Can anyone tell me if I fit extractors to my car (AU1- stock 6) will I get any real benefit other than a nice tune? Also I've had it suggested that I fit a Tickford snorkel and an EF air box lid. Again, what will this achieve for me? While we are at it, anyone got a good, cheap set of used extractors for sale in the Brisbane or Ipswich area? Thanks people.

A good set of extractors (small primaries) and 2.5in exhaust with snorkel and air box will give you a small increase in power, but not much.
The changes to air intake will help your engine breathe better at mid to high RPM's, and the zorst sys will sound better than standard, so all in all you'll feel like it goes better, and feel better. BUT mostly in your mind, which is for a good feeling, so go ahead

go for it. 16.2sec 1/4 mile in January....15.8sec on Saturday. The only thing i did was put on a set of extractors. Pacemaker to be exact. i didn't even do the whole system and thats how big of a difference they made.
Just take off the old ones and you'll see how restrictive they look.

i havent yet put extractors on my car, but plan to put pacemaker - tuned length ones on...

I have done 16.06 down the qtr without them... and before that, i did a 16.6 with only mods being an K&N Panel Filter, XH Air Intake, and 2 1/2 inch Cat back exhaust. Plus my car had done a touch over 200,000k's at that time.

UNR8D said after he put extractors on his car he definitly noticed a difference all round the rev range.

There are some serious power and torque gains to be had with a set of Pacemake PH4480 small primary extractors on an AU see my gallery dyno comparison on my AUII to see what you could expect to get at the back wheels.

Ive got Hi-Tech extractors(same design as those used by Jim Mock) and a 2.5" exhaust on my AU, as well as the tickford intake and EF airbox lid and it breathes sooo much better. Ive picked up alot of low end power from them. The difference between my car and my dads stock AU when i put my foot down is amazing! I recommend you do it mate.

Cheers,
Brad

As others have said extractors willhelp with low down torque, as well as helping the engine breathe better at higher revs. I have Pacemaker 4499 on my VCT XR6 and my AU2 wagon. The XR puts around 10% more torque than an equivalent standard XR, while the wagon is really noticeable for the extra driveability gained after fitting just the extractors (with standard exhaust system).

The 4480 are a longer secondary pipe than the 4499, but I was told that on the AUs, this can cause problems with the Cat converter and O2 sensor, so be careful if you choose the 4480s. The 4499s are proven on all non-VCT I6 AU falcons.

Visit the pacemaker site at www.pacemaker.com.au (it's new).

I have High techs(JMM Series 1), Pacemakers are not bad, just stay away from Genies.
:(

JC interesting comments on the 4480 versus 4499 Pacemakers. Do you have before and after dyno runs on your car with the 4499 to compare with mine with the 4480. it would be an interesting comparison and clear up where the differences are.

I have the standard JMM headers on our AU, however we modified them to have the same (long) length secondaries as the JMM race series, which I put on the ute. So far I haven't noticed any problems with the AU.

The secondaries are around 350mm long.
