coils and coil packs??

[GT350-R]

track numbers, let’s put the car on the track and back to back, I pass with one, swap to the other

and go back and forth 3 or 4 times

Great call Accel or Granatelli or MSD. Hell call them all. I am sure they would jump at the chance to sponsor the worlds fastest Vortech S550. Shit Granatelli owned Paxton and Vortech at one point call your pals at Vortech and get them to squeeze Granatelli for a free set.;)

And lastly like I said I am not racing anymore - I merely told you what I have experienced. I know what the end result should be. A modest gain. Again I am sure a company like GMS or the others would support established racers. Oh Wait...they did that already...Every class winner in Coyote Stock for the last 3 years

You are so misinformed.:lol: Ive ran e85 in my daily for the past 4 years. An easy 60k. No issues. People that have issues are doing it wrong.

OK, I don't know how I am misinformed. Several members of this forum have talked about hot starting problems on e85. That means its not so easy to do it right I guess. You can debate about reliability because you haven't had a problem in 4yrs/60k but nothing else I said is even debatable. The funny part is that I even said despite the potential downsides I would still run it if it were available in my area.:frusty:

Sorry to the OP, didn't mean to take this on a e85 tangent. Back to coils and they're useless or usefulness.

The bottom line is the 11+ coyote coils have been in the 7's

This is all you need to know. Save your $ as Beef suggested.

no you were wrong about more i just didnt touch on it. Poor starting is tune based. Mine starts easily, hot or cold. Ive had a drop in mpg, but i still get about 25mpg avg. Just reading about memebers here having issue doesnt make you well informed. My city has it all over the place, i suppose im lucky.

As for hard stance my friend Why are some taking a hard stance the opposite direction when they admit they have NO DATA to support their claims

No data? Really? The stock OEM 11+ coyote coils have performed into the 7's, and a bunch of cars in the 8's...how much more data would you need? Proven performance many times over.

Additionally, did you miss the post in this thread where someone witnessed a back to back dyno GMS coil swap on a car making 600rwhp and the car picked up 1rwhp? Is that well worth the $500-600 investment?

And for the record your claimed .07 improvement could easily be attributed to track and/or weather conditions.

Anyway, I think enough information and opinions have been documented in this thread for people to make an educated decision if aftermarket coils are a worth while addition to their coyote engine.

A lot of you are aggressive idiots that would rather create controversy then think before your speak (in this case type):eyebulge: The fastest this and the fastest that’s You're missing the point. Take anyone of the so-called 11+ and run a back to back test at the track. then come back with proven or disproven results. What we do know is I made more power. I saw it and felt it. SOTP and at the track back to back. Mileage was better as well - not that I gave a crap about mileage 80% of the time when I drive it I’m on the chip anyway.

Some asked and I answered. My coyote vert with Vortech was faster with GMS coils, my 4v 98 was faster with GMS bricks and Vortech as well. My point was and still is Don’t be so quick to trash any product you have no product knowledge about.

I missed the post where 1 person said they only saw 1hp gain with GMS coils. Did you miss the 3 videos posted by AM and GMS on three different coyotes on three different days that all saw roughly 10 to 12hp or my mph gain at the track?

DING_DONG - anyone home? Forget about the ET gain on my vert and look at the mph gain as well - as for conditions. Same track same day and it repeated every time. I'm not the only one. I merely use personal experience to bolster validity.

Truthfully i don't care if anyone buys better coils - i don't gain a buck and it gives the guys that do an advantage.:first:

 

[GT350-R]

Last back to back Dyno with stock then GMS coils I saw, the car gained zero. There was 1 hp difference on a 600 whp car. Was all i needed to see.

Frankly, salesman here still hasn't provided the back to back same car comparison either time or Dyno to prove anything. Just a lot of hot air and I have them cause I believe they work. Which is no better than what he is accusing beef of

Not really = i did explain repeatedly the gains I saw on the dyno and gains I witnessed at the track.

Whatever...like I said there is enough info in this thread for people to make an educated decision. For me, my opinion is any aftermarket coyote coils can stay on the parts shelf (right next to the throttle body spacers).

I see you got your panties in a bunch and referred to some people in this thread as "aggressive idiots"...sorry, to that I will not respond...I can not stoop to your level and resort to insulting people out of frustration, just not my style.

I will tell you that you have really made a great first impression on this site! Congrats!

189 post from you and you're hanging with me:headbonk: I did not call anyone specific an idiot. Just a general statement that continuing to write full throttle aggressive get no one farther down the road. I agree I can fire back and I am a keyboard cowboy sometimes but I did not come out swinging. I answered this person questions with specificity and personal experience

We can agree TB spacers do nothing. The spacers came into notoriety back when manifolds where aluminum and heat soak was darn near immediate - TB spacer makers are still riding that wave:(

I can see this is a very drag race conversation, but for guys who don't drag race but road course and need every little ounce of power and cant run a supercharger. It would be interesting if these would have any real power available or snake oil? I'm in need of about 50 HP for next year to be alittle more competitive and these are on my list of products to possible reach this goal.

snake oil

Sorry to bring up an old topic but I am interested if anyone has any more experience with the GMS coils. My friend with a 1LE Camaro bought a set and we did 3 passes before changing them and then 3 after. He matched his previous numbers averaging 435whp before the coil swap, then after the coil swap he averaged 440whp. A solid 5-6whp gain across the entire rpm band. Thats not a lot of power for $500 but I don't know if we may see more or less power from upgraded coils on our engine. If your looking for every last NA hp because you are determined to stay that way then its an option. Granatelli has a dyno session showing like 16whp gain on a stock PP but I am not going to assume that would be typical. Before anyone starts flaming, I know that we do not NEED the coils as the stockers are reliable and capable, but if more complete combustion improves power and mileage, some of us might be interested who are staying NA. I may give them a try and report back but I would love to know if anyone else has any first hand knowledge since this thread went silent.

Here is the dyno comparison of his results for any interested. Remember these results were repeated, not just a fluke. We made 3 passes each, the dyno sheet is representative of the average results compared.

Interested in your results... I have built many cars and a hotter spark was always on my list of things to do.....this thread has to much back and forth to really determine what works..

Still waiting on my buddies dyno to be up and running again. His computer crashed while I was on the dyno before we had a chance to swap the coils. He got a new computer but the rpm pick up broke and he is now waiting on a new one. I will report back as soon as I get a chance to get back on the same dyno.
