RIPP Coil Packs

[Challenger85]

Hey everyone,

I searched but didn’t see any forum posts. Anyone tried these yet?

https://rippmods.myshopify.com/coll...performance-coil-packs?variant=33245330276434

All the reviews are positive but I’m always skeptical of snake oil products with reviews by bought customers or customers who swear they’re now a Lamborghini for $200.

Thats disappointing, thanks!

Beat me to it. Was going to post the exact same video.

Unless you go up at least 2 points on compression (10 to 1 to 12 to 1) OR go up on intake manifold pressure (turbo or super charger) you don't need Super Volt Coil's. OEM is the best for stock engines.

Good to know, thanks.

Tons of high HP motors on OEM coil packs.

I cant think of a worse thing to do than put Ripp products on your jeep.

Going back to old-school ignition systems - this applies - but this is how I explain it to those thinking a 100,000 volt coil on their Chevy 350 will make it have more power -
A coil only builds voltage until it's high enough to bridge the gap, then voltage stops building and the spark occurs. You could put a teravolt coil in place and it won't matter - if it takes 30,000 volts to fire that plug, that teravolt coil will stop building and the plug fires at 30,000.
You can have more ENERGY as far as a longer spark duration but unless the engine has physical issues, fuel issues, is weak, whatever, a hotter coil won't help.
The guy that says "but my car starts so much better now" REALLY should be fixing the issues that caused the hard starting, not putting on a bazillion volt coil to compensate for fuel system issues or low compression or bad valves or whatever.
GM introduced the HEI system to meet emissions standards for the 50,000 miles rule. They had to ensure it fired worn plugs, lean mixtures and so on.

Maybe that doesn't apply so well on these engines, but it sure did back then.

you dont even need them then.

the oem coil is sufficiently powerful enough to ignite a supercharged 3.6 on e85.

And i wouldnt even consider it until some company other than Ripp is selling them.

Especially GM LSx and LTx; plenty of 1000rwhp builds on stock coils

Snake oil.

Thought it would be interesting to dyno them since they claim 10-20 hp increase.

That's one of the best things about competition. If any of these products did what they claim, they would be OEM. The pentastar is, for all intents and purposes, the pinnacle of ICE propulsion. It might be one of the last true engines ever made for widespread automotive application. Jeep got as much power as it can reliably make.

It would be nice if someone would offer a plug and play light pressure forced induction system.

I'm talking about 60 hp at peak but an extra 60 ft lbs of torque from 2000 to lets say 4500 rpm. After that its fine if boost trails off.

I think this could address the need to flog the pentastar to 5000 rpm to get any acceleration out of the Gladiator. But then again, modern engines can run continuously at 5000 rpm for weeks at a time. So flogging the engine just upsets our sensibilities. It doesn't actually hurt the engine.

Back to coil packs - if it actually made a difference the OEM would upgrade what they use. It would be an easy fuel economy and power boost.

Back in the bad old days we had distributor caps. Voltages were in the 15,000 range because any more than that and you could get arcing in the distributor.

Then came electronic ignition and voltage went up to the 30,000 range. That was limited by the insulation on the plug wires. If you've ever opened up a car hood at night and seen sparks coming out fo the plug wires all over the place, then you will understand where I'm going with they.

Then coil packs were developed. Also called "coil on plug ignition". Now these limitations dont' exist and voltage is in the 60,000 range.

This allows manufacturers to use much larger plug gaps. (which is what really determines the voltage the coil runs at. The coil ramps up voltage until the spark jumps. If you have a .025 gap, that may happen at 15,000 volts. If you have a .050 it may jump at 70,000 volts. Either way, the key thing to remember is that the plug gap determines the voltage that the coil operates at)

Larger gaps mean larger sparks. Which means a larger area for the flame front to begin. Which means more predictable ignition, which means you can run more spark advance without knocking, which increases the thermal efficiency of the engine, which means more power and better fuel economy.

But you reach a point where combustion is so nearly complete that there isn't much left to give.

Also, modern engines with catalytic converters require a certain amount of fuel in the exhaust to light off.

Any comments that the ripp coils are cheaper than oem. I can't find oen cheaper than about 70 each.... Ripp are about 50 each. So why not use ripp???
