Modding your AU for power and performance?

Want to know what you are really likey to get?

Here is some real average sort of numbers that you could reliably expect to get in terms of rwkw fwkw 0-100k and 1/4 mile from you modded AU Six.

Mod FWKW RWKW 0-100k 400m
AU Auto 157 105 8.8 16.3
AU 5Spd 157 105 7.9 15.8

CAI no measurable difference sorry

Extractors and 2.5" exhaust
AU Auto 165 115 8.2 16.1
AU 5Spd 165 115 7.5 15.5

Extractors and 2.5" exhaust & Mild Cam Wade 1004, JMM Dev3 etc
AU Auto 175 125 7.9 15.8
AU 5Spd 175 125 7.2 15.2

Extractors and 2.5" exhaust & Street Cam JMM Dev3HL Dev4 etc
AU Auto 185 135 7.5 15.5
AU 5Spd 185 135 6.8 14.7

Extractors and 2.5" exhaust & street race Cam wade 1521 JMM Dev5, Unichip/Chiptorque/Motec/haltech, Ported heads big valves.
AU Auto 210 170 6.4 14.6
AU 5Spd 210 170 6.0 14.2

There are lots of other mods that do and don't make a difference but I just chose a few to illustrate what can be done. obviously lower diffs hi stalls etc will make for better times but no better power.

This is a good start Jon. I think it may be worthy of a sticky as it tells it how it is.

yeah... coz of the lack of cams lol

that last one... might wanna include diff gear changes too :P

lack of cams, different base power, more weight, unusual response to some mods, horrible factory ECU programming etc etc etc. Its a totally different ball game.

Just general info stuff. It doesn't apply to everyone and certainly not to VCT engines.

Which I reckon you can get more power out of by disabling the vct solenoid and running a dev5 cam.

Just a thought for you.

I could but then I'd just have to change it all back again for the SC.
Besides, I'm betting 160+rwkw and a 14.7 is achieveble with the stock cam and some intelligent thinking. Its like a personal quest for me now.
