Hi all, can standard S2 rs turbo's chatter cause I thought they couldn't?? I currently have a DV fitted but thinking about taking it off!

 

NO not really! the way they are. If u run lots of boost it will only be quite. Get cossie managment on there and hey presto

 

tHINK YOU NEED TO DO AWAY WITH THE AIR SENSOR THINGY THE FILTER GOES ON AINT IT??

 

Yeah mate the air fuel meter but onlt way to do that is by changing managment

 

I got a little bit of chatter on mine. take it to Karl Norris for a stage 1 tune, get rid of the dump valve and chatter comes free

 

it does, but its v.quiet..

theres a lot more to it techy-wise but thats all you relaly need to know...

if it chatters loud then its either not using KE-JETRONIC or you have a leak between the metering head + turbo (NOT good!)

 

Don't know much about management so can you fit cossie management without changing to EFI?

And how much for that stage 1 tune up??

 

Jim, I'm not taking a leak on my engine for you again you sick fook.

Check out Karls site for prices and info:

Had a quick look at the site but can't see any prices?

 

Mine runs k-jet,boosts at 18 psi and chatters.

 

You're better off ringing him or sending him an email.

The stage 1 includes: uprated actuator, 3 way bleed valve, custom chip/remap

He checks the car over thoroughly [trust me on this one ] and he maps the car live, sets up all the fueling and makes a good cup of tea too

It was Ł350 which I think is cheap as it tranformed my car from a grotty old RS to a 160bhp cossie killer. lol well it's quick anyway and the torque figure was awesome.

I know there's loads of other tuners out there, Stu [motorsport developments]does a similar set-up, power engineering could probably do it too, depends how far you want to travel. I travelled a few miles to karls and wasn't disappointed.

It's definitely worth getting one of them to check it over and set it up though

 

Mine chatters at any boost and it's doing my head in. Any recommendations on how to make it totally quiet are welcome...

 

The RS Turbo (as with ANY turbo car) Chatters as you close the throttle. However, because the return path of the air goes through the Metering head, it loses its volume. You will hear it on most RST's to a greater or lesser degree and more so as you increase the boost. You will also hear it more with an Induction kit (however, the Standard Airbox is the best option!!)

To fit alternative management just to be able to hear chatter is ridiculous IMO, but we would happily sell you an Omex system if you want!!

Fit a Dump Valve!!

 

mines on KE and 7psi and it chatters

 

put your fingers in your ears when you come off throttle.

 

I have a better idea. Take the turbo off and remove the blades with a set of Snips. Then it won't chatter.

 

I never thought of that.

I bet Jim did.

 

Mines on KE-Jetronic and at 25psi it chatters a bit.

Throw your DV in the nearest skip mate it may not chatter but the car will run a lot better

 

Buy a Mk5 RS2000, I hear they chatter pritty quietly

 

Throw it on ebay.

Someone with a saxo will buy it and claim it makes their car faster.

 

 

so any turbo'd Ford running on standard boost won't chatter?

as for my standard cosworth engine it won't chatter without upraising the boost?

 

fiesta turbo's chatter pretty well from my experience!

pretty sure cosworths will chatter at standard boost - its just those escort turbo's with crappy MFi!!

 

cossieman, mines is std on std boost and it does...it's just luck i think? lol

 

don't standard cossies have a blanked off dump valve?

 

think so, but i'm not sure

 

I thought I read somewhere that they did mate, could be a reason behind no chatter.

 

std cossies got a recirc dump valve, take it off and blank airbox-turbo hose and blank off ic

 

never realy given it a try

 

cheeRS mate, but what does ic means??

 

my Series one used to chatter really loud just didn't last very long.
Standard Cossies will chatter with an induction kit my mates 3 door sounds
quite good it is only running 7 psi

 

ic means intercooler dude!

 

Ic means Inter Cooler

 

okay guys, now i got it

so i'm gonna give it a try tonight

took a while before i've knew what IC means but that's what you have with





























































those fookin stupid foreign goons

 

 

stop insulting him - scotland is only just foreign!!

 

oiiiiiiiiii

 

well, i got pretty well away with it

 

and what to do with the hose that goes from recirc dump valve to plenum chamber? i suppose i have too blank it off too??

 

yep, i have to blank it off too

just read another post about dumpvalves on saphh's.
