HOT start problems 401

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   so im going to post what I have done and how I end up fixing the issue.

Things I have and have done.

For the first thing it has shorty headers and man it gets hot under that hood,the 401 is sitting in my jeep yj and I never really had starting issues till I threw the headers I THINK let me explain.
previously the jeep had charging issues so I am not 100% sure about the when I started noticing my starter was giving me a hard time BUT IM HERE NOW

SO I put in a powermaster mini starter and all charging issues have been fixed im running 0 gauge wire to everything,alt starter and battery,three ground wires all 0 gauge.

jeep starts great when its cold,take it down to get gas or a coffee and it acts like its a low battery,turns very slow but turns,get home check charging system and battery NO PROBLEMS THERE 14.2V

Well headers are off the jeep and wrapped,waiting on new gaskets from summit...I dont put cheap felpro dung on my rig they suck and leak.

im looking at a starter blanket to 40bucks what could it hurt at this point.

also you can clock the powermaster a tad but you are still dam close to the header.

WELL for any of you guys that have fixed your heat soak problem chime in or if you are reading this because you have this problem..then stay tuned this will get fixed and ill post what I did CHEERS BROTHER!

	Making more power = making more heat. (by burning more fuel)

	Intake heat crossover is part of the problem. I started blocking them in the 1970s and installing a manual choke. Block them on both sides. An air gap manifold is a sure cure. I NEVER heard of a person with an air gap having hot starting issues Heat is the issue. A hot starter is not helping. I believe a hot intake and high compression is the primary culprit. Starters should be shielded if you got room. Superheated intake charge causes pre ignition and it fights the starter. Overly tight piston to bore clearance can also aggravate this issue. But I doubt it.

	There are a couple of drag racers near me that have installed units like this to start the engine: https://www.holley.com/products/ignition/rpm_and_timing_controls/timing_controls/parts/8680 And do test/tune for the day conditions for best performance. Just an option.
