Hi All.
Does anyone have any tips or good links for setting up and launching a FWD car.
Currently the car has a road set chassis and interior.
it runs about 550bhp and trackday (R888) rather than drag tyres.
60ft at the moment is about 2.2sec crossing the line in 11.9 @ 126mph with tyres around 9psi and a burnout before launching.

Would improve launch but terminal speed would be down by 100mph lol

It's all about a stiff rear end, preventing weight transfer and aiding traction.

There is easily an improvement in there, just by running some dragslicks, the R888's have a solid side wall and give no help in traction and a burn out will never get enough heat into them.
Easily their is a 10 second ticket with the power your making.

Btw What car you you race?

I'm just support crew but its this we have started using.

Will be doing Thunder Road next weekend so 1/4 mile and standing mile.
Just dont want to go full drag spec with it as it is used as a road car and for track days too. So any little things like tyre pressures or technique tips rather than turn it to a bare shell etc hehe

I think the biggest improvement would be a set of drag slicks but not sure if the owner wants to stay on treaded tyres to keep it in road car classes.

1) forget road tyres you will break things, get some proper MT or M&H slicks believe it or not they are a lot easier on the car.

2) Get it corner weighted and set it up with as much weight over the front wheels as possible, hard rear medium fronts that quick to settle after the launch

3) Front traction bars work well and help compensate for poor suspension setup.

4) Some spin is good it means you wont break things

5) Don't be afraid to sit on the lights until you are ready to launch, its not a race (unless its eliminators) build your boost up then go.

Once you've mastered that with the right setup you should be able to get your 60' times down into 1.7's and 1.6's with further tweeks the 1.5x's and even 1.4x's thats what the fastest FWD cars in the UK currently do.

What car is it? Afraid I have no practical experience drag racing fwd cars only stuff I've read about.

I'd have thought you'd want to try and prevent weight shift on launch and try and prevent the rear squatting, so as to keep weight over the fronts.

I know a 1500-1600kg car with 550hp on sticky tyres should be looking at 1.7-1.9 60' times or better and would likely be well into the 10's if they could trap 126mph.

Maybe some crinkle wall drag slicks would help too.

Thinking about the squat again, maybe you could devise some sort of air assisted suspension to actively raise the rear of the car when launching, so as to try and generate more grip. No idea if it'd work though.

Watch out! He has found the drag racing forum!

RichardB is the man to listen to here, rumour has it he ran into the 9.5's this weekend in his FTO!

EDIT - Just seen Richard posted a thread below this one. Great run!
