Hit the drags today

Well I didn't get what I wanted but the good news is that the car is definitely capable of it. I have done nothing to the car, it is bone stock. Which to many people's amazement when they were checking it out. Yes a lot of people were very surprised to see me at the grudge match today. Here's what my setup was.
I don't know what the temp was outside but it was damn hot. I was sweating through my shirt pretty quickly.

Setup:
No spare
Mixture of 91 octane and 103 race gas Unleaded.
Roughly mid 80's or so outside. Not sure but it felt
pretty hot out.
I don't think we're that high above sea level in Carlsbad.
Don't know exactly but I'd guess a couple hundred feet at
most. Could be wrong. I'll need to check into that.

Anyhow here's how it went. Don't want to make this too long. This is my first time launching an AWD car. My gripe about the car came to bite me in the **** as well which you'll see.

First run they screwed me over on the staging and threw me off. Here in Carlsbad they don't care too much for imports. Big domestic crowd. So I staged second and when I did they tripped the lights immediately after he had finished *****ing at me about my helmet strap not done correctly This threw me off but
I didn't care about my reaction time I just wanted to practice my launch and 60'. 1st run was horrible.
60' 2.45 secs
1/4 = 14.6 @ 98mph

2nd run again they ****ed with me. I got their first this time and was waiting. When the other guy staged I started to rev to prepare for launch and he just waited. I drop my rpms down to wait for him and when I do he trips the tree. *****! So that screwed me up.
60' 2.0
1/4 = 13.8 @ 100mph

Damn 13.8 with a 2.0 60'. With this I know the car can do a 13.5 with a better launch.

3rd run this is where my biggest gripe in the car bit me in the ***.

60' 1.8 BOOYAH!
1/4 = 14.1 @ 98
My big gripe with the car is the damn gearbox. I missed the shift into 2nd just like I feared would happen. It didn't even want to go in so I lost a good .5 second at least. I was so pissed off.

4th run same ol
60' 1.8
1/4 = 14.1 @ 98 missed 2nd gear again!

But the good thing is I've learned to launch the car a little better. There was a guy there getting 1.6 60' that was trying to tell me how to launch the car but I didn't have time to try it out.

methods:
1st run was a clutch slip around 6K. Not good Slipped it too long and burnt the clutch.

2nd run was a clutch dump at close to 6800 rpms I was feathering the gas for turbo spool but was unfocused cuz of the a-holes at the track.

3rd run featherd around 5500-6000 where I wanted it to be. Let the clutch out for a split second about 15% enough for the tires to grab then full release and gas mash. Good 60' but missed 2nd gear.

4th run was the same as above.

People seemed really impressed by the 13.8 since the car was 100% pure stock other than gas mix. I know I would've hit a 13.5 at least if not for the crappy shift problems. I'm not the best drag racer so someone with better skills and 60' times will be low to mid 13's. Gotta love this car.!!!!!

Was the guy running the 1.6's in an Evo? If so, what was his 1/4 mile time?

Hmm... maybe you should drop to 2nd sooner.

You should try some double clutching, even with Synchros, makes the Synchros more tolerant.

Here's an article to help you out:

Hmm... plugging a few numbers into a generic 1/4 mile dyno calculator, your 100mph trap speed seems to equal 275bhp, assuming car and you are at about 3450 pounds curb weight when staged. Strange eh, considering so many are saying the car is underpowered...

See what I mean over here: Horsepower Calculator

And yes, I know these things are a real WAG, but still kinda interesting...

If you were able to get the 1.8 60ft times i'm sure seeing 13.6 shouldn't be a problem.

No the guy was driving an Audi S4. He said he was running 12.8
with the car. Modified of course. I'll have to try his method sometime cuz it sounded interesting but it's not something you could sit at the staging light thinking about.

I thought about tyring to shift sooner as well. I'm thinking I'm taking it too close to redline and it's making the shift more difficult. I dunno. Everything I've ever read about double shifting basically says not to. I'll check out that link but so far it only seems like a waste of precious time.

I think if I didn't screw up those runs I would've seen a 13.6 easily if not 13.5 or 13.4 with a possible 101mph trap. I mean it seemed like an eternity went by before I stuck it back into gear. I know I lost a minimal of .5 second on those grinds. I had one guy beat out of the hole and had a sizeable lead on him till I grinded. Then he past me and I was playing catch up. Well, next time I will definitely post better times. I fully believe the 13.5 someone else got cuz I think I would've hit it as well on a clean run.

How far back do you put your seat? I found that I have to move the seat quite a bit forward to use my clutch better, and I am 6'3".

Another thing is to check the adjustment of the clutch. I have seen my own car, where pushing the clutch pedal to the floor, actaully was worse than just pushing it in to just off the floor. Adjusting it corrected the issue.

Yeah, I would say shift sooner, don't take it to redline, you are not optimizing boost then, shift at the top of the boost curve should net you better times. Not to mention close to redline the synchros may not be as efficient.

You should try some double clutching
Please don't double clutch when drag racing.
Plain and simple speed shifting is best for drag racing. Keep gas pedal planted to floor the whole 1/4 mile and shift as fast as you possibly can. Smooth and quick..pull shift lever fast and press/release clutch as fast as possible all while gas pedal is to the floor.
Might sound dumb telling people this....but some people really don't know. I've seen so many people at the drag strip letting off the gas between shifts and granny shifting. It's so funny seeing people run 2 seconds slower than the car is capable

I've never double clutched in anything before and I power shift or "speed shift" as you said at the strip. From 1st to 2nd though I lift a little on the gas because it runs through the gear so fast and I don't want to bounce off of the rev limiter. Other than that it's pedal to the metal.

Well on the 13.8 run I had a crappy 2sec 60' time. But my 1/8 ET was 8.888 @ 79.19 I need a clean run with at least a 1.8 60' and I'll lay down a 13.5 or so. I've gotten down my launch for a 1.8 60' I just have to keep from missing my shifts
