OK, I finally got to the track today. I think it is the second day of test and tune for the year. So many people have been bugging me about it. It was a last minute kind of deal and I was really not prepared to do it but what the heck! The guy at the tech line gave me grief about my battery relocation again, but still allowed me to run.

I have only tracked it once before and made one pass in my life so the results were kind of disappointing.

60' 2.403s
1/4 mile 14.115 @ 105.55 mph

Two things went wrong:
1. I started at low rpm (didn't want to burn out the clutch and run 18.6 again!) So no launch with boost at the start.

2. When I switch from 1st to second (and I still do this) the rpms drop to 3000 rpm.

Another time I went I got LBTA and got all messed up:

60' 4.2s (Ughh!!)
1/4 16.515 @ 107.04 mph (double ughhh!)

I got all flustered when the red light came on and started backing up (how dumb is that?), then I was supposed to go, my tires just roasted and again 1st to second shift was bad!

If I could hook up and learn to shift the damn thing, it should be in the low 13s, judging by the mph at the end ... am I wrong about this - could be, cos I don't fully understand it all. I need a LOT of practice!

I decided to let one of the PFI guys try the car, he wasn't used to it, but managed to get

run 1:

60' 2.566
1/4 13.945 @ 103.75 mph
(some tire roast and he missed 4th gear)

run 2:

60' 2.349
1/4 13.832 @ 108 mph

Kev and some others know how badly I shift! Certainly, a differential would help and some slicks as well as some lighter wheels, these 17" 2002 Maxima wheels look nice but are heavy!

If you look at it another way, I took 4.5 seconds off my previous ET! But either way, I SUCK!

Most of you will be like !!

keep plugging dude...good things will happen....

that 108 trap is at altitude right????

108mph is nothing to be laughed at

congrats!!

any good races there against the other people who are like wtf? those always make me smile

Even if you did mess up that bad, 108mph is still up there and I dont think thats anywere near what your car is capable of running. Just keep practicing (obviously) if you atleast get those shifts lightning fast you'll knock quite a bit off that that. A 2.4 60' is quite a bit of spin, as you said slicks are a must with the power you turbo'd guys are pumping out. You should be well into the 12's with the power your pushin, as you just figured out though all the power in the world doesnt mean a thing if you cant get it to hook up.
Good luck, im sure you'll see the 12's no doubth about it.

hey man that aint that bad especially the 108 trap, i bet it surprised the hell outta some people. think of this way you can only get better man, now i can't wait till i get down there but it probably won't be till may, when im done finals.

Just work on that launch, and your shifting. You should reach 12's with that kind of trap speed.

JAY25

iTrader: (38)

Did you install that quaife like you said you were?

also your trapping @ 108MPH, I am trapping 104's you should be in the low 13's and 12's once you get the launch down and get the 60's to 2.2? or below you ll be loving it then. Great job in any case taking it to the track. Car is very fast.

Good thing you didn't miss 3rd... again... and again.


j/k! Practice, practice, practice. You'll get better! 108 is

I am rarely in the country nowadays. In fact I leave again tomorrow for 2 weeks ... no time to race or install Quaife. Life sucks!

Most people look at the ETs and I did not perform very well but looking at the mph, it wasn't so bad. I was the only Maxima at the track. There were probably 3 Nissans in total, one was a 350Z, the other I didn't see myself but was told a Sentra. 350Z ran 15.7.

It is certainly addictive! I am not sure I want this kind of addiction. I know for sure I will break stuff! There were a number of cars that broke on the track, fortunately, only one spilt oil. Also, the closer you get to 10s, the more you have to spend and it is more exponential than linear. Also, the waiting sucks. It was an hour between runs!

My EGTs were surprising low for the most part at 760C. The day was hot with the sun, the air temp was OK - 78F (warm compared to recent weather).

I have videos of some of the runs ... or rather a friend does. I'll have to convert to mpeg and post them when I get back.

Thanks for the encouragement and not laughing at me! I knew I would not do well, but I guess I folded to peer pressure. Props to turbomax, who has held out for so long! He's a good guy, who doesn't give a crap what people think .. and I know his **** is fast! ... or was before he blew up!

I am getting greedy though ... wonder what a small shot of the ol' laughing gas will do? .. without injector upgrades, it'll just blow the motor! With injectors and all the other stuff? ... hmm!

You think you have traction problems now?

Dave B

108mph is pretty impressive and judging from your lack of experience, poor shifting skills, heavy 17s, and slow 60', you're car probably could pull 110-112mph quite easily and probably faster on a cold night. Those 2k+ wheels look amazing on a 4th gen, but damn do they suck out the power. They sucked out a SOLID .4 and 3mph from one the Maximas in the Kansas City group. The problem is their heavy weight and the lack of control once they're spinning. People seem to believe heavy wheels are easier to control off the line which is BS. When you put a heavier object in motion, it takes more energy to slow it down (ie harder to modulate the spin).

Auuugh...this coming from someone who NEVER goes?

Or do you have something to tell us?

Y2KevSE

iTrader: (13)

I don't need to go to the track since I can calculate my track time:

f(x) = sqrt( 4x^y * [Magazine time] - [# of rice mods on car] + ln z )'

I dont think it is possible to have a negative time keving.

Even worse, in his case, that mathematical function returns an imaginary number.

Don't forget guys Nigel is at like 5800 feet. 108 @ 5800 is like 113 @ 1000.

Canuck

Hey Nigel what was the pressure at the track on Sunday?

I know sometimes a low pressure day makes it seem like the track is at 8000ft

Bluebird

iTrader: (4)

I could easily be wrong, but I thought altitude doesn't affect boosted cars, just NA cars?

Blu

iTrader: (63)

Not as much but it does affect it quite significantly. I believe his uncorrected dyno was only 350 give or take whp so hes losing about 70whp from what he would make if he was at sea level

turbo97SE

iTrader: (3)

The temp was about 78F, absolute pressure was 23.38 dunno if that is high or low! As far as altitude goes, it does affect turbo cars but not quite as much as NA. I have heard that turbo cars at sea-level boost quicker (don't know if this is true or not) No one seems to like racing in CO ... probably cos they can't make the numbers they do at sea-level and that includes turboed cars. ... or it could be that everyone hates CO!

With regard to wet kit, if I ever did one it would be wet. Right now I have a dry nos kit #5124???. Yeah I hear you, big traction problems! What I am more worried about is breaking axles, tranny etc etc.

Actually, the formula is

f(x) = sqrt( 4x^y * [Magazine time]^2 - [# of rice mods on car]^2 + ln z )'

For you, I guess you are travelling back in time (like someone else mentioned -ve times)! Kevin's Time Machine! Just set the Blitz controller and go! ... don't forget the whales!

gtr_rider

iTrader: (50)

HitManSE

iTrader: (1)

But you guys still lost me on that formula...

turbo97SE

iTrader: (3)

Actually, you are thinking too hard. Let's simplfy the forumla by letting x, y and z approach infinity. Now take into consideration the number of rice mods on Kev's car (HUGE > infinity), therefore ( 4x^y * [Magazine time]^2 - [# of rice mods on car]^2 + ln z )is always negative. Now do ya get it? . That's how I got an A in mathematics! Actually, the answer is in the form of a complex number since the sqrt of a negative is complex! Bah too difficult to explain!

That's a car that sucks ...

... well it blows ...

... hmmm actually it does both, the turbo sucks in air and blows it into the cylinders

Craig Mack

Nigel: Why do your RPM's drop to 3000 when you shift from 1-2? Reason I ask is, becuase mine do too sometimes. It's usually a little higher then that, but still. Are we just bad shifters? When I go WOT I try to shift as hard as I can. I hope it's just our n0ob driving and not a mechanical thing.

HitManSE

iTrader: (1)

...and that is why I stick to simple mathematics. Too difficult to explain is probably right, ill just take your word for it. Ive just never seen that formula be4. I know its a joke but just never seen it.

IceY2K1

iTrader: (3)

Hmmmn...I'm pretty sure if x=y=z=Infinity(Inf for short) and

f(x) = sqrt( 4x^y * [Magazine time] - [# of rice mods on car] + ln z)
then
f(Inf)= sqrt( 4(Inf)^(Inf) * [Magazine time] - [# of rice mods on car] + ln(Inf))
= sqrt(Inf*[Magazine time] - [Inf] + Inf)
= sqrt(Inf*[Magazine time]
= sqrt(Inf) since "Magazine time" is relatively small
= Inf

So f(Inf) = Inf, so it's neither negative nor complex.

UMD_MaxSE

iTrader: (1)

but it is an indeterminate form => go to the track

IceY2K1

iTrader: (3)

However, this is Kev we're talking about, so that's imaginary.
