Bf Xr6T Tune Query

[bionic_oosty]

Ciaran - yours should def have the better internals, but that's a good sign if yours is still going strong at 270rwkw.

Henz - What mods did u have for the 360rwkw tune on the stock valve springs?? Is yours a MKII?

Thanks for info ppl, it's good to know what others are getting on the dyno and how reliable car is afterwards!

[Ciaran]

Yeah mate, def has, are you sure yours doesnt as it was in the same month? (unless you're using american time/date format)

Should be good to 400rwkws or so I believe

[Henz]

Mk2, but all bfs have the same.

Has a full cooler kit, 4" dump + cat plus injectors and surgy.

Ciaran - My bad man, I just noticed I wrote 4/6/06 build.. I actually meant 4/2006 build date. Which is really close to when they MAYBE started upgrading the internals!

Henz - Yeah I just seen your list of mods in your signature.. Very nice. How bad is drivability now that it has valve float? Tuner told me it's not "harmful" to the motor, more of an annoying splutter after u boot it...

[ratter]

until it drops a collet followed by a valve, pistons and valves do not get along well in the same location if one of them is off it's leash

What ratter said.

So I says to ratter I drive like a granny. That should keep me safe.

What he doesn't know can't hurt my motor right ?

Henz do you find that the 9.5" pen*s helps alot in making that much power or is it just useful to have?

[PookeyMaster]

LOL. Probably both for him...

Ok, so got the car back this arvo. It made 326rwkw, 437hp, 690 ftlb of torque and tuned @ 14psi with a drop to 12psi.

The clutch started slipping on the dyno (4th, 5th, 6th gear on the road are useless on boost).

And an interesting thing they got from my car is that the compression was REALLY low and acted like an N/A bottom end showing its ignition timing as 4 instead of the usual 12... I don't know if I explained it correctly, maybe sum1 else knows what this means??

Or another factor they said is that it was really poor 95 octane fuel. But I told them what BP I got the BP Ultimate from and they said that's where all their customers fill up for a tune..

Either way, even with terrible clutch slip it still goes like crazy and it was an exciting drive home lol.
