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.

[The Yeti]

Lol I think it was optimistic for me
17:92

[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...

[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.

[Psi-Pop]

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

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.

[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

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?

[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

[Sprint]

xe@1400kg, is there much left of the car?

[FPV GTHO]

XE's aren't that heavy. I've found figures, probably for a 6, of 1320kg. Make it a V8 (+100kg), roll cage and then some weight reduction and it makes sense.

1400kg is almost 3100lbs though.
