run me car today on 1/4 mile again

[scooby555]

went and run me car now i have had the rica done best time was
15.176
97.80 mph
60ft 2.639

is that about right for my car with them mods. but still can not make me mind up if the car is any faster now mind u dont the rica come in more on mid range ?

¼ mile racing and times is mostly down to the start you get, and looking at the 60ft, yes its about right, get your 60ft down to 2.3 or less and your looking at 14.5 seconds or less and a trap speed of 100mph+

I got a 14.2 earlier in the year with a 99mph trap but the 60ft was 2.310

[scooby555]

is hard to get the start right that time was done with the dstc on to did think it may be slower with that on.

[volvotuning]

You have to turn DSTC off when doing the 1/4 mile. It makes the car slower cos it cuts the engine power. My D5 is a pain when the STC comes in cos the car just bogs down when the engine power is reduced, and there is a delay before you get the power back too. So if I want a quick getaway from a standstill I always turn it off.

did have 3 runs with it off got 15.3 then but no grip off the starts.

This is where you need to practice technique, because you can launch must faster with the DSTC off if you learn how to do it. But it does take a lot of practice to do this consistently.

Put it this way, Spesh can consistently get at least 1.0 secs quicker times than I can. Now, the power of the car doesn't change! The only variable is the driver.

yer have to get more practice. was the same with my old scooby was doing hi 13 when i had it in the end got down to 12.8 just down to the starts.

what time about shud i get with the rica and itg hi 14sec ish ?

[volvotuning]

Low 14s realistically, but high 13s is possible. Assuming that there is nowt wrong with the car since it left us!!!

Have you got the 280 or 300 map? What madel T5 is it?

x

[scooby555]

300 map t5 se s60

[dave]

i thought the standard s60 t5 could do 15 secs 1/4 miles?

your 60ft doesnt seem to bad, i think if you got 2.5secs, your be doing well.

if your car has the 300 upgrade, it should easyly pull below 15 sec runs, even with a poor start, something is amis??

I dont think it is Dave, its all in the start and whilst a 2.6 sec 60ft isnt bad it makes a huge difference to the trap time and speed

[dave]

yes, but if you make a 2.3 sec 60ft, take that of 15.1 = 14.8secs, which still seems alittle slow for 300bhp, i thought it should be low 14's?

[Justin]

It dont quite work like that Dave...sorry to dissapoint

[Andrew]

You also have to remember the weight. 300bhp is a hell of a lot on a fibre glass covered car

[volvotuning]

Dave,

Seriously, it's much much harder than you think. I am of course assuming that you haven't tried it yet. If so, then pop down to a drag strip and see for yourself. It really is much harder than most people realise. Some people have got their best times and don't even know how they did it!!! Cov Crew springs to mind here

You need to take the following into consideration -

1. Track condition
2. Ambient conditions
3. Engine Output
4. Tyre type
5. Tyre pressure
6. Launch technique
7. Gear change technique
8. Number of gear changes
9. Other drag losses
10. Weight

And a whole load more things.

how does it work then?

i fully understand where your coming from mate

but ive had most of the sporty cars ive owned at the 1/4mile, ive allways managed to pull the book time for them, didnt worry about things u have mentioned, just got it in and drove as fast as i could, last car i took up was my fiat coupe, managed 14.5@100mph, which is the book time for it.
