Oh and I wouldn't bring a dog that wasn't say, used to going to the gun range. They won't be happy unless they are used to sudden loud noises.

I didn't do as well as I'd hoped. No danger of getting kicked out last night.

I botched a couple of the launches, but a couple others seemed pretty decent. I'm sure I left quite a bit of time on the table just because I'm not very good, but I also don't think my car is as fast as it should be.

Can anybody give me any tips from looking at the slips?

How much does the car weigh? I really only look at MPH because ET is too inconsistent for most drivers in Miata.

Unless your car is a pig you just need more power.

Those ETs aren't horrible for that MPH.

do you have launch control enabled and the rpm dialed in? It only took a few launches to make a huge difference. Not having to worry about the throttle makes it much easier to have the clutch perfect for a no bog launch.

Do you have flat foot shifting enabled? I dropped over a tenth of a second per shift with FFS!

Are you using M/T drag tires, or some other good drag racing tire? You can go from spinning all of first, second and third to hooking in first, and snapping axles.

also, being in "the groove" of the strip usually helps traction.

I've never weighed the car, but it's an NB with a full interior, air conditioning, etc. I didn't even take the spare tire out because there wasn't anywhere to put while I was running. It's probably about as heavy as they came until the NC. Next time I go, I'll leave the spare tire and everything at home. I was almost out of gas, though, so that saved a few pounds I'm sure.

Can my car be a pig AND I need more power?? I think that's the situation.

No to all of those things. The second and fifth runs I really didn't spin much at all. Maybe a little bit in first gear, but not at all in the rest. The tires are brand new Dunlop Star Specs.

My car is a pig and I am running crappy toyo rain tires, no launch control or flat shift, I usually lose a tiny bit of traction at the end of first. Being in the groove makes a ton of difference, when you shift makes a difference too. I found about 65 to 6600 was fastest in my car.
My best 60' time was 2.048 my worst was 2.535, sounds like you just need to practice a bit and figure out when to shift.

your trap indicates you're making about 200-210whp

By all means, moar powah!
I usually trap close to 99 or 100 even on a crappy run with a headwind.

I need to get to a dyno. I want to be at 250, but I don't want to break anything to get there.

get your trap speed to 107-109 and you're around 250

How accurate is Virtual Dyno? If I find a flat stretch of road and do some 3rd gear pulls, would that give me reliable information?

All you need is more power. At your power no-lift shift, launch control, a better tire seem unnecessary to me.

I would think with those times you're probably a touch under 200whp. Add another 50whp to it and you'll drop way more time than any other little thing you could change.
