I've got a fully de-catted MY01 and was wondering what id the best way to force it to pop and bang? My DV is still standard by the way, but I am lending a VTA for a track day soon

Steve

 

over fuel the car...it will bang and pop all day...not to healthy i would have thought.....

FSE boost vavle will also help..and of course a VTA blow off valve..


all the best

Oh Steve. You need to get out more I think mine does it from time to time.

 

I'm running a full decat with vta and get pops and bangs on downshift but only normally at low speed.

Gordo

 

Get the engine really warm, then just switch off the ignition for a few seconds and back on again as you drive down the road in gear. This can give spectacular bangs and may even blow your exhaust. Pretty stupid thing to do but whatever turns you on. Suggest you only turn the key back one click. More than this and the steering lock comes on, there will be another bang as you hit whatever is in your path and a loud rip as you fill your pants.

Enjoy your sound effects.

 

Rice Crispies - Snap, crackle and pop

My car pops and bangs. I am running a full decat, Forge D/V and K+N Ind Kit.

 

Or!

You can get a tek3, get Pat to map it, then ask for pops and bangs he will then pull the timing out on the run down and then, hey presto! all you need to do then is gently touch the throttle for a whole load of fireworks in the exhaust

it especially works well with a loud exhaust

 

Get your self a decent blow off valve preferbley one that you can change the settings on. ho and also get rid of those cats it makes a big differance, just one thing keep and eye on the flames mine been known to blow some pretty long ones out when gearing down.

 

full deacat, firestorm backbox and a va dump valve works for me

 

Harvey,

while your suggestion would work extremely well on a carburetted car, on a Turbocharged Impreza, the moment the power is removed from the ECU, the injectors will cease firing and no more fuel will be delivered, so the exhaust will not fill up with a good air/fuel mix. There will, of course, be some residual fuel from where the manifold has been wetted, so you may still get a small pop, but not in the same order of magnitude as a carburetted engine.

With regard to the EcuTek map tweak, watch this space, I have a request in the ToDo list @ EcuTek which will be "interesting" to say the least

Some cars just like to pop and bang, some don't, but generally stainless steel exhaust system do seem to produce lovely pops

Cheers,

Pat.

 

99 octane fuel, hot exhaust (SS bb and dp) and ecotek and you are like small WRC

 

Motorsports ECU running Anti-lag strategy, No dump valve, Decent ALS airfeed arangement, hot free flowing exhaust... somewhat more like a real WRC car.

 

Anti-lag ahhh my next motor will have that! It's the REAL way to do it. :-)

Overfuelling is ok in small doses. My WRX Version 6 used to love being bounced of the rev limiter, it spat out flames and popped wonderfully! That was with SS BB and DP.
