Why do the fast cars at TOTB pop and bang?

**Oakey22** · 01-08-2006 14:30

what causes this to happen? you know when they nail it they pop and bang.

**chip** · 01-08-2006 14:32

Because they are essentially "misfiring" as part of a launch or antilag sequence.

**Oakey22** · 01-08-2006 14:33

oh rite, but wouldnt that be a danger to the engine?

**chip** · 01-08-2006 14:34

Yes it IS a danger to the engine, but a managed one.

Over revving the engine wheelspinning and hitting the limiter also does it no good though.

antilag is PARTICUARLY nasty to turbos though.

**Scoobler** · 01-08-2006 14:34

Isn't the idea of it, so the explosion causing the bang happens before the turbo, in essence causing it to spool faster / more getting the boost up higher and faster?

**chip** · 01-08-2006 14:37

The idea of it is mainly to make the engine far less effiecient by retarding the timing massively so the turbo can still spin without the engine over revving due to the amount of air its consuming.

its all very nasty when you have anti lag going though cause the explosion happens in the head and manifold and causes massive amounts of heat around the valves/head/turbo

**chip** · 01-08-2006 14:37

Ps

Depends on how aggressive it is though, there are many differnet "levels" of antilag.

Potential need for deep pockets and a friendly bank manager then!

that wee civic with the fat slicks was a prime example. it popped and banged all the way up the track. thought it was the traction control doinits job

Antilag is what your hearing.....the map has shed loads of advance on idle creating higher cylinder pressures and bringing the turbo on "spoolup" even though the car ain't moved.... something like that anyway....lmao

thats also why you get pops and bangs...

Im wrong then lmao - thought it were advanced

lmao

Deep wallets for new turbo's as well

REALLY not good for GT turbo range with thin shafts etc....

Only have to watch that to see that it kills things, violent lmao

**Scoobler** · 01-08-2006 14:50

My mate has the anti-lag on his Nova Turbo, I would love to see/hear what passers by think when they hear it going off lmao

bet the locals love himlmao

**rodgerq** · 01-08-2006 14:53

sounds a bit of a beast that thing

**Oakey22** · 01-08-2006 14:54

lol, so antilag stops lag on the turbo? i dont know a lot about turbo's

**rodgerq** · 01-08-2006 14:55

yip boost gauge reading positive pressure with the car stood still

I think some of that was down to some kind of primitive traction control system tbh. Didn't work though lmao lmao they might aswell have tried to drag race the car on ice for all the good it did.

agreed it didnt seem effective at all

Optimum power on that surface for a FWD car seemed to be about 400bhp really!

**Jordan** · 01-08-2006 16:07

hi, dont know if this means anything, or my engine isnt set up properly,
but iv got a nove gsi C16se and when i toe it and then change gear, it pops and bangs.
it was like this when i got it so dont know what the engines got done to it.
but it dose go quite well for a 1.6 and iv had a crapply times 0-60 in about 7. any idears lads.
is it time for a rolling road and a set up or should i not fix whats not broke.
