Conditions weren't exactly optimal tonight with <30 barometric pressure, high humidity, and 93 degrees, but still got some PBs! Just posting up times tonight will upload pics of the car and slips tomorrow, but here's a rundown:

1st run was on street tires and full exhaust:

'60: 2.152
1/8: 8.825 @ 82.39
1/4: 13.567 @ 102.59

Next few runs were on slicks and pretty similar to this one:

'60: 1.841
1/8: 8.349 @ 83.18
1/4: 13.105 @ 102.84

I then unbolted my 2.5" axle dump and picked up about 1-2 mph traps. Best trap run:

'60: 1.997
1/8: 8.525 @ 84.08
1/4: 13.226 @ 104.15

Best ET:

'60: 1.857
1/8: 8.322 @ 83.80
1/4: 13.026 @ 103.91

I was hoping to break 12s, but it definately wasn't my night with the conditions the way they were. Hopefully I can get a cool/dry night sometime soon for some better times. My trap was definately down from that perfect 60 degree night last fall where I got the 105-106s.

 

nice times, I was expecting alittle more with the u-tec install do you think changes are required.

either why atleast your headed in the right direction

 

deff. has 12's in her.
I'm sure once you play around with that utec things will only get better.

 

did you launch at the same rpm for both the street tires and the slicks runs?

 

Nice runs. I was also wondering where you launched at. I think that you do have 12's as it sits.

 

Well the car feels way stronger on days with better atmospheric conditions. I was datalogging the whole time and my tune is spot on, I just need a better track day to see the 106 traps and hopefully high 12s. That run last year was in 60 degree weather with 0 humidity and high barometic pressure... last night was basically the opposite of the conditions I need to see to get the most out of the car.

Honestly tonight would have probably been another one of those 14s @ 99-100 nights if it wasn't for the UTEC. The bolton/mevi 4th gens were running bests of high 15s in the low 90s last night.

On the other hand my buddy's cobalt runs better the hotter it gets... he pulled a best of 13.16@107.4 on street tires with a 2.17!!! Turbo cars FTW when it comes to depending on atmospheric conditions for good times...

I launched at around 3k on street tires, and started to hit the gas as I slipped the clutch, and let the clutch fully engage around 4k rpms then floored it. I shifted a little easy into 2nd then no lifted the rest of the track.

On slicks I was launching between 4 and 6k. My best 60 foots were at around 4500 rpm and letting the clutch out HARD but not hard enough to cause it to bog.

One of the guys last night took a crappy cell phone vid of one of my worse runs, if he sends it to me soon I'll get it uploaded on youtube or photobucket and link it up in the first post.

 

Badass times!!!

You have a 12 sec timeslip for sure if you get your 60ft in the 1.7 range.

 

I'm sure it's got a 12 second with the same '60 foot and better conditions! Maybe high/mid 12s with a 1.7.

 

I wanna see what it runs with a 1.7 60ft.

 

Nice runs. How much psi are you running in your slicks?

 

+1, I wanna know too.

 

around 15psi, have gone as low as 14psi but didn't get any better. I also run 50psi in my rear tires.

 

Nice times

 

good runs man! what PSI were you running in your street tires? -gotdamnit, i gotta get my car fixed...-

 

1.8 60' is SICK!! congrats!

 

+1 it is

 

I ran 25psi in my 1 run on street tires. I think I could get a 2.0 with about 22 psi and a little practice on the launch. It dead hooked and I'm sure I didn't push it as far as I could have.

Thanks man, 1.8s are definately a rush. I even pulled a high 1.8 with my GF in the car and she got pretty excited by it lol

I think I will need wider slicks to pull lower '60 foots. I was spinning all night, including on the 1.8 runs... the little 8.5" just don't quite cut it.

 

i would love to send that video to you, but it wont let me because it says the file exceeds the proper size or something. too large of a file for my cell phone....

 

Try lowering the pressure quite a bit more. Try them at around 10psi, and I bet you won't spin.

 

I may try as low as 12 psi, but according to manufacturer suggestions, I'm already running lower than the reccomended minimum of 16psi.

 

Congrats on the new times! What kind/size street tires are you running? You seem to be launching a lot higher than I was..

FWIW, I planned on running the same 22 psi in my tires next time, hopefully it works out for the both of us!

 

yo dude where did you get the AE lip kit for the rear bumper? your whips sick by the way.

 

The Honda guys run as low as 6psi on the 24.5 slicks. It seems to work for them.

 

245/45/18 Potenza re040s that came stock on the 350z track wheels.

I don't have any lip kit, thanks for the props

 

ohhhh...those are pretty nice!

 

Yeah I've pulled bottom 2.0s on them at the local 1/8th mile with amazing track prep. Next set on the front is going to be 255/35 general exclaim UHPs or dunlop star specs if I want to spend twice as much.

 

fail!

Does your phone have a USB port or a card slot?

 

I recommend re01r's or the advan a049 (I think) but they are pretty expensive, though tirerack was having a great deal on the re01r's..

 

Well I've had great experience with the exclaim UHPs pulling 2.0/2.1 '60s in my spec V with 225/45/17s (for half the price of most other summer tires) and the dunlop star specs are said to be the next KDW-2 for dry traction and get considerably better reviews and better price than the re01rs.

 

i idol you...lol.. damn i need to get headers soon....

 

I might have to check out those exclaims...they sound good..

 

Dunlop Direzza Star Specs are the tires of choice right now. They are winning every comparison they're put in. They win dry traction and try track time comparisons by a little bit, and absolutely demolish every other tire in their class in the wet. And they're the cheapest in their class by a long shot. I just bought a set

That said, my best street tire 60' times ever came on some 4 or 5 year old all season H rated tires and I've never noticed any significant improvement in 60' times from one street tire to another, from old *** all seasons to high end wide Z rated tires, over the course of about 500 track passes (probably 300 of which were on street tires).


OP: Awesome times man.

 

Congrads on the times! If it werent so hot that would have definitely been 12's. I was going to go to the track again tomorrow but its just to hot..

 

Great times!

 

hit the 1/8th mile tonight and had almost identical conditions, even had some rain. Best was a 8.4@83.5. Going to wait for either new mods, a really cool night, or maxus before I hit the track again!

 

Just spent a little time messing with dragtimes DA calculator and correction and my runs from last year on 12/06/2008 were -415 feet DA... So those UNTUNED 105 mph traps N/A make sense!

My runs from 5/09/2009 (the ones in this thread) were 1800-2400DA depending on the time of the night, and with their corrections my 13.0@104 would have been high 12.6s in the high 106-low 107 trap range.

Hopefully I can get a nice day sometime before fall (doubtful) but I guess I can look forward to some quicker times when the weather gets better closer to fall/winter!

 

what size slicks are u running and on what rims?

 

24.5x8x15 MT ET Drags on 4th gen sawblades. I had to shave my calipers for them to fit.

 

Well I personally went from 2.2-2.3 '60s on 225/50/17 goodyears spinning halfway through 2nd to 2.0-2.1s on 245/45/18 potenzas and able to floor it in 1st. I'm sure the width/height made the biggest difference over compound, though.

 

Congrats nicely done...
