Launching A T56 Manual

[01txr]

There will be different ways that suit each car.

Stock v's tuned

Fibre clutch ceramic clutch

Type of tyres

Etc eta

I used to half clutch, let it slip a little till it moved then drop full nail.

But after fitting to4z setup it just boost so quick it is so easy to fry the

Clutch.

Best possible way is to fit billet driveshafts, slicks and just dump it and

Hope nothing else breaks.

Just take it out on a back road some where and have a practice 3000-3500 is the sweet spot any less you'll bog down any more wheel spin haha or fry clutch like I did after 3 or 4 attempts stating the obvious you want TC off haha

Practice on old back road will be totally different to on the strip but will help you get a feel of what you need to do.

May only be 1500 on street before it breaks out in wheel spin but on track at those

Revs it will stall.

If using regular street rubber you should be careful dropping pressure as they are

Designed to run at a certain pressure, effects in doing so could lead to

Steel belt damage, car getting unstable under brakes.

I have experimented with lowering slightly max 5psi to raising 5 psi

And found the street tyres to bite harder with more pressure.

Think about low pressure, it will cause the tyre to get out of shape

And unless it's designed to ripple the sidewalls it will be doing damage.

A drag tyre is designed to ripple it's sidewalls and make full contact with

The track surface.

A street tyre with low pressure will concave it's tread & it will have a

smaller percentage of it's contact patch making contact meaning less traction.

If you run at recommended pressure it will hold it's shape and plant it's

Tread.

As I mentioned I have tried at 5psi more and it did work but don't recommend

Doing so as you don't want to have them over pressured in a high load

Situation.

Maybe some street tyres may respond differently but if you choose to

To run other than recommended pressure becareful, at least contact

Your tyre manufacturer and find out what he recommends.

Want a grippy tyre that works with low pressure buy street drag tyres

Or slicks.

Be prepared to break drive shafts and destroy standard clutches.

If your car is stock you will find if you do drop the clutch it's torque restriction may

Cause it to bog down where as driving of the line will give a better result.

Another thing don't bother with a big skid as all you will do is raise your ic temps if it is

Standard ic as well street tyres don't like to much heat.

A good option is to get some dry ice and put in air box Pre filter.

Helps especially on your followering run, also open your bonnet while lining up to get rid

Of excessive engine bay heat, make sure you close it for your run Doh.

Have over half tank fuel to prevent fuel surge it you don't have a surge tank set up.

Take jack, spare and any other loose object out.

Pending your suspension set up you may also have to experiment launching it,

Eg A everyday street 351w Auto TD Cortina I built over 5y ago, to get it to hook up

on the street I had to jab the throttle to half way so the rear squatted get off it

Then full nail it, I was putting 2 plus car lengths on wrx's 1st gear not bad for

Stock on dedicated LPG.

On the track could just nail it.

So many variables with every car, even more so once you start changing parts.

Also pending your reaction times you maybe have to experiment with

The Christmas tree (drag lights)

Try launching at 2nd last yellow as by time your brain tells your foot

To lift and the clutch engages and car finally starts to move it's green.

Here at willowbank you aim for a 0.400 reaction time, any quicker and

You red light, if a lot slower you will be left sitting.

I was getting with my T anywhere between .6 to .8 with the rare

Bad launch.

That's probably around the average for most, except the pro's doing

.4 to .5's.

I was launching on the last yellow, but back when I first tried I found

Myself sitting at the lights, I went up to the guy I ran and said what's

The go you left way before me and he explain it all to me.

Just in that 1/2sec launch saw him get approx 2 car head start, very

Hard to win from there.

Wow! cheers heaps boys :D really appreciate the input you have all given! I shall have a go with running with these suggestions and see what best suites me :D thanks again boys!
