John V is the man you want to speak to on there, sort of a guru.

I agree its ****ing boring sometimes. Everything seems to get questioned and criticised by 20 people who are think they are race engineers. I rarely ask questions on tb as a lot of the info is there but you have to search for it. Also every time you ask questions about chassis components you get pointed to kaplhenke, rather than having a worthwhile discussion. While bens products are very good quality it is not the be all and end all.

Best thing to do is lurk and ask questions if you really have to then prepare for the worst. John V however knows a lot he can be cryptic sometimes but he's is not one to spoon feed he likes to make people think.

+1 for John Vanlandingham. Great bloke... Cossie Garretts spring to mind when I talk to him.

So, today i have fitted the Atmospheric DV and the blanking plate and as was said it stalls on idle, when will i listen lol. so the new plan.

I am NOT removing them i am going to find a solution to this very stupid problem lol.

now i have tried the butterfly stopper adjustment screw and unfortunately its siezed solid so now i think i need to find a fresh TB thats not seized so i can adjust the idle closed position of the Butterfly. What i di manage to do was bend the stopper for the spindle abit and that has helped alot, instead of it stalling instantly it now idles for about 2 seconds then stalls, that should in theory be enough for me to catch a stall when out and about.

1 thought that ran through my head, good it be partly down to a dying Idle Control valve??? ie not working properly or partly blocked??? or maybe just needing a good clean???

PS, the DV sounds great but I am getting Turbo flutter and i have read different views on weather this is good. i have watched the DV and its opening and closing as it should and its opening instantly when the Butterfly closers but I am getting alot of flutter back through the Air filter.

It is not seized.
It has a locknut.
This is correct design.

Nope, no signs of a lock nut anywhere. i will grab a pic tomorrow.

Kudos for ricing up the car and choking it...


Locknut is in the back. But the screw is known to sieze.

The first time I adjusted my idle screw I thought "oh its not moving",
thought a bit more, had a look,
slackened off the locknut ... bingo.
Adjusted the screw, tightened the nut.
Job done.

Cheers guys, its raining at the mo but just been out in it and its idling at 4-500rpm ish so only needs a small tweek lol

Well my persistance has paid off. After hours of research i have learned that turbo flutter isnt a bad thing, compressor surge is very bad. Turbo flutter when you let off the throttle and it flutters for a second before thw Blow off valve opens is ok, so with that in mind i have solved the wont idle issue.

I have now got the idle running off the control valve and its idling perfectly with no stalling.

What happens is when its on idle there is still a small amount of pressure coming from the turbo, i know this because if the DV is set too soft on idle it stays open and there is pressure coming out of it, the DV being open on idle is bad and this is what is causing the stalling. Now because i was smart and bought an adjustable DV i have hardened it up so on idle it now stays closed (how its meant to work) this now means that small amount of boost pressure (not even 1psi) is now being fed into the idle control valve and is now allowing it to work as it should which means all my idling issues are solved.

But, this has come at a small cost. I now have a small flutter before the DV opens meaning it sounda like an old Group B rally car constantly. Girlfriend says it sounds great and personally i think it does a little too lol. But if you are a person that waants subtulty then this set up is not for you lol. Its, how we say, very chav!
