Extractors for AU VCT ? (no jmm race series anymore)

Autocade · 07-03-2006, 12:47 PM

Hello to all the AFF AU family

This being my virginal thread post on this great forum please be gentle on me.

After months of waiting for a new production run it appears the JMM race series are to be (unofficialy from what im told)no more.
So what to do now for extractors to suit the AU VCT I6?
My research so far has concluded that some can have negative results and are basically a compromise when compared to JMM race series.
With the fitment of a 2.5 Redback catback system gaining IMO no noticeable power increase at all do I even bother with anything else?
I know this has been covered before but the AU VCT appears to be very unresponsive to exhaust changes and these were the only ones with proven results on the VCT.

Please Help?
Thanks in advance

Get some pacemakers they worked for me. Before and after dyno results in the gallery. Work on VCT too check the SA dealer website for a before and after on and XR6VCT ute

Autocade · 07-03-2006, 02:24 PM

Thanks Jonbays
I'll check them out

I HIGHLY recommend getting JMM streetfighter headers. I have a VCT, with them and the exact same cat-back exhaust as you, and cant rate them highly enough. I was told by Brendan (works for JMM) that race series wont be much different to the streefighters, and he was right, excellent power gains (not proven, just seat of the pants feel)...

I too have streetfighters on my VCT. My car was Dynod @ 127 Rwkw with just extractors and exhaust. Stock VCTs are anywhere from 110-115 Rwkw so there are certainly some good gains to be had with the correct bits.

Having said that , PH4480's from pacemeker seem to have very similar results.

Its now a choice between Pacemaker comps (similar to JMM Race headers) and JMM Streetfighters.
I'd get whatever is cheaper and easier to get hold of. Both will be very similar in performance.

Autocade · 08-03-2006, 09:24 AM

Looks like some more research required and a new choice to be made
I am even thinking possibly going Edit rather than Headers as it might be more bang for the buck
Thanks to all for your replies

Headers will give the biggest gain (short of boost of major engine work), you will most likely be dissapointed going edit before headers, IMO, it should be the other way around...

Autocade · 08-03-2006, 10:13 AM

I certainly wont be jumping into edit without thoroughly researching first but it is IMO worth looking into as an option.
It appears headers achieve some modest power gains but is it low down or more up the rev range where I reckon the VCT is not too bad anyway
I am trying to achieve more down low rather than cruising gains which might be achieved with edit alone

If you want email or PM me with your concerns. I have gone through all this with the VCT before and have found a "path" to follow that should see some interesting results

Ask around as well, youll probably get pointed to me in the end anyhow LOL.

Also, speak to Racecraft and JC, they have also has experiance that may be of help.

cArSiK · 08-03-2006, 05:00 PM

As Casper said there is a process that needs to be followed. I Followed Caspers 'Path' and couldnt be happier.....Casper why dont you start up your own VCT tunung House and make abit of money from your formula- 'Casper VCT Motorsport'

Thanks all for your replies
Casper is JMM your workshop?
Reason I ask is that I tried a set of their Autolite plugs out recently that were supposed to gain an instant 4kw and noticed no difference (IMO the stock denso iridiums feel better) consequently I am not convinced they are the right shop for my VCT now I cannot get their race series headers.
It appears you may be the one and only VCT guru

Casper and JMM had a falling out, I'll let Casper explain. It's probably rule 1 of business.

Try the Pacemaker PH4480 headers for your VCT, which happen to be the Comp headers for AU I6s. When I first got them on my ute (non VCT), I noticed it wanted to rev more, and breathed alot better than it used to. I'm sure it would have some big change in the VCT engine.

duaned · 09-03-2006, 10:12 AM

I have used the Paccie comps and currently have the streetfighter headers on my Falcon and found the exhaust note to be slightly deeper on the streetfighters. Performance seemed to give a slight edge to the streetfighters.By the way mine is the VCT also.

We highly recommend the Pacemaker competition series in 1 5/8 inch for the AU.Our testing has shown this header to be far superior over any other.

Did your testing include the AU VCT engine also?
Could you please send me information on the engine type I6 VCT etc and which Header brands you compared in your testing and the actual results

I am now exclusively using G&D as they are by far the most advanced in the VCT area these days. JMM simply never kept up R&D on it and it show. G&D have moved so far ahead now that no one is close to them as far as the VCT goes.

Talk to Glenn or Matt at G&D. Just dont ring them Sat Morning.. I have work for them to do

Can anybody explain to me why motiviator headers havenot ever been mentioned as fitment to anybodys cars?
I had them fitted to my first xr6 eb with 2.5inch exhaust and the thing gained so much more power and torque
would they be the same on a auII ???

Most likely they would be good on AU's if they are for EB's, but VCT have proven to be a different kettle of fish. DO a search on VCT exhaust and you will see the arguments for and against various brands...

Personally though, ive never heard of motivator headers?? :nutsycuck
