spark plugs?
 

I tuning my car at 10 psi now, but soon i would like to run 17-18. What spark plugs are you guys using? 9s and 7s......or all 9s......or all 10s. If your running 10s where did you get them and were they worth the price. Did you notice a difference and where is the cheapest place to find them?

I have been running all 9's at 17-18 PSI for 9 months, and everything seems ok.

Gary,you need to explain you're problem with all the breaking up at high Rpms.That will help them answer you're question.

MODS?

My mods are..well...it might be easier listing what I dont have...A street port, T04S, exhaust, Wolf 4.0, 550 and 1200s, Taylor wires, Crane HI6, front mount. I think my missing has to do with tunning, so that can be fixed. If 9s seem to work than thats what I'll go with. Eric, hopefully your back in time to see me dyno it, I set it up for the 22nd.

Do a search here on the NGK B9EGV and B10EGV. I just switched to them from the BUR plugs and am happy...

Gary hopefully I will be back by then....Nick said he wrode in you're car and was impressed,he said you would wax his supra.:)

Dang...i'm out of town that weekend...I'd love to go with yah and see that bad boy on the dyno...

I put new bur9s in and it seems better, I think I'm going to try those 10s, thanks for the info. Eric, did Nick really say that, make me feel good. That was at 10 psi and "Garys" amateur tuning. I beleive I can make the same horsepower at 10psi that I did at 15 on the stockers.....KICKASS........Any way I tunning the new Wolf today on the street with Ryan for the higher load points. It only took me about 3 to 4 hours to get the car running for the street, not bad. We miss you up here so hurry up bitch.
