So I went to the strip today..
 

was alittle disapointed. Thanks to my not launching the car (1.6l diff) and the MBC spring being too soft (wouldent reach full boost in 1st, 2ed, and 3rd gear) my fastest time was a 15.2. Cecil dragway in MD. I did beat a turbo civic tho? haha. If I coulda launched the car, im sure id be around 15 or 14.9. Eatheir way, it was very fun, and the first time I dragged my car!

this is at 9 to 10 psi with 305cc injectors.

thats not that fast?
whats ur setup,
i was running 15 flat in my old civic
and right now my miata feels about the same as my civic did,
and im only at 4lbs

you should be running a lot faster than that with that much boost. have traction problems or something?

I pulled a 14 flat with lots of wheelspin on my setup, same tires too. A better driver could probably have pulled a half a second more out of it too.

ok, here is my fastest slip

r/t - .079
60' - 2.794
330 - 6.995
1/8 - 10.222 @78.41 mph
1000 - 12.948
1/4 - 15.2 @ 101.7 mph


you can see I did so bad because of my launch... im sure if I was confidant in the diff i should be in the 14s.. I had a pretty good 1/4 mile speed.

oh and I couldent do a burnout to warm the tires, the car wheel hops real bad.

it doesnt help regular street tires anyway. your 60' SUCKS, but beside that looks decent, remeber the car runs a 17 flat stock, so thats a decent gain

I usually trap at 77 or 78 in the eighth, with a 2.3 or 2.4 60 foot I run mid 9s in the eighth. With some good traction, you should be able to hit 14 flat in the quarter.

so bacially I have the power to hit 14s, I just need to learn to launch the car. It was my first time, and I dident wanna blow somehting up lol.

damn, after some looking around, with my 1/4 mile speed, I should be near high 13 secs. Ugh, I shoulda just launched the car one of the times!

No wonder cars pulled good on me till the 1/8 mile where I would then be pulling very good on them.

If you get your trap speeds up to 88 mph you should be able to time travel.

that should do it.

CD if you can hook and pull a 1.6 or better 60 that 100 mph 1/4 could put you in the low 13's if you shift perfect etc. Altogether the MPH shows you are making good hp but have a hard time getting it all down. My bet is you spun 60 ft or so. easily

r/t - .079 <---that sucked
60' - 2.794 <--- thats even worse,
1/4 - 15.2 @ 101.7 mph i laughed at this one

in comparison

this was me in my civic last year

r/t was .059
60' was 1.9 in a fwd turd
1/4 was 15 flat at 92 miles an hour



u should be much faster,
improve ur driving, tires, and reaction time

back peddle off the line, or get better tires, or both,
ur spinning wayyy to much
ur reaction time was not as good as it could be
and ur 60 foot was absolutely horrible


the good news is ur car is much faster than u make it out to be,

u just need to tame it....

I know I know its just im afraid to fully launch it with just the 1.6l diff, espically witht he azenis, anyhting sticker would be even worse. Not to mention my car just loves to wheel hop really bad for some reason.

diff mounts....

dif mounts,
and try launching it just once, to see a more accurate time

Yea man, that's a good mph for sure. Can't say i've ever seen a car run over 100mph and be over 15 haha. Alot of good advice above, get your launching down and you'll be making some pretty impressive times.

U launch that diff with those tires and ur diff is gonna go bye bye.

I guareentee it :)

I can't remember exactly but in my stocker 1600 bogging off the line it ran a 2.6 60'. I also snapped the stocker diff that night. The only advice I can add is get a decent diff so you can smash it off the line.

Tim

All the more reason to do it, he'll be on his way to a 1.8 diff swap in no time once he blows the 1.6

15.2 @ 101.7 is funny to look at, but it shows there's a lot more potential there, i've never been on the strip before so i'm sure i'd suck but it's all in fun

aha, good advice.

and yeah, even with the bad time, it was alot of fun!

There was a new 911 turbo there, ran low 13s

my last run of the night last year, i got paired with an 89? gxt ....
dude had slicks on all fours...
and a 4 inch dump right under the driver side door, aiming right at me
ive never seen flames so big
dude dumped clutch at like 5k, and was off
he finished just as i got into 3rd
he ran a low 9.....

very depressing.

who did u pair against? how were the runs?
i want some fast and furious story here lol

Damn, I didn't know the old the old diff was that weak...

It's hard believe that 15+ sec miata had a trap speed of 101 mph. Even with a stall launch at 1200 rpm with 60' time of 2.35 I was able to run 14.7sec ET.
Man, with a 101 trap you will be in low 13s after you change that diff and nail it from the start. Here is a link the the 14.7 sec run.

thats a real high trap speed for that et. if you just slip the clutch a little more you'll shave a second or two off of that time. i only trapped 102 at my highest and i ran a 13.6 on stock tires.

Man, I was bracket racing a guy who has a dial-in of 17.71 sec. - My dial-in was 15.50 sec. Catching the guy was no problem, catching without breaking out of my bracket- big problem. The solution- easy off the line for a good reaction time and run the guy down. My reaction time was too good by .020 second which means red- the other guy wins! When I saw the red light I knew I lost so I made a no sandbagging pass. When I launch the car for full speed pass my 60' are 1.97-2.08 sec., 14.20-14.45 ETs, and 94- 97 mph. This clip show how important a good reaction time is in bracket racing.

NoCrash

Uhm... Just FYI: My best friends old LT1 camaro ran 2.8 60's, 13.2 1/4s, and 103mph trap speeds. You've got a LOT better time potential with a 101mph trap.

F&F story? well I lined up next to a civic that said turbo on the side (a la porsche) and he has some mad gansta lean goin on. So he pulls like 2 to 3 cars on me by the time im outta 2ed gear, then once I hit third I start pullin on him harder and harder and it was all over by the 1000 ft, beat him by 2 car lenghts. I did that twice.

well its nice to know I have such potental

uh wtf? lol..

Yea man, you should be high to mid 13's with a trap speed like that. I'm just basing this off of what other cars run at similar mph, so obviously there will be some variation but as you said always nice to know the potential is there. Keep us updated on your next visit to the track, i'm interested to see how low you can get those numbers(after adequate measures have been taken of course lol)!

big mph.

Whew, track days, it is going to snow here.

RT has ZERO effect on ET, and .079 isn't terrible, especially for the guy's first time to the dragstrop. Your time you are bragging about is only .02 - that's 2 one hundredths of a second - faster.

To the OP - as many have said, you just need to work on your launch. It is not easy on street tires, especially if you are running 200+ WHP on 205s or smaller. You have to find the sweet spot of the proper RPM to start revving at, and how quickly to slip the clutch. Work on that, and your ET should easily get to the low 14s on street tires, judging by your MPH.

Launching your first time at the strip can be tough, and scary.

My first time to the strip with my S4, I ran 14.2s with a 2.2 60'. That's in a 400 lb-ft torque AWD car- pretty sad. I was just too scared to dump the clutch and really hit it hard. Next time I'll hopefully see my times drop into the mid-to-low 13s if I drive better.

ya something is funny bout your car. do you know how much power your putting down because on street tires 12psi on a t25 making ~200whp my buddys went 8.6 @84 and then at a later date we put drag slicks on and did an 8.2 i think it was in 106 degree heat.

even though you didn't launch it hard if the car was making some power you'd see it pick up from the 330 to the 1/8 but its but its the same as the
60' to the 330

heres a great comparason turboed miata vs a stock one

sorry for the shitty camera skills but i think i see a 10.x pop up for the stocker

since when do people actually care about reaction times??? Just take your time and get a sick low 2.0 2.1 60 ft and you should be high 13's. How many times did you run?

you know what, my wastegate was a little loose. No wonder I dident build full boost in 2ed gear, may explain the crappy 330

ya reaction means nothign if i staged next to a fast car i usually leave on the first yellow lol

and 2.0 or 2.1 60'?? ohh heeeeell naaawz we wanna see those 2 fronts danglin in the air 1.6 or bust!! lol jk. get that waste gate snug and go have some more fun
