1.6 Artech SR20 200hp 1/4 mile
2 Attachment(s)
Shit times, but it was my first time, with an open, x6 heat cycled Neo Gens....and I'm sure I'll think of some other excuses.
I'm 526J, my friend in the other lane is a 300+hp FWD LSD Galant on RS-3s, in major need of some drag setup tweaking. Currently both our cars are floating between DD and full track circuit duty. Both do exceptionally well at both. https://www.miataturbo.net/attachmen...ine=1375595253 |
I kind of want to try this now.
|
Any idea what the car weighs?
|
2150+ my 185lbs. I cut about 50-60 lbs out race trim, I didn't do any prep for this though.

Does the Galant weigh about 4000lbs?

The eighth mile is what is killing you. You have enough mph to go in the 13's. My guess you will see that mph go up if you worked on your driving. It takes a little practice.

Botched 2-3 shift. I saw huge improvements over 10 runs, definitely need practice. I have no idea how to properly launch a car, much less a turbo one. Well, I do, I just can't do it.

I ran 16.5 with my stock '90.
I understand that there are launch, shifting, and traction issues, but only two seconds faster for the double the power seems strange. |

My technique: Roll until staging light comes on. Stop. Right foot holds brake pedal and side steps throttle, left foot releases clutch enough to feel it start to grab. Yellow light before green, I slip my foot off the brake fully onto the throttle at the same time as I dump the clutch. Then it's usually wheel hop for a few shakes, when my tach his 7,000 I bang second and repeat with each gear until I cross the finish. If you set your rev limit to like 8,000rpm's, you might cross the finish in 4th. Nothing sucks more than to put it in 5th right at the finish line. |
The botched 2-3 shift sucks. I've done that a pile of times...go for 3 rd and put it right into 5th.

The track should be flat enough that you will not roll when staged. For a Miata, I always come out at a high rpm whether I am driving with a power adder or not. You never ever want to bog the motor. Some excessive wheel spin is better than bogging. Most of your practice will be learning how to modulate the throttle at launch to match the tire you are using. Once you have that figured out, then you work on shifting. You need to experiment with different rpm shift points. It takes a few passes to really nail it down as to when is the best time to shift. I looked at a few timeslips I had, and I started to get into the 13's @ 95 MPH when I had the less than ideal 95 cylinder head. That is of coarse with a good tire. You might have a hard time going into the 13's without a tire change, but I would wager that with practice your mph will go up some. It might be enough to get you there on the tire you are currently using. |

LOL at ONLY 2 seconds.

This may also be why i have good luck with my transmissions, despite having ragged most of them at the strip. |

The brake is often used to just barely load up the motor so you don't shock the ever-living shit out of the drivetrain.

In my opinion, you should dyno and find out what rpm your torque starts to drop off at...that's the rpm where you shift.
