Taz_Rx Posted June 15, 2008 Author Report Share Posted June 15, 2008 Skids will have to wait till after dyno tuning, plus I'm not doing it on semi slicks for the sake mof a vid, so i'll have to dig out some dried old crusty 165 or something for that. :lolcry: Quote Link to comment Share on other sites More sharing options...
untubbed_20 Posted June 15, 2008 Report Share Posted June 15, 2008 (edited) Yeah alright then, I'll invest in a 12v coil soon.Plan on rigging up some sort of dualpulse CAS and running 4x coil packs eventually.  Just took it for a drive!!!! :lolcry: Didn't like 3rd too much once the boost built up a bit, but 2nd wasn't too bad. f@$k ALL LAG!! :y:  multi-coils is not really worth it, just easier to get a old MSD 6A CDI or crane hi-6 CDI etc, will have a way higher spark than a multi-coil setup and be cheaper/easier. Those old school msd come up for around $200 s/h.. bargain if they work  I have just taken multi-coils of the skyline and gone back to single coil, YOU WANT ONE??? I went back because i needed a CDI and a single coil one is around $400 a multi -coil reliable one(m@W/autronic 500R/motec) is $1400-1500. And the vl's make around 1000hp with a single coil/CDI..good enough for me.  I never has any breakdown with 23psi with the plug gapped down with a single coil etc a CDI would have been my next move though, probally worth 10-20hp at the motor anyway. cheers darren  PM me if you want a coil, they are usually $50 each, but I'll give you one in the interest of seeing this thing going properly :cool:, ha,ha they are bosch HEC 715's Edited June 15, 2008 by untubbed_20 Quote Link to comment Share on other sites More sharing options...
madrolla68 Posted June 15, 2008 Report Share Posted June 15, 2008 (edited) Sorry Si i forgot you are only running candlepower ignition.that tune was AFR 14.3 at idle and AFR 11.8 or lower on max boost so yeah it maybe not liking the ignition setup. Â Go and buy yourself a Crane HI-6 ,youll love it and like darren said,i have never had a misfire issue and they have also got a real nice softcut limiter in them.

Felix Posted June 15, 2008 Report Share Posted June 15, 2008 Taz are you running identical injectors and fuel pressure to what madrolla was? Quote Link to comment Share on other sites More sharing options...
madrolla68 Posted June 15, 2008 Report Share Posted June 15, 2008 Taz are you running identical injectors and fuel pressure to what madrolla was? Â I'm not sure about that,i think they are close on the injector size and yes same fuel pressure,he has different comp and cam though i think.

NickZ Posted June 15, 2008 Report Share Posted June 15, 2008 As for multi coils not worth it? sorry but that just isnt true, M&W in sydney make a kit that not that expensive and is capable of killing you 115mj output it increases the input voltage 400 volts. with one of these on a rotoryincreased the HP by 30% as we could add a shit load more fuel because of the stronger burn, to get that power out of a dizzy cap you would be melting rotor buttons and dizzy caps. Â Also the multi coils wont get to saturation like a single coil at peak revs, you don't have to worry about spark jumping with hi power like on a dizzy cap at hi revs (like ive seen before DETONATION). Â Multi coil setups are worth every cent for performance. Quote Link to comment Share on other sites More sharing options...
untubbed_20 Posted June 15, 2008 Report Share Posted June 15, 2008 (edited) On a piston motor, a multi coil vs a dizzy with a CDI , the CDI system will be better. Â A multi point with CDI would be the best no doubt, and for the extra $2000+ it would want to be we are talkingabout a K motor here, they ain't worth every cent. Â rotarys are another kettle of fish, they have very poor ignition systems, and need a better ignition source than most motors, especially with the fat afr's you have to run to keep them alive. Â Any link to the MW stuff, i have a PRO-10 MW CDI on my car, I can't see how they do any thing better than that, except for there drag units, would love to have a look if they do something else, as it would be good for water injection setups:) Â cheers darren Edited June 15, 2008 by untubbed_20 Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted June 15, 2008 Author Report Share Posted June 15, 2008 Yeah I've got 315cc 7mge injectors the same as Madrolla and fuel pressure is also 30psi Felix. However, my reg is a 1.7:1 RR. Been worndering if this is and issue now. Â Took it for another quick drive today to maccas, and ended up sitting in the drive through for ages,....and fouled another set of plugs!! :lolcry: Only just made it home! Thinking I might also put some new plug leads on it aswell, incase one of them is farked. :y: Quote Link to comment Share on other sites More sharing options...
NickZ Posted June 15, 2008 Report Share Posted June 15, 2008 (edited) M&W Ignitions  I'm unsure what you are doing, Why can't you just lean out your idle and lower load fuel values? Edited June 15, 2008 by NickZ Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted June 15, 2008 Author Report Share Posted June 15, 2008 (edited) I've tried nocking the fuel down a bit, both in the map and the overall trim. Seems to run well were it is, its more like the spark just can't deal with it and fouls up the plugs! Â I'll have to wait till next week when I get paid to get it on Sherriff's rollers. Can come play in the mean time if you want!? :y: Â Oh yeah, well I am gunna need at least a new coil Darren! :lolcry: Edited June 15, 2008 by Taz_Rx Quote Link to comment Share on other sites More sharing options...

NickZ Posted June 15, 2008 Report Share Posted June 15, 2008 Have you taken the resistor of the coil yet, It will be ok without it, ive used them for years without the resistor on 9v coils :lolcry: Quote Link to comment Share on other sites More sharing options...

Wil get some new plugs, leads and coil later in the week. And will go see Mr Sherriff shortly and book it in for next Thursday (26th).
