Fg Xr6 Turbo Questions

[PAH]

Hi Guys,

I've knocked up 1200 kms. XR6 Turbo power is lots more accessible than the old SV8 . . . and there's more of it. I've never met a kilowatt I didn't like . . . at least not when I'm behind the wheel. It's not much fun being a passenger when the driver is more interested in being a hero than alive.

I understand that Ford started fitting Typhoon bottom ends to the BF and FG XR6's. What does this include? Stronger rods? cranks?

The FG runs 10lbs boost. How much when it hits overboost?

Ford said they will check out the transmission noise at the 3000k service and indicated they might be able to make some degree of improvement. This noise is ALL diff bushes?? Or does the noise come from other areas too? What does Ford to to reduce the noise?

Ford lists the oil change interval as 15,000 kms' That sounds a bit much to me. I plan to drop it every 7500 kms. I've got some Shell Helix Ultra (5W 40) that I plan to use if it meets XR6T specs.

Removing the centre muffler and fitting the XR8 air box - does that make a noticable improvement in power? Academic question. The car feels strong enough to me as it is.

Typhoon bottom end

Overboost

Whats the noise sound like...

Ford Doesn't Recommend 3000k Oil Change?

Yes.

Only difference was stronger conrods and better valve springs.

This will not meet the specs as if you consult your owners manual you will find you need to run a 15w/40 oil. That's if you want to keep your warranty.

When I fitted my lower airbox and snorkel I gained 11rwkW. Not sure about the exhaust although it does make more noise. There is a thread in the Exhaust section with film clips of someone who has the centre section of the FG XR6T removed.

Thanks for the info,

Ford lists 15W-40 engine oil. It's my understanding that the wider apart the two numbers, the greater the protection. 5W-40 engine oil is superior and the extract below explains why:

A 5W-30 motor oil performs like a SAE 5 motor oil would perform at the cold temperature specified, but still has the SAE 30 viscosity at 210° F (100° C) which is engine operating temperature. This allows the engine to get quick oil flow when it is started cold verses dry running until lubricant either warms up sufficiently or is finally forced through the engine oil system. The advantages of a low W viscosity number is obvious. The quicker the oil flows cold, the less dry running. Less dry running means much less engine wear. http://www.upmpg.com/tech_articles/motoroil_viscosity/

With this in mind, I doubt that Ford would have a problem with me using 5W-40 engine oil, but I will check to make sure.

It's not hard to see why Ford is able to specify a 15,000km service interval! The engine sump holds 7 litres!

The article I quopte above was a bit of an eye opener. Maybe it explains why Mobil 1 is a bit more expensive.

If you run anything outside of what Ford specify and have an issue, good luck with your warranty claim.

All good with better oil flow when cooler in temp, I would think though if you was to WOT your

car before it was up to temp it would cause harm due to the loads being to great for a low vis oil.

I think Ford recommend that spec for that reason.

It will come down to how you treat your car to weather it would be safe or not.

If Ford have set oil changes at 15 000 why not just buy the oil from them at 7500 and do

a mid change in between services, my choice would be to change at 5000k's.

I know what you mean by 15 000, its a lot concidering I do my changes at 5000 and I use

Syn not a minerial as per ford.

If you do change to a non Ford oil make sure you stay with what ever you use and have Ford do like wise.

I would change to a Full Syn oil at approx 20 000k's if it was my car.

What trans noise & when?

Is car Auto or Manual?

If the later get use to the noise as it comes with the manual. doubt it would be any bushes.

The impression I got from someone I know from the geelong engine plant was that as far as FG is concerned Ford and FPV bottom ends are not the same. We were chatting about mods and he suggested it was a much better idea to start with the FPV turbo motor due to the lower tolerances in the Ford motor.

[PHANTMXR6]

Sounds bogus to me.

[bunna]

why? It was only the former engine plant manager I guess. Maybe I got my wires crossed?
