Quarter Mile Calculator? Does it fit your ride?

[RAPID_BA]

http://robrobinette.com/et.htm

Admittingly it did pick my LS1 quarter mile ET almost exactly. Also a few other cars that I have checked are very very close.

Id like my charged 8 to run the time suggested.

[FPV GTHO]

It says mine should do 14.77

[T4ME]

I typed in 4000lbs and 480rwhp for a ET suggestion of 11.8 lol,I am already at 11.3 with a slipping trans and Darwin weather.

I recon a 10.8 is gettable so yeah its a bit off.

Turbo cars have a massive torque spread which the calculator doesn't account for.

[XR6_661]

Checked it against my old XR6s time...

Sport on, 15.4

My PB was a 15.448

~3700lbs, 200rwhp.

[335POWER]

Apparently 15.5 for mine

3756lbs, 199kw

[Angeldust]

its says my clubbie will do a 12.8

(weight is 3615 in pounds and 400 horsies @ fly)

if i recalculate using rwhp using 400hp@fly=300rwhp then its 13.35

[Mont5.0]

15.0 mine says.

[2011G6E]

Just for a giggle I tried my first car, a 1953 Austin A30.

1500 pounds, 30hp...

22 seconds...sounds a little optimistic to me from what I remember...

[The Yeti]

Lol I think it was optimistic for me
17:92

[AndyXR6T]

13.4
FLy Hp: 368hp
Lbs: 3858

I cant seem to print off my timeslip

[Benny D]

3860 lb .. i think thats right or abouts.
310 rwhp
comes up with 13.5

pb of 13.65.. so it is close

[Sprint]

says my escort will do 10.5 and my boss 12.5

not sure about the boss doing that.

[my67xr]

yeah, pretty close for me too
3600lbs
325rwhp
12.98 1/4

actual pb 13.08 @ 108mph

[Sprint]

say my 88hp motorbike will do 9.6

i doubt that

[RAPID_BA]

It says 11.44 for my xr8... Given the right conditions/tyres maybe

Make sure you add in the driver/riders weight too.

1kw = 1.34 hp

1kg = 2.2 pounds

[Sprint]

yeah the times certainly are optimal drive line setup times.

not bad tool though

[RAPID_BA]

Not really, my LS1 has stock diff gears, stock stall and it picked the right time. No doubt with gears and converter there is probably half a second to a full second difference.

Id call my setup less than optimal.

[T4ME]

Yeah but the 1st gear in the Holden 4spd is rather short and helps with take off somewhat.

This is the reason for hole shotting the Fords all these years with the 6cyls and some 8's.

This had me on the floor in stitches with laughter!

[Ford_The_Win]

3000lbs and 152hp = 16.5, that's about right.

yeah I got it to come out with 16.1 for mine, which is quite close seeing as I got 15.5 and my GF got 16.6 in hers, which is the same but auto.

A standard 3.8 V6 from Holden only out performed the 4.0 I6 because of the shorter first gear in the transmission,the BTR is very tall but this is where economy comes into play.

The 5.0ltr Holden motor was the same scenario to the E series Windsor 5.0.....the shorter first gear in the trans getting the torque going sooner.

Why do you think a ZF 6spd BF 6 or 8 beats the same powered BA 6 or 8?

from my testing of torque converters the smaller GMH v6 converter has 40rpm less out put speed from the input speed.While the larger Ford converter has only 13rpm less output speed than the input.Though i have not tested one, the ZF has a smaller converter similer size to the v6 GMH converter so i'd say it also has around 40 rpm less out put speed as well. It is like a higher gear except that it is in the fluid coupling of the converter.Though I have been able to get the Ford converter to slash a 10th in the 60' with standard stall. I can also get more out of the GMH v6 converter as well.VStrong Super Charged Torque Converters (TM)

It's not the gear ratio that makes it short is what i'm trying to say, it's the converter size.If i was able to upload some pic's i'd show you some dyno comparisons that show it.A while ago I made up a extra modified GMHv6 converter to fit the Btr trans for a BA fitted and Tested at Heinrich performance and tuning in one of his cars. it come on eariler with extra 20kw right through the rev range but with slower top end speed.T4ME has the first stock stall Super Charged Torque Converter of mine in his BA and has improved his track times considerably,,as well as giving a bit better fuel economy around town!VStrong Super Charged Torque Converters (TM)

3550lbs
Dyno showed 300rwkw, but convertor is soaking most of it.

this calc says mine will do 11.4 but its done 10.9xs@121/125mph

[needfordspeed]

Said 11.2 for me but i've gone 10.6

Said my clubbie should do 12.7 which is probably about right. Maybe it works better for NA cars

[comagutsa]

how much does a ute weight???
i used 3900lb x 394rwhp = 12.5

i would be happy with that

[naughts]

Nope.. Said 11.8, but have gone 10.91

[Trevor 57]

Ours is a circuit racing XE it reckons 11.1

2800lbs (it weighs 1400kgs) and 400 RWHP
