Can Overrun map cause Damage!

[Tony Hunter]

nah, the pops are occuring in the exhaust, not in the cylinder. The only things that will be damaged are lambda sensors and silencer baffles

I was joking, Danny my dear.

 

[EVOgone]

Valvers are even worse.!!!!

 

[John Gordon]

I can't afford to pour fuel down my exhaust just for s***s and giggles. Plus I don't think I could drive through town with my car making that kinda racket. Its bad enough with the exhaust it has on it at the moment, I cringe as people turn round and stare.

I know it's a different car, but ALL 106 GTI's will pop and bang on the overrun with a decat, it's the way they are mapped from the factory

It's fantastic fun and always puts a grin on my face

Never heard of a 106 blowing up because of it? So I'm sure if you had it properly mapped and didn't go stupid it shouldn't be a problem

I heard what sounded like a Rice Kirspie factory being hit by a tsunami on a stretch of dual carriageway in summer. I turned around to see a 106GTI piloted by Devo The Chav.

That noise simply can't have been normal, it was obscene!

Put it on my car last night, it's mental! It didn't do it straight away and I was disappointed. One last rev and a massive gunshot like bang happened, s**t myself.

Flames are cool aswell, wasn't expecting them tbh!

My exhaust back box exploded, had baffles all over the back of my car looked like i had ran over an old lady! then it all collapsed and something was blocking the pipe! so went and got a Yozza. Granted it was a toyosport one that exploded so wasn't surprising really

Although the popping noise occurs in the exhaust, the high EGT very inefficient burn actually starts while the gasses are still in the engine, which leads to elovated exhaust valve temperatures, so you risk damage to those as well, and degradation of the seal between the valve and the seat as well.

Its fairly mild due to the small volume of gasses actually involved (as its doing this on a nearly shut TB), so not a massive issue, but people should be aware that unlike what they might think from what you had said there, the burn DOES start while the gasses are very much still in the engine, the popping is just the burn finishing late, it isnt when the burn starts.

Mine has actually stopped popping for some reason, 4months or so after I put the map on.

Pops the odd time, but probably 25% of what it used to.

Haha you can't base one Chav-chariot on all cars. I had a 106 Rallye with a 2" pugsport and it really did sound fantastic. A very nice raspy sound rather than something you could fit your leg in and sounds like the space shuttle taking off!

They do pop and bang for fun on demand though

It's not how you stand by your car.

All these comment but does anyone know of anyone who has seriously damaged their engine?....

How many pictures do you want?

seriously? im about to do this... im having second thoughts

 

[bloke]

don't bother.

Yup, dropped valves usually.

 

[.J.a.m.e.s.]

don't bother.

may i ask why?...

 

[Ex-User (72296)]

I want to see pictures just out of interest!

me too

Read the rest of the words - honestly it's covered entirely on this thread - look at Chip's post for example.

 

[.J.a.m.e.s.]

I'm about to reprogram tonight.
Is it worth putting my car battery charger on it whilst doing it?

 

[Budgie]

Monumental levels of mong.

Monumental levels of mong.

What do you mean...

 

[jinjur]

Yeah, apart from the damage this is doing somewhere along the line from engine to bumper.....I think its a bit.....well......"Mong" was a good term. lol.
I don't see this as being any different to those flamer kits that full-on retards fit.
It has no purpose.

You might as well put a flashing light on the end of the exhaust and bring a cap gun out with you.

Don't get me wrong.....when they happen naturally, that is a different matter. Mine has the RSTuner performance map on it and will pop once in a blue moon, particularly if I am cooling down after a ragging and that......is perfect

My old engine.

Silly old valve, where did you go?

 

[dann2707]

Probably landed in the Mcdonalds carpark or multistorey car park
