Spark Plugs for 500rwhp
I've heard of the snow mobile ones being used. Is there any performance difference between those and the greddy or hks plugs? I don't think I want to spend 35 for each plug but I have come this far so why not if I have to I will.
10 or 11 heatrange or what? and would I do that just for the leadings or both?
And where do I get whichever plug you've suggested for the best price. I do need them by Wednesday or so of this coming week.
Thanks team

I am at 410 rwhp and my car does very nicely with BUR9EQP leading and BR10EIX trailings (gapped at 0.022).
At 500 rwhp, you might need to move to 10s in the leading and 11s in the trailing... but since I'm not there... I don't know
*edit* to install the BR10EIX, you need a thin walled plug socket. You can spend a bundle and BUY one, or you can just take a 2 dollar regular thick wall one and carefully grind the end to a slightly smaller diameter with a bench grinder.

There is a guy that sells the thin walled plug socket here on the forum. If you do a search in the for sale section for socket you'll probably find him....look for old posts like over a year old. I think he goes my metalman. Seems like its $20 shipped.
I'd either tun the B10egv plug all the way around or maybe B11egv depending on what kind of fuel and how much boost this is going to take. The B10egv makes an excellent street plug, mine never fouled. Dont know how the 11's will do in a street car thats actually driven around town a lot. If I had to guess I'd say they are probably ok since the 10's last so long.

The EGV and EIX plugs mentioned are available at motorcycle shops, the EGV are standard plugs and EIX are iridium. There are also platinum plugs of that style that would work, but platinum doesn't ignite as well or last as long as iridium.
I'm running EIX iridium plugs, 8's leading and 9's trailing in my car which is mostly stock w/ a downpipe. The 8's are fouling a bit too fast, I'll go back to 7's soon I think. I ground my own thin-wall socket, it took a LOT of grinding. A premade tool would probably be worth the $20.00 in the time and mess it saves.
edit: bought mine at www.chaparral-racing.com

Right now I am running 9s all around at 12 psi and about 340 rwhp with no problems. Once I move up to 15 psi and above I plan on running race in the leading again.
The b10egv's that stephen (spo) mentions sound like a great idea for your (and my) application if they really don't foul out that quickly. That might be the best way to go.

Actually, I am thinking of trying the br10eix's on this link:
http://www.chaparral-racing.com/Chap...7DBAA1D68135AF
and getting a thin wall spark plug socket from keith www.kgparts.com
I think that setup would work good for ya, yanni.

According to NGK , the IX plugs are better all-around: won't foul as quickly, and produce a better spark.

However, according to their tech info, the 'standard' face used in the EGV and IX plugs might dissipate less heat than the 'rotary-specific' BUR7EQ plugs with the flat face, which is reportedly designed to reduce chances of flooding. The RX-8 comes equipped with a standard face 'OE Laser' NGK Iridium plug, but their engine does not produce as much heat as ours does, so that would be like comparing apples to oranges.

Re: the plug socket, just plunk down the 20 bones and buy one from keith at www.kgparts.com . You'll get a lot of use out of it

I ground my own plug socket, bought a cheap one from the motorcycle parts store I found my plugs at, and ground it with a grinder. It took a while to get it to the needed thickness (or lack thereof) but it got the job done in the end.
If Steve Kan is coming to tune your car, you might be best off to buy a few different sets and heat ranges, and install whichever plug he recommends. Spark plugs are pretty quick like that.

Question: Do hotter plugs require a richer mix than a colder plug would? And what sort of HP limit is there if you run 4 7's? I'm not quite understanding all this.
