analyze drag time slips

[Pappu1]

i know a bit on it but not a whole lot lol

so looking at ppl adv on how to break it down and what are the places car is slowing and faster etc...

i can post up the slip if u want

just some adv on what improvements gotta be made

trying to better the times obviously and trying to find the cars weak momnets and also driver ability lol 8)

[Pappu1]

ok here is the 3 runs

the first and last are identicle and the middle one is whacky lol

adv and opinions plz (hopefully to get better on next round)

runs were on a semi-hot day

(carjam states the weight of the car - v7 sti - as 1700kg... .. how true are they? cos with driver and bit sounds thats like 1800+kg )

[pedro]

v7 STI weighs around 1430 kilos...

[Guest]

Carjams weights are up the shit.

Evo 1-3 are around 1200kg iirc GC lightly heavier...I think.

[Pappu1]

Have to run v7 17 as brembo so no 16

Why will a 16 make it quicker tho?? Will it really?

And yea unsure on weight so just going by carjam unless anyone knows better??

Bump for some analysis....

Took mine over the weigh bridge at work and cam e up with 1480kg my old gc8 was 1250kg

Looks like you\'re a pretty good driver. Excellent 60ft and 1/8th is very low given the low trap speed from car with not huge power, I\'m guessing at around 220/230kw?

yea its round the 230kw mark

60ft was 1.76-1.8

i was thinking a better 60ft maybe 1.65-1.70 will net a better ET or drop in 11sec....?

will tune up the power round another 10kw or so before next round

is the car doing better at low end ot top end (basd on time slips)

im not too certain how to work that out like some ppl do...

[sultan]

First half of the track is best. Every .1 off 60ft is .2 off et, so yes its possible. Will be doing very well if you manage it with only 230

based on slips u reakon need more low end or more top end go?

damm v7\'s are so heavy but the idea is to pull 11 with full street trim

[sultan]

Do you mean in your power band? I would say power in lower rpm of the power band is most crucial the first half of the track where as second half is all about peak power. Increasing your peak power will probably yield the biggest result for you

I wouldn\'t call a v7 a heavy car

ok sweet so top end it is then...

will basically be tweaking cams and get some top end for a bit more trapspeed and hopefully drop ET

v7 is rather heavy compared to a gc8

something along the lines of 200-250kg i read on multiple forums

never weighed any back to back so going by the interwebs...

1430? wow thats gc8 material...

1430kg is factory kerb weight.

No GC8 was ever that fat unless it was full of pies.

Factory kerb weights for STi v5/6 coupe/saloon/wagon 1260/1270/1310kg.

try and get more top end power as this is where you will be most of the time, even getting off the line you still going to be in the 6k mark but other then that look really good, slicks will get you in the 11s
