I use it.
10.5 for leading, 11 for trading.
It's really good and I love it.
But I hear no one wants to buy such expensive spark plugs.

Zoog, are you really getting 360 to the wheels because your mods just dont support that at all and if I had your mods I would just use #9's for the street and if you do a track event I would then use #10's or 10.5's but for everyday driving you just dont need to. IMO


-Rikki
i know that my mods don't support it, but the numbers scared everyone at the dyno including my tuner ( MZM performance ) no one expected my car to do that. everyone expected high 340s but i guess i got lucky.
i'll be glad to scan my dyno sheet as soon as i get back to the US, i'm out of the country right now.

stock turbos....is the wastegate ported? Should be if you are running a mp.

I have just about the same mods as you and I put down 288rwhp. Only exception is the mp and ic. I have a high flow cat from n-tech and stock ic (for now ) What I am getting at is not to flame you or not believe you but I use 9's all around and I don't have any problems. I would only use 10's at the track if I were you. $100 for all 4 is pricey!

no, the WG is not ported, but i don't get any boost spikes but it goes to 15 psi sometimes on a cold night even at low settings with the profec B. if you guys don't belive me go to www.mzmperformance.com and get their number and call Mohammed or Mutsim and they'll tell you about the mods or if anyone is in texas they can go to their shop and they have a copy of my dyno. or call colvin automotive and ask them about the stock motor and stock turbo red RX7. i also did a THIRD gear pull at protech performance dyno in Austin,Tx and did 335 whp.

how much boost were you running? what A/F? and who did the tune'n because that is awsome if true!!!
I just went to the dyno and put down 337HP @13 with a very good A/F 11.9 and 321HP @10psi A/F 11.9
I am very pleased with those numbers but 360 had to be at least 14-15 psi
i ran 14-15 psi to get 360 whp but i didn't use a wide band because my mechanic was sure that the car is running rich and didn't want me to waste my money on the wide band. i'll do another dyno when i come back and i'll be sure to add the A/F . as for the tuning i have a Pettit ECU but Mohammed at MZM installed a fuel pump and did something(not sure what) to the fuel system also.

Rikki I bet you could have pulled off a higher number with the 13 psi... Maybe your IC was getting a little heat soaked standing still. I wouldn't be surprised if you got up to 350hp.
