Hey guys,

Yesterday I went to Summit Motorsports Park out in Norwalk, Ohio with my friend who has a modded AWD Trailblazer SS. Despite the long wait, I had a lot of fun, and ended up running some decent times.

Here are some pics:

The TBSS has an intake, an ECU tune, and a TCU tune. He took out the headlight because it supposedly takes off .2 of a second at the track. Needless to say, he was running faster tonight than he usually does.

Here is an old video at another track:

His best time of the night was like a 14.16@98.349, and his worst was 14.299@97.76. I want him to put the headlight back in becasue with a better launch I'll hang with him down low and start to creep past at higher speeds.






We also found a C63 AMG which ran a 12.1@116 on it's first pass. I'm not sure how it fared on the other runs, but he said he was shooting for 11's. It had drag radials.











As for my races, I only had three, so I didn't really have much time to experiment, but here are the times:


Run-1 (1100 tq brake, hit the limiter at the end of the track)

MPH 76.28
1000 12.101
1/4 14.400

Here is a pic of the slip for the last run. I went against an intake, exhaust 6 speed V6 Accord that moved out very well.





Overall, I am pleased with the runs, and I feel that the only thing that could've done differently is try a higher launch point. I started at 1100, 1200, and 1800 for the runs, and 1800 netted the best time and ET. Then again, I hit the limiter pretty bad in one of the other runs, so who knows. Track prep was pretty good, so I didn't lose any traction coming off the line. Next time I'll try a launch at 2500 to see what happens. Maybe with some more revs it has a 14.3 or a high 14.2 in it.

Let me know what you think.


Here is my best time of the night corrected (I used a calculator on SmokEmUp.com).

UnCorrected ET:
14.400 (sec) @ 99.04 (MPH)

Corrected ET to Sea Level:
14.284 (sec) @ 99.858 (MPH)

 

Those are very good times your mods. Congrats

 

very nice times... i want to go back to the track soon too. =)

 

Thank you! I'm going back this Friday to try out some new launch techniques.

Thank you! I had a lot of fun, and now I'm addicted. I've had poor luck with many of the other tracks I've been to (long wait, rained out, ****ty track), so I'm excited that I found one that relatively close by and fun.

 

Damn, nice times.. I wish I could run in CT or anywhere east coast lol

 

This was actually in Ohio, but the strip is pretty good. A lot closer to east coast air than CA/AZ.

 

Very nice. It's good to see another 5AT posting 99mph traps with minimal mods as it gives me some credibility with regards to my 5AT's performance. It's also good to see another "slow" 03 sedan posting great times and mphs. you need to up that launch rpm into the 2200-2400rpm range. You'll definitely get into the mid to low 2.1 60 foot range. Our cars perform identical when comparing your 14.40 slip to one of my lower 14.4 slips. They're spot on for ET and MPH, increment by increment.

 

All of the recent threads about 15 second passes made me doubt the car a little bit. This makes me think that the slower running G35's can be attributed to performance robbing mods, such as 20 inch wheels, or driver error. I didn't really do anything special when I ran, and I think it would be easy for anyone to replicate my times.

I too feel that with a higher launch I'll be able to get a lower 60 foot. Weather permitting, I will be at the track again on Friday to try out the higher launch rpm. Hopefully the track conditions will be favorable.

It's interesting to note that compared to the Accord, and my friend's TBSS, my 1/8th mile trap was almost 2+ mph slower (76.28 vs. 78.34), yet by the end of the strip I out trapped both. I suppose the longer third gear makes up for slower trap half way down the track.

Either way, I'll work on getting the times down.

EDIT: Have you ever noticed a power loss, etc. from disconnecting the battery? I read some thread about it, and ever since then I've been freaked out to do it. I want to keep as many variables as possible the same for Friday, but I also want to install my system!

 

Bingo. Weather too.

I think it's a VQ thing. My G is the same way as was my modded 96 Maxima (14.3s@100mph). Both cars tend to see a gain of around 22mph in the last 1/8 mile. Simply put, the VQ has some legs when it comes to topend acceleration.

It's been my experience with the VQ cars that there is some reduced performance just after resetting the ECU and it makes sense. When you reset the ECU, the ECU will default to a really rich fuel table and retarded timing because it needs to validate conditions such as fuel grade, density altitude, etc. If the reset ECU started off running super efficient (ie fairly lean, advanced timing), it could potentially wreck the motor due to an overly lean condition. I've found it usually takes about 2 to 3 days of driving to get the car back to where it was.

The things I notice right after a reset is boggy performance, especially at low to medium throttle. WOT doesn't seem to be as affected.

 

Oops, I must've disconnected the thing about 10 times today when I was doing the install.

Either way, I'll log some miles later in the week to help the ECU relearn things. I hope it doesn't make a difference, and I don't think it will.

 

I thought I read around here that holding the brake and throttle actually slows down the start because the ECU cuts power when both are applied at the same time. (???)

BTW, looks like you beat #19 on the list. You should post your time on this thread:
