index.php?act=findpost&pid=12397PVL's will whack out a dyno as well, it doesnt seem to be quite as bad, not every one of them will, but most. No I dont buy into it Dave, My thought is that you either have enough energy or you don't, I don't see the reason for overkill. There is an oppotunity to loose power there if the stock coil doesnt fire, but no opportunity to gain extra power just because you have a hotter spark to light the combustion. After all; you are only STARTING the flame with the spark, once the flame lights, it takes off itself, I would use a propane bbq as an example. Misfires on the dyno become very evident, showing gaps in the torque line, you can see exactly at what rpm you lost spark and where it came back. I have spent an awful lot of time on the dyno trying to exctract every last bit of hp and torque, and have never seen any improvement in either with a hotter spark..... unless the stocker was failing to light it already. Trust me, if I had seen an improvement I would have em on my bikes, but I don't. If you show up to the dyno with either a pvl or a nology coil, be prepared for it take more time (and more money).
I dynoed my bike a few times with a pvl a few years back..... I cant remember having any problems but the one time we had to block it some how. I cant remember why or even how we did it. To long ago.lol
