Drag racing tonight - two questions
 

I'm taking my car to the local 1/4 mile strip for street night. I've never done a 1/4 mile, and I've only done the 1/8th one time with a stock miata about 10 years ago.

Question 1: How fast can I expect to run with an NB2 at 11psi on a 2560? They require a roll bar if I am faster than 13.5sec, and I would hate to show up just to get one run and be kicked out. I won't be that fast, will I?
Question 2: Should I bring my dog? Mufflers are required for street night, and I like to make a habit of taking the dog most everywhere with me. I can't find whether he's allowed, and I don't know just how loud the cars are even with mufflers. I wouldn't hesitate to bring him to an autocross, but this is not an autocross and dogs have sensitive ears I hear.

In exchange for answers to these questions, I will post time slips tomorrow.

Just show up and get kicked out for being awesome.

Bring your dog. Dogs are really sensitive to sound and will probably orgasm with the symphonic cacophony of man made marvel. Just stuff him in the trunk, don't tell anyone. Just do it. That way, when you get kicked out, you can have your dog sit next to you in full glory as your chariot departs from the scene, leaving an impression on everyone.

"Don't fuck with me, I drive a Miata with a dog."

Woof motherfucker

i didnt realize people owned miatas without roll bars.

Do not take your dog, what is he going to do while you are racing? He surely wont be able to ride with you.

umm, no they won't let you race down the track with a dog.
as for if he's allowed at your particular track, as a "spectator" I don't see why not.

2560 on 11 psi doesn't tell us much. if you're around mid 200's you should be in the low 13's. If it's your first time, you will likely not run anywhere near that. These cars are tricky to properly launch

Yeah, there's a few hundred thousand of us.

There will be 3 of us with 3 different cars, so I was planning to leave the dog with the others in my group when I was actually racing. I don't have a helmet for him so I wasn't even considering letting him ride shotgun. That would be unsafe!

I am guessing mid-200s but I really have no idea what I'm making for hp. I have the 6spd and 3.9 rear also. I will probably struggle with the launch, as I have a really hard time being hard on my drivetrain. Sounds like I will at least get a few runs in before I break the 13.5 mark.

you should definitely get a helmet for your dog

I think I'll leave the dog home this time, and if I don't break 13.5, I'll bring him next time if the noise and atmosphere seems reasonable. Or I'll leave him at home if it does not.

if you can't run 13.5 in a mid 200's Miata, you should just let the dog drive :giggle:

Dog in the trunk. Why is this so difficult.

Looking through some old times in a 6sp 3.90 NB I've run:

13.6 @ 105 at 212whp
12.7 @ 113 at ~270whp

That should give you a nice range of what to expect. You better get kicked out!

pdexta is right on the money with those times/traps

Hmm, so 270whp from a rotrex and 6sp 3.63 NB should still get into the 12's? I obviously wont have the same torque curve.

Good luck at the track man! I'd still say bring your dog, many dogs come to the track with their owners, there is only one way to find out if your dog doesn't like the noise. And it is fucking loud. But if your dog likes it, or doesn't mind, how could you not drive with your buddy!?

Any thoughts on whether the trunk is a safe space in a miata without a roll bar?

I usually install a roll bar in my trunk so my dog can use his harnesses
he helps me datalog

Not all tracks will insta boot you either.

Most if not all will give you a warning after the first one.

Some as long as you have a helmet wont care at all or will just tell you to finish the night out and next time come back with xxx equipment.

Good luck.

Now I see where Hard Dog got its name...

True, and I doubt they'll notice you anyway. It's not like a mid-13 second car is going to attract a lot of attention at a drag strip.

They definitely notice a 13 second miata at Sears Point, not too many run that quick. It also seems like everyone loves these cars.
There they say "don't do it again", but it doesn't become an issue until you put your dial in time on the window. They won't let you dial in a 13.4 and run with no roll bar.
All that being said there is a ton of leeway in the first 60', if you go too fast just do a mellow launch. I picked up over 3 tenths in my 60' time for my best 13.58 @ 102 with 2.07 60',but I also ran a 13.8 @ 102 with 2.4 60'.
