went to the track a couple weeks ago figured id see what you guys think

60' - 2.3
1/8 - 9.54
1/4 - 14.65
mph - 95.84

i think i may have been able to shave another tenth off with a longer cool down but this was the best of the night on stock rubber car is 98 lsc

mods are:
4.10 with trac lock
tune
UDP's
third cat removed x pipe
 
Yea you have a lot more in it with a better launch. A 2.3 60 foot time is terrible, worse than stock. Were you spinning?

Not with his mods. He has stock intake and log manifolds.

If you want my opinion 4.6mark, your times seem right in line with what you have done. I ran a best of 14.1 with a stall converter and headers to full exhaust with my stock intake back in 2010. Take away those two things and I would have been running around your time. Nothing seems weird here.
 
sounds good at least im on par...

i was on absolute crap street tires but track prep was really good so it did spin a little bit but hooked up quick

ill be heading back to the track again soon after i get the cobra intake installed and see how much i improve

You'll improve a whole lot more if you ditch the log manifolds. I know it's a hard pill to swallow for many because of the price of the Kooks, but I'm telling you with full exhaust and headers, the Cobra intake will uncork something very nasty. A stall will take off another very noticeable amount of time and by then, you'll likely be running 13s.

Regardless, be sure your shift points are set higher with the Cobra intake. That intake manifold does A LOT better with more rpms.

If you spun a tad but hooked up quick, you'll probably get 2.1-2.2s dead hooking. Just a guess. In my experience, getting quicker short times is a whole lot harder than getting quicker 1/4 mile times.

If he can get it in the 2.1 range that at least gets him 2 tenths faster. Even I had 60 in that range on my :q:q:q:q tires. A really good launch will helps lots

Short times are not directly proportional to 1/4 mile times. Keep in mind, I'm saying directly proportional, NOT a direct result, because quicker short times generally do mean quicker 1/4 mile times but it is not a "tenth-for-tenth" I was running 2.1-2.2s in 2010. My best short time now is 1.94 and I am 5 tenths quicker. ;)

In regard to this topic, Burbank LSC got his car in the 10s with 1.5xx short times. See what I mean here. ;)

I see what your getting at. All I'm saying is getting it down won't hurt
 
The general rule of thumb in drag racing is ever tenth in 60ft is worth 2 tenths at the 1/4 stripe. I see a 14.45 in that car with a 2.20 60 ft which it should easily do. I would hope to see 2.1XX 60fts for a 14.3XX from you.
 
For every .1 in the 60 foot time will get you .15-.2 on the top end. A stock Mark VIII should be able to pull a 2.2 60 foot time no problem.

Oh, I totally agree. Just clarifying. ;)

I agree with everything you say but am confused about your first sentence. If that holds true, then if a stock Mark VIII gets a 2.2 60' and we assume it runs a 15.0 then that means that the guy who ran 10s with a 1.5xx short time should have only ran 1.4 seconds faster. That would put him at 13.6 if you are saying short times are directly proportional to ets. I don't know if I believe the rule of thumb. What was your 60' time when you ran your 13.31?? ;)

It depends on your power level. The faster the car is the more it picks up on the big end with a faster short time. I think a mark viii picks up around .15 for ever .1 on the short end.

Alrighty then. So you clarified what I said then.:p There are too many variables in drag racing, including power level, to say that there is a specific mathematical formula to determine what your short times will be. Look at your GTO for example. It's obvious that your power level is greater on that car than any Mark VIII that would likely run 13s with that short time (1.95) You ran 12s. You had enough power to pick up a lot of ground after the car got out of the hole.

Let me share what I have seen as typical short times after looking over timeslips for the Mark VIIIs, which no one can dispute. ;)

2.0+ = 14s
1.8-1.9 = 13s
1.6.-1.7 = 11-12s
1.5 = 10s (BurbankLSC)

Key word: "typical" Results may vary a bit, but there is a lot of consistency in the short times on Mark VIIIs in comparison to what they are running in the 1/4 mile.
 
i agree that my 60' should have been better, it was my first time at the track with the gears in and before that i hadn't gone in maybe 3 years

i think with a little less tire pressure and more aggressive launch on top of a longer cool down i could have done better

after the cobra intake headers are the next upgrade

If someones car is not set up properly to drag race those are the variables you talk of and of course you cannot tell 60fts exact. But for a set up drag car that does what its suppose to do yes there are dead on formulas that come out spot on for every speed and time.

You will man. Practice makes perfect. :)

I agree with you Frank. ;) Like bracket cars for example. The more consistent the car is the more likely that one can actually incorporate a mathematical formula to determine short times. The only thing that I am saying here simply is that it is not "tenth-for-tenth" or even "tenth-for-2tenths". If you watch these fast and very consistent bracket cars like I have, the "tenth-for-2tenth" formula never holds true. I'm not saying there isn't a formula but I just don't think it is the one mentioned here.

Here is Charlie Odden. One of the most consistent and best bracket racers I have ever seen. He runs 1.4xx short times. Catch the triple 0 light on the board. ;)

I can't wait to get my dyno tune. The bad part is they are packed out for a month. My appointment is Aug 6. I'm hoping for similar times since our mods will be about the same
 
Fwiw i pulled a 2.31 on the pass listed in my sig. Best 60 was a 2.19 on a different night. Iirc that pass was a 14.4
 
What were the temps at the time of your runs? My old 94 ran a 14.651 at 97.21 stock, but it was in great air at a very good track.

I think you are trying to hard to correlate 1/4 mile time to 60ft time. You can't compare the numbers across different cars or power levels. My Buick pulled a 2.22 60ft and ran a 13.03 (No posi lol). I could also make a stock engined mark pull a 1.6 with the right converter, suspension, and gears but it would suck in the 1/4 mile.

What every one is trying to say is that he hasn't optimized his combo yet. A mark with 4.10s should be able to pull low low 2.0s to high 1.9s and it should lead to a quicker time out the back end getting a lower 60 with everything else being equal.

If you didn't pull your fastest 1/4 ET with your best 60ft of 2.19 that just only means you went slower somewhere in run from heat to shifting. To me I would not be happy till I ran a 14.2 ish with your better 2.19 60ft.
 
If you want to take the launch and traction out of the equation, look at the MPH when you're going through the traps..compare it to another mark that's hitting 95 mph in the 1/4 with no traction problems and a better 60' and that should tell you what it'll run.

The air was cold and dense on that pass but the track was glass. On the 2.19 it was in the upper 60s and the track was nice and sticky.

I would have to pull up the records but iirc da was -300 or lower for the 14.3
