Sweet, thanks dude.

Are you ap1? stock internals?

bruthaboost

May be upgrade your valve train. I got valve float on the dyno and really would of appreciated having that upgrade done before that happened OR you may be fine. However, for 350 usd and an afternoon or wrenching, I thought it was an inexpensive and easy upgrade.

valvetrain ?

valves, springs and retainers?

What do you guys use for these? Ferrea (im an audi guy and i used Supertech on my last build, but Ferrea seems to be a little better quality) ?

Any links of where is best to buy this stuff?

bruthaboost

My tuner recommended supertech, the 95lb seat pressure (IIRC) dual spring set up and he has been spot on with everything he's told me. Just FYI, their retainers are snap fit as well. Not sure where would be best for you to purchase since you're in Aus. I picked up mine from THMotorsports. I've purchased plenty from them and they've always picked up the phone.

Redline S2K

I'm pretty sure JJ is stock motor.

jcolossal

is there any lists that have been compiled that show peoples power/torque figures to length of time at those levels?

Redline S2K

Yes. At the top in the Stickies, there is a thread called power charts. Doesn't show how long but if you search there names, you can find a build thread and see if they are still running.

jcolossal

Yeh i did have a look at that already, I just wondered if there was a list with length included.

It seems guys are putting down crazy power, but for how long?

Reliability is big in my books.

On my motor, which is stock bottomend, and head has supertech springs and retainers and valve seals i made 480 on pump gas which is 93Octane, then 559 on race gas C16 with a 6266 turbo. I've never had a problem with Supertech products. Nore have any of my customers. Now i hear the econ valves people were using were the problem. Let us know if you need anything sir, we ship overseas as well.
