My question is at what point will a mag become necessary? I'm a newbie to blowers and such. Just to make it interesting it's EFI to boot. When I started out I had a 1071 street style blower and a -1 pump, MSD 7AL and a MSD HVAC coil. Ran a best of 6.80 @ 200. Moved up to a 1471HH blower and a Enderle 110 13 gallon pump. Boost jumped from 11 PSI to 23PSI. Still running the same ignition. I'm having a situation where the engine quits about 30' after the launch which I believe is due to a faulty fuel pump. Someone suggested the spark output may not be enough to handle the extra boost from the new blower. What is the opinion of the experts on this forum?
