I did not even get into the elevens. :(

I've had multiple changes since I last went out: New exhaust (ARK Grip), slightly richer Uprev tune, changed boost controller switch (Blitz controller breaks after 6 mos and doesn't go into boost mode. Scrapyard junk, although it boosted properly.)

Multiple passes with a new HKS EVC-S boost controller proved it to be non-functioning or something. Jimmy was frustrated enough with it at The Shop that he turned it off until we got input from someone at HKS (or a distributor) who understands this particular unit. When you turn it off it runs on waste gate spring pressure alone. That was not enough boost. About 8 lbs.

That was my best run: 12.05 @ 117mph.

Any time I tried to run with the boost controller it would boost HARD to either spin the tires, and/or run into the HKS 'safe' Drop Mode and drop down to about 5 lbs of boost for the duration of 2nd gear--then it would come back in hard, but I'm halfway down the track. It still ran 117 when it came back on. Another 12.0 bucking and jerking.

A simple inexpensive manual boost controller would have been MUCH more trouble free. Sigh.

Anyway, that's the close of my season. We'll diagnose the EVC-S and either get it right (with input) or scrap it. The directions are complex and translated Japanese. Maybe there is an incorrect hookup. I dunno.

I did get an aborted pass with a 1.80" 60" time, so it was working hard.

Drag racing is hard. My experiences show me there are usually more disappointments than successes, but I'm persistent. After I regain my dismay, we figure out how to not make the same mistakes. And figure out new ones. :bowrofl:

I know how you feel man. I've been trying to beat my stock time all year with no luck :icon17:

I need to get my car tuned ASAP!!!!
I'm interested to see what you put down on jacks dyno as well:D

Here on the island of Guam I ran last friday. 370Z 7AT Stillen gen 3 intakes, Motordyne intake manifold, ARK exhaust, UPREV tune, Berk HFC's. I ran a 13.3. The track here sucks cause its a coral pavement so no traction at all, plus it is 85 degrees all year at night. I cant wait to get back to the states in the cold and run the car.

Looks like there's not much going on here at this time. Nothing exotic, maybe I'll do an after market exhaust this time.
I'm thinking that I might be able to be in the 12.1 to 12.4 range.
Looking forward for some fun. As always, I would welcome 350z/370z racers to join me. MD, N.J. N.Y. drag strips. Keep you posted.

BLACK or WHITE color....:)
I feel your pain, andre.
I decided against the cts-v and stick with the nissan family. so i am buying my new car after the turn of the year and yes ima race the hell out of it. Also dont forget you owe ray and I a night @ the strip club hahaha!!

As I'm giving thought to a 370z, you come out with a GT-r.
I posted somewhere here about the strip club.
I wasn't happy buying/bringing the wrong front wheels, not able to shift into 2nd, not launching the right way for slicks, front wide radials, & ply slicks ='d hairy rides, all over the place. Not in the best mood, so I'll take the blame, & owe both of you, dinner & strip club.
At least you made a decision. I don't know what I'm doing:confused:
My road test of the 370 didn't go well. Handling, everything was great, I just didn't feel the power at all. The rpm went to redline quick & easily, just no punch/flat. I know 370's are quicker, so it must be me, not used to that feel??? You know I'm long winded at posting.
I'm near Baltimore. Tomorrow I'm going to see my Z & discuss LS swap, or rewiring my car & moding it more, or getting a 370z & going after your record:) I'm so confused:eek:
If I had a car, plans for a Florida trip would be on my mind.
Then again, we don't have a car to race. If I build my LS, I'll race your GT-R next year:)

I ran a 14.322 this past Friday out here in Phoenix, AZ. Don't know if it had much to do with the track conditions being cold but I was definitely disappointed with my time. I have K&N Drop Ins, Mishimoto MAF Tubes and AAM Short tails. My tires are the base Yokohama Advans... reaction time on that run was .7. Anyone have any advice for me? I can't imagine why I would be a second slower than what the car is supposed to run bone stock. It was my first time at the track but I don't feel like I'm that bad of a driver...

The more power you to start to add really starts to show the weakness of the tire.
You need 2.0 or lower 60's and no lift shifts and you will get in the low 13's to high 12's

Fairladyz916 12-05-2011 03:23 AM
Beast mode u hit 14.3 at 102 it is ur takeoff that is suffering work on that cause ur top end is there

R/T means nothing, unless you are actually racing.

60' is ALMOST everything.

And if your 60' is good, then maybe your shifting is slow.

I would say it is a combination of factors. My car stock was running a 15.3 for my best time. I have a few things to factor in though. Biggest thing being my lack of experience at the drag strip. Also the track is at roughly 3700 feet above sea level which plays a huge role. I think with more practice you will see better times.

Z eliminator 01-10-2012 07:24 AM
Before I put the SC on the car for this year im going to try to lower the N/A bar into the 12.19's I will have the GTM built 7 AT with a quiafe in the diff. The car will loose another 40 lbs bring it down to 3320 lbs with me in it. Present 60 ft time 1.835.with the GTM converter.
The torque converter has been sent to Pro tourque to raise the stall on the GTM converter to 3500rpm from 1800 rpm.
Time will tell what ti will run with a preped track in april.

tranceformer 01-13-2012 11:37 PM
It was a good night for racing. I made 3 passes tonight with the new parts on the car, the track was pretty well prepped. My 60ft times in order: 1.94; 1.89; 1.88 seconds.

Final pass of the night:
12.876 @ 109.40 mph
1.888 ft

mods:
Stillen oil cooler
JWT flywheel
4.08 gears
SPL solid diff bushings
SPC rear camber arms
HPS post MAF tubes
DBA 2pc front rotors
FI longtube headers
Motordyne XYZ catted pipe (y-pipe w/ cat)
Stillen crank pulley
Uprev tune

The car still has more in it, just need to get used to revving it out to 8000 rpm (shortshifted 1st and 2nd gear). Also had a little wheelhop @the top of 1st and shifting into 2nd gear. :icon14:

Thanks bro. Just like you, I set one really good time (with minimal mods) and have been struggling to beat it even after installing more mods. It took a few nights of practice to figure out how to consistently get the car off the line quickly with the new gears + tires + alignment.

The car is running good with all the new parts, I just need to utilize the 8k rev limit and shift a bit quicker to get the last few tenths out of this setup. I think on a good day with the proper driving I can get 12.5 @ 110 mph. I'd be happy with that, especially since from the exterior the car looks and almost sounds STOCK. :icon17:

Yeah I've just been having one situational problem after another every time I go. I'm probably going to go just one more time in the spring to a private track rental with some of the guys here. Steve is planning to get some DR's for his 5.0 that he said I can use for a couple runs. Hopefully I'll be able to beat my stock street tire time as well. Hoping I get into the 12's again.

If you shift at 7200 to 7400 you will go faster, The ECU kills the moter past 7600 rpm.

Not if the rev limiter is moved higher and the car is tuned to make more power past 7500 rpms.

Isn't this classic. I've been through this so many times. We'd LIKE to think the quicker ET's will just show up at the booth, but, it rarely happens that way. In fact..... :confused:

Great work for such a sleeper. Really fast.

It's street tires or nothing for me.

Mine made power on the dyno up to 8k. I need to make some more passes to see what works.

I found out that my tach is off by ~200 RPM. The tach is +200 RPM from actual. Example: tach reads 7200 RPM, actual is 7000 RPM. :shakes head:

"practice makes perfect"

"if it was easy everyone would do it"

As I said earlier the biggest hurdle was figuring out the sweet spot for launching the new setup. That probably took me 20 passes to figure it out. But even with good launches it didn't feel right with the 4.08's - felt like I was shifting too early. And after the dyno tune session... it turns out the tach was off and I was shifting too early!

Good, consistent times will come soon enough. I just need some more passes to figure out how to get it done. :cool:

Thanks! :tup:

I just went out to the car and put black electrical tape over the HPS sticker on the post MAF tubes. Might even change the T-bolt clamps to something less conspicuous (as someone suggested to me). Still got the stock muffler and midpipe on there too. ;)

Z eliminator 01-18-2012 08:32 AM
My tack is off by 200 rpm as well. I have the limiter set at 8100 . I have hit the limiter at 8300 rpm on the tack.
after 7600 rpm i feel that it just does not pull as hard. i usally try to shift at 7800 .
i see that your getting closer to my 12.42.
before i got SC , i will be running the fulley built GTM tranney with a quaife diff.

I'm looking forward to my first run at the track. I'm sure once I nail down the launch.. if I do anything less than 13.5 I will be very disappointed in mysef.

Don't worry too much about ET your first few times out. Just have fun and work on your 60', the rest will come with experience. :tup:

tranceformer 01-28-2012 03:06 AM
Made some (4 to be exact) passes tonight, beat my previous best from 2 weeks ago despite tonight's warmer, more humid weather.

previous best:
12.876 @ 109.40 mph
1.888 60ft
DA = 120 ft

tonight:
12.860 @ 109.09 mph
1.921 60ft
DA = 988 ft

With better 60' time, 12.7's. What h.p are you producing with the tune? I also see you are using a different exhaust. Is it better/different than Jason's. You also added headers? I'm still at LS or 370z:confused:

i was pulling off high 1.8x 60ft launches a few weeks ago.

270 rwhp on a mustang dyno (the tuner said 30 to 40hp above stock)
i swapped out the y-pipe with an aftermarket one
yes i added longtube headers
just flip a coin

chuckd05 01-30-2012 12:56 PM
Nice time. Still at it I love that.

It seems the hurdle is 60 ft...

Why not shoot a small shot of n2o go look at what the vq35de does with nitrous.

They are pulling some insanely good times with relatively small shots. Even maybe a 75 straight outta the hole. Should get you to 12.1-3 I'd imagine rather easily.
