Can some have a look at this plug.

[GARY C]

Cool, Thanks...I have never seen that Berrymans in the store, but I like their products.

I have been using this for awhile seems to work real well

may check out the Berrymans see if anyone local has it.

Wow! I was not aware that it was even leagl to sell TEl retail. little alone ship it internationally. Cool

We're having problems finding a racing plug with a resistor, we do run onboard gps, intercom and the MSD COP ignition control 6LS #6012, http://www.msdignition.com/Products/Ign ... Crank.aspx
Anyone have thoughts on if we will have any problems running a non resistor plug? The reading I've done says that running a non resistor plug "may" cause "gremlin" like problems in your electronics, ie. ignition, gps, etc.

Thanks again.

ask this guy..

Hi Jason, thanks for your response. I looked on your web site and there is nothing that answered my question specific to my application. Any help from you would be appreciated.

Thanks

Hello,

We have a somewhat good reading on our website, http://www.ngksparkplugs.com or you can email pictures. You will most definitely have a hard time with the race plugs and finding a resistor.

Jason, we spoke on the phone a couple of weeks ago, we race Marathon/endurance Jet boats using the GM LSX454 crate motor http://www.chevroletperformance.com/lsx/index.jsp , with the stock GM COP ignition Coil GM # 12576016 and GM controller #19171130. We run the engines WOT for extended periods of time (20-40 minutes) at 5800-6000 rpm, peak torque is at 5000 rpm. We run pure LL100 aviation fuel. GM recommend running peak timing at 27 degrees for street use, we have the timing set at 25 degrees. We originally ran the stock plugs AC Delco 41-110 and detonated a piston via preignition, you recommended to use TR7IX which still seemed a little hot but we’re not sure as we’re just learning how to read plugs, do you have any specific and thorough literature on reading plugs for race tuning? Also, we would like to try some race plugs but are having difficulty finding resistor versions, will running a non resisitor plug cause us issues with our current COP ignition, GPS or intercom? Thanks again for your time.

Your situation is unique compared to most people’s racing experience because of the several minutes at a time you spend at WOT. I got involved in boat racing and pulling speed skiers 40 years ago so it seems normal to me that an engine must be adjusted different for an endurance race boat than the same engine in a drag race or roundy-round car.

How many pistons will ventilate and how many times can you see people say to use a #9 heat range before you decide a #7 is too hot? Furthermore, get off the fine wire fancy metal electrode bandwagon before it strikes again.

Is a flame arrestor or something rattling around on the top of the carb and knocking little flecks of material off the air cleaner mounting flange, or is something like that making some micro-dust of metal in the intake air?

Your picture doesn’t show down to the bottom of the ceramic. Can you see a distinct grey or black ring on the insulator with a clean area below it?

If you run a too-hot plug you will have to jet rich enough and retard the timing, do whatever it takes, to keep it from getting so hot as to start preignition again. You see what that leads to.

Use a MMT octane booster in your 100LL in a ratio of 1 oz. to 5 gallons. I use a 12-14 oz. bottle to a 55 (US) gallon drum of 100LL. When you go to get the #8 plugs, check the octane boosters at the store and see which ones are labled "Contains MMT (methylcyclopentadienyl manganese tricarbonyl)" and use it. MMT raises the octane of 100LL several whole numbers. It will impart a tan orange-brown color to the plug ceramic. Too much will look like a wet brick. If the plug is too hot and there is too much MMT it will look like a shiny glazed wet brick.

With the cooler plugs, 26° should be OK, compromise, 25°.

Any recommendation on Octane boosters with MMT? I've found a couple including Lucas.

Amsoil, Bardahl, Berryman's, NOS, Outlaw, several others, read the label, make sure it says “contains MMT” on the bottle. Keep an eye on the plug color. If they get to looking a dark red-orange like a wet brick color, don't use so much.

[racer189]

If a person had a maximum of $1000- $2000 budget for tuning tools for this NA Carbed application(EGT, AFR/O2 or a 5 gas analyzer (anyone make a good handheld unit in this price range). Can a person reduce the learning curve by just using one system, and if so which one? I'm thinking about using a Racepak Data logger system which gives me the option of either EGT or single/multiple O2 sensors.

Thanks in advance.

Here is another one, most of their systems do multi point data logging.

Found some "V-Power" racing plugs that may work for this application. They're suppose to require less voltage than a conventional plug to fire so hopefully the stock COP ignition should handle it. The only drawback may be the reach.....factory specs designate .708 and these are .691. Will a .017 shorter reach be a problem?

Anyone have any experience with these V Power race plugs?

Any issues running a Non Resistor plug in a racing application?

Any issues running a Non Resistor plug in a racing application?

All I can say is that many have done it in the past. I think it depends on your wiring schematic and sensitivity of the various systems involved. The best plugs are always going to forego using a resister.. and race cars run computers too.
