last weekend i took my bone stock srt-6 roadster to my local 1/8 mile track and it ran a lowest time of 8.3 @ 85 mph . What would this time be in the 1/4 mile

 

Hard to say. They fall off toward the end of the quarter a bit. Most average low 13's totally stock, with mph in the 107-109 mark. What were your 60' times?

 

Just Google 1/8 mile to 1/4 mile calculator and some will come up. They are all pretty good but some factor in frontal area and more definitive info.

 

my 60ft time was 1.9392

 

Unfortunately it takes skill and experience ..... or dumb luck to do better, even with some modifications. A well prepared track helps too. My best time slip is 13 at 109. The last time at the track my best was 13.2 spinning, off and on the gas, spinning some more etc. My best time bone stock was 13.2.

i was reading ur signature with the mods you have now what kinda times are u gettin so ill know what to expect . im gettin ready to put my srt under the knife lol

 

Ok, I went through my time slips, and have some comparisons that will help you translate where you are today and where you can expect to go. Please bear in mind that temps and altitude have a significant impact on this.

This was my best time with everything stock with the exception of a NW single CAI:

60' - 1.851
330' - 5.307
1/8 ET - 8.184
1/8 MPH - 85.04
1/4 ET - 12.734
1/4 MPH - 107.65

With NW CAI, C3 pulley and Tune:

60' - 1.804
330' - 5.147
1/8 ET - 7.901
1/8 MPH - 89.17
1/4 ET - 12.222
1/4 MPH - 114.07

My numbers with a single cai are pretty close to what you ran, so hopefully you can make an extrapolation from that.

BTW, those are great numbers for a bone stock SRT Roadster....... The numbers that I posted with just the NW CAI were wit a DA of 1828 and a temp of 73.

 

I just need practice. On the dyno 1/4 mile I did 12.2 but that shows what the car can do and not what the driver can do. The track close to me closed so I haven't been in a long time either.

A lot of it is all about the launch...especially when racing another car. Reaction time comes into play while racing the other individual, but the launch is important to get to the other end in the least amount of time. Practice, practice

 

Yes,
You have to be very careful what you had for launch

 

Those were my exact times except i have a dual cai intake. My best sixty was 2.08. Its a 12.8-13.0 run

 

When I was stock best I ever did was 12.7 with street slicks...best on street tires was 12.9.
Those times were done on a very well prepped track @ Joliet.
