Yeah, I had a "code brown" moment merging into traffic this morning. Completely forgot how much of a difference it being 40 outside instead of 80.

It never really was a big deal to me until recently its been getting on my nerves. I am personally more of a go fast for a long time person... so I have always been more concerned with nice brakes and high speed stability than I was concerned with the first 60' of a drag race. Most boosted Z's are setup similar... street cars that are setup closer to a road race car only with more power than they could realistically road race with.

The car is the problem. Its the design of the IRS. Guys with Vettes and Vipers and what not can run around with 600rwhp, on just decent sticky street tires, and still get OK traction. The Z is a whole different story. Z owners build up to that generally totally reasonable amount of power for the street like 550-600, and only find out when they get there that the Z suspension is NOT up to the task without dedicated slicks. Most Z owners just arent into that.

A 600rwhp car shouldnt need full slicks to not roast the tires at 60 or even 80mph. Not many guys are expecting that when they start building their Z. I wouldnt tell them to get slicks because of it... because that is not what they wanted to build.

We should do & not do whatever we want with our cars. If the subject of drag racing comes up, you & others should not jump out of your seats because you can't do it, or don't want to. Whatever....

I'm fine with that. 100% fine. Just don't say others can't do it, because with a little effort they can...... You can't then don't.... I've got nothing more.....

No problem. I saw your post but I am not sure the answer. I was under the impression that the ABS rings were the same from 2003-now on all the Z's

Now I don't feel so bad. I've been dragging since 16 and have had many fast cars. My last WRX with a measly 335hp could run 11.7's. Hell bone stock I ran 13.3 at 101!

Now last summer I have a gutted rear 370z with a CBE and 285/35/18 HTR Z3's that couldn't break 14's at 106.5mph! Stock rear camber was -1.9 and -1.4. If the camber does change than no wonder I couldn't hook up! Its a hell of a highway drag car though

This is what Im saying I think is about the current limit for our IRS and 18" drag radial. Anything is possible but I don't imagine beating it by much without a slick or really custom suspension work. Maybe if you went real dedicated like positive camber... But what I'm talking about is realistic expectations for the norm, not the rare few that best it.

Copy and sell us the quicktrick alignment setup. You can knock out your own alignment in the garage or at the track in a few minutes. Positive would then be the norm for us all.

I've thought about buying one of those just for myself! I might end up needing one

It looks like the oil pump failed. It was turning 8100 when it let go.
No parts came out or the engine. Something broke in the drivers side cam gears.
I drove it and it stopped 60 km from home , I had it towed .
GTM will have my 4.2 finished before Christmas with a stage 3 SC.
All the toys including cams will be in this motor.
Oh yes lets not forget the meth.

GTM traction control did not work for at the track.

i may not have set it up correctly.

Up date

Big power for my car is coming from GTM.

305 35 18 's MT drag tires may be too small.

Thanks for the $$$$$$ update !

Weather held up today ... Track temp in the '40's.

Ran 12.407 @ 116.31 - still with a 2.004 60' time tho.

Tried a few different settings with the GTM Race Logic ...
It did help to keep the car planted with the 2nd gear shift ...not too sure how much it helped in 1st off the line.
Too early to tell ... gotta think through todays runs.

The tires were cold ... with the Race Logic it is more difficult to do a proper burn out...need to look in to that and figure out what to do too.

It might be also the clutch that is a weak link now...encountered some slip'n and smellin'.

oh - no back in to the shop again !

gittin' in the 10's is also my goal as well ... but first the 11's ... & got to get a deeper wallet too...

The launch control will work with the 6 MT.
What mods are on your car.
Great time.
Pm your phone # and i will give you my tire set up for air pressure and launching the car.
my 60 fts are 1.80
There is no disk for the launch control as far as i know. Did you get the GTM manual for the TC.
