MSD Stacker - don't bother

[Jon]

About 10K miles ago I installed a MSD Stacker on my 2003 Cobra.

MSD Stacker installed



To date I have not been able to substantiate any gain in power or mpg.


I was hoping the MSD would help address the stumble my car has with tight (.035) plug gaps but there appears to be no benefit. Consequently, I did not bother to dyno test.

With older, carburetted cars the MSD ignitions worked wonders but the new C-O-P arrangement must be difficult to improve on.

Bottom line: save your money and time and pass on the Stacker.

I think that the only thing on themarket that is worthwhile at boosting spark would be the KB BAS kit.

i think the spark on these new cars is so hot even when you improve the voltage you cant tell the difference
