I am in contact with Bosch Motorsport nearly every day, so i will find out which one would fit our needs and also the costs.

 

P100 is a smart coil.
Basically if it has 4 wires, chances are it won't work for us.
Although they do look like they're a nice package..

 

I'm not sure where the perception of $600 aluminum blocks comes from. The coils we use are around twice the price of the stock coils. A couple hundred bucks more for everything needed to make them a drop-in, plug-and-play solution that provides a substantial improvement in spark without requiring custom fabrication, a motor drop, wiring, and a tune tweak is money well spent.

We include the coils on all of our kits 750hp on up, and they make a measurable improvement on the dyno on a 450whp car. We've used them up to around 1300whp running a .025" plug gap on the stock ECU. On cars like Anthony's we are running the ProEFI coils as they are substantially more powerful, but they also required brackets and wiring to be used, and are on cars running standalone.

Lastly, if anyone is on the fence about cost, here's a link to the product, use coupon code EVOMS10 at checkout for 10% off. Valid through tomorrow.

 

Do you include a spec sheet to the purchaser for setting them up in a standalone or Cobb AP?

 

so do you feel the 50 mj coils you use are on par with 210 mj coils that cost the same as your setup? or even the cheaper 105 mj coils they also sell? even at 600$ for the coils your still looking at 400$ for 6 brackets and you have to reuse the factory boots.
with your coils brackets are needed just like proefi coils need brackets( which are inc.). the harness and boots from proefi are provided and they are able to be used with oem dme as well as standalone

no I'm not saying your product isn't any good but lets be realistic here.

 

The Evoms package is plug and play, without too much work. The A1 coil is more a EFI standalone backage which makes maybe sense because the engine is out of the car anyway.
And also it is not for Original DME use i still think and you dont need the amount of energy till a certain power level, 50 is enough.

So two different products I think which you can't compare directly.

 

I was thinking sort of the same thing, it is a different market of people who would buy an unknown coil that has been worked over to fit and be plug and play vs. those of us who want to look at the specs and know what we are buying.

The knowledge that goes behind the selection and setup isn't free, as well as making it plug and play. I think that's where the price premium comes in. They also probably don't want everyone just buying the same coil and duplicating the setup for less money.

 

i can only tell you what my tuner and distributor of proefi products told me . which was the lightning coils can be used with the factory dme. if he says it can be done i believe him. the same can be said for the plug and play part. nothing has to cut or soldered in order to install them. they actually make plug removal easier since they are located away from the engine.

any time i can run a hotter plug and open the gap up its a win for me. I'm down to .018 gap to cure the spark blowout. ill be getting these in the near future to help get better burn.

finally the only comparison i was referring to was the price. imo the proefi coils are far superior in every other way

 

We do not offer a spec sheet at the moment. We typically run them at the stock dwell levels, at which they put out substantially more energy than the stock coils. You can raise dwell from there as needed. Shoot me an email at sstone@evoms.com if you're looking for any specifics and I can look them up.

Absolutely no argument that the Lightning coils are more powerful than the HED coils, but to actually use them in the car there is a substantial amount of fabrication and wiring involved to mount the coils and connect the ECU and the spark plugs to them.

The HED coils are completely plug-and-play, and do their job very well up to and beyond 1000hp, even with fuels like E85 and C16. They can be installed by anyone qualified on any 996/997TT in no more time than it takes to do plugs.

When we use the ProEFI coils, we mount them on a large plate attached to custom fuel rails (part of a larger, custom, extremely high flow fuel system), extend or build new wiring harnesses to reach them, and then build short MSD wires to go to the spark plugs. It's something our R&D and fabrication guys may spend several days designing, building, and installing for a given project, and is completely par for the course on a 1200hp+ build where almost everything bolted to the motor is custom built anyways. Pretty impractical as a bolt-on upgrade, not to mention much more expensive if you're paying someone to pull the engine and build everything. But absolutely the right tool for the job for very high power levels.

 

everything in a nice package. no fab work needed.

since i experienced plug blowout at 650 rwhp you don't need 1200 hp to see the benefits of a high output coil setup. no need to pull the engine to install this kit.

 

Cudos to them for offering them in a bolt-on kit, but note that those would preclude the use of an airbox or MAF(s). Which is ok if the car is highly modified and is running MAFless with intakes on the turbos, but it would require further modifications/complications for the coil install if you were not already setup that way. Again, a great solution if you have a highly modified car, but a huge ball of wax if you're like many posters in this thread with a Stage 2/3/4 car making <650whp.

The stock coils get marginal with short useable plug lifespans over about 600whp, which is originally why we developed the HED coils. On a 650whp EVT775 car, you can get about 10k track miles out of a set of .032" gapped Denso platinum plugs with them. On the higher end, we have cars like this GT2 running around doing near 1300whp with them on the stock ECU:

 

PUH! Are they mounted at the rear bumper?
Coming from racing I have very bad experience with such long cables to the plugs.

I would prefer the way Evoms is explaining.
- cables as short as possible to the spark plug.

I will have a look into the Bosch HED way and will keep you updated.

Happy new year

they can also be mounted under the engine mount allowing full use of the oem airbag.
stroker no need to worry about longer plug leads. they have been in use for decades on american muscle as well as japanese high hp cars without issue.
i think its been addressed enough agin apologies to the o/p for the sidetracked thread

 

Can anyone give the Part number for the rubber stub from the coil to the plug? A bosch part number would be best if available.

Also, if anyone has the 'official' part number from the coils, It would be great just in case I'm mistaken in my search for another coil to replace the broken electrical connection. (or i may just place that one in a easy to reach location )

 

99660210500 boot part #. #1 cylinder would be about the easiest place to install the crack unit
