I disconnected the ABS on the race car by litterally keeping all the existing lines and using T pieces to link out the ABS.

Not sure waht the next question was, whats the clutch slipper

A slipper clutch is an electronically controlled valve that allows you to dump the clutch and as long as you have ahold of the button it will slip the clutch/release the clutch pedal at certain speed, which is adjustable on the valve.

Then once you have launched the car you release the button which turns of the clutch slipper and also the clutch to travel as normal when you are changing through the rest of the gears

So special for drag racing to stop the wheel spin then
Or am I wrong ?

Special for drag racing to stop leaving a collection of parts on the starting line

Slipping the clutch allows you to keep your foot on the gas, flat to the floor, and you are modulating the rate at which power is applied through the drive train via the clutch. If you are wanting to be consistent then having the clutch slip through mechanical control rather than your own foot means you can dial it in for how grippy or slick the track is.

Clutches will be burnt out faulty quickly but that's better than a smashed gear box, smashed diff or smashed drive shafts

There is a company that makes a weighted clutch that slips, but as the weights are thrown out due to it spinning the clutch then bites harder

I also need a line lock on the front brakes so I can do burnouts far easier

Sounds clever stuff

I think it is too.

Easiest way to slip the clutch is just use your foot but to run consistent iv got to try control things.

Achieving a 9 seconds pass is great but if I then run slower all the time because I'm not repeating the same formula whilst driving its just pointless.

I'd still run that if I had an expensive gear box because of consistency but you could be more aggressive with it....until the diff brakes

I'm quite looking forward to learning how to get all these things working together, suspension, tyres, gear box, and clutch.

A lot of people think drag racing is easy as you are just driving in a straight line but it just isn't there's the exact same amount of setup and tuning involved driving in a straight line as there is driving around a track.... That is unless you pull the front wheels off the ground when you launch a drag car, then you have no steering at all

Just ordered some 3/16 copper brake line, brake line flaring kit and 2 x T pieces

Should sort out the clutch lines I need to run inside the car for the slipper, a line to run for the line lock for the front wheels and get the brakes all connected back up.

Not an exciting job to do, but needs doing nonetheless

I have a few friends from the drag racing scene, mainly fwd corsa stuff but Christ they’re quick.

I went to shakeys a few times when I was into yank tanks, never competed tho.

Oh it’s certainly more than driving in a straight line. I think most competitors wish it was that easy.

I used to think fwd drag cars were a joke.... Until I saw them running 8s with mph that should be of a 7 second car! The Hondas that run in the fwd are making huge power, think there's a couple making 1200hp

Torque steer must be horrendous even with the best automatic torque biasing diffs

Iv no idea what they do but it must be magic stuff to make it go straight. Impressive power, speed and times but it's still fwd drag car

No one has ever seen a fwd drag car do a wheelie
