The NT555 has been around since about the mid-1990's. I wouldn't count on it for much with the power you're making.

I never was much of a Michelin fan back when their tires weren't as good in the wet as a number of other tires. But that's very much changed these days.

Thanks Norm.

I’m honestly up in the air on my next tires. Hopefully it will be awhile. I might have to start driving it daily come spring due to work changes.

I don't drive mine in the rain there is no point, it's hard enough to hook up in the dry if your just mucking around at speeds between stopped and the speed limit

This is the kind of real world data I suspected. Again, I love HP as much as the next guy but there seems to be some serious hardware (and software?) involved to making it perform. Thanks all, for indulging me.

I ended up with 610 rwhp and with stock suspension could not use 1st or 2nd gear full power. Put drag radials on and ended up rebuilding the entire rear suspension and rear cradle. Also cracked a gear in the transmission and spun the tires on the wheels. The cost of added power can be more than just the power adder but is addictive as all hell.
