My first two runs...

[link16]

My first two runs ever, not just on the DSM....

1st run:
R/T ... .075
60' ... 3.566
330 ... 7.764
1/8 ... 11.021
MPH ... 76.37
1000 ... 13.765
1/4 ... 16.103
MPH ... 98.98

2nd run:
R/T ... -.011
60' ... 2.773
330 ... 6.873
1/8 ... 10.097
MPH ... 76.01
1000 ... 12.859
1/4 ... 15.211
MPH ... 98.54


On my second run I had the clutch all the way in, and I drifted foreward. That was why I red lighted it. Both runs I was shifting at around 5k rpms.

This is a pic of my slip.

You should be in the 14's you need to learn how to launch the car better, you can rev it out a little higher to next time.

 

[link16]

I was at the track again tonight and my best pass was a 14.72 @ 98.89MPH. My 60' was 2.51. That was my worst 60' all night.

This is on premium gas, on bald street radials running 8psi.

DSM's were few and far between at the track today and I was disappointed, I saw Whotippedmycow though.

Gread day, I can't wait for either wednesday or friday of next week to see whatelse I can get, I am still at about 15 or so on the AFR.... I ran a 14.86 before I tuned anything.


Enjoy guys, I will keep updating this post to keep those who are interested.

Better tires for the win.

Nice Link . Yeah, the 60's should be lower, but that comes with practice and finding the right launch technique for your car and your power. Yes, better shoes will automatically lower your times. You are probably losing time on your shifts as well (tire spin). Also, if you aren't already, "no lift shifting" will help a lot.

One thing you may want to think of is your shift points. Our cars generally have a peak power set-up at 5500 to 5800 (depending on your set-up). If you are shifting at 5k you are probably short shifting. May want to think about shifting higher. I like to shift after peak power so that I fall down on the next shift into the up ramp of my power range. That generally puts me close to my torque peak. BUT there are lots of different theories here, Just a little "IMO".

Maryland huh? Are you running on MIR by any chance? Too bad season's coming to a close. But at least you are getting runs in

"No lift shifting" is a bit bad for a DD on the origional tranny...

I will be at MIR tomorrow for Domestics vs. Imports World Cup. Hopefully I will put down some better times, I am going to try and lean her out a bit...when at WOT my AFR is about 16...That might kill some power right there.

I was hoping for you to get into low 13's this season Bullet.

WAIT! Maybe you got a typo here but you wrote that your AFR's are 16 WTF? That's a' big time lean. I know lean is mean but that's a bit dangerous. I did run 16's on a run one time when I got pissed at my set-up and it wasn't doing what I wanted it to do. But my expectation was that I could have blown up a piston (I didn't and it ran the best time of the night, go figger). I'll wait and see if there's a typo in that.

As for NLTS, I do it with our cars as a daily driver . But then again, I got 2 more ready to go in .

I'm very, very jealous of you going to MIR tomorrow . I'm thinking I got one more shot on the 11th at E-town to run (street wars ? or something like that). If I go, I'll probably bring the DD.

Good luck on the runs and think about the shift points.

Well, at the current moment I have the narrowband.... The narrowband reads from 14-14.8 IIRC. I leaned the whole setup out 10% and I am still pig rich off the charts at WOT and any form of boost.

I must not understand the No lift technique...I would expect that to be shifting w/o a clutch....I won't do that as I payed more for my clutch than I did for the spare block.


I hope to do much better tomorrow....

No lift is you don't lift your RIGHT foot . I actually have my clutch set to engage high so that I can just tap the clutch and shift while my throttle stays 100%.

PM sent on the other info.

Well, I am back to update one last time for this season.

I finally put my transmission in...It seems to have different gear ratios from my previous transmission.

I will list everything on the slip as I still am having troubles taking pictures of it.

The track was VERY cold last night, I couldn't get grip if I tried.

Here is the slip:Car 456 (same number as MIR)
R/T... .737
60'... 2.442
330... 6.480
1/8... 9.625
MPH... 79.02
1000... 12.307
1/4... 14.570
MPH... 100.08

Track temps were at 58* F
Relative Humidity was 67
Absolute Baro was 16.14

Enjoy fellas!

P.S. I did this all with about 50lbs of tools in the trunk, my 35lb roadside safety kit, full leather interior and the spare with the jack and stuff. I had two socket sets a box wrench set, extra bolts ect... I was the only person with a "trunk" so I carried the tools. I think with a proper tune this car could be into the high 13's with a good launch.

Thanks for looking guys!

 

[bullettdsm]

There you go. Got that 60' down and trap up. Now you're talking. A little more seat time (and a little less tool weight ) and you'll be touching on 13's

[cs82685]

Congrats on getting the times down, like Mark said, more seat time and less weight and you'll be seeing 13's without adding more power. How much boost are you running?

 

[link16]

What is "More seat time?" Keep the tires on the ground? Sorry, I am still new to racing.

Don't EVER EVER EVER EVER EVER rely on a narrowband for an accurate AFR.

That date has long past, I have an innovate LC-1 wideband. I also am making it a note to go get a nice dyno tune soon after christmas.

This is an updating thread so I don't clutter the forums with my petty RS-T.

8psi.

Sorry for the double post, I am a retard...

Practice.

Good to hear those times are only on 8psi too.

You want to straddle the peak power curve for the best acceleration/torque at the wheels. Each gear will have a slightly different shift point. Generally, the higher gear you shift into, the lower the shift point since the gears are spaced closer and the rpm won't drop as much. You need a dyno graph and to know all of your gear ratios to find out the best shift point for each gear. There are many rules of thumb, but this is how to find the exact shift point, not just theory.

Horsepower vs torque and
The Optimal Shift Point

Nice improvement by the way

 

[link16]

Practice.

I just want to put it out, but these times are on 8psi on the lowered compression pistons I have the Wiseco 8.8:1, so I feel special.

I will get to tuning later in the winter as I won't be racing anything anytime soon. I am saving for suspension upgrades now

 

[93EclipseGSX]

heh crazy... i was 13.2 @ 99... you over 100

anyways guy you gotta work on those launches!! i know they arent easy but even with 2WD you should be able to pull 2.2 60". and that would get you high 13's or low 14's. GL man, keep practicing.
