It hasnt made it back to the dyno, We only changed to the 6psi pulley yesterday, and I removed christians 4000rpm limit (ohh he hated that.. lol) and made sure spark and afr was all good.

Straight off the factory floor, these 315kw GT Motors pull 2degree's timing via the knock sensors. With the knock sensors disabled, the engines actually ping..

With the factory gains, the pcm is only ever pulling 0.5 degree of timing if anything, given that, there's still room for extra timing, but that wont be done until it hits the dyno.

Power wise, it would only be a guestimate. But based on how it pulls, I'd say its passed the 300rwkw mark.

When it hits the dyno, we'll see how far we can push timing with the 6psi pulley. There are 2 other spare pulleys we are going to try, based on this one we've put on, we suspect its 8psi, and 10psi (plus the original 12psi one, which struggled to make 300rwkw because of the lack of timing we could put into the already high 10.8:1 compression engine)

Did anyone see that poor bloke jogging who nearly had a heart attack when he heard Christian's car go past him? :buttrock::spoton:

Dont worry about the poor bloke jogging... On the Cruise on Saturday Night, I nearly :pooh: myself and drove off the road when he came past me... Thought I had a 747 coming in to land next to me with a bent 8 under its wings... :oops:

Forgive my ignorance, but how do you open and close the exhaust and what does it do exactly?

Thanks :beerchug:

Flap is on remote control. Basically theres a butterfly in the exhaust which either directs the gases straight through the muffler or once closed circulates around the muffler and bypasses the flap. X-force varex mufflers. Google the website and check them out.
