you will exceed easily with the modifications you have outlined.

Unfortunately being a new component, there's not much data on what torque levels will actually kill it.

well if they can up firm up the shifts and increase the line pressure, the box should be fine...the 4-speed auto is only rated to 450nm and with an Edit it could cope just fine with the power you want...so I don't see any reason why the 6-speed auto couldn't cope with ease...

I would also get one the bolt in intercoolers to keep everything cool...

Dont think the Edit works for the BF yet..... something to look into !!

Wrong Street tuner has already stated that the Edit has been done for the BF

I heard this too but I also heard that they couldn't control the new auto...

any fact to this rumour?

This is the exact reason why im waiting to see some bf auto t's on the road and tuned otherwise I would have one on order now. The ion four speeders seem to handle a high amount of torque once the shifts are firmed up. bty the ion four speed auto can handle max 520nm although the torque reduction nobbles a lot of that from idle with wot.

Hello Mark, the BF responses very similar to the BA except for a little more torque in off boost conditions and it comes on a little sooner, power levels are also similar. We haven’t done enough BF’s at this stage to believe that peak power is much better than a “good” BA.

The ZF6 does run a separate PCM and there should be access to it around March/April 2006 in the mean time I believe it will handle your power upgrade as the 600 nm torque rating is measured as an endurance figure meaning its peak torque load will be quite a bit higher.

I realise that the peak torque that ZF6 would be able to handle would substantially higher than the 600nm its rated for.. but at what cost? Im looking to have something that is tuned reliably without having to worry that the torque will fry the box.. My dad owns a Jaguar S-type R and it has the same ZF6 speed as the BF does, not sure on it torque output but it has 300fwkw. Does anyone have any info reagarding the reliability of the ZF6 because alot of euro cars have this same auto and deal with much higher torque and power loadings

Dude, you're just gonna have to wait for the info you're after. I'd certainly wait until some tuning houses have played with the ZF6 box, rather than offer yours to someone to experiment with.

Nizpro are right on top of BA/BF Edits etc as are others. Keep your ear to the ground, but no one knows just yet. You can bet they won't keep quiet about it when they do.
