Colder plug = a rich tune?
Colder plug = a rich tune? The car was running 12.8-13.1 AF on the TR-6's.. I switched to a colder plug and it was at 10.5 AF at the track.. So, I was like WTF? Does going to a colder plug affect the AF ratio?
It was all good... Only think I did was change the plugs to TR7's and loaded her up on the trailer and hit the track. 1st run NA was actually 10.2 - 10.5 AF... But, the odd thing was on the NANO 100 shot the AF was 11.8-12.4 AF.. WTF?

Thats wierd. That plug should not make that huge of a difference. Taking the filter out will chenge things alittle. I wonnder if the two together just made that large of a difference. Put the filter back in see what it does..

Dont think it was that, i had problames with that before and fixed it... Its all good to go now, heading back to the track to nail the AF down.. Just orded some new shocks and going to see if a DR will work better then my ET streets.
The plugs can cause it to richen up a touch as the combustion temps will be lower, but not as much as you're seeing.
I'd stick with the bias ply tires, the radials might work, but there's no guarintee, the bias ply almost always work.
From that picture, I'd get a rear swaybar on the car, it's rolling over pretty bad

The radials will work and be faster than the et streets or slicks. The car gets up on the tire much faster. but be carefull you have to run the front shocks a good 3 clicks tighter or you will end up on the bumper.
Those things are like trying to hook on Nitto's
Maybe when I get the car back out after my break for next year. I'm gonna minitub the car so if I can get at least the 295 in it I will try them again. If the 315's will fit, I'll just start with them, see what that gets me.
