Does anybody do this? Ive tried it a few times, but not realy used it for overtaking yet.
What I mean is supposing your in second at 2500rpm and want to accelerate quick 2500rpm, you cant realy change to first to bring up the revs and boost, ive been trying braking with my left foot and flooring it at the same time, to get the boost up, then let go of the brakes, and your gone!

Hard to explain, is is a widely used, or am I talking rubbish

remind me never to buy a car off you...

Rob,
Does it work though? I can see the logic, but boost needs enough revs to spin the turbo, and braking means loosing momentum, never tried it, I might do, once!

rob oneill

Im undecided as to if it works or not, was just wondering if this was something that people do, think it would need lots of practice to get right, and like blue haze says, cant be good for the car

If you balance the brakes and the throttle you can maintain road speed. Takes a lot of practice.

However, left foot braking this way will increase the load on the engine, bit like suddenly driving up a steep hill. This will cause the boost to rise. Releasing the brakes then means you are on boost, but not necessariy on full boost (but you get there much quicker).

Used to use this technique to great effect against tailgating BMWs. You brake, they brake, you shoot off into the distance.

That would be funny!

Its a well known technique, used to be used in the old days when cars had big lag, not a problem in a std road car these days IMHO.

Would it not be easier to dip the clutch and rev the engine to get it onto boost.

cars dont boost much when there not under load, which is why you dont get much boost reving a parked car up

I do this all the time in the rally car , I used to do it a lot in my old very laggy Escort cosworth road car , work really well on roundabouts , throttle planted and hold it back on the brakes it takes a lot of practice to get the ballance right if your on the limit , as soon as your off the roundabout , off the brakes and its like being catapulted off , dont try this with cars around you though !

It's the method of checking boost level described in the Sierra Cosworth workshop manual! Hold car with brakes while on full throttle in 4th If my memory serves me.

I used to do it in my old Renault 5 GT to overtake.... light pressure on brake whilst increasing throttle, then release brake and shoot past. It did get a bit hairy on a couple of occasions when I couldn't overtake and had to slow down.... feet and brain all confused, and nearly went into the back of the car I was overtaking!!

It worked on the GT because of the terrible lag, but I wouldn't have thought it would make any noticable difference in a new Scooby.... being in the right gear makes the most difference.

Thanks Micky Didnt know that mate,

Good advice as I'm sure the owners wouldn't let you even if you asked nicely.

The only thing that i can think thats going to really be taking the strain is the brakes-the gearbox should be able to cope with the load as its not taking any shock as it would when releasing the clutch quickly.
Just buy yourself a spare set of brake pads/disks,as youre probably going to get through them pretty swiftly

Im sure he meant 'dont try this whilst other people are driving next to you'


I have tried this in various turbo cars and it does work,but as suggested,it can be dangerous and it will wear down the brakes quickly.

It's a widely used technique in RACING turbo cars. But those cars usually come with a big spares package

Be careful if you need to brake after using this technique -- if your brakes get too hot they are more likely to fade!
