I am about to install my 2.8" pulley and ported blower, to bring the car up to approx. 500 hp from around 410. My current stock goodyears are shot on the rear. I want to put new tires, do I even need to increase from 275 size??

No, just get some good drag radials in that size and you will be alright.
Huh. I have R888's in 305, cold weather I spin 2nd to redline at 519/567.
You don't ever need to run 275 and you can run smaller. Think 15x8 MT Drags at super low psi. If you would like to run a "normal" street wheel tire combo 275 prob. isn't going to do it.
Actually it's a daily driver so I don't want a DR, with that said do you think an NT05 would be fine in a 275 size?
I have to say with the current power level, the wheel hop is horrible in 1st and 2nd, I can't imagine how bad it will be with 80 more hp.
What's the point of the extra power then? It's either get a decent tire, which you can daily the Nitto 555r's, they just don't hook as well as the others, or get the Full tilt bushing kit. Or do both. I don't understand why people want to run around with useless power. It's much more fun to drive when you have traction. I'm sure someone else can suggest a decent tire that isn't a drag radial, but it won't be the best for traction. Good luck either way.
Have you ever punched it in 4th gear entering the interstate? Thats why I want more power. If I can ever figure out the wheel hop and traction issues, then I will love the new power in the lower gears....
100% stock, 1st gear is useless in my car. Now with simply new plugs and CAI, and balder tires, 2nd gear is now becoming useless....
So with a soon to be turned up motor, I am really concerned about traction / hop issues.
I simply want to reasonably do what is necessary to eliminate the wheel hop and tire spin. You say use R tires, but 5 others say no on a DR due to rain. What gives?
You had better do some IRS work, either MM Race or FTBR. I have MM Race and it's great, but many here have FTBR (Full Tilt Boogie Racing) and have nothing but great things to say. That will help your wheel hop issues.
However, after the IRS work, I would still go with a 10.5" wheel and 315 tires. Get as much traction as possible. :banana:
Then you need to get an IRS bushing kit (Maximum Motorsports Race kit or Full Tilt Boogie Racing) and get 315s (I use Nitto NT05 non-DR). Easy as can be. Wheel hop issue solved. Traction issue solved. What else do you need to know?
I'm right around 500. Running 295/35-18 BFG KDW2's on the rear. 1st gear takes some work but hooks about halfway through, 2nd will chirp but finally settle in, 3rd chirps and it's solid from there on.
That's also with the tires warm. Cool tires on cold concrete just give it up, you're not going to find anything that will hook.
Price everyone's R compound DOT road race tires and buy a pair that are reasonably priced. Toyo R888s are a great tire but not a great price.
An R compound that is not a drag radial works fine on the street and in the rain.
They don't last very long but NOTHING is going last very long at this power level and above, so you might as well buy something that allows you to use your power and have some fun with it.
