speaktobrett Member 38 Member For: 15y 5m 8d Gender: Male Location: Melbourne Posted 02/02/10 05:05 AM Share Posted 02/02/10 05:05 AM (edited) Hi guys,I'm interested in doing a few mods to my BA MKII XR6, that won't negatively effect my fuel efficiency! So far I've done the Typhoon CAI. I noticed more low end power, which was great! I know extractors chew through more fuel... so I'm kinda steering away from getting those installed.I've been told that custom tuning my car will give it more power and better fuel efficiency. Is this correct? Or just people talking sh*t?Are there any other mods that can I do?Cheers,Brett Edited 02/02/10 05:06 AM by speaktobrett Link to comment Share on other sites More sharing options...

Would assume they would be similar at this rev range though. Link to comment Share on other sites More sharing options...

rockafellqeinstien Member 325 Member For: 15y 9m 1d Posted 10/02/10 06:05 AM Share Posted 10/02/10 06:05 AM I found that technically you might get better fuel ecconomy but in reallity you wil get worse because you use the new found power more (I reckon mine imporved by 5% but really I get 10% worse because I use the power more).But if you use it to convince yourself to do an upgrade go for it . hey - its how I got my motor bike - to save fuel "cough" Link to comment Share on other sites More sharing options...

Do they consume more petrol?We have 3 n/a BAs and mine is the only one with a PowerBond underdrive installed. The power increase is hardly noticeable although when it comes to economy, I am getting 30-40 more KMs out of a full tank. It doesn't seem like much at all, but does help in the long run.What kind of estimated rwkw's would I get with these mods? - K&N- Typhoon lower snorkel- 20% Under Driver Balancer- Custom tuneI also remember looking into figures while keen on modding my n/a. I can't remember the website that gave estimates and I'm not sure whether it was at the rear wheels or engine. Link to comment Share on other sites More sharing options...
