Well we dynoed a H/C stalled auto car with truck coils and did multi pulls so we whould not have any fluke pulls and the results speak for them self. The plugs were gaped at .050 ngktr55 if the trck coils were beter they whould deff show on the .050 gap

TRUCK COILS 374.41
STOCK COILS 375.20

I'm a little lost to what the results were...

374hp vs 375hp with the truck coils, i dont know about the torque tho

0.79rwhp aka slight dyno variance from humidity change? haha

Dont ruin this for everyone!!! Im waiting to see "Truck coil swap" in peoples sigs...

LOL I was sold on this that's why I tested it

So these were the D585 coils with the heat sink?

I don't doubt your results but I am still on the fence about this. Why would sponors, who don't sell these, post up inflated #'s?

Hmm, and now it gets interesting...

cars that gain could have a weak coils. swap them with another set and i pet it will show the same gain

Coils don't get "weak"..either they're good or they're not... This is one test result vs. how many??? How many times have we seen guys go from an LS6 mani to Fast 90 and posted a loss and other's have picked up 14+/- hp&tq.

IMHO..the numbers listed are pretty low for a H/C stalled auto car anyway...may have other problems

i never knew truck coils would really show improvement on a low HP car like this anyways? i always hear they were only beneficial in the high HP applications.

Would also like to know. Doing research on COP for 1000rwhp

Please tell me you kidding!

this seems like an accurate result-i really can't see changing coils adding power unless there is another ignition problem.If the coil is lighting the plug and firing the cylinder there is no more power to be had through ignition.

I dont think he is kidding at all. Im the one that started the last thread showing a gain from swapping coils.

Please tell me what I have to gain by that? Do you think I have a shed full of used coils Im trying to sell?

I simply posted the results we saw from one test. Thats all. Do with it what you will.

The numbers don't lie guys... Some people have no idea about stalled autos and dynos

Lock the converter

FWIW, Jeff @ Spectacle was merely posting some results he found in his shop. There's nothing to gain from posting HP gains from a truck coil, unless you're a GM parts dealer. So there's absolutely no reason to make direct or indirect comments about anyone making false claims, or claims for personal gain. They simply posted feedback on it.

Carry on.

PS- For the record, I've never thought it was worth the swap either.

FWIW, we tested my car back to back getting it ready for the last rental... In hopes of making the most possible power, I ended up gaining like 10 average hp under 5,000 rpm, but lost over 5,000 rpm by ~10 hp I think... So, back to stock coils for me, as my car really never see's sub 5,000 rpm at the track.... We did the baseline, swap to trucks, then swap back and the only time it lost was with the trucks. We did 6 pulls.
