Please post an 11 sec stock timeslip..

[Z06-Dave]

I have minor bolt on mods and I've about given up trying to run an 11, I'd like to see where I'm going wrong.

From Saturday Maple Grove, 66 degrees, 60% humidity, 800 DA

60' 1.899
1/8th 7.896
1/4th 12.151 @ 115.93

Do I suck at the beginning of the race or the end?
I'm ready to pack it in for the year, I just can't hit 11!

Help

I have Drag radials, intake and exhaust. 380HP
I think I may have false KR in 4th gear, can you tell by my slip if my top end is weak?

Dave

Great minds think alike I was about to say the same thing

Looks like you are doing just fine for bolt ons and drag radials. 12.1 with a 1.9 60 foot is respectable. I suspect if you cut you 60 foot down to 1.75 you will defintley run 11's.

1.89 usually won't cut it. You need that at least in the 1.7s, which is entirely within your reach with DR's. Just need to refine the launch.

as far as the mph, I've run 11.69 at 115 before when I had the stock cam. What did I 60 ft? 1.62

[phantasms]

I hit 11's without hitting 1.7's



that was with only stingers and tires

going next week with current power to try and hit 11.5's

It's you 60' time as mentioned above. Even a 1.80 would give you an 11 sec. timeslip. Also, why pack it in now? The weather is just getting good for dragstrip. If you run the same run above in 45 deg weather your in the 11's Goodluck!

i found an older slip when my mods were basically the same as your's (380rwhp) ... I had an 1.89 60ft, 7.63 1/8th (95mph) and 11.82 1/4 at 115.5 mph....something i noticed for my car was i had better 330ft 1/8 and 1/4 if i had a little spin at launch, no bog - it kept the front end up so no momentum loss (?) ... I launched around 4000rpm on DR at 16lbs air pressure...i could get a better 60ft but if it associated with a bog then other times suffered...after more practice and hp i got 1.7 60ft with a little spin...also best times resulted when i powershifted at near rev limiter...I know several who "short shift" 1-2 and then near rev limiter for 2-3 and 3-4.
my suggestion is practice with a little higher rpm launch, shift near rev limiter and for sure go to track after weather cools to 60* ... my very best times were in 40 -50* air temp.

Kat...Which cam are you running with those heads?
Can I have some more specifics on your car, I want those heads and was wonder about push rods, cam, clutch, hardened input shaft???, etc...
I think it would be a nice winter project for me.


Robz, when is your next trip to the strip? Maybe I'll head down and you can help me, or make a pass in my car so I can see that the it is capable.

[robz]

Be glad to help. As soon as my car is up again, I'll meet you at atco and we'll get that 60' time in the 1.6-1.7 range. Hoping to be up soon.
Let me know anytime you want to go.

Sent a PM as not to thread jack.. Then I realized you started the thread

Below is the info on our AFR H/C package
First Impressions - AFR 205cc heads + AFR 224/228 cam.

We are running the Exedy Dual clutch. This clutch is probably over kill a single would have been fine. But I never wanted to worry about a sticking clutch pedal ever again. I can't say enough good things about it. With limited seat time we have had in the car. Neither of us has missed a shift

We currently have the Rockland Standard Gear hardened output shaft installed.

We are looking to getting the car back on the road by the end of the week.

The launch is everything. I'm running a Ziptie and Nitto DR's. My best run for this summer was : http://www.aliencodec.com/qksvr/Z06Timeslip.JPG

i feel for you. i too have given up on 11's for this year (only one more night at our local strip left in the season). my best with 405rwhp and nitto r2's is 12.31@116. DA is probably somewhere between 1500-2000. i know my 60' is the weak spot at a best of high 1.9's. i have tried many different launch techniques with no luck yet. maybe next season with more power and different tires i will see 11's. i've never raced at another track either so i can't say how well this track is prepped.

You and me both, I might try another day with robz's help, if we can hook up sometime. I think I need to see my car to do so I can see its capable. Then I will be inspired again.
What mods do you have to get 405HP??
I have headers, vararam, stingers and no cats, I only have 380.

Hey Dave, How's it going?

BTW--what are your shift points?
