Default Took the 02 Z28 down the track for the first time yesterday.

After starting out and getting a series of 13.7 passes, I switched my launching technique (inital rpms at 3500 instead of 2000, and having the clutch almost engaged at the launch. This netted me:

R/T: .204
60': 2.275
330: 5.953
1/8: 8.929
MPH: 83.07
1000:11.457
1/4: 13.595
MPH: 106.28

That was the best run of the night. I know the car still has more in it, I'm just trying to find ways to coax a few more tenths out without mods. All the car has now is a lid and shifter. And yesterday it was 85 and sort of humid. Any tips or ideas to improve my time just by driving technique, not mods. I want to get good at driving the thing before I start dumping money into it.

You need to get that 60 ft down and you will greatly improve your ET. The MPH is good.

Yeah, my shifting is decent but my launches are pretty bad. Any tips on launching? How do you do it?

Yeah your 60' time sucks, but you will just have to find out what your track can handle. You may have to baby it off the line if you are spinning.
Also give your car some time to cool down after arriving at the track. I know once you get there, you are ready to race, but if it cools for about an hour or so, you could see some big drops in ET.

I know you don't want mods...but would you consider a stickier tire a mod? I have had some better luck with the MT Drag Radials.

Thats a good idea. How aggressive should I be on launch?

You said you want to be a better driver, I would really recommend the tires b/c as you gain power in the future they will become more of a necessity. Knowing how your car reacts to different tire pressures for instance will really help you. When I made the switch from true street tires to MT Drag Radials it almost felt like a different car. My launch "style" changed immediately. Just be careful with sticky tires, a stick, and a stock 10 bolt.

I'm definitely not saying that there is no room for improvement. To be honest, I don't even know what an almost factory 6 speed should be doing for 60'. All I am saying is that tires should help you, and they will prove to be even more effective as you add power in the future. Like I said before, though, you will want to be careful using sticky tires on a 6 speed with a 10 bolt. I have run my 10 bolt for years now with no issues...but I also have an auto; many others are not so lucky.

The launching is going to be different for each car, I've never been to a strip yet, I need sticky tires bad. You just need to figure a good RPM where you won't bog off the line but also you don't want it too high that you blow the tires off. And good tires will help as well, just gotta get it down, I've been trying to go to the track but can't really find time after work.

My best pass was 13.07 @110MPH on the stock tires. This was with the cat back and lid. I knew she had 12's in her, so I bought the BFG drag radials. First pass she bogged, next pass I smoke the stock clutch. By the way the car only had 10K on her at the time. As soon as you get tires make sure and have enough for a new clutch, cause that will be next. Once you have the tires and clutch, start saving for a rear, the weekest link is always next. Just my .02

UPDATE:

Ran the car tonight:

3 runs in came up with a :

R/T : .015
60': 2.198
330: 5.823
1/8: 8.758
MPH: 83.70
1000: 11.260
1/4: 13.385
MPH: 105.74

If I just got to a 2.19 and its running 13.3's, theres definitely still something on the table.

i understand your issues. I usually have problems with traction or it bogging. I just can't get them down well. Some sticky tires is a must

If you can get that 60ft down to 20. you might run a 13 flat or even a 12.9.

I ran a 13.17 @ 106.7 with mods in sig minus !AIR/EGR and the LS6 intake through an A4 with 16in. Snowflakes....

You sure it was 119?? Thats VERY high





Also about the launch, I just slip the clutch, hope the car doesnt bog too much, and doesnt spin.
