How to run 1/4 mile, First time

megalapagas

So your saying if flujoke's reaction time is a full second he's still going to hit 13.2????

Yes, you can sit there as long as you want after the light goes green. It will add time to your reaction time but your 1/4 mile timing doesn't start until your car moves forward.

Maybe next year when GLD is open we can meet up. I went on 11-9 and it was fun.

Very True....Reaction time only matters if you are racing an opponent and want to be the first across the 1/4 mile....However IMO Drag Racing is really all about racing and beating yourself to achieve your best time......

Yep the time doesn't start when the green light come on it start when you take off.

When i was at the strip, i launched at 3500rpms and the car had so much grip it bogged down and bucked. So the next time i launched at 5000 rpms and it hooked up nice a took off. Drag strips have rubber laid down from all the burnouts so there is a huge amount of grip compared to the street

Im at the strip now, cecil dragstrip in MD. Not having good runs, doing 13,6-13.8s. Im
In a MT, should i be launching at 2500~ or 4000~? Also, im
Getting wheel hop / bogging down.

On hankook ventus v12, 285 wide temp is 56 deg

I feel your pain...

Summer tires on the Z don't work well at the dragstrip.
Wheel hop is definitely not a good thing.

The best launch is a combination of factors - Tires, Temps, Track Condition ...
Finding the right balance takes a little practice.

A quick but not too abrupt coming off the clutch without feathering it along with an equally smoothed transition on the throttle without wheel spin or bogging is the goal to shoot for.

With street tires you can't expect too much better than about a 2.0 60' time.

You can improve your launch and 2nd gear with drag radials - Mickey Thompson makes a 305 that will fit the stock 19" wheels.
They will stop the hop as well...
They are made of softer compounds and have a softer side wall.
Find another set of 19" Z wheels and put them on when you want to go to the drag strip.

What was your trap speed ???

104.87-105.34 was my best. I was getting clutch slippage off the line and from 1-2 change, bogging down, wheel hop. Did 7 runs.

Chime In ? Please do !

ok here's a few things. and most are aimed at the OP to help him and his AT run a good ET.

also some of these points may have been made but to be honest i didnt feel like reading every post. sooooo get over it.


1. you can go sub 2 second 60' on street tires.

here's a list of the top 1/4 mile ETs with street tires aside from #2 Z eliminator had drag radials.

MODIFIED - ALL MOTOR
1) jnaut ------------ 09 Base Sport 6MT 12.245 @ 111.81 mph 1.813 60ft street
2) Z eliminator ----- 09 Tour Sport 7AT 12.420 @ 114.37 mph 1.854 60ft DR
3) ts-c63 ----------- 12 Tour Sport 7AT 12.777 @ 108.23 mph 1.913 60ft street
4) secondnissan ----- 10 Tour ----- 7AT 12.856 @ 106.25 mph 1.944 60ft street
5) tranceformer ----- 09 Base Sport 6MT 12.860 @ 109.09 mph 1.921 60ft street
6) FPenvy ----------- 09 Tour Sport 7AT 12.899 @ 110.74 mph 1.950 60ft street


2. launching the 7AT does nothing from what i'm tested. anytime i've pre-loaded RPMs it just spins tire and costs you time. and thats with VDC off. there is really ZERO reason to do a 1/4 mile on a prepped track with it on. most times you'll get traction and the slightest slip with kick in VDC and bog the throttle to compensate. it's more effective to modulate the throttle slightly with your right foot to stay in the power and kill whatever spin you need to deal with.

3. the guy who said reaction time improves your ET someone please smack him.

4. please dont run a 1/4 in drive anyone the ECU for the tranny shifting is awful when going balls to the walls. put it in manual mode, do some runs, learn your car ,and hit those shift points hard. you and your ET times will thank me later.

5. street tires dont need burnouts. drag radials and slicks do. i mean have i done a burnout on street tires.....yes who haasnt. and yes i have done mini one here and there at the track to clean off any debris on bad days there. no full smoking pouring waste of my expensive street tires ones.

6. use the paddles. there is no difference in their shift times but its safer and less motion for your finger to pull that than the time it takes to move the stick. everyday driving i use the stick and racing applications i use paddles.

7. on the start you want to drop the hammer before the green pretty much you're going to want to hit it on the last yellow. also this is very dependant on where you stage. if you stage deep (far up) then it will take less distance to break the lasers. shallow would be the opposite obviously. soooo depending on how well you react and how your car gets off the line (all done with practice) then you will know where is the best place for you to stage based on your car and driving.

8. shedding weight is fine but i got a very fast 1/4 with full weight (minus cats), full tank of gas, and not a single thing removed from my car.

9. i've never changed my tire pressure once when i got the track. how i drove in is how i race and drove home. probably around 32psi on PSS's. never had any wheel hop ever. you people confuse me when you say how much wheel hop you get in many situations.

any more PM me
