now that my s2 is in the state of taking some abuse, just wanted to know peoples techniques and methods on how they launch of at the lights etc. i intend to take it easy in first and second (upto 3k-4k revs) then shift to third and gradually press the pedal to 6k-6.5k revs) in each gear after.
in most cases ive herd people just flooring it straight in all gears after gear change, but i find that by doing this petrol is wasted and not much power gained oh mayb i havent got the technique right yet

EDIT: my main aim is to get 210hp on the road like it did on the rollers

Your wanting to know the technique to get the best standing start and your worried about wasting petrol

T28 RST

If you take it easy 1st + 2nd then give it everything in the rest of the gears the car your racing will be long gone

[quote="T28 RST"] suppose i deserved that

BlueFiesta85

but that way i save my gearbox from blowing early in its life

T28 RST

If you dont do it all the time you will be ok, just hope the clutch will stand up to it

BlueFiesta85

thats another issue im worried bout, each time the clutch goes got to fork out 300 bloody quid

T28 RST

If you have a paddle clutch it will take a good beating and a good few standing starts

BlueFiesta85

problem with the paddles is that there absolutley crap in the long lasting traffic queues

T28 RST

Only way to go if your wanting to race off the traffic lights

Well, I tend to rev to about 3500 - 4000, then declutch only a little bit to apply power to the drivetrain. You know, there's always a bit of play in the gearbox, diff, shafts, etc. And I'd like to put everything in a "load situation" before really launching to avoid any big jerks and nasty side effects like torn engine mounts, broken drive shafts, etc.

Shortly before I declutch completely (which is done carefully but quickly) I lift off the throttle a bit. As soon as the clutch bites I give it beans again. While avoiding excessive wheelspin I try to go to 2nd gear quickly and after that make the best out of the available rev range.

as above.


in 1st and 2nd gear, keep on the border of spin and power,
i find it best to get into 2nd as soon as you can.


ps, lower your tyre pressures to 17- 20 psi, and give them a slight spin before the line, to get rid of old tread and gravel etc etc.

and then get out your car and spray wax oil over your oponents tyres

i was talking about 1/4 mile sprinting.

where was the 210hp RR'd at?

hmmm, i thought your more likely to kill a gear box in third any way due to tourque multiplication ????

i have noticed figures tend to come out between 10 and 15 horsepower over when at powers rollers compared to most others.

Treat yourself to an omex rev limiter mate and launch control! Bought mine on ebay for £80, not only does it save you from over revving your engine , also gives you a second limiter ideal for traffic lights and santa pod launches. I set my launch limiter to 2500rpm and when the lights go green let off the limiter and an off you with hardly any wheel spin! It' works really well with a paddle clutch and would take only 30mins to wire in! Dead easy!!

im selling one for £90 not been fitted but would match the ebay price

It should still be quick off the lights with the right driver... to a certain degree. With a decent clutch

the good clutches seem to introduce the issue of broken gearboxes lool
