Guest rallyeluke Posted June 4, 2014 Share Posted June 4, 2014 it is a well known common myth that cone filters work better on turbo setups then they do on nasp setups (no doubt due to the very black and weight understanding of "more air means more go") I imagine that is why they chose that car and that engine configuration. in all honesty MCM are not the only ones that have dispelled cone filters with science and data but there you go In a reality a HONDA needs a open induction setup of some kind so you can hear that filthy metallic angry VTEC noise Quote Link to comment Share on other sites More sharing options...
Dougie Posted June 4, 2014 Share Posted June 4, 2014 indeed, also i wasn't particularly talking about cone filters, just the cold air feed, most people will agree that the best setup is an oem dc2 air box WITH a cold air feed (i however don't personally have any experience with them so can only go on what other people have said) Quote Link to comment Share on other sites More sharing options...
Krzys Posted June 4, 2014 Share Posted June 4, 2014 I need to run a feed to my airbox but otherwise it feels nice to drive! Quote Link to comment Share on other sites More sharing options...
Jayhoath83 Posted June 5, 2014 Share Posted June 5, 2014 it shouldnt make any difference between 95 and 99 if your engine cannot actively utilise the fuels added ability to resist pre detonation, if you advance your ignition timing to utilise the added protection of higher octane fuel then you will notice a benefit but if your engine doesn't have a knock sensor or you dont manually adjust the ignition timing through the dizzy it will make no difference. All b series have self learning ecu's so they do benefit from higher octane fuels Quote Link to comment Share on other sites More sharing options...

Guest rallyeluke Posted June 5, 2014 Share Posted June 5, 2014 In reality any mpg benefits you may see will almost certainly be negated by the additional cost of super unleaded over conventional pump gas, if you are really interested in getting the most out of higher octane fuel the only true way is to have the vehicle mapped effectively to run on higher octane gas asany ecu fuel trim and ignition curve adjustments will only be made within the ecu's very limited closed loop functionality. And if the B18c4 doesn't have a knock sensor it has no way of actively adjusting ignition curve so it cannot utilise higher octane fuel unless you adjust dizzy yourself. How well does the B18c4 respond to ignition advance? On my D16a9 powered ed7 91 civic it loves advances and you can run full advance off the dizzy and it does not det, B series is quite fragile I head in regards to detonation Quote Link to comment Share on other sites More sharing options...
Jayhoath83 Posted June 5, 2014 Share Posted June 5, 2014 I think, so dont quote me they are +15deg but cant remember of the top of my head n ur forgetting that the b series was designed to run on higher octane fuel as thats the norm in japan n thats why they do respond better to it n im not saying it will give u more power but the higher the octane the cleaner the burn which inturn helps the engine stay cleaner in the head n bores which is never a bad thing Quote Link to comment Share on other sites More sharing options...

Jayhoath83 Posted June 6, 2014 Share Posted June 6, 2014 Already have m8 n ur sort of right but no one is talking about engine knock as none of us are running that high of octane level to cause such an issue n as said these engines were originally designed to work with japanese 100 so using 98 in the uk or even 100 is not going to hurt the engine Quote Link to comment Share on other sites More sharing options...
