Just want to get some feedback. This is not a dwell time discussion.
I know Kane has them but he hasnt really been able to drive his car much-----yet.
I dont know of any other FI car with them other than MM?
I know Juan has the MSD version.
Anyone else done this?

So far, almost every FI car I've tuned in person has had them.
Looking through my customer database (15% of which is FI), more than half of the FI people list LS2 coils as a mod.
I can list user names, but I don't want to "out" anyone that doesn't want to be "outed".

any of them made 320+ whp ?

I have both; the LS2 coils on the trailing plug, and the MSD/LS2s on the leads.
Update -
Leads are MSD Ignition 8247.
Trailings are standard LS2, not the Yukon's.
Spark plugs are set to 32.
No misfires....
Most of you are incorrect. Kane has the GM D-585 coils as that is what is used in the BHR Ignition System. So does Danny (NgoRX8) and for the same reason. MazdaManiac, as well. 497 other owners, too.
The only kit I am aware of that uses actual "LS-2" coils is the Esmeril kit.
The D-585s have, for a LONG time been referred to as "LS-2" coils but it is erroneous to do so as the LS-2 coils emit only about 40 mA of current while the D-585s emit about 120 mA (according to the guys at MegaSquirt). The popular MSD coils emit 150 mA but at a slightly lower voltage (according to MSD, themselves).
As Kane helped BHR discover in the early days of the "Dwell Time Controversy", RX-8 applications flowing more than 300 gms./sec. and using GM-based coils of any selection typically need to have the input dwell increased from the factory maximum of 3.2 mS to about 4.8-5.0 mS.
As for using LS-2, D-585, or MSD 8245/8246/8247-series coils on boosted applications, they are all electrically compatible with the RX-8 provided the proper wiring scheme is used but the above dwell changes need to be implemented when 300 gms./sec. is achieved. There is no need for the use of ANY kind of external ignition components, boxes, gizmos of any kind in these cases.

The LM7/L59/LM4/L33 5.3 L engines are, essentially, iron-block versions of the LS-2. There are a bunch of other differences to make them truck applications.
At this point, I have yet to find a coil with a higher current output.

I am talking about coils and you are talking about engines.
I discuss these coil variations nearly every day with suppliers in the industry and I am trying to clarify the nomenclature for those reading this thread because this is the language the ignition component industry uses.
I am also, one AGAIN, trying to explain to others why BHR prefers to use the "D-585" coil, as opposed to the "LS-2" coil.

bingo Ray--thanks for picking up on that. There is a slight difference between the "yukons" and the "ls2" coils oem dwell tables.
Maybe a thread needs to be started under "Ignition set ups for FI"?
Open discussion for the thoughts on coil set ups/wires used and why, capacitors used or not? Maybe someone could actually scope a twin power!
Thoughts?
I have the BHR ignition but not a verified 320+ whp. I have hit 400g/s however and could probably pull more with a boost controller with gain functionality.

I could probably contribute to a good argument on why I think the stock coils are not so bad as everyone makes out and how to get the most from them ......
