Mind blown, his technical ability and precision is taking over RUclips. In sure the little kids don't dig it, but coming with hard core facts and accuracy is what the people want.
This is how you get credibility - thorough in house testing AND showing results of said testing. I bought a platinum racing coil kit for my RB26 last year and I've recommended it to others. Particularly like the custom O ringed stalks, so it fits nicely under the stock cover and prevents gunk getting down there.
Changing the coils shouldn't net any power gains on their own, unless you were suffering from misfires beforehand. It will however let you make more power, or run a larger plug gap. They will also probably be more reliable as you dont have to push them as hard to get them to spark and you know exactly how close you are to their limit if PRP provides you with a dwell details.
@@tx5brent As all internal combustion engines do, even if you don't hear the engine misfire. If you can increase the burn efficiency on the power stroke, do you think it would result in better power?
@@tx5brent You can get increased power from a better spark, even if you werent misfiring before. Better burn can increase power. May not always do it, but can.
This test remains the gold standard. Would love to see a test between the various different R8 coils on the market. Specifically the Denso, NGK and Bosch. non of which appears to have been the coil used in this test.
So glad you looked at this with cost in mind. Yes r35 coils are the best but are very expensive. 90% of builds do need them at most people are only sub 500hp..
Can confirm the same findings, new R8 genuine coils are 25eur each, you can buy from anywhere, can't beat the performance to price :) Another nice thing they have over-dwell protection build-in that will NOT initiate a spark at the wrong time and destroy your engine like the LS "smart" coils
Anything between 2-5ms will work reliably fine to 10k rpm 4cyl 4 stroke engine. Generally is a straight swap without the need to change the factory dwell table. Here is the table i made and use for aftermarket ecus: imgur.com/aqxHYiQ
You mean LS "crazy" coils.. Seen two engines go boom because the coils started to fail.. One car blew its entire muffler system off due to a severe misfire and broke the oil pump shaft due to kickback. :(
Fun fact: Those R35 coils can also be found from 1.6 DIG-T engines. For European guys it's great news, as you can find those coils from Renault too, sourcing those coils shouldn't be too hard..
They look like the same as the coils on a lot of late model nissans, same module just slightly different moulding and stalk. Good news if you can get decent coils from any wreckers for next to nothing.
ABSOLUTELY GORGEOUS video to watch!!! Thanks for all the work you guys provide! On a side note, guys, would you do a CRANKSHAFT comparison video of RB25/26/30 vs 1/2JZ???? It would be very interesting to see the material and all the journal dimensions!?
9:30 Also check your R8 coils if are genuine, these could be from the dealership, but generally they will be laser marked. Better to try one from the suppliers, NGK U5014 is this case just to make sure. But from my own tests your energy measured is about right :) (need to find my old excels:p)
an overall fantastic job taking the time to go through all these coils in such a well-organised test setup, only thing which would have been nice to follow up on was at the beginning of the video there were talks about specifics such as what coil could output certain dwell ms and performance at different plug gaps etc, but all came "rushed up" in the end. id be really interested to see just what the "internet" lists as respectable dwell times for these coils compared to the real-world testbench setup, a great example would be those d595 lq9 coils apparently going trigger happy with some dwell lol
some valid points, we were surprised to discover that lq9 auto fired, but advertised dwell was in some cases no where near the actual, none the less very little data available until now :)
Had problems with the dwell on my Yaris coils on my 1JZ when it was first tuned. The car never ran right and I had to head back to the tuner to get the dwell adjusted. I also had one coil crack where the mounting bolt goes. Though they're performing fine for my needs currently, R35 coils and new brackets would be the go. The only downside as said in this video is cost. Great video anyway, thanks for going to this effort.
I'm guessing they're the same as the Yaris Denso coils. But an actual test would be nice. I'm upgrading to coil packs on a b series so I'm very interested also.
Incredible work guys. Been waiting for someone to do this testing. Didn't expect anything this comprehensive though! Would be amazing if you could release the full data sets somewhere. Would also be awesome to do a second round oincluding packs like Subaru, Honda, Mitsubishi, etc. I know it has to make monetary sense though, so hopefully this video does very well for you. :)
Those LS1 and LQ9 coils came out 20+ years ago on 300hp NA engines, why didn't you test coils from the much newer and twice as powerful LS3/9 or LT1/4 style of engines ?
Because LS coils are trash and blow up engines when they get hot. I have had crazy intermittent misfires from them and refuse to tune a car that has them. The sporadic jitter and timing issues they have aren't worth the extra spark energy especially with r35 coils that seem to work fine with regular spark plug wires. I actually am using r35 coils on my LS build engine.
haha talk about timing! Literally was looking into coil kits for my RB this morning wondering do I stick with my splitfires or go with R35 etc. Another killer video guys thanks so much
I would like you to compare the R8 coilpack to some other VAG - group coilpack, for example from 1.4-1.6 liter turbo engines, one that fits inside the standard coilpack cover in rb engine. Those coils are a popular upgrade in europe due to the availability and cheap price and it would be interesting to see if the R8 coil is actually better or if those produce the same numbers.
yep, lots of similar VWAG coils, my A4 1.8T (B6 generation) runs an identical? coil, I've heard people using them for other projects, they seem decent, but to have proof/numbers on that would be nice!
@@metalinvalidmatt yeah, and it would be nice to see if those are all the same underneath so that the R8 coil is not what is needed and a shorter one would perform the same.
@@josbanse Was just about to post almost exactly the same question regarding the shorter variation of vag coils until I scrolled down the comments! I had those 1.2-1.6 liter tsi short coils on my +700hp 1jz vvti. Now I'm trying the newest revisions of R8's, because I had strange misfire issues that was not completely sorted by doing complete engine harness rewire. It could have been ECU issue too, so I upgraded to EMU Black now.
I guess Im randomly asking but does any of you know of a method to log back into an instagram account..? I was dumb forgot my account password. I love any assistance you can give me.
@Damian Johnny i really appreciate your reply. I got to the site through google and I'm trying it out atm. I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
Wow, thanks for this! FYI: That AEM coil is a rebranded mercury Marine coil. If you have a friend in the marine outboard business, he'll likely have a bunch of these coils laying around! Lucky me...
Thanks Andrew and Herman! Really great content and as an electrical engineer I have nothing to comment on the tests, very well executed. One question: are you guys open to share the dwell settings of each coil?
Someone who actually knows about electrical systems agrees with us, yet we still get people who claim to know more from watching other youtube videos. Welcome to the internet :)
Bit of a bummer that the Subaru COP coil packs were not tested but understandable being this is options for the cars you're working on. Maybe expand on it in the future?
However you've missed one more test, which is simple enough to make. This test is valid for the clamping voltage you've used with your diode box (i'm assuming 1000V or so). You need to also test the maximum voltage a coil can produce since spark initiation in the cylinder varies depending on several factor. You can use the jig at 3:07 to do this, or better make it with 2 adjustable spheres to measure the max spark gap (1cm in dry air is about 10kV from memory if i remember well). Coils requiring spark wires will be the first ones to lose this test (usually they max around 20kV)
Depends on the actual coil used, mine's are rated up to 60KV, most dedicated coils from Toyota are at least 30KV if memory serves with 45KV not hard to find in the aftermarket.
A Few questions. Why not test a Barra fg and b series coil? (more for my own use lol) Also arent ign-1a mecury marine coils that everyone re-brands? Why is everything purple? is that a filter on your camera? Other than that your test setup looked legit people cant argue with that without showing they're better setups
@@HalferLandPerformance the ignition / Motive guys did an amazing job I don't wish to discredit anything they've done by asking them to do the k series coils .Yes I have seen the stock K series coils supply a great spark to 1000bhp+ builds
I've done similar tests. What total voltage is the zener diode string on the secondary side? Mine came to a measured 1700V. One coil you left out is ICE Ignition's LS coil. 144 mJ at 10 amps primary current.
I know but every Vw fan boy has to fit r8 coils it was quite funny especially when the car needed a 28f5 recall after the customer had bought “uprated” r8 coils
Herman Urriola , Great informative video. Very thorough as are all of your tests. But the question that everyone wants to know, Who is the Australian supplier of the R35 Coil Packs???????????
@@hermanurriola138 It would also be interesting to compare some of the old school CDI and also new multi-coil CDI coil setups that are available, if you can get your hands on them that is. Setups like the old HKS Twin Power CDI, but keep it RB specific or testing will just get way out of hand.
standard Ford Zetec wasted spark coil puts out at minimum 37kV and it is designed for double platinum plugs with 1.3mm gap. For me at least it seems that it deserves a place in this test because it is dirt cheap and extremely common and quite sure more powerful than many of the selected test subjects so please have a look at it and how it compares to the top of the currently tested ones
just curious, was that R8 coil genuine? it might be just the shot, but the top looks blank where it should have parts numbers etc, commonly seen on knock offs.

At the price point nothing beats the r8 coils they use to actually be $25 a pack now they are $30. Most these other packs are $50-$100 a pack.
I like your approach to this. No more internet fanboy hype and hearsay. These are the facts, mmkay?
This test remains the gold standard.

and the Benchmark ones as they make some big claims with very little real world data
Thanks for the video and hard work on the tests.
Good test, We run the R35's on stock coils up to around 2200whp, Above this on Methanol we swap to plug wires with dedicated coils.
beautiful thing aren't they cheers
Man the videos you guys are pushing out, fkn quality and relevance....
I did the LS1 coil swap on my 25 about 7 years ago, I've had zero issues but there's obviously better options now, as happens with everything
