What to say to this?

[GSXRk2]

This guy has been driving a few months and is a typical seafront fiesta driver with duck-taped on back box etc.. he's selling the car.. not quite sure how to reply to this..

"Sam Jolliff: Thanks Forr The Dickhead Comment. Il have you no i havnt had her very long and shes a full service history. your aloud to floor it once in a while its good for the engine

me: how in any way is it good for the engine?

Sam Jolliff: because people who drive like grannys clog the engine up.. when you drive it hard it clears all the valves and release burns allot of the shitty deposits "

i must ad he doesnt floor it once in a while. i've never seen someone drive like such a twat....ever.

[GSXRk2]

..........is this true?

You have started a thread about a conversation between you and some ned and what - are you really asking someone else to finish it for you? I'm slightly confused Do you want to buy the car or have you just been spamming up his ad thread somewhere?

He does have a bit of a point though. My mother always seems to bugger her cars before their time by never exceeding 3500 rpm and always being in too high a gear. That said obviously the reverse will be be equally if not more detrimental to the health of an engine.

Seeing as that is what you are accusing him of maybe you should point that out to him?

Your first post in a bike forum is this?

Engines should be used just not abused.

anyway ..i cant think of anything cnutish enough to say back.. mainly because i dont really know fck all about cars. (as delvey91 will know)!.. Is he right or not? I'm assuming it's only in extreme cases where opening it up with 'clear the valves' etc not on a crappy little fiesta/zetec or whatever the funk it is and he's just giving an excuse to drive like a nob.?..

Anyway.. if he's so concerened about keeping his engine good.. he would have had the engine balanced/fuelling set up correctly etc for the engine to run properly with the lump of metal he's got bolted on the end of his zorst?..or this only mainly with bikes?....

[tutton]

Dosnt matter what it is, opening it up once in a while does it good, good example of this is 2strokes, yeah fine your not supposed to rag them, but if you dont open them up once in a while you get all sorts of problems with powervalves sticking and gumming up etc.

For a backbox or just downpipe to backbox exhaust it wont need rejetting on a car.

So hows devonbikeriders then?

Know as a "Ferrari Tuneup"......

Supposedly the mechanics would do your normal service then go thrash it for a bit to get it nice and hot.......

On asking various mechanics they seem to differ a bit normally....

When the mechanic in question is a quick driver with his evo, it apparently does the engine a world of good....

Also he said something about an engine which is always low revs can build up a wear ridge on the bore at a lower height that one that is ragged. If one was to the rag the low revved engine the rings would collide with the lower wear ridge and possibly chip/crack. Or so the theory goes.....

[metalangel]

I'm told that the TDI engines used in VAG cars need a good ragging to stop the turbo vanes sooting up. The chap in question on the TDI forum goes so far as to say that once you're warmed up you should be shifting at 3,000rpm (redline is 5,000).

For a Transit van, maybe, but a 110bhp car it seems a bit much. Tis fun, though.

No but there is slight more stretch in the conrods and bearings etc at high rpm than low rpm. We're talking fractions of a mm.

It follows that the piston rings only go a certain way up the barrel if an engine has only low revs. When the revs are higher all of a sudden, that slight stretch in the conrod etc means the rings move a fraction of a mm that they're not used to and collide with the wear ridge, this chipping them.

Its also why engine have a squish clearance (apart from gas flow and cooling), theres a enough room between the head and piston at low revs so they don't collide at high revs.

A "perfect" engine wouldn't have a squish (if cooling was ignored) as it is effectively a "waste" of compression. The gas in the squish band, that normally doesnt burn (although the unburnt gas does aid cooling), could be put to better use if it was all crammed into the combustion chamber.
