Mega Coilpack Test and Comparison R35, LS1, LQ9, Audi R8 and more - Platinum Tech

[@themrjones]

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.

[@dady_chill4832]

Idk about taking over RUclips and people being mad

[@russellhocken2477]

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.

[@caribbeangtr8077]

Did you get to do a dyno test before and after?

[@tx5brent]

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.

[@caribbeangtr8077]

@@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?

[@MotiveVideo]

@@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.

[@fascistpedant758]

Caribbean GTR Beyond proper ignition from a sufficient spark, combustion efficiency and power output have nothing to do with spark energy.

[@11onejay]

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.

[@manitoublack]

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.

[@rawbennett]

and the Benchmark ones as they make some big claims with very little real world data

[@andersjjensen]

I like your approach to this. No more internet fanboy hype and hearsay. These are the facts, mmkay?

[@corlaine]

Thanks for the video and hard work on the tests.

[@kevinhayward4094]

Would be great if you could compare the VW TFSI black coil (07K....) to the R8 (06E...) coil. It's a hot topic in VW circles. Everyone thinks the black ones are the same output as the R8 ones, but after seeing this, I'm not so sure now. Great work!

[@gjkrisa]

I would also like to see Ford and msd coil pack

[@matthiaskorn7544]

No, TSI (NGK U5002) and R8 Coil is not interchangeable. But TSI is not bad ( less power than R8), i am using him in R34 RB Neo. Reason: Old coilpack is break down and TSI is good and cheap replacing for him.

[@danverrall5848]

The 07L eldor is the latest revision of the same coil I'm running them in my gtr I would like to see a test done on them as I was advised highest spark output overall in the Audi/ vw vag coils

[@liftedcj7on44s]

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.

[@hermanurriola138]

beautiful thing aren't they cheers

[@Andrew260RS]

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..

[@sircefiro]

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

[@BUZDRIFT]

Man the videos you guys are pushing out, fkn quality and relevance....

[@St0RM33]

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

[@konto1ification]

What dwell time is recommended for the R8 coils anyway?

[@St0RM33]

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

[@robssm2]

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. :(

Really interesting test. Could you also test stock OEM 2JZ coil and other VAG coils as well?

[@tayzpaid4471]

I second that

[@yukbumer0]

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

[@hermanurriola138]

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 :)

[@Sir.VicsMasher]

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 ?

[@Huda88754]

Makes there coils look better that's why

[@mddunlap03]

Because they are still the same. They are a good coil just not the basest boy on the street.

[@josbanse]

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.

[@metalinvalidmatt]

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!

[@josbanse]

@@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.

[@Marko-JZX100]

@@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.

[@minivanin]

FWIW i have a Yaris as my daily (love this car) and it usually runs around 13.8 volts

[@jrbuch]

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.

[@griplimit]

It would have been nice if you could have also tested factory SR20 coils so we could see the difference between it and the SR20 splitfire.

[@St0RM33]

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)

[@ChroniclesofKToyoda]

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.
