Anyone got that cool valve spring video of inside the motor revving to 10k?

That sh*t is Cooool....Man!

12 months of 300rwkw, starte to go not long after tuned to 360/16psi, replaced them not long ago. They weren't showing symptoms that I could see, did them for piece of mind and so I can push more boost eventually.

Anyone know the part number for BF springs?

Why?

probably a lot dearer than something aftermarket that will do the job better in a boosted car

Its not just factory springs that go soft, I had some aftermarket springs go soft after about 20,000k's.

They were from a Tuner in melbourne and they were also just about the only option at that point in time...starts with N

BF series Phoon running 350+ rwkw since new, now 80xxxks.

Dynoed every service and still seem to be holding up

I put xr8 valve springs in my BA because I scored them through work. According to the workshop manual they are 1/3 stronger than stock. Trying to figure out if they are the same springs used in

BFs but the part number for BF springs seams to be unnobtainable
