I went to Capitol Raceway yesterday for their Sunday test and tune. My last time out with a K&N drop in on stock tires I ran a 13.77 @ 101.4 with a 2.052 60ft, and an 8.8 1/8 mile.

This time around I have the mods listed in my sig, and I have S03's but they are extremely bald, the tread wear indicators have been showing for like 3 weeks, figured Id go to the track and kill them.

I know, my 60ft's suck a$$, I was pulling consistent 2.0X 60ft's on stock tires, but yesterday I couldnt do it, here is what I ran:

1st run:
60ft: 2.169
1/8: 8.980 @ 80.76
1/4: 13.78 @ 104.19

2nd run: Tried to launch more aggresively, just spun to redline, let off for a split sec in 1st gear-wheelspin in 2nd
60ft: 2.184
1/8: 9.070 @ 80.07
1/4: 13.918 @ 103.03 --->This is the slowest my car has been ever, my slowest stock was a 13.86 @ 100 with a 2.08 60ft

3rd run: Slight slip at about 1800rpm's then nailed it in 1st so I wouldnt spin as much-crappy 60ft, my best 1.8 mile trap though
60ft: 2.167
1/8: 8.960 @ 81.97
1/4: 13.747 @ 103.37

So overall I am very happy with my traps, considering I dont even have headers. I know my e.t.s suffered because of my weak a$$ 60ft's. I have a pop-charger on the way to replace the AEM, and a crank pulley as well. I am ordering some new tires next week, then going back to the track to hit some 13.40's....I will let you guys know. WIth my pulley and some headers, I am confident I can run consistent 105 traps, maybe hit 106, that would put me in E46 M3 territory. What do you guys think??

 

Congrats! I have trapped 104 also but I couldn't get better than 13.9. Here is my timeslips.

 

Here is another.

 

Alberto, if you had slicks I bet you would be low 13's easily maybe even 12's.

 

Nice times! Those mods help in the top end. I need traction too!

 

what rpm are you shifting at in each gear?

 

I am confused. You shouldn't be trapping so high and getting good ETs with your 60 foot times. Are your slips altitude/temp corrected? I am not calling BS, if you are getting those, uncorrected, your car is a fluke as far as being really well balanced, etc, very high output, I'd love to see a dyno.

 

Rob, if you are talking to me those times are from San Antonio Raceway so I am assuming those numbers are actual. I was racing my friend in his 350Z. The only difference between our Z's is his is stock and I have a cat back exhaust.

 

If your talking to me then...these are the times right off the slips from the track, they are not corrected. As far as dyno numbers go, I dont want to start a huge debate, but....I dynoed with my current set-up and only put down 3 more hp than what I did with only a K&N....the shop told me to throw away the plenum it was junk, etc etc. I could get into this more if you guys want. Before swapping back to the stock plenum I wanted to run it and see what my traps looked like.

And for Acerxz--->my shift points are redline on the 1-2, 6500 on the 2-3 and about 6400 on the 3-4 shift. And I powershift when I race.

I am happy about the fact that I can run 13.7's now with almost a 2.2 60ft as opposed to needing a good 2.0 60ft to run a 13.7 when I was basically stock. It shows my car is making more power, but not on the dyno

 

So your making more power with the plenum right? Also, what kind of tires are you going to buy next?

 

LOL, no not really, I have come to the conclusion that the plenum is a POS. I didnt make any gains with it, no 8hp peak, no 15 hp at redline, nothing. Still deciding on tires, was looking at the BGF drag radials, but the 265 they come in might be too wide for the 8.5" wide wheel. I'm going to also be doing wheels alignment once I get my rear camber/toe rods, to help bring the rear camber back closer to spec. I prolly have -3 degrees, this is not helping my launch.

 

What are you talking about??? do you know ANYTHING about drag racing? He's trapping 104mph with mods...seems about right to me. Plus he ran about the same E.T. as he did stock with a worse 60' becuase of his increase in trap speed due to an increase in POWER.

 

Check this out...

K&N only = 240 whp 239 wft/lbs 72 degrees
All current mods= 243whp 245 wft/lbs 50 something degrees

My car embarassed me on the same dyno that made me proud to have a pretty strong almost stock Z. The shop chalked it up to two things in me not making more power peak and losing in some areas.

1. The praised the plenum for what it tries to do, but they said that the edge of the plenum is too sharp of an edge, as opposed to the curvy, smooth stock edges. They said it causes too much turbulance and made me lose power.

2. The AEM intake is too long to be effective...they said the JWT even though the filter is under the hood will give more throttle response with less loss of low end tq. As you probobly know some people have lost power with this intake.

I decided to leave the set-up the same and run so I could see what I trapped, next I will be going to the track with the pop-charger, pullies and new tires. After that, I'll put on the stock plenum and dyno my car again, and also run it again.

After seeing a 104mph trap, that dyno has to be BS, you dont gain 3mph trap speed with only 3 more whp. What are your thoughts?

 

I take it you have one of the early versions of the Crawford then since the new ones seem to be pretty smooth. I'll probably go with a Kinetix plenum when I buy one.

As for the intake, short-ram is the way to go. At speed where the slight increase you'll get in power from cooler air matters you will have it even with the JWT. I used to have a Maxima with the VQ30 and all the quickest N/A maxs including mine all had short ram intakes....those with CAIs were always slower.

 

Yeah I do have an early version of the plenum. I knew I should have waited....oh well, you live and you learn.

 

You can be a real a** when you want to be. I know plenty about drag racing, we'll leave it at that. I worked 80 hours last week, so pardon me if I missed his mods. I must have misread, I thought he had said stock.

 

Call me an @ss all you want...it's not my fault that you read it wrong.

 

I just noticed your sig. the s2k DOES have the best transmission out of any mass-produced production car. There is no doubt to that. What's wrong with that quote?

 

alberto: good times... can you explain your launching technique? did you change it from when you were cutting 2.0 60's ?

tia,
michael

 

First of all....it's mostly opinion. Second of all...how do you objectively determine what "the best" is??

The quote is still retarded in my opinion...
