barnz Member 3,047 Member For: 11y 2m Gender: Male Location: Brisbane Posted 23/08/15 08:27 AM Share Posted 23/08/15 08:27 AM I would think raising the comp is going to make it not 98 friendly....you sure you want to restrict yourself to high octane fuels? Low 9's shouldn't be too bad though...Sent from my GT-I9300 using Tapatalk Link to comment Share on other sites More sharing options...
