I recently just got a XR6 VCT and i am looking at getting more power. I would appreciate any help on what i can do and what products to use. From what ive heard its a difficult motor to get more out of?

Thanks!

Yep, its a bitch! I'm looking at a heap of different options myself for mine. Forget exhaust I think, it's just not something thats a huge success with the usual brands. I'm looking at a couple different types of extractors but have yet to get any real firm evidence that they are the go. On thing that does appear to work is a unichip to get the fual/air mix better.

Let me know how you go, I'll do the same as I discover more.

Why would you not add extractors and exhaust just because its a VCT??? I know someone who has a VCT and they added extractors and 2.5' exhaust and they were very happy with the difference.

I have spoken to a number of people who have fitted extractors and cat back exhausts to their VCT's and as yet none of them have gained any power. Sound is improved no doubt however the actual power increases have been little if none. There is a case where power was even lost.
As odd as it may seem, this is one case where the factory exhaust system is more than capable of handeling the needs of the engines exhaust. Remember that from the cat back the VCT has almost an identical exhaust system as the AU XR8.
By all means fit an aftermarket exhaust but just be aware that on the dyno and the 1/4 mile the difference has proven to be virtually nil. Sounds great but no real power increase.

Dont believe me? Feel free to PM JC or Black XR6 VCT, they have both done it and will tell you the same story.

XR6 VCT

Hi, I'm in the same boat as you guys. I brought a 2001 XR6 VCT about a month ago and I have been trying to find any mods that work on the VCT. The only one that I have found apart from the unichip is the air intake piping. But on what I read I'm a little confused, the list below is what I think people reckon works.
1, T series falcon snorkle
2, EF falcon air box lid
3, BA falcon pipe from air box to throttle body
4, some peole say change the exhaust and others say to leave it alone, just remove the resonator box at the back for a better sound
If anyone can steer me in the right direction I would appreciate it

psycho chicken

Does the BA piping fit the EF lid properly?

XR6 VCT

I don't know???? I read here somewhere that the EF pipe was better than the AU but somebody replied that the BA had a better air box to throttle body pipe.
If anybody has done these mods could they post some pictures to save the confusion

Mr Cube

T-Series Air Intak, KN Panel Filter.. and 2 1/2 inche exhuast from the cat back..

I noticed it pulls a little more, but haven't put it on the dyno yet...

It works for me..

How is the EF box lid better?

The EF one has a tube inside supposedly allowing better airflow than the AU.

Yeah, any improvements on intake cant hurt. I have the T series intake on mine too. Looked at a BMC filter but at the moment I'm not really sure it will make a hugely noticable difference so I havent tried it.
As for the exhaust, the 2.5" would sound good for sure but I think that as much can be gained just by replaceing the cat with a hiflow model and the mufflers with some nice straight through jobs. Oh, and get the H pipe removed at the tip. I have twin tips on mine, sounds heaps better.

Apart from that the unichip or XEDE chip may be the next big improvement short of a turbo.
