Yeah your times seem about right. My sti ran 13.3 in Albuquerque, NM. Pretty high elevation. Just a catback.

When that time was done i was running a sv21 camry gearbox which is an open differential so it frags one wheel. The tyres were 205/50 r15's naykangs (cheap crap) and i managed to get a 2.2s 60 foot time. The track is closed for winter here and in a month or two im gonna go down again because i got some 17inch rims now with 215/45 kumo tyres which should help me crack a high 12 second pass... hopefully :D


No, your times really DONT add up.

A 2.2 60 ft is pretty terrible, and a trap at 106.81mph is very respectable, but not fast enough in my opinion to net a 13.0 with a 2.2 60 foot!

My best 60ft is a 2.2, and I've trapped 103, yet ET was still a low 14.

I'm running an mr2 turbo gear box, with a TRD LSD (2.0) and some 225-40-17 cheapo tires. I'm probably putting down around 230 Front Wheel HP....

They do add up for me.
He obviously has more power so more traction issues at the start since there's no LSD. Once the grip is found he takes back what he has lost in the first 60ft.[/quote]
When in doubt - increase boost.

A 13.0 flat is straight moving, looking at all the SRT-4 times, my times, other FWD times... It doesnt make sense at all.

He needs another 4 mph trap IMHO to make up that much time.

hahahahha, well you have to believe because i thats what i did. i've got the 1/4 mile slip that shows a 2.2 60 foot time with 13.0 @ 178km/hr but i dont know how to post pictures on this site (apparently i need to host the image or something :shrug: )

178km\h is not 106.8mph... it`s 111,4mph...

(111,4x1.6= 178km\h

(111,4x1.6= 178km\h

1km/hr = 0.621371192mph (to get 178km/hr mutiply both sides by 178)
so 178km/hr = 110.6040 mph :D

if you just times 178 by .6 then you get your 106.8mph, but rounding only to .6 gives an inaccurate answer

Well at least you were right about the extra 4 mph that i needed :)

OR you can use the ET method.........

hp=weight/(ET/5.825)raised to the third power............

Plugging those numbers in, we get 268 hp.

Works for me..........did you forget to raise the product of the division of the ET by 5.825 to the third power before you divided that number into the weight? i.e. 13/5.825=2.231759656, this number cubed is 11.11583949 THEN you divide the weight (I forget the number, but 2975 sticks in my head) by this number............
2795/11.11583949=276.6361063

Thanks...........it really applies to the topic "highest speed in your All-Trac" though. I remember doing it well. Some people say that I photo shopped it, but it's real. There is even a video taken with a friend in the car somwhere on alltrac.net (probably in this forum) that shows me running from about 80mph up to 160 with an engine missing out badly(fouled spark plugs), before I ran up traffic's ass and had to stop.
