What you have said is the opposite of what I have experienced. Can't tell the difference at idle/off boost but can certainly tell the difference on boost when the voltage is increased.

If you can get 18v out of the boost to the pump the 460 will move some serious fuel. Link to comment Share on other sites More sharing options...
BeerTurbo Donating Members 241 Member For: 6y 6m 16d Posted 16/01/20 11:51 AM Share Posted 16/01/20 11:51 AM wouldn't boosting the voltage to the coils be the same as forcing more dwell time? Link to comment Share on other sites More sharing options...

BeerTurbo Donating Members 241 Member For: 6y 6m 16d Posted 20/01/20 02:25 AM Share Posted 20/01/20 02:25 AM as it would be near impossible to find this information on barra coils as I think no one really wants to do the testing..I found some data on the Ign1 coils that come with decent test data. its just interesting to see the correlation.
