Forge Dump Valve on JCW

[Mini William]

I asked for an answer to my question in post 1 not to people opinions of BOV's if i wanted opinions (which i dont) i would have asked for opinions.So does anyone have one???

[wagger]

hi matey,iv fitted a forge bov and alta induction kit to my r56 jcw,sounds really good, if your not in the mood one day drive light footed and u will not here much sound,so u have best of both worlds.so i say do it and make some noies its your toy. let people have there say , thats good but ,,,,,, chavy,de-value,and age dont make me chuckle...... off to wills for a remap sat ,,,,,,,,,,,,, ho my goodness , a might get sent to the headmasters office ....................... hehehe

Whatch out sonny you sound like a Chav

Turbo cars are the way forward stick your supercharger up your @&$£ .......... watch out for the incoming

Bring the M3 round any time William for a cleaning.
Just so long as I can rev it up in the driveway and let the neighbours hear the V8. (not too loud though mind as I dont want my neighbours thinking that I am friends with a chav)

What BHP are expecting from the remap? (will as p-torque, hes a good guy)

How do you find the alta induction kit?

I no that Rams ( Mini Trainer) has a forge BOV on his R56 JCW with no problems and it sounds good not too loud and is made for its purpose.

Chav options like this are what end up de-valuing cars like mine and your JCW. I doubt they will have any benefit to a modern turbo engine which means they're purely for the noise-factor.

If you want to impress people, take them out in it.

Before you call people chav's for wanting to do this then i think you should read up on the purpose of a BOV its not just a noise maker, i agree some are desingned for extra noise but it still has a purpose.

If you want performance, it would need to be a remap, intercooler, muffler delete pipe. The JCW eaxust system is as free flowing as any aftermarket system so that will save a few pennys, however removing all the cats will get you an extra 10-12BHP (not for road use).

My advice would be to fit an Alta induction kit, it will give you more induction noise and you wont have to buy some rockports.

PS, I'm not impressed by your M3 comment, sorry .

(maybe there not all driving Audi's after all Mr Clarkson)

Again its not purely for the noise at all.

Funny how a valve is chavvy but a filter isn't.

Each to their own, it's your car, do what you like to it...

I have an R53 MCS and its tuned just like any other car out there that you call a chav's car.

Explain the difference from you lot modding a car and a saxo owner????

So when they predict that the tuning market in the UK is worth billions each year do they have a seperate prediction for the special upmarket MINI tuning?

I dnt think so, everyone who messes, mod's a car all come under then same roof regardless of the make of the car so i think people on this forum need to see the light if you mod it. It may be more tasteful mods and not as "chavvy" but its still the same.

Purpose
Blowoff valves are used to prevent compressor surge. Compressor surge is a phenomenon that occurs when lifting off the throttle of a turbocharged car (with a non-existent or faulty bypass valve). When the throttle plate on a turbocharged engine running boost closes, high pressure in the intake system has nowhere to go. It is forced to travel back to the turbocharger in the form of a pressure wave. This results in the wheel rapidly decreasing speed and stalling. The driver will notice a fluttering air sound.

This helps prevent the spines on turbos failing therefor it has a purpose.

Ill put that tasteful same old quote at the end of my post.......................

Each to there own i guess.

Also are we tarking about a Factory JCW or a Cooper S JCW as Rams is a stage 1 kit. Just thinking it might be ok for 1 but not the other.

Fair point, Rams is a Stage 1 not sure which the thread starter means.

Just my point of view,

Anyone who fits one of these divertor is a bit dim in my view.

Firstly its not a dump valve its a divertor plate. What it does it allows a certain amount of the boost to be vented to atmosphere to give the noise ( which is rather lame from the ones i have heard)

A dump valve in its orginal form was only really needed on earlier turbo'd cars such as early fords and Renault 5's etc etc. Reason being as they did not vent on off any of the boost pressure. Most turbo cars after 1990 with proper ECU's came with recirc valves built in and from then on the dump valve as its known ( vent to atmosphere) was no more than an aesthetic addition as the car already had the required recirc valve built in. Standard cars instead of venting the boost pressure recycle it back into the intake giving less lag etc etc.

Now in the last 8 yrs or so certain cars with advanced ECU's have come along that don;t like this excess boost then venting off to the atmosphere as the ECu expects it to go back into the system. So if this does'nt happent he ECu over compensates and chucks more fuel in which ends up making it overfuel. This then has really small differences elsewhere in the system and can then affect perfromance or even trigger limp home mode. Now these differences may be only small, but those who have any experience of the old VAG 1.8T will know what problems this used to cause when people fitted dump vales or similar divertor plates like the forge one.

My advice is steer clear, the R56 S engine runs very tightly and to start removing boost to the atmosphere is no different o having a hole in one of your boost pipes. there is no benefit to fitting it and they really do sound crap, at least a traditional dump valve sounds purposeful.

Guys this is just my opinion so make your own minds up, but whats the point.

Ant i did actually no that but i was getting fed up of the chav talk around this place.

My brother had a Focus RS for 3 years, it had a dump valve on there from new he removed it 2 month before he wrote the thing off and the car drove a milion miles better for the reasons above.

Its a fact, like it not most people will think Chav when you mention a BOV/DV, this post has proved it.

Take rock ports, probably a very good boot to have this time of year, but you cant help but think chav. Could just be my generation (I'm 28).

As I said at the start each to there own.

[badwolf340]

well if nothing else ,we are on page two

[badwolf340]

are there any specific futher upgrades/remap's for factory r56's.tuning wise who to use.
