Apart from having the cam alignment checked to ensure it was within factory tolerances (it was, no changes were made at all) the engine is 100% factory stock in all respects. gogetta wrote: has your feul economy altered in any way?

I've been in a VCT AU XR6 and it was sticky as s**t (grippy). The bastard of a thing handled brilliantly and stuck to the road like tripple road kill. It also takes off from the lights faster than a HP, as it squats down, grips and f**k off fast. With a K&N, replacement headers, hi flow cat and exhaust, you will have yourself a bloody awesome car! If you still wanted more after that, chip it. Don't give up that sweet engine and sweet IRS just becuase the thing wont take to a cam as well as the HP. Have a chat to COREYMUNDAY if your not convinced. On typical Aust roads (not race tracks where its basically useless) the IRS is a very effective setup. I know its my preference. Bump steer doesnt exist.. which is weird as I have owned many falcons and all of them did it, it was just a natrual handling trait. Now its gone its jsut a different experiance. That said though the factory Tickford springs on the IRS were shocking. Kidney belt specials. I put on Kings SSL's and the ride got softer (although wheel travel suffered).. go figure. Oh, and with the IRS the tailshaft NEVER touches the floor with SSL's. The diff is fixed in place, no issues there.

All in good time. I wont just do headwork and cam though. If and when I touch the engine it will be a serious rebuild from the bottom up. I dont like doing things in halves lol. For the moment though I need to get some more track time in the car as it is. Its only had 6 runs in its current setup and the last 2 were the only decent ones. Another 6-8 runs and I think it will drop ET's by a decent margin. I'd like to see 14.3's before I touch the engine... or at least know I've got the best out of it as it is now.

Fair enough!!!! Im doing the top end first on mine. Aiming for 13's im running an au motor with EF ported tickford head. so it'l be a good test to see how the AU motor cops s**t lol it will be revved to 6000 regularly lol it lives at 5700 at the moment and doesnt even turn oil dark for like 3000km and uses no oil at all and i change it at 5000 so it cops it so far

The bottom end in them is seriously strong straight from the factory. Problem is the long stroke means anything over 6000rpm and the rods and pins are copping some serious stress. That said my cut out is at 6000rpm and I've hit that in 2nd at Heathcote and bounced it 5 times before I got the next gear in. I drive the auto as a manual at the track, certainly seems to help.

They are bloody tough! i dont think 6000 should be to bad for AU motors... They rev much nicer then the earlier 4L and are so much smoother! has ur Rev limiter been moved up! or is that factory! im running EL fuel injection and that cuts in at 5700. Id like to see the tacho hit the end

(Digital Dash)Its been moved up with the edit tune to allow where the shift points have moved to. Factory cut out is 5750rpm. I've seen mine go to 6300rpm on the dyno... but with a stock motor and cam that was just pointless.

How did she sound at 6300
yeah id imaging the power would have been dropping off sharply by then! Does it pull hard right up too 6000?

Stock springs dont cope well at those rpms and it started getting a bit mixed up. Power was falling like a stone after that. Currently we have a strong power range in the engine, something the VCT is good for. I havent seen the dyno sheets lately but was told (and it feels like) the power is pretty flat from about 4000 through to about 5500 or so. After about 5800 you can fell it taper of a little.

G&D Airbox went in the same time as the new exhaust and edit. I cant tell you what it was worth alone. What I will say is that everyone I know who has one wont give it back. That includes me.
I personally feel it works. That said though it was certainly an expensive setup and not something I think everyone is willing to pay for.
