Doing some drag
My goal with this car has been to get an 11 second pass out of it on a street tire. The car is finally starting to make the power to do it and I'm getting all the kinks worked out. I took it out to a local crappy 1/8 mile track to see how it would do before I drive 100 miles to the nearest 1/4 track.
Traction was terrible, I was spinning into 3rd gear, but the mph seems decent. Really hoping it'll hook up a little better on a decently prepped track.

Thanks, I was pretty happy with the trap. The tune is actually still way rich, and I'm gradually leaning it out so I think there's a little more power in it. The trick is going to be getting off the line.
There was a Cobb AP tuned GTR trapping 90mph, and a C7 that was trapping 92mph pretty consistently. Made me feel pretty good that my shitbox had more topend than those two.
Here's the virtual dyno numbers. Blue pull was the first pull to redline on a new fuelpump. Red line was the tune I drag raced on (like I said, still pulling fuel in boost).

I've looked at drag radials a few times, but I just hate to spend that kind of money on a tire I really only intend to use for one trip to the drag strip.
If I did go that route, what would you suggest? My 205 Kumho V720's are mouted on 15x8's, but I hate to mess with those and I really don't want to buy more wheels. It looks like they're coming out with a 225 in that tire and I considered swapping out the rears to gain 10% more thread, but I don't know how much that would help. I've got a spare set of 14x6 NA wheels I could use. It looks like Nitto makes a 555r in 205/55/14 that's reasonably priced. Would that be a good option or do you have a better suggestion that's not going to set me back +$500.

Troy will say wrinkle wall slicks, I bet.
I would suggest Spec Miata Hoosier takeoffs as a compromise because they are free or nearly free. They will be slower than wrinkles but will be streetable. The rain compound is even softer and not hard to find, but does usually have a tread pattern.
I'm cheap.

I wouldn't do that.
My buddy tried this many times and they sucked more than his street tires.
He couldn't understand how slicks can be so bad, but road racing slicks are quite different and really not meant for this sort of thing (IMO)
You want soft wall, hard will just make it worse even if the rest of the tire is "slick"
Wrinkle wall or go home

Looks like the Nitto's I was considering are no more; not listed on the Nitto site and everywhere that lists them for sale is "out of stock". All the full slicks I could find are +$200 a tire. I would have thought there would be something out there in that size (or similar) for the Honda guys.

Agreed. I put Mickey Thompson ET Street radials on my 99 a few months ago, best thing ever. Went from spins from a roll on concrete to hooks in 1st. Now I have the power turned up similar to OP and it still barely spins 1st. I drive them on the street, luckily Houston is pretty dry.
