official 1/4 mile track times

40 degrees is great. Was it raining/very humid??

As far as 2.29 60' ? I'd rather not comment. Is this your first time at the track? What tires/wheels are you using. I can help only if you like. I don't want to be in a position where help might not be wanted. Before you answer, I have to tell you that if asked, I will be brutally honest. Not a believer in that new teaching that " we are all winners" "everybody gets a ribbon" God forbid the a kid comes in dead last in his school's running race & doesn't get a ribbon.

first time at the track with the Z. did couple more runs were both about the same 2.2-2.3 60ft. sport wheels 19x10 on continental DWS. I would spin really bad off the line if i launch more than about idle-1200rpm, (I know i need some RE-11's or a different wheel/tire package, and some gears…….
humidity was about 70% and it really felt less than 40deg.

You have large wheels & tires + no gears! That = less than just no gears.
You must be a good driver to get to that time & MPH with having so much against you.

Your second problem is that with headers(not needed) & test pipes, exhaust plus no tune = your car running very lean. Not only performance suffer but it is not good for the well being of the engine.

When you make so many changes, a tune is a MUST!!! You need the timing, fuel, everything adjusted/matched up to the NEW/DIFFERENT working PARTS.

Also these mods are for high rpm H.P. So that's another reason for gears.
Not only it takes you a long time to get to top/high H.P. but after every shift the rpm drops so much that again you are far from your high H.P. It's almost a miracle that you did this well.

Just get smaller/lighter wheels for the rear, plus a set of M/T or Nitto street/drag radials. You can drive with those to the track, then drive back home.

So get 4:08 gears, 17 or 18 inch wheels apx. 275/40/17or18 tires. Plus a good shop to get an Osiris uprev tune.

Then go to the track on a cool day, heat up the tires a bit, drive the same way but after the tune you'll be shifting a bit higher(rpm).

I will clean your car for a year if you don't break 12.8 @109+ mph.

Umm I have cai, LTH, basically a straight pipe CBE and still running rich as when I was almost stock. There's no way he's running lean if I'm running rich. My motors well being is extremely safe at about 23-24 degrees of timing and 11.9-12.4 AFR. This was all logged and dyno'd.

I also don't 100% agree with lighter wheels/tires/flywheel/pullies etc on a drag car. When shifting the rpms will actually drop faster than if the car had heavier components that keep the inertia up and spinning. The OEM wheels are light enough.

I tried one final time at the strip before they close for winter. But I had an unexpected traction issue caused by leaves falling all over the staging lanes all day. So I only managed to get a new slow time for my car of 14.8@107 against a Civic on slicks. I struggled for traction all day, and on my final run I didn't bother spinning the leaves off my tires before the launch, and managed a spintastic 2.8 60 ft.
