Quarter Mile Calculator? Does it fit your ride?

[phat_stak_tipa]

With me in the car weighed in at 4012 pounds has made 212rwhp and i ran 14.91 it says that i should run 15.4 so its abit off.

No, all doors are gutted, plastic side windows, all dash and flooring (including deadner) gone, all interior material, seats gone, jsut a race seat, but it does have one heavy mutha-****** clevo in the front - LOL and my son tells me it is 425hp at the last dyno

[In Focus]

2650 pounds, 180 hp = 15.047. Fairly accurate.

I haven't done a 1/4 mile myself, but Motor Magazine tested a Fabia RS at 14.97 during its Bang For Your Buck issue.

[dieseltrain79]

No where near it ...

Says 12.9 . The hundred odd 11.8 second slips say otherwise ;)

[The Monty]

Says 13.6 for me, not including driver, fuel, three baby seats, a toolbox and maccas, and I ran a 13.0.

[Sprint]

Interesting so many say its on the low side when i think its on the high side.

Its only going on power to weight, so many other factors... driver,weather,setup,road,luck..

[SpoolMan]

says mine will do 11.23, has run 10.81.

[XR8menace]

Says mine should do a 10.84 @ 4000lbs 620rwhp and I did a 10.96 in a manual.

[T4ME]

It just doesn't factor in the huge torque spread from a turbo car.
Seems to be about 4-5 tenths out for a few.

[prasac]

they take way too much into account for the shift. every shift @ 2/10ths, found it works best if u just put in 1 shift, instead of say 3 or 4.

this description sounds like a v8 supercar

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)

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

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)

[B-series N/A 6]

Wow mine needs a tune badly.

[fridaykiller19]

it says 15.4 for my fg xr6 even though my best is 14.2 so way off for me

[Mont5.0]

with my new found power it is saying 12.9 was pretty close before,lets see how close it will be next time i run.

[Starlightblue]

close for me - it says 10.505 and car has run a 10.46

[XR8menace]

Escort with a cleveland?! That sounds like it would be fun!!

Manual or Auto?

[Starlightblue]

yeah it is a bit of fun.

its a reverse patern c4 with 4'500 stall.trans brake etc
