Is it normal for an rs to pop quietly when going down the rev range in gear? Would this mean its slightly overfueling?

Also how much quicker would it be quarter mile stripping rear seat out?

cheers

 

hope this isnt true for you but wen my mates started to do that it eventualy turned out to be a melted piston

hope this isnt the case for yours

has it bin set up recently?

 

late last year

any other signs of melted piston?? Any easy way of checking?

 

is there any noticable smoke (blue/black) on idle or over run?


maybe just needs setting up again m8-like you say could just be down to fueling

 

Loads of em do it mate, shouldn't worry about it too much! Like u said, tis just overfuelin on overrun a little bit, shouldn't be as bad when the fuellin's bang on, but mfi's not exactly accurate is it!!

 

They shouldn't actually do it on over run KE Jetronic shuts off fuel supply on over-run as part of its **fuel economy** but a lot of them do do this. Wouldn't of thought it was anything to worry about

 

mine pops alot when coming down the gears. does need setting up though, running a bit 'odd'

 

glad to hear others do it also! Doesn't smoke, starts up first time and runs sweet just never noticed every now and then little popping! time for another tune and boost increase i think

 

i'd do the same as you, but i have a police siren in my engine bay when it comes on boost

 

Check your throttle switch clicks if not adjust it till it does.

 

what a load of bollocks its all down to what back box u got on ur car

 

i thought the big bore exhausts make these noise

dont get it with a standard RS exhaust i think

 

Every single rs that i've owned does it!!!!! and i've had a few

 

mine does it too! u would only gain around 0.2of a sec if that, i was doing runs with a stripped out motor then wen i was packed up for the weekend with all me camping gear and bbq thought it would be funny to see wat it ran and it did pretty much the same, big differences i found wer taking headlight out to let air into filter and letting frnt tyre pressures down to about 17psi

 

Melted Piston???

And the engine kept running?

 

mine doesn't - proper silencer. Drops the odd flame though

 

My old RST used to make poping noises when fitted with a Scorpion.


Changed it for a goose and and it started to quack

 

 

Mine pops and bangs LODAS although I know the fueling needs turning down slightly.

I wouldn't worry about it...but get it set-up when you get chance!

 

it was mine that melted the piston and kept runing (kind of) just smoked alot!!!!!!!!!

 

I remember one time I gave mine shit off the line wheels span a bit and it popped like a muther fooker sounded good

 

It couldn't have been that melted then

 

Tony, u'd be suprised. Seen them run with a hole in - lots of smoke but still run.

 

Obviously not putting enough effort in then. Unless your piston looks like this, you aren't doing it right

 

since i changed my exhaust from a magnex to a 4" mongoose it does pop a lot when going down the gears. it has been also recently set up to.

 

Thats pretty fucked Competition time then lads see who can fuck their piston up the most

My mate works for Renault and he's slowly but surely building up a collection of "Mass Destruction" on top of his tool box, i'll see if i can get a shot he's got a pretty fucked piston in it. Got a turbo i'm donating to him aswell i'll get some pics of that

 

it wasnt as bad as that but hey a melted piston is a melted piston!

Will post some pic of mine soon
