was 3 quick runs
nah it wouldn't... the 3rd gear pull would be like ~3wkw more assuming all things equal...Quote:

yeah i was agreeing with you... but his higher 108wkw reading was done on 4th gear at Mercury and his lower 92wkw reading on 3rd gear at the other place was erading lower...Quote:

lower the gear, lower reading?Quote:

maybe... i noticed a huge response difference between a metal mesh pod (like blitz) vs a foam pod (obx) that i had which all FELT zippier on a cai versus an inverted gauze k&n extreme.Quote:

But yeah not a 17wkw difference... unless he does the dyno at Mercury again we won't really know for sure as it could be that Mercury's was naturally reading high (or vice versa)... his 92wkw at the other dyno would possibly translate to 102wkw at Mercury again at a ~6wkw loss which would support the intake change idea... he also stated above that theres only a noticable power difference and definitely not 17wkw...
Most of us here who drive NA's will know that 17wkw is a huge noticable difference... you would all also agree that even putting an intake on will be noticed by our @rses and their worth anything from 2-8wkw depending on other supporting mods...
oh well new dyno comp on the 30th at different dyno if i can get a spot it will be interesting. This time will be with the filter
i'll keep yous posted and after that might be back off to mercury motorsport and test it their with both filter and no filter
bloody dyno comps what shits me is that i cut a hole in my bumper and mounted a bell mouth in it to feed the intake and it done nothing. oh well at least it looks good imo
