The NDRA has recently added a new class that has peaked my interest. It seems to be a class where I could be competitive. The main highlights of the class are FWD/RWD, 4 cylinder with 1 power adder/NA 6 cylinder/NA 2 rotor, full interior, and DOT approved tires only with a max size of 235/60 (no bias ply tires).

As of now I plan on attending the June 26th & 27th event at MIR, the July 31st & August 1st event at Maple Grove, and the August 28th & 29th event at Atco. I'd love to see some more Nissans out there drag racing! Wish me luck, I'll be proudly representing the SR20 community.

Here's the Honda-Tech link discussing the new class, .

I know of some fast Honda's on street tires but they were using the M&H Street Slicks and I think they are not legal in this class. I would like to run in this class but I wander what kind of times you will need to be competitive?? Mid 12's on street tires?

Look into the new Mickey Thompson ET Street tires, Jonathon. Hot Rod magazine did a test on them in this month's issue, and they perform *very* well. MT released them in 275/60/15 initially: Not sure if other sizes are available yet or not.

Atco, NJ this weekend. They are also running the makeup date for the Maple Grove eliminations. I qualified 2nd with a blistering 15.1 and a bad clutch. I'll be experimenting with a new clutch this weekend, hopefully it will hold. Hope some more sr20forum people show up. Last time it was just me and zexynx. Look for the most beat up sentra there and it will be me.

Good luck this weekend. Do you have a clutch/flywheel shield as required by the NHRA rules? I'm trying to figure out how to make/buy one of these for our trannies.

i raced in this class at the last Nopi meet at MIR, i lost in the semi-finals to a crx running 11.20's, trailored up from florida. my best was 12.82 on my old nitto drag radials. first time on street tires with turbo so i was pretty happy. i think with more practice and better tires i could have done better.(not 11.20's, but better)
