Full weight GTR? Stripped out? Full street tyres, drag radials, DOT tyres or full slicks? What kind of transmission?

Depends on whether you are building a full on drag car or want to do it with a full street car.

Mine is r32 standard weight and gearbox, 400rwkw and fedral street rubber i ran 6.8 @ 107mph for 1/8 mile. 60' was 1.64 on that run but have done 1.57.

Other r32 with similar power and 1/8 times do around 10.4@136mph.

Looking to push a little more power out if mine ( just wondering hiw much miore i need) and prob get sum drag radials on the rear.

Anyone know what 1/8mile time to do 9.9 sec 1/4?

How about you suck up, get off the pussy 1/8 mile and live your life a 1/4 mile at a time

Oh and in absolute theory your 1/4 time will be double. So you would have had a 12 sec pass

Thats bad theory seeing as your already doing 107mph.

This 10.2sec pass is close to your 1/8 pass times and speed

No in absolute theory seeing as you have to travel twice the distance and it's taken x amount of time then x times 2 = result. Not power curve, inertia, speed already travelling.

Absolute theory. But how about he just goes to the 1/4 and do it. Wouldn't that be better than him telling his mates that he has a 9 sec car just because he trapped 6 sec on the 1/8 mile?!

f**king dumbfounded I am.

What the f**k, are you serious ?

SPEEDS IS NON LINEAR DUE TO SOMETHING WE CALL ACCELERATION.

GET TO THE CHOPPPPPAAAAAAAAAAAAAAAAAAAAAGGHHHH

More info on these 400kw 32s that run 10.4 what tyres?

Mine should make 370kw once its done so with the above I should crack a 10?

Seriously, those clowns bagging out the OP for his question and for trying to convert 1/8 mile times etc should wake up...If you look closely you will see that the OP is from SA where they only have 1/8 mile track to utilise and hence why the question is being asked...I'm sure that if the nearest 1/4 mile track wasn't over 1,000km away things would be different.

Stop bagging people and post info that is actually relevant and provides postive answers.

sky30,

There are calculators for various conversions that can estimate times. ET. MPH, and horsepower given a set of parameters. This even includes an 1/8th mile to 1/4 mile converter.

See here for one such page with these calculators:

http://www.hotrodpitstop.com/tool.php

Bare in mind that most of these types of calculators are US-based so they will have weight in pounds with horsepower at the crank. Other pages/calculators give the option to input hp at the wheels.

Be warned - with drag radials there is a fair chance you'll smash a front diff if it's a stocker. Could take the sump etc with it.

I've done it, and a few other people are the trap have as well. Just something to be mindful of.

Was managing 1.5 60ft's on a airport surface with 360rwkw/7800rpm launches.

using that page's calculator, a 6.8 1/8 mile ET converts to a 10.7 1/4 mile ET.

In order to run a 9.9 sec 1/4 mile Et you will need to run around 6.25-6.34 1/8 mile ET.

I would also suggest that you would need 450rwkw.

1.57 60' is very good for street rubber, however, some drag radials on the rear would improve this and therefore improve your 1/8th and 1/4 times.

R31, OP says he will use DR's on the rear only, so that should help gurad against front diff breakages. Although, it is not a guarrantee that it won't necessarily not happen.

btw, i'm not sure what the quickest 1/4 mile time using a stock r32/33 box is, but it may well be in the 9's...

This calculator is better than the one I have posted earlier:

http://www.wallaceracing.com/etcalc.php

Although the 60' and 1/4 MPH inputs might not apply accurately to AWD turbo cars (more NA and dedicted drag cars)

sky30, I would suggest that you will require approx. 430-350rwkw with a 1.5 60' with 6.25-6.3 1/8 mile ET to equate to a 9.9 sec 1/4 mile ET

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
