Running a stock GM HEI distributor on your engine? Then Summit Racing’s got a handy Digital GM High Energy Module that lets you add an adjustable rev limiter to it.
The rev limiter range goes from 5,000 rpm all the way up to a whopping 9,500 rpm for serious racing applications.
Even better, Summit Racing’s high energy ignition module can deliver up to 50 percent higher coil drive current than the stock one.
This unit is designed to swap right into place of any stock GM four-pin ignition module within an HEI distributor that’s equipped with a vacuum advance canister—you’ll just need to remove the stock condenser. And it’ll work with equivalent aftermarket distributors too.
So if you want to add a rev limiter to your engine, but don’t want the hassle or expense of ditching your entire GM HEI distributor, a Summit Racing Digital GM High Energy Module like this is a smart alternative.
I want one
I wonder how tight the intervals are for set spots. IE: 5500 then where is the next one 6500? 6000? 5800 every 200rpm would be nice
Is it a soft limiter or hard?
Hey Kevin, this module does a momentary hard cut when the set RPM limit is reached.
