????????? my A## you dont, Ive had two turbo cars and had both chipped. Got around 50 hp and 80 TQ from the chip. You gain more from a chip on a turbo than a NA car and it sure as hell means more power and Nissan sucks with their warrenty stuff compared to most others.

I want to launch the car at 1900 rpm. Right now i leave the line at 1100 rpm. The tires spin. With the drag radials there should be no tire spinning . If Sam gets me the 28 to2900 rpm torque converter (stall) The times will even be faster. I have found that what ever you gain on your 60 ft times usally gives you an extra 1/3 off your 1/4 mile times. if i get 1 second it will lower my times by 1.3 at the other end or the track
We will find out in 4 months when the track opens.

So spinning the tires and still getting a good 60 ft. On a regular road, using my Gtech, I was getting around 2 secs for my 60 ft but still came out with a 0 60 of 5 secs. Im trying to get under 2 secs for my 60 ft. (on a regular road of course)

No.

You can modify an ECU to change an engine tune. But most of the power your getting on a turbo car from a tune comes from increased boost and timing changes. The amount of power you gain depends on how aggressive the tune is and how much boost is added. It dosnt matter how many turbos are on the engine. And if you think Nissan warranties suck then you are clearly naive.

Well Duh, thats called chipping. Dude Ive had numerous cars from numerous companies and Nissan really does try to get out of warrenty work. I dont know what cars you had but all my others never worried about my car being modified they just fixed it even if the modification caused it. And if the two turbos are differnt sizes and you have them both tuned they will increase power at different times hence more power from the two than the one. So you are saying that the companies out there right now making TTs for the Z really only need one to get the same power? So the GTR can take out one of its turbos and still be just as fast?

You both are talking about the same thing. Merc I'm 100% sure you knew what he was talking about. Freaking semantic-nazi. :)

:driving:

nice time

Good news guys, the stillen headers are on and so is the NXT underdrive pulley. Ive been busy with the Cobb and changed the throtle position settings.
The timing has also been bumped by 2 degres ( not done with the Cobb) and the Stillen CBE now fits. All the mods are on and in a week or too it will hit the dyno with the 305 ,35. 18 drag radials. Im looking for a little higher rwhp #. 308 to 310 SAE, = 318 to 320 STD rwhp.
If it was a 6 Mt it would make more power, My goal is to go 12.58 to 12.62 in the 1/4 mile NA in my 370sport 7 AT.The track opens in April.
GTM SC= 11.70 ( time will tell ).

Just got back from the dyno at it made 320.1 rwhp and 257.1 lbs of torque. Its running a little lean and i have to add fuel to the engine to richen it up .
13.68 A/F at 7950 rpm. 13. 9 to 14.1 between 5000 and 6500.
I tried a few test runs up to 120 km today and it goes like a bat out of hell.
I ran sunoco 94 for fuel with the stock 19 inch sport rims and tires
will post dyno charts this weekend.
All the N/A modes are now on the car.

I put on the 305 35 18 drag radials tonight and took the car out for a few test run.s
There is a difference in weight of 5.5 lbs from the sport 19's to the 18 x 10.5 volk t37's with the drag radials. Thats 11 lbs of the drive line of the car and you can feel the difference. You can feel the diference in mid to high rpms.
Traction is much better than the stock tires. I had 30 lbs of air in then can not wait till i take them down to 20 or 16 lbs.
If it does not rain on friday night im off to the track.
They fit perfectly on the 370z.

Are you driving around on drag radials?

Whats your 60 time?

if it does not rain on friday night i will be at the drag strip.
i drove the car to the golf course 8 km, car handled well on them, there is one big difference, the ride was a lot quieter. no tire noise.
I will post time on saturday, the weather does not look good for friday night,

The wheels and tires look great. Your Z is going fly at the drag strip with the extra power and now much needed traction to keep her hooked up!

I just finished installing the the 15 lb braile battery tonight, Thats a weight saving of 20 lbs off the front of the car. Will post picture of battery tomorrow night.
it took about 1 1/2 hour's to install it . The car started perfectly with the braille.

I posted in the 12.942 thread. Not a good time at the track tonight.

Too bad on the times, but at least it wasn't the car or the driver... under those conditions you should just call it good practice and have a beer... :tup:

This Saturday the Z club is going to Toronto Motor Sports park. My best time there so far is a 12.91. at that track.
I learned a lot about too much traction with the drag radials as the car bogged on the line last Wednesday night.
Since there's a major event at the track. It will be hard to get more than 3 runs in as our test and tune runs will happen when there is a break in the days main event.
At least im going to see some gerat drag racing that day.
The track will be fully dressed that day so the lanes will be fast.
It will be different drag racing with the stands full of people. The 370 z now does great burn outs so a least it will look good coming to the line.
Z.

What were your 1/8th ETs and MPH for these runs?

how much more gas are you wasting with the new gears?

12.86 @112.7 Was the best pass of the day.
Next time im going with the street tire's

Z

You managed a better trap speed though

Was the launch not very good?

there was too much traction 2.014 was my average 60 ft. at 1650 rpm.

Oh I see

There was a guy on myG37 that snapped his CV joints after installing a S/C from a few launches at the dragstrip, you plan on doing any sort of modification to your axles after your SC install?

:facepalm:

LOL what's with the facepalm

Probably the "too much traction" comment. Manuals are supposed to have a little spin leaving the line, autos are supposed to dead hook. Need a higher stall (or torque :tiphat: ) if you think its bogging down too much. Sticky tires= higher launch RPM.

Agreed. But he doesn't have his high stall converter yet. And no one really knows how much the rear end is going to be able to take!

I understand. Its just funny because I have never heard a complaint of "too much traction"

Haha, he is from Canada isn't he! Steve and I watched him do it!

True. I need more, that's for sure. :icon17:

I need to get rid of my 4.10s. Thats killing me more than anything.

Is it possible to have "too much traction"? You probably want just a little wheel spin off the line to get you up to speeds quicker maybe and with DR's on our cars, that might not be easy, not without a pair of snails at least.

Small world isn't it! :hello:

:iagree:
No such thing as "too much traction", just "not enough motor".

Good times regardless! :tup:

Need more motor, GTM stage 2 and a 3200 rpm stall torque converter.
Coming soon.
The guy with the G 37( stillen SC,) had toyo TR 888's and he launched at 1800 rpms and he broke the drivers side cv joint on the rear axil.

Was going to the track tonight Temp is a cool 48 degrees. But it rained all day and night.
will have to wait till next weekend.
I put the stock sport rear tire's back on the car.

Z

Going to the track with the new motordyne intake manifold.
Time will tell if it works.
It should give me a better 60 ft and 1/8 times.

Z

When are you expecting the torque converter, Steve?
