Boosted Falcon

Hi All,

I'm fairly new to the forum and also to XR6 Turbos and don't have alot of info or knowledge of them. I've been running through the forum trying to find info, but I usually don't have alot of spare time to go hunting, so I thought, if you guys don't mind too much, to ask a few stupid questions that have probably been covered a million times, but for the life of I can't find the answers to. So here goes.

What boost does a BA and also a BF XR6 Turbo run? A friend of mine has a BA MKII and it's only running on 4psi and I wasn't sure if that was normal? His is manual and my BF is auto which will make a difference, but mine seems to go alot harder than his! He is having a few issues with his car though and I wanted to make sure that his boost was correct.

On the BA again, he's having a few running problems with it also. When he accelerates hard in 2nd or 3rd and then backs off, the car wants to stall and sometimes it cuts out completely. If he stops at the lights it hunts badly and sometimes cuts out! It's a manual too if that helps? Any ideas? This thing is pretty much stock too. Just had an exhaust mod to it and thats it.

One last question about the premium sound system that ford fitted as an option. Does the subwoofer in the parcel shelf run off an amp at all or straight off the head unit? I would like to upgrade mine at some point as mine doesn't seem to like too much bass at all and I have to have the bass turned down alot. It's not blown but just doesn't seem to cut it with the music I listen to. I also fitted an accesory socket to the headunit so I can use my iPod on it, but it seems to buzz alot through the system. Is this normal or should I be looking for some fault?

Thanks guys. If I remember the other questions I have about these great cars I'll post them up.

BA/BFs XR6Ts run 6psi boost stock. (I think the f6 runs 7-8psi?)

if your mate is running 4psi must have a boost leak somewhere.

with his issues, get him to replace coil packs and spark plugs.

there is a small amp for the premium sound. there is a small JVC 8" sub somewhere (check ebay) you can upgrade to and mount where the current sub is. I think its about 200$? Would need to replace the amp too. Not much room there so may have to go similar size but more powerful, unless you mount it somewhere else like the back of the rear seats.

GL!

Wrong as usual, they run 6psi through the midrange and taper off to 4-4.5psi in the top end.

What's the exhaust mod that is done?

Yep, mine ran 4 psi too (BA MK2)

My mates runs 6 (BF MK2), they are all different. Don't listen to icer and don't replace the coil packs yet. Mine had 140000km on it with the standard coils, but it would be a good idea to check the plugs, or find out the last time it was done.

If your mate can get his hands on a scan tool or a xflash3 (flash tuner) scan the ecu for fault codes. If it does have a dead coil or a dodgy one it will show up. I'd be leaning towards a throttle body clean though, sounds like the idle up isn't working properly.

You shouldnt need to upgrade the amp, I'd just buy a good quality 8" sub and see how you go.

lol @ wrong yet you say they run 6psi.

contradiction much? He didnt ask what boost per 100 revs at.

Keep us posted!

Are they actually supposed to run different boost thru the rev range? I always assumed it was a bit of creep.

The figure I heard for BA's back in the day was 5.5psi.

When I used the aux in cable there was no buzzing.have you tried turning the iPod down a bit to make sure you're not overloading the head units input? Otherwise it sounds like a broken ground connection betweent the head unit and iPod or no shielding on the signal cable used, what brand is it?

I used a DNA cable.

Stock sound system isn't that great though, I installed a head unit, speakers sub and amps after a week of usin the DNA AUX cable.

Lol @ you thinking he has a boost leak somewhere.

I'm sick of your crap advice, time to ban.

The boost will vary according to manifold charge temps but in general they run between 4.5 to 6 psi

Any1 no how to remove a tension pulley off a ef ......... Please help me!

10mm socket. There's 2 bolts holding it on.

And also my ute ran 4.575374573 psi stock. Lol

yeah i got them off there the two really long ones yeah?

Yep. There might be 3 actually been a while since I took one off. Not been much help here am I lol.

lol its alright better than nothing, ill have another look but think i got them all out is it ment to just pull straight out once the bolts are off..

Done there was one more hiding behind the pulley, Thanks heaps!

Thanks For the help Guys.

We've discovered that the gasket between the turbo and exhaust manifold is non existant and the lower r/h nut and stud ( that helps hold the wastegate bracket in place) has either snapped off or fallen out! So I think we are now looking at removing the turbo and checking out whats going on. Might do either a turbo upgrade or mod the standard while its out. With the boost issue, it will be a constant 4psi then rises to 5psi when pushed really hard- the opposite to what you guys have been saying. I've had turbo cars before and ususally they will peek in boost before it bleeds off pressure higher in the rev range but this car does the exact opposite.Needfordspeed, the exhaust mod is a 3" system from the cat back. Nothing to flash and it drops out 1 muffler to give it a bit more of a bark.
Once we've sorted out the turbo side of things we will be doing spark plugs and giving it a major service. I think this car needs a bit of TLC which unfortunately it hasn't had much of. Hopefully we will get this thing sorted out.

So an 8" sub is all they have in the back parcel shelf?! I was told they ran a 10" but they couldn't confirm that. Thanks for the advice. Might have to re-evaluate my thoughts and ideas on the stereo set-up now.
What are your thoughts on intercoolers? Particularly the ones on ebay? There is one that they are selling for $200 as an upgrade and it looks ok but not so sure. I wouldn't mind upgrading the cooler and flash tuning mine down the track but want to make sure the parts I use are reasonably good. Just because the parts cost the earth doesn't mean they are the best around. Same goes for the cheaper varients. Just because they are cheap, doesn't mena they junk. What are your thoughts and views?

Oh and laurasXR6- Open your own post next time instead of trying to take over mine!

the car does not use a gasket between the turbo and manifold, the cheap coolers, although flow well, do not normally cool well, which is the job of the cooler, you get what you pay for

I had an F6 that shat one of those bolts out a while ago. Also thought it was weird that there was no gasket, only to find out they don't actually have one fitted from factory. Have heard of some people warping the flanges and then having to fit a gasket to get it to seal properly. The stud and nut is about $15 from Ford.

While you've got the cover off tighten the rest of the bolts to factory spec.

Sure about the gasket? My ute def had one. Maybe it's an early ba thing tho.

yeah as sunny said those bolts fall out pretty often.. was part of servicing at Ford to retension them. Get some carby cleaner into that throttle body and get the KAM reset and the idle up issues should disappear, might even have an old style TPS on there, was a recall at some stage and they upgraded the TPS to counter those issues

So how long is Icer banned for? I'm new to this forum but I cant help but find his dodgy advice on issues for the XR6T...... Is it life ban?

yeah the sub is an 8". i swapped mine to a pioneer 8" free to air sub.was alot better.

none of my turbos have had the gasket between the turbo and manifold.and i had a early ba aswell

also instead of carby cleaner, call ford and order combustion cleaner. you spray it down the manifold, all over the tb and let it sit for 10 mins then start the car up.its pretty good stuff, very very strong. cost about $13 a can i think.

also if your after parts im selling a f6 intercooler, bluepower airbox and f6 airbox if your interested pm me.

there is no gasket between the turbo and the exhaust manifold. I had a leak (loose bolts) few days ago which i fixed and i could see there was no gasket.

for once you are right!!!

dont lie icer you didn't touch a spanner.
my mates 80k ba ute killed it's turbo and it had a gasket when i pulled off the turbo.

i actually called up ford the other week regarding it to confirm what my tuner told me. There is no factory gasket between the turbo and the exhaust manifold.

strangely enough some did some didnt.. I should know I spent a few years servicing them! didnt make a difference the bolts fell out fairly often if the cars were thrashed
