I have about 100 hours on D585 coils and have had no problems with them so far. The temperature in their airblasted enclosure is usually less than 100 degrees in flight and has gotten up to 120 degrees during taxi.

I have a set of the D585 coils but have only evaluated them on the bench for compatibility with the EC2/3 (they are).

I do know that the previous version of the truck coils (D581) are not as reliable as the D580 (Corvette) coils.

Happy New Year Group,

A little info regarding the various GM ignition coils that many of us use on our

Rotary engines with Tracy's EC2 and EC3 boxes that I thought might be of interest

to those that have not seen it before.............Tracy would like your comments on the

the apparently big performance difference between the LS1 verses the LS2 Truck

coils and if an upgrade would be worth the $$ especially for those of us that have

or plan on Turbocharging in light of the higher combustion chamber pressures.......
