My brain does not work in 1/8 mile times, so I converted the numbers to ¼ mile.

Your 1/4 Mile ET is 13.38 seconds computed from your vehicle 1/8th ET of 8.544 seconds.
Your 1/4 Mile MPH is 102.08 MPH computed from your vehicle 1/8th MPH of 82.32 MPH.

Excellent numbers but just out of curiosity are you running a power-adder?

Alberto, I am FI, its HKS SC. I am slow to shift 3 to 4, still trying to watch/listen the RPM's, I think on this run I actually bounced off the rev-limiter.
This was basically the 1st time with a real burn out with the DR's. Tail end is coming out during the burnout, trying to stay in a few more seconds, still chirping 2nd gear.
It seems to be running lean, at WOT.
this is at 2400ft elevation, I think the correction factor puts me at the around 13.1xx at 106...problem is there are no sea level tracks close by.

Running the stock hks pulley man? Seem alittle low to me, alot fo n/a guys with bolt ons run that.

 

+1 u should be running 11..... or 11ish up to 11.5 not more though depending on how hight the boost is.

 

the on going question....

davidv, HKS SC and tuned. Something is wrong, I guess. My numbers have always seemed low. I remember Ninja running a 12.9PB on this system, so that was my goal, and he did it on street tires! I appreciate you taking the time to convert the 1/8 to 1/4..i have that formula somewhere.

I have been trying to get back on the dyno, just the shop and my schedules seem not to mesh.

I go to redline every time...I, no longer, mis-shifts..which explained my low numbers before. I'm leaning towards "it was hot"...about 90 degrees.

I don't know about 11's...that would be reaching a lil bit. Thanks for the vote of confidence tho...

RESPECT

 

Its an interesting time slip. I can run 82 MPH, but not get anywhere close to 8.5 seconds. I think that the supercharger will kick butt in the second 660 feet (1/4) mile.

 

Nevermind what some people are saying. Some have given good info, but others aren't factoring the most important aspect of your run: LACR

Many people know how bad that track is, but no one will certainly know the reality of the horrific conditions of LACR until they do a run there.

PS. Using LACR's "correction formula" will only correct altitude. Although the altitude is bad enough, the formula is partly useless since traction & heavy wind is LACR's huge downfall.

.

 

LACR does seem to be a pretty horrible track. You do have very nice 60's though, and you did improve. You wouldve had a pretty good 1/4 time. Keep it up!
Your trap speed is not all that impressive. Im curious what kinda of power you are putting down as well.
And when silvernismo was talking about 11's, he meant your AFR. You could be in low 11's and it would still be a conservative tune. Atleast thats what he is trying to say. I would stick with the 10.5 myself, and have a good safe, conservative tune. As long as the timing isnt being pulled like crazy, your biggest gains in a tune dont come from you AFR. Timing is key!

 

nice launch....nice car...nice run

"oh snap, oh snap, oh snap"

 

Like your son said in the vid, Do a real burnout dude and launch that facker...

 

Those are good times for LACR no worries, you did fine.

I have a question though, is the Z a base? It looked like one wheel was spinning.

And whos the chick? lol

 

FI cars wont correct as low as NA...maybe 2 tenths or so for a car in the 13's thats FI....temps are more important than elevation for FI cars...heat soak sucks...70* is the correcting temp....normally above that expect to be a tenth or so slower for every 10* above 70*....general rule anyway

Edit....took the liberty of gathering some weather data for Palmdale on March 10 2007 from your slip.....pressure was around 30.03in, temps ranged from a low of 53* to a high of 77* avg temp was 66.....so kinda cool day....and the wind was a steady 7mph with resported sustained winds of 15mph and gusts as high as 18mph so that didnt help much

Get some dyno numbers cause I would guess 280whp-- maybe 290....but thats just me....I am probably wrong

 

When I run at SoCal tracks I tend to try to compare to other cars there, and what they are running more so than 1/4 times by people on this board. Our conditions suck, so watch other cars, and ask them what mods they have.
What did you dyno over base numbers? I would think your et would be 12's at a nice track with cooler temps...

 

drap660 - funny thing is I can't get as good a 60' when I do longer burnouts. Ya, my son...aka, my #1 fan.

97supratt - sorry bro' don't know the chic! lol
I have a performance model with OEM LSD...that burnout was with the brake fuse out, and the car stalled! Then I did a 1st gear to the line.

sergeEK - thanks for lookin up that info. The car dyno tuned to 335hp, but the AF's were different...I'll post the dyno sheet this weekend.

350zSteve - Thanks for the vote of confidence.

FYI - I'm thinkin' line locks to get the DR'z nice 'n sticky. I'll be back on the dyno to try figure out what is goin on with the AF's soon...

thank you all for your replies, any and all info is helpful...to one..and all. Also, thanks all on the props on the car...I like it too...lol

 

did any1 notice that 1.29 reaction time?? Guess, I was sleepin!

 

I know I could care less about peoples reaction time, unless they are braket racing. IMO, no need to get a good light, if its going to mess up your launch because you arent truely ready. It only matters when racing in competions.

 

I agree...just kinda funny. I guess its all competition on the track...whether you're trying to beat your PB or the guy next to you...
I notice that I get real competittive as I get to the light...

thanks for your post...
