I don't think an 8+ heat range plug exists with a resistor. Heck I run 8s and 9s non-projected in my GTO and Camaro AND have a lingenfelter 2 step and they work just fine. Yes I know they say not to use them but I have been for years without issue.
I just was curious if running e85 would warrant use of a different heat range plug

I had a thread awhile back out their LNC-002. Talked with them serveral times. I think it came down to plugs and plug wires used. The 2 step did NOT play well with the Taylor hi-temp wires and TR8 plugs. It would literally shut the car off at WOT. Unplug the 2 step on back to back runs and no problem going WOT.

I don't advise running a warmer plug just because you're running E85. How much boost are you running? What compression? Methanol injection as well?
To the guy that said clean up the tune and use a non projected tip, just how would you clean up a tune that already has mid 30's low 40's ignition timing and high 14:1 AFR already? What is there to clean up on a tune that is already tuned this way?
Cleaning up a tune that is already cleaned up has nothing to do with driving a car for 10,000 plus miles a year that is going to foul out a cold non projected tip plug in 2,000-3,000 miles. It has to do with the insulation used on the plug not allowing the carbon build up to clean itself off.

It's ok, everyone on the internet is an expert.

Thanks for the compliment. Doesn't hurt my feelings.
I like to consider myself knowledgeable. I've helped many people on this site and across the country and world build some pretty powerful fast cars.
I just LOL'd. Aww thats funny. Where is the hand flying over head smiley.

Currently it's a forged 346 with 9.5:1 cr pushing about 15psi at 17deg of timing with no meth. I'm out of injector so we couldn't push it more but it will handle 18-20psi i'm thinking once I up my injectors and throw bigger pumps in. Daily driven car that will see the strip here and there. I've had good luck with br7's but just was curious what thoughts were with running a cooler fuel like e85 in comparison to say 93 pump gas granted I wouldn't push more than 12psi on pump.

this thread just made me laugh, Martin is one of the most knowledgeable guys ive had the privilege of talking to(especially when it comes to cams), I would agree if using nitrous that projected tip plugs are no no's but a boosted street car on e85 is way different. Ive ran ngk 10's on my nitrous car and never fouled them out either. Nitrous cars stay lean with little timing and are a whole different animal.

I personally run non-projected tip plugs in my car, but when you have customers that drive their cars 10k plus miles a year, don't read their plugs, don't change them ever and don't want to have any issues with drivability...you do whatever it takes to meet that criteria. This is just what we've found that works and that works well.

5791 on low boost low compression combos
7173 for a little hotter setups that really make some heat
7405 for the really heavy hitters
There is NO need for a non-projected tip plug on a blower/turbo application if it's tuned properly. The tip on this cold of a plug should not be glowing red on the next cycle which is what you combat by using a non-projected tip plug. Now on Nitrous deals it's a good idea because you are injecting a more oxygen enriched atmousphere into the engine and it burns hotter than fresh air compressed. This is when I use non projected tip plugs.
BTW there is no such thing as a TR7 or TR8 plug unless your talking about iridium plugs which are TR7IX and TR8IX. And those are both projected tip plugs.
The plugs I use above are also gasket seat plugs. They seal better than taper seat plugs and they will work in your LS1/2/3/6/7/9. Every one of those with OEM cylinder heads I have used gasket seat plugs in. When you start making power with a taper seat you'll see antiseeze (if you use that stuff) shot out around the plug!
