the OP stated that they were going to do a Dyno comparison and post the results. The results haven’t been posted so no, going back and reading doesn’t do enough for me or anyone because no facts were presented. Just wondering if the dyno session ever happened and what the results were.

Respectfully - That is dead False. EVERY TEST ever done on a Granatelli Coil and or wire has resulted in gains - Even the COPO guys are switching and seeing results on time slips

Personally, I have never seen 1600 with stock coils. To say you can make 1200hp on a stock coil does not address how much more you would have made with the Granatelli products. You can go 155 mph on VW tires but that does not make it better then a VR rates and then the ZR rating - just an example

The dyno shop had some computer problems so I could not do the test as planed . I had good luck with the coils on my TPIS LS3 NA engine that made 633 rwhp . If you need coils I would recommend them

Check it out and let me know what you think! Seems like a good idea for higher output coils
