My attention was drawn to the numbers

 

They may have pulled the Skyline GTR deal with us. Japan does not allow. More than 280 hp on a car. They say th GTR has 280 but more like 320hp for real. Also they have a luxury tax on V8's.
A standard day for rating hp is 15 degrees centigrade or 59 F at sea level. The colder it gets the more hp you will have I have access to a dyno and will post numbers when I get mine. Think wider gripper tires will help the numbers. I'm just wondering what kind of pressure he clutch/pressure plate set up is in the stock model? The stock 300z NA only had about 1200 lbs of clamping force.

 

Here is some info that I have concerning G-Tech 1/4 mile accuracy and the trap speed issues.

After extensive test runs in my Firehawk comparing the timed results from the GTech Meter to actual timeslips from Moroso I have found the GTech to be extremely consistant. However, a consistant correction needs to be made to compare the times recorded with actual time slips. This correction is -0.2 seconds and -2.2 MPH. This is due to the way it begins to time a car the instant it starts to accelerate as opposed to the dragstrip timing where the timing begins after you have traveled 8 - 12 inches. Also the MPH from the GTech is higher because it measures your speed exactly at 1/4 mile while at the track you speed is calculated by timing your last 150 feet before the finish . Yes, this is why it is important to "NOT LET UP" in till you are past the finishline.

In short: I have found the GTech times consistantly higher by 0.2 seconds and the MPH higher by 2.2 MPH

 

I'm have no experience racing, so I'm willing to be educated here. I read at Brembo's web site that they are designed to be especially lightweight to reduce "unsprung weight", thus improve driving performance. I have also never heard anyone say that the LSD is anything but desirable. Did "slushy visous (viscous?)coupling" refer the LSD or were you talking about the AT (which most people who have followed this thread this far probably wouldn't have)?

Please tell me what you know about these parts holding you back.

 

Based on weight, hp, gearing, other cars, etc...I don't think they underrated this car any. It is putting down close to 250 to wheels stock on good gas...it should be able to pull 13's all day long. I think these times are more in line with what I was anticipating all along. I think when people break their Z's in, figure out the optimum way to launch this car, throw some slicks on it, etc...we will be seeing consistent times in the 13.5-7 range...not far-fetched at all. It's a fast car.

Raceboy, thanks for the info...keep up the quality contributions.

 

Wrong, so wrong, yet sooo funny

 

???

wtf is this.

 

Read the whole thread. Actually, it's a little more difficult because this in-joke started in another thread where raceboy warned that he was going to post these numbers, but it was quoted in this thread, someone said "if you beat 13.8secs Ill eat my cats". Things went rapidly downhill from there.

 

yo raceboy..when ur engine ish broken in..take it to da track and tell us what u gotz aite!

OK, raceboy, you might laugh at me here, but I really wanta know. It would be really cool if you could do a comparison run or two with the VDC switch on. It also ought to be educational for us all, including you.

I mean, isn't the whole idea of VDC/TCS to eliminate loss of traction? And isn't loss of traction (wheel spins, axle hops) a major cause of lower times?

Next time you run tests, please grit your teeth and flip that switch and let us know.

Thanks!

 

I think that TCS/VDC will make it slower b/c it cuts power for stability, although i could be wrong.

I would be very interested in you did a comparison between shifting at redline and shifting at say 6k or 6.2k.

 

I know nothing about this subject, but want to learn.

Some of the guys at a Cobra Board are using a Tazzo VPC unit. Would you please go to www.tazzo.com and give it a look. We would value your opinion.

Hell, the more choices the better.

 

raceboy! Thanks for the great post.



I WANT MY Z!

...JUST OVER A WEEK TO GO!!!!!!!!!!!

 

Thanks for the info. I like the fact that the tazzo does not need calibrating each time you go to use it. I was planning on putting a G-tech in the empty nav hole, with and S-afc and some other choice stuff.
Now it looks like I will get that Tazzo unit instead.

Steve

 

Good idea about making the nav hole useful. I might have to look into that. IS there any holes for wires in there are will you be customizing it?

 

Looks pretty cool. Given that choice now, I would get the Tazzo. I like the fact that it doesn't have to be level. That makes life a hell of a lot easier than the Gtech.

 

I will do all my own wiring. I am pretty handy with soldering irons and crimpers. My only problem lies in the depth. I am not sure how deep the empty space is, and how much room there is behind the inside blank panel. Hopefully there will be a couple of inches hidden back there.

There was someone, (Nizl?, hmm dont remeber for sure) that wanted to put there whole stereo head unit in the nav area, so he could close the door and everything. If there is enough room for that then there will definitely be enough room for everything i want to put there.

Here is the list of stuff i need to find space for(and planned spot as of right now):
1. Tazzo VPC, THX shoalhaven (nav area)
2. Boost gauge (piller pod or center to replace voltage gauge)
3. turbo timer, do not feel like replacing a DUAL BB turbo every six months(nav area)
4. Air/Fuel meter, round autometer type not 1/4 din (nav area or pillar)
5. fuel pressure gauge, maybe 2, 1 for normal tank fuel the other for alcohol/water mix for Water Injection Intercooler (nav area)
6. replace stock oil pressure to match boost in center area
7. Electronic boost controller, not sure which brand yet (nav area)
8. Fuel computer, but maybe neither 7 or 8, maybe just DFI (nav area)
9. Timing **** from ignition, will require aftermarket ignition probably (No F&*kin idea)


Damn thats a lot of crap. Im gonna have to start robbin banks or somethin to get all the money for this shiY.

 

With all this 1/4 mile nonsense, I figured I should post a link about some hardware for *real* racing. (I'm joking!!)

But seriously, check out this unit:
http://www.extremegeez.com/

I'd love to take that to the track with me next time I'm out there. There is also another unit I've read about that is similar to the G-Tech (which I do own), but is much more accurate, and will even account for things like wind resistance and suspension compression. (Which is an important factor when using accelerometers.)
