I like to hear what type/brands/heat range Spark plugs you guys are running and have had success with, on an E85 Iron headed (champion) 109 block with 24+ lbs. of boost.
also
How many of you guys are running the TR6 ignition setup? How do you like it and is it worth the $$$.

These question are addressed to the guys that have had experience with the above parts with a low to high 10 sec. E85 - Iron head & 109 block setup.

TIA, Mario R...
 
TR6 works great , love the rev limiter & 2 step . I use NGK6FS aka NGK 4323 non projected tip . Cheap at A-Zone or Advance auto about $2.50 / plug. Car Info in my signature .

Love, love, love my TR6. Reliable with great features. Worth every dime.
 
I love the idea of the 2 step on the TR6 but i wanted to know if anyone has noticed any performance gain?

I was using the AC Delco R43TS or the Autolite 23 and 24 with no issues with CAM2 or C16, the above recommended plugs seem to be within the same heat range. That being said, is it safe to say that the above plugs are a good heat range for the turbo Buick and the fuel being burned doesn't really matter?

TIA, Mario R...
 
TR6 is the best ignition system for a stock setup period. I’m runing a individual coil setup with it
 
The 2 step allows you to consistently build boost at the line , holding the engine at a preset rpm . The non projected tip plugs help to reduce the chance of detonation from the protruding electrode of a standard plug . Non projected plugs are popular with E85 users .

The thing about the TR6 is that it isn't necessarily the type of part that has a "horsepower number" next to it...meaning like, when you go to look for an intercooler, or some ported heads, you know that there are typically advertised "numbers" or how much horsepower you can expect to gain by adding those parts on your car, because they have a direct effect on the engine's ability to make power.

The TR6 is not like that, yet it does add power and benefits to the car. Think of it kinda like a PTC 9.5" converter...adding a PTC 9.5" isn't going to give you anymore horsepower or cause your engine to all of a sudden make more power, but instead what it will do, is help your engine spool up the turbo quicker than any other converter will do. If the turbo spools quicker, then the engine gets in it's power faster, which means you are making more horsepower faster than the same car with a different converter...and if you get into your power quicker than someone else, your car will accelerate harder, faster than the other car, and you will win your races. The PTC doesn't have a "horsepower number" attached to it, but it does have an effect on your car's ability to make power through how it helps with the spooling of your turbo quicker than other converters (that is just 1 of the many advantages of the PTC converter, btw)

The TR6 allows for a hotter spark, which allows for a more powerful combustion (other things affect this as well) which leads to more power. Also has a 2step that allows you launch consistently and with the car floored. More consistent launches + launching at the right rpm will allow you to spool up quicker, which gets you into power quicker.

I dunno if this all makes sense, so please let me know and I'll clarify it.

Just about any resistor plug a couple heat ranges cooler than stock will work just fine. Keep the gap around .025”. There’s no need to try and Re-invent the wheel when it comes to spark plugs and gaps.

Hotter spark does not increase combustion efficiency. I’ve directly changed dwell 1.5ms on some powerful ignition strategies back to back for a net gain of zero. Once the kernel is there the combustion efficiency is relative to the air/fuel and engine design. If your ignition was able to fire a mixture with no problem then adding more spark will not make it better.

I hear ya, but I don't think I said combustion chamber efficiency.

I said it makes a more powerful spark. I made sure to choose my words carefully there.
 
The NGK2817 is a non resistor plug which has given many , including myself , ECM problems .

Thanks guys. I expected and knew there would be many opinions on the different types of spark plugs and i'm glad I received a good response.
I've been to busy doing the dad thing, spending my time and money on sports travel, now it's catch up time. I've been in the game for a long time but have no experience with E85 or even most of the newer technology for the TB's (including the TR6). In the last 10 years i've probably only put about 200 miles on my 87 GN that i've owned for 27+ years. I'm finally working on the car trying to bring it up to date and trying to pick TB members brain for there opinions and trial and errors. I know the TR6 is a nice chunk of change at approximately $600+ with wires so of course I had to ask and have not received one negative feedback. I was in the market for a 2 step and with my aging original module/coil set up i easily convinced myself too take the plung and ordered the complete TR6 kit from Bob Bailey.

Love, love, love my TR6. Reliable with great features. Worth every dime.
 
Everything car is different but...

Id def only go one heat range cooler than stock for a street car.

You can call me a 1970's hot rodder but
Autolite copper plug work great.

Just make sure you use a Copper plug! Cheap and they work great!
