I ran with stock 16" wheels, 32 psi, 1/4 tank of gas, stereo system (50 lbs) and it was around 80 degrees. Here are the times:

This is my first "true" time at the strip. I went back in Febuary but my clutch decided to die at the track with 99,700 miles on it. So I don't have any previous times to compare with. I actually ran 4 times but the first run I drove through the wet box and did not spin my tires. When I launched my tires just jumped around and spun. When I did get traction again I layed down an eye scorching 17.1.

The second run I ran redline in each gear and held 3rd gear through the traps. Run 3 I ran redline in 1st and 2nd gear and in 3rd gear I shifted at 6400 into 4th. The last run i did I shifted at redline in 1st gear, 6300 in 2nd gear, and I held 3rd gear again through the traps.

I'm happy with the consistency I got first time out. I am dissapointed with the times given the mods I have and that my max is a 5-speed. Modded 4th gen autos were running 15.2 and 15.3 last night. Toolrocks ran a best of 14.8 and he has a 95 5-spd intake/y-pipe. I feel that my max is .6 to .8 seconds of where it should be.

From the information I have provided you can draw your own conclusions. I know my max is faster with the VI installed. I don't think the midrange loss I am seeing with the VI is costing me that much time. This weekend I will check for codes and take a peek at my y-pipe. My y-pipe is three years old, rusted to he!! and has started to hiss under full throttle which it did not do before.

 

Did you make any runs with the VI off for comparison?

 

15.2 with those mods and a manual tranny? - it might just be the lack of experience maybe?

 

just a word of advice. try to compare your numbers aganist other maxes that run at that track. comparing numbers for other maxes in different parts of the country isnt a good idea.

No I did not get to run with the VI off. I was at the drag strip for 4 hours and the wait inbewteen runs was ridiculous. It seemed like every other run they had to shut the track down to clean something up. The next time I go, I will do that though.

You calling me slow? There's no doubt that I can improve my times by .2 to .3 seconds. However I still feel that my max should be performing better.

Yes I agree that comparing track times from different areas is comparing apples to oranges. The times I mentioned in my post were from Maximas running at the same track and time as myself.

 

Speedtrip you hit a bad night at Capitol. It seems like every time I go there the track gets more and more torn up, not to mention it was like 80+ degrees the entire night. Go to MIR (www.mirdrag.com) tomorrow if the weather holds up and see what happens. Im going to try to go.

 

I was disapointed when I went to the track after I swapped transmissions. I had stripped my interior out (Everything except for the driver seat) and the best I could do was 14.9 @ 92mph. I wasn't expecting to get a time like the blue, but I thought that my mph should have been higher (around 95 or 96mph). I know that different variables come into play, but at Carolina dragway the altitude is 370 ft., temp was about 75, and I had a 2.3 60ft. To me it should have been faster.
But now I know something is wrong, because my car now hesitates at WOT at @3800 RPM and then kicks back in. I checked the codes but nothing comes up other than the sensors that used to be on the auto. I think it might be my ign. coils.

 

The first place you have to start working on is your reaction time. You should be down to the .6-.8 consistently. Pros, are in the .3-.4 range. Over 1 second, and you KNOW you're getting spanked off the line. I also expected higher 1/4 mph. My bone stock 98' SE 5 spd ran traps in the 91's and low 92's. Maybe I'm just blessed to have a fast Maxima.

 

First off, r/t has no bearing on his ETs. He could sit at the line for 10 minutes and he'd still run the same time, the timer doesnt start until the car crosses the first laser line. Second, under a .5 is a red light anyway.

 

If this is your first time to the track racing, then all of this is a "write off" and a learning experience. The first time I went to the track with my Maxima (intake, y-pipe, muffler) and I was getting consistent 15.5-15.6@91mph with 2.4 60 foots. With the same mods and lots of pratice (~40 passes), I managed to get into the 14.8s@94mph with 2.2-2.3 60 foots. Seeing that it was 80 degrees out and you're engine was most likely heat soaked, you're going to be slower. I'm usually .2 and 1-2mph slower in 70+ degree weather. Your 60 foots are killing you, especially when they get into the high 2.3 range. If you are spinning into 2nd, it will make things even worse. Don't get so greedy off the line and try launching with a quick clutch slip at 2200rpms and experiment. You've got to shift quickly, almost like you hate the car.

The dyno plots of the VI show that you MUST take EVERY gear to redline to take full advantage of the VI. You've got to remember that the stock tach is off by a good 200-300rpms (reads high). As indicated by my tach, I'm shifting at 6600 1-2, 6300 2-3, and 6100 3-4 with my stock manifold. These shift points were multiplied out using gear ratio and my dyno. When I get my VI on, I will be shifting as close as possible without hitting the rev limiter (~6600-6700 indicated). Simply put, you're cutting yourself short shifting at any less than redline.

How fast was Toolrocks going MPH wise? How much more experience does he have over you?

It depends on what kind of tree he is using.

 

I was unaware that there were different kinds of trees but for conversational purposes, the track speedtrip was running at uses the more conventional tree which I was referring to.

 

I will try shifting at 6700/6800 next time. I have noticed that the rpm needle goes 200 to 300 rpm into the red zone on the tach without intervention from the rev limiter.

I can't remember toolrocks trap speed. I want to say low 93 mph for his 14.8 run.


Sin-
As to the kind of tree capital uses it is a Sportsman Tree. A .50 second reaction time would be a perfect light.

 

um pros in the .3-.4 um naw if anyone is .3 then you redlighted and .400 on a pro tree is perfect light so im assumeing they are runing sports tree where he was so yua want mid .5 is really good
