Loved the formula cars and the bad ass evo's! Wish there was an event around here like this.

 

+1 I would love to participate.

 

+2, i would love something like that close by.

 

looks like fun, i do have to ask tho why do like half the cars sound like they run like complete shit & are breaking up?


Ps: send me some parts

 

Because some of them just did xD xD

especially that green EG hatch did sound terrible


that Peugeot 206 (gold one) was really slow and stalled everytime the revs dropped below a certain point.....but some race cars just sound like shit even if they are fine.

 

Word yea it was mostly just those like first 3 evo's sounded like they were just detonating the whole time.
wish they had something like this around here!

 

its called anti-lag

 

While driving? lol
I know of anti lag when launching...not driving.

 

yup especially while driving:

Today's WRC cars also use anti-lag systems which feed air directly to the exhaust system. The reason is that these systems are more refined, more effective with advanced computer control, and also quieter. Today this kind of system has reached such a refinement that it’s even possible to use the system in a road car. A recent example is the Prodrive P2 prototype. The system works by bypassing charge air directly to the exhaust manifold which acts as a combustor when fuel rich exhaust from the engine meets up with the fresh air from the bypass. This will provide a continuous combustion limited to the exhaust manifold which significantly reduces the heat and pressure loads on the engine and turbocharger. With the latest anti-lag systems the bypass valve can not only be opened or closed but it can actually control the flow of air to the exhaust manifold very accurately. The turbocharger is fitted with a turbo speed sensor and the engine management system has a map based on throttle position and car speed which is used to find a suitable turbocharger speed and boost pressure for every condition. When the engine alone can’t provide enough exhaust energy to reach the turbo speed/boost demanded by the management system, the bypass valve opens and exhaust manifold combustion begins. This not only reduces turbo lag, but it also allows boost to be produced at very low engine speeds where boost was previously limited by compressor surge or exhaust energy. With relatively high boost at low speeds, this makes the low end torque superior even to large naturally aspirated engines. The system is quite loud and is banned on some rallies because of the noise it produces.
