What kind of MPH is neccesary To acheive a 13.9 1/4 mile? (approx.) I am currently trapping 90.13. How much would I have to try and raise that?

(I know I know, bench racing, but I am new at mph vs. ET.)

 

what tires your using??

 

Shitty street. That's why I wanted to know the MPH.

I won't be able to tell what my car's ET should be because of lack of traction. It'd be nice to know a MPH to aim for, so when I can afford slicks, I know what to expect.

 

95-96 mph on slicks.

99 - 102 mph on streets.

On a FWD vehicle typically. At least this is what I`ve found.

Thanx bro.

 

weight has a lot to do with it also. what times are you running @ 90mph.

with a 2600lb 2000 H22Hatch it took 99mph to run 13.9's.

Weight doesn't have alot to do with trap speeds vs. MPH, it's traction and powerband that has much to do with it.

How does that help him know how much mph it takes for a 13.9?

This is a good ruff estimate to go by. Here are some corresponding times to reference to. 5 and 9 are the same car, same driver, same track.

1. 93 Civic SI 13.6 @ 102
2. 93 Civic Coupe 13.67 @ 100.3
3. 00 CIVIC SI 13.92 @ 98.6
4. 90 Integra 14.01 @ 97.61
5. 92 Civic Hatch 14.01 @ 95.94 (slicks)
6. 95 Civic EX 14.06 @ 100.41
7. 88 CRX 14.07 @ 97.50
8. 91 CRX 14.09 @ 99.8
9. 92 Civic Hatch 14.15 @ 99.5 (street tires)

 

I pulled a 15.5 @ 90. That's before forced induction.

 

I got a 15.6 @ 90 with a 2.6 60ft time on street tires, and this was my first time at the track with my H22 accord. A lot more tire spin than my B16 in my crx The MPH isn't what you need to be focusing on because the car is obviously accelerating quickly all the way down the track. If you are spinning off the line, drop your launch RPM down a bit untill you have minimal tire spin. If you are bogging, launch higher. Make sure you do a good burnout to get the tires nice and warm. 1 tenth of a second off your 60ft could be 3 tenths saved at the end off the track.

Keep practicing and good luck.

 

I did 13.9 with 97mph and a 2.1 60' ft. That was with a ITR trans so it can vary upon gear ratios.

 

I would say 94-96 MPH will break 13's. Depends on the size of the slicks and the air pressure.

id say 100ish...maybe 98-99mph for 13's. that is with a decent driver...

 

back in the day in my ITR full interior all motor...

14.000000009 @99.99999mph lol
2.1 60ft on street tires

I was so mad

 

General rule of thumb for a fwd car is 13.9@100mph. As a couple of people have posted it is possible go 13's and only trap 96-97. Traction, gearing, and a ton of other factors all have an effect.

Usually the harder you hook the lower your trap speed will be. If you are going 101-102 on street tires with a crappy 60ft you should have no problem going 13's once you get some slicks even though your mph might drop down into the high 90's.

 

Nah it takes alot less mph than that.
Here are my Allmotor SOHC CRX (2000lbs) times when it first went 13's

On 14 inch street tires = 13.96 at 97.0 mph w/ 2.02 60'

On 14x8x6 M/T slicks = 13.68 at 95.7 mph w/ 1.80 60'

 

Rougly 100 mph should get you in the 13's. Yet, there is more to it than just MPH.

you wont trap as high as a b-series...you should know by now that you SOHC's have a tad bit more torque...lol

 

My setup...

94cx hatch + GSR w/boltons and Nitto NT555R drag radials on HX wheels =13.9 @ 96mph

Hells yeah biotch.

 

my stock b18 with 191whp went 13.6 99.9 mph so 95-99 will get u into the 13's

 

when my B16a was stock w/ DRAG turbo kit shitty toyo tires running 7psi went 13.7@105.

 

13.82 @ 101mph
2.20 60ft

13.93 @ 100mph
2.40 60ft
