I was checking modular fords website and checking out the calculation deal they have with estimating all different scenarios...idk how close these really are to being correct...because I would put it my MPH for my 1/8 mile and the estimated outcome seems to be .4 faster then what i did...then esp. when i entered my 75mph trap with my 9.9 it shows 9.2 instead....i trapped 72 and 71 at 10.2 but it shows 9.8 instead....i mean i know its estimated but maybe its just my take off that sucks but I start moving a lil quicker towards the 1/8

check it here

I even put my MPH trap of 91mph and estimates 14.9 but i was running 15.4...but a lot of cars i see running the same mph at the track match up with 14.9s and 14.8s...so i guess it is accurate and my 60' hurts me the most but im still trapping decent

or maybe it is on a car with a differential that locks and spins both tires... and on DR's??

better track conditions, different altitude, different temps and climates... to many variables

[02ponypackage]

i know that...but most cars running high 14s such as 14.8-.9 are trapping 91-93mph.....here in FL at OSW...so that 60' is really killing....variables i know but still it is pretty accurate from the cars ive seen....its not taking into consideration a really sh*tty start...so maybe this is the reason why i can run with cars on the street from a roll that trap the same thing but have a lot better start from me...but my mph time ends up being the same

sounds like you need to fix your rear end and get some tires then

yea, these are generally pretty accurate but cannot account for every variable (such as wheel spin)

1/4 times i use (pretty accurate..i cant find to many if any that are too off.)

1/8 to 1/4....VERY accurate. ive tested lots of 9 second 1/4 slips and 15second slips

dont forget factors such as wind, temperature, shifting. there are alot of things that dont hold fast to those calculations. if you should get close but those are estimating 'perfect' runs.

damm so i guess the 1/8 to 1/4 time from a run in the florida's summer being right on the money and another compared run to a car in TN another in GA, another in MA all being on the money....


temp from those states and humidity are all very diff


and who would count a timeslip where they ran through the 1/8 perfect and missed 3rd......? and ran a 16 where if they didnt miss they'd get a 14


what you said is pretty...not wrong but OFF

[itschristorres8]

oh and your sig is OFF as well seeing that most mustangs turbo'd see more torque then hp...

and any civic turbo'd can take a bolt on v6 if that wat you have...

unless the civic is on like 5psi

[CobraR]

you coulda just said i was wrong and not been an about it. and whos cars about what my sig says, it a joke and a funny saying so just chill the eff out.

[itschristorres8]

k your wrong

[stanged out]

i didnt wanna make a whole new topic about this so i just thought i put my question under here..... is there a big difference performance wise between 18 inch and 17inch rims , because i currently have 18's and wanted to do nitrous and some other stuff , about how much would it affect my et

[Onemanzu]

actually if you can get your hand on a pair of 15's for track use that would be your best bet... just saying

but 18 to 17... isn't that noticable...
18-15 is

[02ponypackage]

well like chris said...with the FL cars this is pretty on point...now ive seen cars go 13s at 86mph thats because they can make a pass a lot quicker then 13s and obvioulsy just got off of it...but seeing i trap they way i do...is the same reason why those cars running 14.9s on the street have a problem with beating me

[BillyShope]

I have quarter and eighth spreadsheets at my site, but I'm careful to point out that the ET results are for comparison ONLY.

Speed results are pretty good, though.
