Did anyone end up making their own R8 coil harness ?

[twinturbos]

The reason I'm asking is because I believe I will have to upgrade my coilpack setup soon and I have a few questions. I have been trying to make the cleanest looking setup and at the same time something that can stand the heat from my top mount:

So rather than running the stock harness and the R8 adapter harness I'd rather make my own and eliminate as much as possible of the useless stock wires.
My question is:
Can I run the R8 coilpacks only off the signal from the dme and power from these 2 points or do I still need the stock power and ground on top of these ?

There's a thread on bummerboost that died off.

I personally lost interest, and have been waiting for my new VC to try r35 coils, which can be wired the way your asking about.

Not sure if you saw this already but hope it helps

I love that!

I would de-pin the oem harness, but this is the next weekend endeavor for-sure

The guy’s very knowledgeable imo

Thanks, I'll be looking into it. I already got the BL harness but I hate having 2 harnesses around for no good reason. I will be looking into it to clean up all the wiring soon.

Note some of the commentary about the voltage step-down. Reliability of the circuit matters. Mickey Mouse wiring is also a factor. Cool that he went after this though - good video and very good explanations. But IMHO DIYing this to a solution I'd want on my car would require much more.

p.s. Don't forget to cut the rubber nubs at the bottom of the coil (he didn't do that). They interfere with the coil sliding all the way down in the N54 shaft ;-).

Dudes circuit would work fine although I'd want a little more isolation from noise and feedback in case you get flyback voltage for a long term solution. I still think bypassing the internal ignitor in the dme is the best way to convert to smart coils, then you don't need to worry about any of this.

Why do people jump through all these hoops? Either go with a dumb coil like the PR, or just run a Delphi coil. S55's makes 1100WHP on the stock coils no issues, of those two we prefer the PR's. Those mercury coils are robust, and will last forever. We did some testing last weekend, and swapped around plugs, and coils at around 900WHP. No real changes or misfire issues on either option. We did end up mushrooming the Delphi coil tips from heat, and they don't like to stay on the plug very well. We made a cover to hold them down and that fixed the issue. We plan to continue to run PR coils until the switch to the adaptronic for spark which may not be for a while. We actually gave boost control back to the factory DME and the boost control is much more stable now. The car makes 600+WHP on 12-13psi. 800WHP around 22-23 psi. 900WHP around 30 psi 65% wgdc. We also had some big breakthroughs on getting consistent fueling without completely doing away with the DI which we were considering as we're done spending money on those garbage injectors. Should have some new results soon to post soon.

Kind of sad to hear that...only because I would love to see more progress on PI only control for these cars as it would do nothing but increase the capability of dual injection in the long run.

I thought the video was pretty cool so hats off to whoever made it.

Peronsally not had any issue with the factory coils though on cars up to 800whp. I saw some marketing that moving coils would help the ECU live longer, that looks like bunk to me too.

Terry, I need to talk to you about a tune for my car. What's the best way to contact you?

You might be pleasantly surprised by what we are doing if that is what you are looking for, but odds are Tony won't want to break it down too much as he loves to keep things he is working on in the lab close to the hip.

I’d love to hear/read about it. Anything that pushes this platform forward is huge imo. I mean, we’re still behind 90’s Hondas in a lot of ways, granted they had a decade head start.

I mean to be fair there are a lot of platforms way behind Hondas. Not sure if you follow Frustrate EG but he destroyed that red GTR from Texas that was talking shit on everyone.

Also King got their S2000 in the 6’s banging gears so that’s a league of its own there.

Don’t get me wrong, I appreciate Hondas, they’re where I started long ago. A manual trans S2000 in the 6’s? Good god! I couldn’t shift fast enough, let alone do any of the rest of it in that time. That’s truly impressive.

I am allowed to share this log of an close to 850WHP pull with rail pressure dropping to sub 100psi during spool up and holding between 100-200psi for the rest of the pull. This is the fuckery he is working these days.

It's pretty incredible really. Still using the F22
