It's really not hard at all.... i'd suggest using e-brake instead of footbrake. You don't need to load it up hard, just a little bit.

My feet can barely handle a standard launch with controlled RPM at the yellows, I wasn't about to ask them to coordinate any brake/clutch/gas dancing.

All shifts were indeed at 7000rpm, or as close as my adrenaline fueled brain could get them, there were a few 7200 shifts in there I'm sure.

The botched shift wasn't to 5th, it just wouldn't go in. There's some fluid dripping from my clutch hard line where it goes into my brand new master cylinder, I may of been loosing some pressure there. Once my wife has a minute to help me, I'll see if I can see some bubbles there and do some further investigation. Otherwise, although my times sucked, I had a blast and that little clutch line issue seems to be the only gremlin after 10 runs.

What did you run in the 1/4?

you don't want to shift at torque peak, you want to shift well past the torque peak.

*edit: and if this vd is accurate

then shifting at redline is perfectly fine on your setup

Not that that's where I shift...but in my mind unless you're really awesome at drag racing, lets say peak torque is 6,600. By the time you react, it'll be later than that.

There are all kinds of theories on when you shift, but when it comes down to maximizing the full potential of your driving, you need to practice and experiment. How well the transmission shifts, driver reaction, and power all play a role.

Here's the real dyno, sorry, I thought I had posted it somewhere.

The dyno was all around fail too, I wasn't driving the car, and he wouldn't start below 2400 or go to 7000. The red line was an accuracy thing though, on the last run I told him to ignore the tach and go by the laptop tach, still didn't read 7000 on the dyno.

clearly you should shift at 5K. that's why you are so fucking slow.

:laugh:

no way bro, that's overspinning it like crazy.
his torque peaks at 4500

its all practice practice practice man.
get you a lil logbook and try different shift points and launchin rpm and take notes on what you did each pass. the easies and cheapest way to go faster is drive it better.
at least your at the dragsrtip. most of these 300 hp Miata fags wouldn't dare take their shit out there

If I was precise enough, I'd write down my launch RPMs and results, however those first 10 passes I was too nervous to look away from the lights. I went off engine sound, and was fairly consistent after a pass or two, slowly upping the revs until my epic launch that netted me my best 60', although that's the one I botched the 2-3 shift :(

Careful with the fag word, you're in a mod's thread with the admin regularly replying and you're insulting members with 20,000 posts. After all, it was only my first visit.

post videos of your 300hp miata at the drag strip bro.
we all need to take notes.

Why would you try different shift points? Stock rods bend above ~7200, so that's when you should be shifting.

Plus, when the stock rods bend it will lower compression ratio some so you can run more timing. Win-win!

lolol win

next time to the dragstrip ill take a video. my Miata only has around 200 wheel tho.

This is kind of a necrothread but wouldn't the mechanical advantage of being in a lower gear outweigh the torque loss as you near the redline? Unless your ratios are that close.

That's how I always thought of it, at least.

Typically, the fastest way down the drag strip is to be at your peak horsepower in a 1:1 gear at the trap.

Finally made it back. 9 years of hard labor, expensive parts, blood, sweat, and tears, and I managed a 13.5. This time at Woodburn drag strip with some co-workers testing a 335. Still shit tires (RS4), still shit driver (me), but I had a torsen, 1.8, and 250hp. 12s would be easy with a decent tire and driver.

Dang! this one was resurrected from the grave lol....

Congrats. Trapping 85mph in the 1/8th is not too shabby for a daily driver 4 cylinder. You are faster than my 06 wrx i used to have. It was mechanically stock but I mildly tuned up a bit with romraider. It only trapped 77mph in the 1/8.
