Im getting some work done to my T (finally) and I got a friend who has F6 valve springs, I just wanted to know what power output they can handle and if they would be good to put in the T. Or would it be better to get a brand new set and get them fitted? I prob wont run more that 300rwkw max on the car.

open to any feedback

if your doing the springs, pay the 250 odd so if you want to mod any further down the track, they won,t hol you back. just my opion

My experience was it let go at 390rwkw. (BF F6 Auto)

Though I have heard of the valves springs being unchanged in a manual phoon with 500+rwkw

nizpro told me bfs have typhoon springs already in them they are good for 380rwkw then you upgrade them but if you have a ba you will have to do them staight away after a couple of edits .

My springs go all funny after a few hard hits , hate to see what real power does to them . 300 + seems to be the change over point , otherwise the collets and retainers will get hammered as well .

Mine are still standard at 500odd rwkw's.

Simons ar XFT are standard at 534rwkw's.

They are fine.
