I have all the add on goodies already installed. I would like more torque and maybe 320ish rwkw.recommendations?

qik1 Silver Donating Members 2,720 Member For: 16y 11m 1d Gender: Male Location: Loitering in SEQ Posted 30/01/09 05:20 AM Share Posted 30/01/09 05:20 AM I think qik1 has pushed some boost through his beast in the past.I have had 21 through it but ive been running around on 17 - 18 for a while now but its gonna have 20-21 back through next week when its retuned. Mines a bf mk2 though.Build date was 06/06 when they went to the typhoon internals.As for more boost. Always a risk involved but blokes like blueboost & headsex have big power running through theres but im sure there willing and able to live with the consequences when/if they go pop. Some have gone bang with alot less but then theres ones that just wont die. As im sure you'll be told at your own risk. For me its worth it but would still if/when it gives up the ghost Link to comment https://www.fordxr6turbo.com/forum/topic/54032-max-boost-on-stock-bottom-end/#findComment-813374 Share on other sites More sharing options...

If you have a really strong tune and someone fills it with 91 octane (wife or friend for example) The next time you put your foot down there may be a nasty sounding bang...
