Went to TnT on Saturday for the first time out this year.
Conditions were pretty good.
Air 75-78 degrees
Humidity 35-45%
Head wind 10-20 mph with 30-mph gusts

I got in 9 passes.

First 3 track was cold, no hook - all 12.5's
next 3 hooked good all 12.2s
then a spinning 12.3
then a good cool down and a 12.183 @110.47
then another 12.28.

I'm thinking the headwind was adding one to two tenths and taking away one to 3 MPH off the top end.
Sound reasonable?
Good news was that I was shifting at up to 6,000 rpm and was not getting the valve float, that I had been having the last two times out.

may call that into question a bit.

Dan, I like the way you post your results... always informative..wind, temp, air etc.....:yes:

What were the 60 times on the cool down run? 12.18 and 12.2's.

 

[Little Red Wagon!]

sound's like you had good day. Nothing broke and you had fun. That's alway's a good day in my book

 

[ZNova]

Dan,
I see what you mean about inconsistent traction. What size tire are you running? How many runs on them?

 

[mdla]

Sounds like a fun day. I'm jealous of your nine runs. I went to tnt on Sunday and only got four runs in five hours. Hurry up and wait...

 

[John65ss]

Dan... is yoru combo posted anywhere?

Also, just curious... you still have that '96Z you were driving at PRP when I met you way back in 2001 or so?

 

[Dan_Lebherz]

60 foot time on the cool down run was 1.691 with a 7.720 1/8 mile et and 12.183 1/4 et. Shifted 1-2 at 6,000 on that pass.

Best 60 foot of the day was a 1.671, with a 7.748 1/8 et and a 12.243 1/4 mile et. Shifted 1-2 at 5,800 on this pass.

Seems like I was heading into a head wind on that pass as you would have thought it would have been quicker.

I haven't posted these latest passes into my spreadsheet to review my interval times yet. Might tell me if I have lost or picked up in any particular interval.

First look appears like it may have liked the higher shift point.

This one local track runs TnT on Saturday afternoon/evenings when the other local track is running their regular race program. I was getting 12 runs in last fall. I do make some hot laps, I am not necessarily doing a full cool down between each pass.

John, yes I still has the '96 Z/28. I think I will try to sell it this year. I need to make room for a new G8 GXP or a new Camaro in the next year or so.

My daily driver is a 2005 Impala SS.

Cool!

We sold my '95 mustang GT last summer and bought a 2004 Impala for my wife to drive. So far it has been a great car.

Is this a Vortec 383 combo in the Nova?

 

[Dan_Lebherz]

John,
could have sworn I had posted this build, can't find it at the moment though.
I'll have to post on the other string.

Anyway, same carb (650dp), manifold (RPM Air gap), headers (Heddman 1.5" primary), trans (2004R) & rear(3.73 posi) as the 355.

I did a ghetto port & polish on the Vortec heads, and had 2.02 and 1.60 valves installed. The trans has been freshend up, new 3,000 stall Vigilante converter. 6" rod cast crank forged piston 383 short block. I am still running the 2 1/4 exhaust back to Summit Turbo mufflers exiting at the rear axle which I believe is pretty restrictive, especially with the 383.
Cam is the Comp XE288HR retro fit roller.

I got it back together the middle of October last year and got about 25 passes on it by the end of the year and 9 last Saturday.

I have a used set of Hooker Super Comps that may go on this weekend.

Still driven back and forth to the track.

The converter took the 60' times from 1.90 to 1.70 and sometimes a little better, I think I got a 1.65 or two last fall.

I think with a little tuning, it should go 11.9's.

I have one or two passes so far at 112mph, but frankly all passes have been in cooler temps and lower humidities. I was hoping for more like 114-115 in those conditions. I'll have to find a few more ponies somewhere.

 

[John65ss]

Those Precision Industries converters are great. 0.4 sec et gain on my mostly stock '95 Mustang GT with no other changes, and 100% streetable, even in the PA winters. Had ~70k street miles on mine, and many passes and the AODE trans and converter were still working like new when I sold the car last year.

new 3,000 stall Vigilante converter.....

Dan,
Your setup is very similar to mine, hope you make into the 11's bcuz that's where I'd like to get to :yes:. I think those Hookers will get a bunch more HP, the 1-1/2 primaries are choking your motor. I just bought a set of Hookers for the same reason, looking to pickup another 15-20 HP. Good luck, keep us posted on results.

Any advice on how to get more consistant 60 fts? I've had a 1.65 one run the 1.79 the very next doing everything the same in the same lane .

 

[Dan_Lebherz]

Wish I knew how to be more consistent myself.

I always start out with 17psi in the tires.
If they do not hook, I lower by a pound and try again.
I always pull through the water, those guys almost always have too much down on the track.
So, pull through and do your burnout on the other side.

Run it up to 5,000 rpm or so and hold it just to the point where the tires are starting to put off some smoke. You don't need to do a monster smokey burnout, just smoke them for a second or two.

Pull up to the line and try to stay position your car in the lane over top of where the last guy just ran. The track shoudl be warmer and stickier there.

I have been leaving from idle and just stomping it on the last yellow, but admittedly I need to experiment some more with this new combination.

With the old combo which was stronger on the top end than the bottom end, I almost never spun off the line. This 383 has a much stronger low end than the 355.
