Dont Be Fooled Into Buying Cheap Coil Packs.

[Ben C34]

dude, heaps of people make twice your power with yellow jackets. I am making 274rwkw with them. explain how that can happen if they are so shit?

[XKLABA]

I think you missed his point, he made less power on his setup with them so if you change the yellow jackets to stock and you might pick up x amount of power on your setup

[Ben C34]

oh, so a random Guy with a low power setup claims such massive differences with no dyno proof, and that means somehow I am losing heaps off power to a non existant coil issue?

cool -__-

Whoa guy - why so defensive? If you haven't tried the coilpacks back to back yourself, why are you so strongly convinced there is no difference?

[Ben C34]

Sorry that came across a bit harsh. Fair point, but when a combo makes the expected power, and comparable to others, I dont believe im losing out on any power. The people that pick up power are doing so because their old coils werent working properly. Actually losing lower by changing coils (unless the new coils are faulty) hasnt been proven. There are back to back tests that show there is no power to be had by replacing functioning coils with another brand.

im not willing to do my own back to back test, but I will have a set of yellow jackets available soon, as I am going to use ls1 coils I got for nothing. If anyone wants them, they can have them so long as they do a back to back test when installing them.

Thought I'd save some coin by buying the JJR (red) coil packs...

15 months later = FAIL (stock turbo@10psi)

BTW - My tuner said that the popping/misfiring under boost caused by these POS coil packs could be as damaging to the engine as knock!

Replaced with Splitfires...

15 months later = SWEET (3076@19psi) never missed a beat

Not only did I not save money by going cheap... it actually cost me and extra $400!

he didn't say these coils won't make power, he said on HIS setup he made less power with the yellow coils then he did with the stock ones and how do you know 1) he didn't make less power, and 2) your setup won't make more power by putting stock coils on your car, you've said our not will to try it but are willing to take a shot at someone that has

why so angry, he is just telling us what he has experienced with his car, what does his power setup have anything it do with this issue if anything the fact his setup is so low power showing that kind of difference would mean it would be worse on a mild setup like yours and even more so on bigger setups

can you prove he didn't and if your not willing to test them how do you know you don't have an existing coil issue or won't make more power by changing them and if you don't have an issue and these coils can make the power why are you changing them ? cause, and please correct me if I'm wrong, free or not the LS1 coils are not a plug and play setup and remove the factory look giving a greater chance of a defect if pulled over

i made 360 rwkw on a neo rb25 with yellowjackets and plugs gapped at 0.8mm running e85.

have heard of others not having such luck with them. same goes for splitfires.. success stories and dramas everywhere.

my motor now runs MSD blaster coils... the spark these babies throw off is nothing short of frightening

[copycutter]

Did you gain power going to such a strong spark?

[Simon-S14]

dont know.. as no other coils would work haha.

best part was the MSD blasters are 70 each (need 3, run wasted) plus a set of custom leads and an ignitor. strongest spark ever

[hypergear]

Thing in China is. If one business makes money by copying some thing (doesn't mean it works), then every one else follows. They will also try to produce and sell them at a cheaper price. Externally they appears identical, internally they could be very different.

Exactly the point, and to make sure the testing was fair i ran them all on a stock car with minimal mods(not even my car) I did the tests quite a few years ago simply because i was curious to see just how much difference there was from coil to coil, the only new set of coils involved in the tests were's the yellow jackets, the stockers and splitfires were old ones of previous setups of mine and had done easily 20,000km's on the split fires and the stockers around 80,000km's

Yes thats exactly it dickhead. why dont you go and pay for dyno time to test some coils and see what results come from it and tell me how much you feel like sharing your results for others to gain from?

I performed the tests over 3 years ago stock car as i thought it was the only fair way to test back to back. I hope the shitty yellow things have improved A LOT since i tested them but i cringe when ever i see them on a car. The sad part of all with the test i performed is that the car idled nicer and felt smoother with those shitty yellow things on it but once the tests had been done both myself and the owner of the car where extremely suprised and shocked.

Spark is not something you should cheap out on but if you are on a tight budget look into retro fitting LS series coils which can be had extremely cheap from the states. If you want the best there is out there.. BPP's CDI setup is the most impressive bolt on solution but comes at a cost and its not a complete bolt on plug and play.. you do need to snip and crim the 7 ignition wires into a new plug(supplied) to suit the new ignition harness.

[Ben C34]

No need for name calling...

So we could assume the coils have improved, as there are plenty of people making 250+ with yellow jackets.

At the end of the day,i don't care. the coils were on the car when I bought it, and I will be going to ls coils as they are clearly heaps better. But I seriously doubt I would make more power as there is no issue currently.

you would be surprised how much they pick up with a larger gap and decent coils....

[GTRsean]

If my mate (Sloane) goes for the splitfires and gets rid of his yellow jackets, I'll ask him to put the car on the same dyno and see if it will run more than it's current 370.8RWKW.

[sonicz]

Interestingly I definitely felt improved power output going to the yellow-jackets over the stock coils even though I had no issues with the stock coils. But then again I also indexed the new plugs I put in by facing them toward the intake ports.

Ergh if they are so cheap why did I blow ~$500 on yellowjackets If I could get these MSD blasters for that price?

Any info/links?
