Haltech Wiring up Ls1 coils to a E11 questions

I spoke to a gentleman in SEMA last year and he said he installed a single LS1 coil onto a distributed V8, ran the charge time to i think 4-5mS but i cant really remember, and ran this engine (which was on an engine dyno) to 7000 rpms, and even though he said the coil got VERY hot it did not fail, they stopped the test, let it cool off, and restarted the motor again and it still ran. So by those standards, where the coil is actually firing for 8 cylinders, you could say that is a pretty abusive test and it passed.
So, i guess they are pretty tough coils.

The only way to know the truth is to actually test it on the application it's intended for.
With that said from my experience and others on high horsepower/rpm rotary applications they did not perform as claimed.
One thing I've learnt in this buisness is that experience in not gained by reading and believing the hype or jumping on the bandwagon like most do but by actual R&D or trial and error.

well we just purchased some LS1 coils for use in our FSAE car so we are hoping they are going to be able to take at least 12k rpm. Eric over at haltech tested them for us and he said they were working fine on the bench at 16000 rpm with 6ms of dwell. so i think im going to run 6ms and we shouldnt be going over 12k. ill report back and how they did. im going to install em in the next hour or so.

well drove the car around tonight and it seems that the coils are working absolutely perfectly at 12000 rpm at 6 ms of dwell. that is the limit of the haltech currently because of the crank wheel so i probably wont go any farther then that.
