Was looking through the COZ website and found this: http://www.conceptzperformance.com/...Car_Type=300&UID=20080908013727130.95.196.250 Is anyone using one of these and have they noticed any performance gains?
I've heard very good things about them in older V8's. Will be good for high boost applications as you can run a larger gap.
whats the point of the larger gap, a larger spark hasnt proved to help anywhere, all it has to do is explode and weather its a big or small spark its still going to go bang.
If thats true.. then why doesnt everyone run a 0.1mm gap which would never have any trouble of igniting? Why would anyone have ever chosen to make a spark plug larger than absolute minimum? 'Its ok its all the same big spark or small spark it all goes bang' crikey... Dont have anything educated to say -> Dont say anything at all.
i dont mean it like that, i mean like running a big gap and then a bigger gap isnt going to help. i havent seen anywhere EVER where having big or so called better spark helps with anything at all in an engine.
Thats because everything you see is already running the largest gap that the system can afford. Its combustion 101.
It works exactly as advertised. It will convert a stock coilpack (if new) from an output of 21 peak kilovolts to 28 kilovolts. Thats a 33% increase in power to the spark. This will have benefit in running high boost applications, which 95% of users on here wont need. It allows more complete combustion at top end, and prevents miss firing. Unless you are planning to upgrade your turbos and run 20+ psi then I wouldnt recommend one as you wont get any additional benefit IMO. This basically does exactly the same as using the splitfire coilpacks (see other thread) although no one has actually measured them to see if these actually do what they are meant to yet.
My 5c, I have this in my zed, was in it when bought it. never had any problems with unit. power all throughout, never breaks up - Bill
Not as far as Im aware. These were brand new coil packs measured with the "snap-on" brand of ignition probe.
a better spark does help in an engine topfuel cars make over 7000hp and 6000ft/lbs and they run twin 44 amp magnetos and dual plug each cylinder! but what u will probably find iis that your ignition system will be fine untill u start trying to ignite massive amonts of mixture due to very high boost applications...
