Yeh a couple of times In my dreams

[polly_x]

I launch my Westy in 2nd using launch control but thats only 2wd obviously. Works fine from a launch perspective but the timing gear proved nothing gained.

showoff lol

really, wasnt any faster then

Nope. It also wasnt any slower though. Did countless launches using launch control from 1st and a couple from second and they were all within about .2 of a second to 60 and about .5 to 100. My car also has a very long first gear reaching almost 70 which also helps.

I could also match the time just about with a manual launch but then you only get a perfect 1 every few attempts where with the launch control it monitors everything and does it for you and its the same every time!!!! (cheating I know)

[mk3cosworth]

cheers

[james kiely]

what launching system are you using mate?

cheers james

[Dan@Rapid-Ford]

funny, I was thinking the same thing yesterday

I was going to try it the next time I took the car out. Then probably change the clutch

I tried it with my saph once, just bogged down to be honest wenny
although your might be different due to a bit more power (lol) and a lot less weight

And the fact my launch control product is designed to bring the turbo on boost so you have a GT30 with 25psi at your disposal when you release the clutch.

now stu, hows it doing,

Hello Fella,
Going ok actually, we have a peak of 42psi and holding onto around 38 all the way. Nothing to report other than what Will has discussed with you. Going to try another couple of launch points and retard algorithms and ultimately give you a couple of chips to try that may suit different road surfaces for you if the lower launch points bog a little.

[mk3cosworth]

nice to hear, sounded well when i was speaking to wil, hopefully see you tomorrow with a happy face lol

Actually, Will is just working on your bill. Im sure I will see you tomorrow though so 1 out of 2 isnt bad surely?

[mk3cosworth]

ha ha, hey behave im allready nervous

Erm, I wasnt joking, I really am doing that.

Dont worry, they are free, im just trying to perfect your package for various road surfaces.


Edited to say:
Dammit, just realised you meant the bill not the launch control.

for me.

[dojj]

what ratio is the diff mate?

i know we were trying this way back with the 3.9 diffs rather than the 3.6's and there was very little to choose between them really as you couldn't rally change fast enough from 1st to 2nd to make sure of the extra acceleration, but, at the same time, you lost a bit pulling away in 2nd but it was a nice big rush of power

if you can hit 60 in 2nd though it might be worth a few tries to get the right take off, but if it's 4wd them 1st gear launching ftw

how quickly can it reach 100mph?

Think the best I did was 6.9 to 100 at Brunters.

It only had low 400's BHP then. Should have a 100 horses more now and also better grip but not had it timed as of yet.

[Porkie]

Its going to be SOOOOOOOOOOOO much faster!

not that you will ever drive it you fanny!

[Glenny Boy]

I hope Wenny can get the car into the low 10s when all this work is done.

3.6, by the sounds of it, it will be 1st gear.

maybe a ffd sequentil with drop off handbrake for the future

[mk3cosworth]

what he needs now is a change over board and a switch on the dash to shift between strategies

[turnover]

you might possibly break in the 10s at york good luck mate as you were trying so hard a cf show,but shows its reliable

Whatever turbo, 42 psi should be nippy!

[mk3cosworth]

its at 40psi now and holds 37, its a roller bearing t4

Buy a bigger boost gauge.
