I would love to be proven wrong on that. Again let me just say I am in no way bashing your product or saying it isn't worth buying. Personally I just like to see actual data, nothing against you or anyone else.

I doubt I would be buying the kit anytime soon any way. Probably best to wait til I am out of warranty.

 

Right, same boat here, lets get that on the table, I dont think anyone is making negative comments toward this product. Just looking for more data to further reinforce the purchase decision thats all

 

Overall, it could be the Mazda changes, Premix, weather conditions, Ethanol Content, or one or a combination of variables that cause your S1 or S2 to last longer, The real question is... why the hell wouldn't you invest in something that is preventative in the deterioration of your 25k+ automobile. Thats like saying I'm not gonna pay for car insurance cause I don't believe I will have an accident... Its just dumb.

BHR Coils have been proven on S1's, based on Dwell, something with electricity, and a bunch of other stuff I wont pretend to understand, so unless there is a whole new engine in here that I wasn't aware of, It should benefit the S2, possibly not as much as S1, possibly more, but benefits are longevity based. Why wait 50k miles to realize "I should have bought BHR coils 60k miles ago"

So I state this, do not question, or ask for proof that the BHR coils are worth it on an S2. PROVE TO ME that the S2 Coils are better than the BHR coils.

I leave you with one of the wisest phrases I have ever heard: An ounce of prevention is worth a pound of cure.

 

I 100% agree with you on many aspects of your statement. I think we have two sides of the spectrum going on in this thread...

one side says "The s2 coils are better than s1 coils" without any actual data proof

other side says "BHR coils are better than s2 coils" without any actual data proof

But rest assure that no one here is saying that s2 coils are better than bhr coils.

 

No Problemo cbmmm3,
I have a 2009 Sport
Located in Northern Cali
Approx. 5k miles when installed BHR Kit
Plugs didnt need changing
Only have Revi and Ram---only mod ***hopefully not for long
I actually install the kit right in the middle of a 3 week heat wave. The temp was approx. 85+deg. daily. I also Tracked the car the weekend after installing it on a 105+ deg. track day....sooo if something was gonna happen it couldve very well been then lol Before I changed to BHR I took my 8 thru some local hilly snaking back trials, so I can tell between before and after BHR kit. I was just surprise how much of an defference there was, because of how New my car was and still had a noticable change.

 

Believe what?, when your original Ignition system was not even faulty...there is a massive difference comparing S1 owners who renewed defective and aged coils for the new BHR kit. I guess if they renewed with the cheaper priced OEM upgraded coils they would have noticed a 'difference' also.

So what was the 'noticeable change' from what to what...Mileage, performance, speed...or my $400 must have made a difference.

 

If had brand new oem coils and a used set of BHR coils with 20k on them you still would notice a big difference. The oem coils commonly fail before 30k, so during the life of your car would would have to replace your coils atleast twice maybe more. Four coils @ $45 replaced twice = $360. In the long run the BHR coils would be more reliable, cheaper, and offer room for a few more hp. Ash8 what is your problem with the BHR kit? The price?

 

I think his problem is the same as the problem I am seeing. If you go out and spend $400 on something you will feel a change. Like people who go out and buy a new exhaust and say they can feel the power it gave them, when feeling 0-3hp is just not gonna happen. In their minds there is a noticeable difference.

On another forum I post at theres even people arguing about using chevron vs shell vs bp or whatever stations you have around you, each swearing up and down they feel more power with their brand of gas.

I plan on trying the bhr ignition kit eventually, but not until I am out of warranty or my current stuff stops functioning.

 

Jeez, I DON'T have a "problem" with the BHR kit.

For the 100000000th time Series 2 RX-8 have a "modified" coil from the factory, plus 2 other related modified components 'said' to fix the early expiry life of the S1 Coils.

My point is in just OVER 2 years we have not seen ANY Series 2 Coil Failures.....YET...TIME WILL TELL...

Some, will say they know the "upgraded coils" have not changed and will do the same as Series 1, AGAIN they are guessing, and AGAIN I say time will tell.

But hey, I do get the American love affair in throwing out perfectly good parts just to put quotes in their 'sigs'...IMO more money than cents...but I was like that until I learned a little more...Blah..Blah...Blah.

 

Ash,
While I do agree with you that changing parts when it is not needed is useless what do you think about the output differences between the stock coils and the ones that BHR uses?

In my opinion the stock coils have 2 problems: 1) the expected life 2) the current output
It is more than possible that Mazda addressed only the short life problem, the only one that really matters from a market point of view.

I'm saying this because i changed my stock coils when they were fairly new (12000miles) so with still, at least, 30.000miles of life ahead of them. I have experienced more than just "empirical". Fuel consumption and spark plug life both got better. Performance wise it was just some g\secs more.

G

 

Anyone have access to a nice oscilloscope? Lets get some graphs on the S2 coil packs just for f**ks sake. This back and forth stuff is getting stupid and we aren't going to get anywhere without some actual data.

It would be nice to get some nice graphs of current ramps on the S2 coil packs as well as the voltage spikes and settle between sparks.

 

****, do you read what I wrote..

G you changed YOUR Series 1 (S1) Coils.. correct???

The SERIES 2 Coils have been changed, along with base plate, and leads.

Time will tell....BUT yes, they don't like the heat...

 

Agree, and my post was not to you...

END OF SUBJECT!

 

^^ Lol, no worries, I understand where you are coming from. I think people are thinking we are bashing on BHR coils or something, but speaking for myself, I like to know what is in my car and what I put in my car. In the end I could end up getting a BHR ignition pack and thats fine by me, but at least I am doing it based on data and based on the knowledge that I earned on that is currently in my car vs what someone tells me is better.

Its not anything against anyone, being an engineer i just like data so that when someone says "why did you do that, that was stupid" i can turn around and say "actually .. here is data proving otherwise"

 

S1 and S2 use the same ignition coils

 

Yes, I changed my fairly new s1 coils. However did you read my premise? Wouldn't it be possible that, if all they addressed was the heat problem, you could see some benefits even on s2 cars? An oscilloscope could tell!

 

^^ 10000x agree ... just need to find someone with a nice digital scope. If I was still doing thesis work I could have snagged one for the day but unfortunately I had to be stupid and complete my thesis lol .

 

I'd buy these today if I knew how to work a wrench.
I'd like a little bit of ooomph in my R3.

 

Aww your going to leave me hanging like that aren't you.....

 

Will I be getting these changes on the coils I ordered?

 

Crossing my fingers that I will be getting the new changes too , since mine haven't shipped yet. Good thing too, I haven't had the time to install them anyway

 

Looks like we both got R3's too...let's hope we get this new change, but also give a good pre/post results. I'll see what I can do.

How many miles do you have on yours? And are you replacing your spark plugs too?

 

I've got 30,000mi on her. I ordered the works as a heavy 30k service, since I bought the car @ 24k and don't know the history. I did get a bone stock dyno last week as a baseline.

My current plugs are healthy but would not be wrong in replacing them now. I'm not noticing anything specifically alarming about how she's running. I've been trying to pay attention to the subtleties of how she's behaving, hope to give some good info on the kit.

 

Just opened the box and I'm already impressed.
Instructions were clear except for VFAD. I'll do a little research and don't expect any issues.

Also I should be able to put in back on the dyno b4 Christmas (understanding not significant change but still curious).

Will report back tomorrow.

 

^^ by any chance are these the coils with the "changes" ?
