rob275 1817 Report post Posted November 13, 2014 This will be at 1bar at 7250rpm I believe. Share this post Link to post Share on other sites
Kodename47 446 Report post Posted November 13, 2014 75mm runs at ~9 psi, 70mm runs at ~11 psi so I'd imagine around 11.5 psi on the 69mm. Share this post Link to post Share on other sites

rob275 1817 Report post Posted November 13, 2014 that'd be 14psi .8 kg/cm2 is 11psi Share this post Link to post Share on other sites
Mark@Abbey M/S 235 Report post Posted November 13, 2014 Sounds even better. Rob can you post the video I put on facebook on here. 1 Special K reacted to this Share this post Link to post Share on other sites
Special K 442 Report post Posted November 13, 2014 Thanks Mark - ( if it 'sounds even better' get back to technicals, please.. (haha)..) For the sake of clarification - 'cos I'm an idiot - can we please quote a 'Bar/psi' comparison? I believed 14psi = 1bar. Is that wrong? (As for quoting kg/cm2...??!!??.... eh?... what anabollock steroid are you overdosing on, Rob..? ) Spec K Share this post Link to post Share on other sites

(As for quoting kg/cm2...??!!??.... eh?... what anabollock steroid are you overdosing on, Rob..? ) Spec K The abbey graph is in Kg/cm2, for clarifaction this is basically the same as Bar so the 75mm pulley is running at 0.8 bar, 69 is at true to 1 bar as you will get it. 14psi is indeed 1 bar, or near enough.

Lauren 2259 Report post Posted November 13, 2014 IIRC 14.7psi = 1 Bar Share this post Link to post Share on other sites
rob275 1817 Report post Posted November 13, 2014 A little less than that, but in the grand scheme of things it's negligible for a forum Share this post Link to post Share on other sites

Mark@Abbey M/S 235 Report post Posted November 18, 2014 Been playing again on the dyno yesterday playing with the calibration , Injector end angle and Pi versus DI ratio. now up to 300 bhp flywheel still think there is more to come with more fine tuning , think we will sort per cylinder AFR measurement out and configure our PLEX knock monitor to give per cylinder knock readings so we can tweak per cylinder fuelling/ignition out. 2 KevinA and Keethos reacted to this Share this post Link to post Share on other sites

Mark, that's gotta be 300+ if you've got 262 at the hubs... and that is an impressive torque curve (but the "ditch glitch" is still there...) What fuel are you running and what boost? Is it worth considering octane booster ? - there's mixed feelings out there. I've looked into it and I'm tempted, for next year, to use 108 octane fuel with customised 'map'. There are significant benefits. But only when I feel it's appropriate, like when I'm late collecting my pension, or the TSS spider lover/ masher from Japan are shafting me on track, (as usual...) ..hrrmph...

Mark@Abbey M/S 235 Report post Posted November 18, 2014 SpecialK Shell V power fuel. 7 lb/ft dip is that worth worrying about or smoother like a normal dyno; Thanks 3 GTB, LFA and Keethos reacted to this Share this post Link to post Share on other sites
CHOSENMAN007 81 Report post Posted May 9, 2015 Those are very impressive numbers indeed Mark. Id be happy with that. I 100% need HKS headers. I swear im running 14psi on a 75mm pulley. Got to check my data again. But think so. Share this post Link to post Share on other sites

Mark@Abbey M/S 235 Report post Posted May 10, 2015 For a track biased car I feel the HKS V2 maybe the way forward tbh. 3 GT86Jay, Ade and Lauren reacted to this Share this post Link to post Share on other sites
