Went to track tonight. Need some work.LOL!

[Cobra351]

I went to the track tonight here is what I did.
60' -2.222.
330 -6.105
1/8 -9.103
MPH- 85.39
1000-11.625
1/4-13.60
MPH-109.0
This is with 14* of timing.
I then went to about 16* and got this.
60'-2.204
330-5.898
1/8-8.870
MPH-83.96
1000-11.350
1/4-13.49
MPH-105.89
Now the questions.Why did I run a better 1/4 mile time,but 3-4 mph slower.And why would I have a better mph with 14* of timing compared to 16*? Those were the only 2 runs I got. Now I am not sure if I should set the timing at 14*or 16* or maybe less than 14* Also this is with No traction street tires. Talk to me guys!

Traction is the issue that I can see from the horrible 60's and the trap speed. 109 is good for a mid to high 12.

just my .02

i agree with the traction. anything you can do to add any will help. you have all the motor you need, now just get that power to the pavement----without spinning!

 

[Cobra351]

How about the timing issue. Any imput on that? Will the higher mph indicate a better spot for my timing or the quicker 1/4 time and slower mph?

thats above my level of expertise sorry man

Id go with the timing set where you gained the highest mph. For now at least. Since this was the first time at the track with this car, what were your shift points. Did you spin bad out of the hole or did you launch at low rpm and ride the clutch.

Another thing, did you powershift or take it really easy. With your setup I bet you sould bang the gears and get some more time out of that car.

 

[DougNuts]

Yes, for now you want to go with the timing that gives you the highest MPH.

109 is pretty good, but I think you have allot left in that car. I would think 113-114 is possible.

how can you dream of having advanced timing with these gas prices? i wish i had enough money to do that

 

[Numbles]

Cobra351, have you had the car tuned. Seems to me that I havent heard you talk about a tune, maybe that would help your combo. Maybe even a cam suited for a 351. Ive heard that TF stage 1 cam on the medium side for a 302 let alone a 351. I think those 2 things would really let the car scream.

Ditto on the cam! maybe a stage 2 or stage 3 (definately a custom grind) will be suited better for your 351.

you can just turn the timing back down a bit when you leave the track!

 

[Cobra351]

Thanks for all the replies! I kinda rode the clutch outta the hole. Pretty much babied it till top of 1st gear, because of traction issues. I shifted around 5500rpms. I didnt speed shift, but didnt granny shift either. Kinda a happy medium. Would really like to get even a 12.99 on pure street tires. "Think it is possible?" If I can just get the 60' down a bit that would help me alot. I didnt really get to mess with F/P and timing like I would have liked, maybe next time. I was thinking about a custom cam. Maybe over next winter. Havent had it tuned, I did put it on the dyno but really did not do much except mess with putting in and taking out the diablo chip.Really thinking about the Tweecer when money permits.

 

[Numbles]

I say go back to the track and rip through the gears really good. You definately have a 12.99 or better coming.

 

[Killercanary]

I think with a little more practice you could see a 12.9 or better on street tires. I've had my combo together for 3 years now and I'm still tuning and tweaking it... and it keeps getting faster. So in other words, you have a lot left I think.

 

[swingline]

Your MPH's are there you just need to get better 60's. This will come with getting better at driving at the track or getting sticky tires. Hell, do both and you'll be really happy.

 

[Cobra351]

Do you guys think putting on a bigger throttle body would help make any more power? There is a 70mm on there now, That is what was on there when I bought the car.
