Finally got me new combo to the track. 3,700 lb 69 Gto full trim street car drivin' 25 miles one way to/from the track.

Jeff/Shaker455 was a great help in getting the car right in short order on a very hot humid kansas night at test and tune. first run was a 12.66 at 109, called Jeff as he had set up my 1050 quick fuel carb and he dialed in my timing and jet changes in short order! result was a 11.99 at 115mph

heres the results, 60' times are off but that's under diagnosis. still a lot of fun beings a casual racer. can't help but wonder how much faster the car will be getting it right? thoughts?

12.66 at 109, 1.9545 60ft
12.62 at 111, 1.9528 60ft

shaker455 called...lol

11.99 at 115, 1.8281 60ft
12.07 at 115, 1.9024 60ft
12.00 at 115, 1.8253 60ft
12.05 at 115, 1.8365 60ft

60ft times buggin me!

Sounds like a good first time out. Long as you had fun thats all that matters!

[adam woodmancy]

Wow.. great times for those 60 fts... My 12.70 street car will 60 ft 1.65-1.70 with the drag radials and 400 cubes and a 3.73 gear. Your ride still has a load of potential I'd say. Congrats

[shaker455]

Eric,
A great 1st night out at the track with your new combo!

You should post up your video's...my son was all over that!

There's more in your combo for sure!

Thanks for having me for part of your build
Jeff

lil more on the combo would help to get to diagnosis.

[johnta1]

Good ET's!

What kind of tire/slick are you running?

For 1st time out with it, not bad.
Definitely will be quicker with more testing/tuning.

It's all here: """"".butler race port 85cc round port e heads 308cfm @ .600, port matched victor intake with 1" wilson tapered spacer, 4150/1050.""""""

What was Initial ADV & Total ADV, or was timing locked-up at TOTAL ADV?
What Octane fuel did you run?

Great MPH for the 1st time out. Time to focus on suspension

[johnta1]

What's your shift point?

Have a pic of an ET slip?

I'd say a higher stall converter would help a lot.

[Cliff R]

Pretty "soft" 60' times for the combination of parts. It should EASILY go in the 1.7's if not 1.6 60' times with that gearing/converter.

Tune is still off some, IMHO, and must have been WAY off the mark to find 6 tenths and 6 mph and not much change in 60' times. I'd keep hammering away at the tune as well, and working on launch technique, getting heat in the tires, etc, to get the 60's times down some.

A 3000 flash converter should do fine for what you are doing. Unless you've already tried it, I'd try leaving off idle to help it lift the car and hit the tires harder, in lieu of loading it up on the starting line.......Cliff

What track in Kansas?

[ponjohn]

Nice tuning.

What rpm through the lights?

[JUDGE3]

began with 18 deg initial/35 total timing in by 3,000rpm, carb jetted 81/90, 12.60's at this set up.

changed to 22 deg initial/35 total by 3,000 rpm, rejetted to 85/94, resulted in 11.99 to 12.05

shifted at 6,150

ran vp/c12 fuel

my track is kansas international dragway

didn't get a glimpse of the tach thru the traps but my shift light is 6,150 and it did not light.

my 12.62 run had a 330ft of 5.4188
my 11.99 run had a 330ft of 5.0723

working on scan of slips and video post

thanks for any and all assist.

Eric,
You may want to make mention that you uncorked your headers at the track and didn't mention that until the next day.

Yeah.. that can throw the tune off a bit.....

But that's okay you called after the first run and you saw lean plugs...

We were in process of jetting up until it slows....night goes fast.

Yes I had open headers and failed to mention that.

Jeff, Thanks for all the help. my combo wouldn't be where its at without it!

Leave the exhaust on if it's tuned for it. I love the sound of my cars exhaust through the pipes going downtrack... Not a hp killer either...
