I find that getting a life normally helps with these situations. Whenever I get the urge to want fake pops and bangs I think to myself
"No that would make you look like a cunt"
Normally works.

Uhhhhh, if it's wired directly to the coil pack as it should, then you're getting a misfire.

Sooooooo you're just not hearing it it's down to your exhaust.

If you got a cat, you're gonna hear nothing unless you turn up the fuel and ruin the engine.

you guys are so boring. the pops and bangs of a spark cut are fun!
Normally a decat helps result.
As does a warm exhaust. :)

I'll go do some work on an engine I have in the garage tomorrow, I'll show you a rev limiter on a proper engine ;) (here's hoping the limiter still works!)


You should just install a 16V engine, they naturally pop on overrun, especially at about 1700rpm and changing gear at high revs.

you have to tap the throttle, let it bounce of the limiter for a couple of secs then keep tapping it

I have an RX7 that barks 3foot flames out the back every time i let it off boost, i can say honestly that the fuel efficient fun vtr popping away is good fun!! Its just a spark cut, not a flamer kit ;)

pahaha, pal, dont even spoil my night. . . . probably. :')


They do oil by design though, the reason they bang their tits off is their map.
Because they fire on every rotation, and run up to near 9K they run rich as hell to stop them melting the cat. Mazda even put an 'air pump' in simply to pump air into the exhaust lol On a standard map they cut the spark at 9k and let an impressive fart out the back.

If you just want a pop - get a packet of crisps - eat them - inflate - then burst

This should satify your pop requirement!

If you got one with launch control set that to around 3k revs then rev upto about 5k, come off gas and press button.
That should make it bangs.... Mine does.

My 106 GTI has an air pump.

I have racecar now?

In fact, here's a standard 16V. I'm tapping the throttle.

Hard cut or Soft cut? I found in 4th around the launch control limit if holding the button while driving it does bang, just not sitting still, that may of been on soft cut also i cant remember ill have to check

See mine doesnt bang like that on launch control, i guess they're all different!

It's all in the set up, mines soft cut at 2500 hard at 3500 retard to 1degree and cut fuel and spark 9 events from 15 gives a very clean 3500 rpm launch..

Why would launch control make pops and bangs? Are you thinking of anti lag? :S

noob or trollin?

It cuts the spark so the revs stay at eg 3k whilst your right foot is buried.

Cut spark + full throttle + hot exhaust = boom.

Viper
3rd March 2013, 09:05
Apparently noob. I thought it just held the revs at a certain point, didn't know it did it by effectively cutting out.

Either way I would rather have anti lag.

not entirely true

Yes they are.

Not always, and the exhaust doesn't have to be hot. the excess fuel (now sitting in the exhaust due to the spark cut) which provides the pops is primarily ignited by flames coming past the valves.

Proper rev limiters cut the fuel or retard the timing. cutting the fuel is hard cut and retarding is soft cut.

I made a soft cut for my 1.5D once, hilarious. :P

Yes, you are noob. anti lag is for turbo charged cars :D not spaxos.

If you have an electronic TB, you could set it up to hold revs lower through the ECU. but I don't think it would be as effective.

Why would I go to McDonalds to rev my car?

If I did want to be part, why would I take a lowered car which is OEM.

noob :homme:


Clearly, you don't rate my car as being able to pop, you must be part of their crue, only official McDonalds car park members can give ratings out.
