Turbo Mini Forums

not really looking for anything serious ..just one than can cope with anything from 8 psi and upwards to replace the old standard item on my car at the minute.

thanks

cheers man

these actuators much good ??

Can anyone tell me what the notation -31 means, please ? I bought a Collins -31 RS Turbo actuator which gave me nearly 20lbs boost until I changed the spring,as it was an alloy one which could be dismantled.

-31 ia just the end of the garret part no (actually -0031 iirc)

the -31 starts opening at about 7-8 psi

Thanks for that, just spotted a similar answer on another thread. I must have been sold something else because, as I said, I got a mental 18=20psi on mine at first and unfortunately its not the first occasion that I have subjected the engine to this sort of boost.Does make the pistons creak a bit !.

Generally speaking, I was told that the last part of the Garrett actuator part number is a dash and a number, which if you divide by two gives you the operating poundage of the actuator.

A -18 is a 9 psi, a -24 is a 12 psi and a -31 is a 15-16 psi.

The Cossie T3 9 psi actuator part number is 430099-18 if this helps

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Schrödinger's cat - so which one am I ???

Ive a couple of 15psi actuators here, last used on my RV8 TT some years ago.

They were only a year or two old then, so old, but almost new lol

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

I may have a billet avonbar one up for grabs in a few weeks

If something is worth doing, it's worth doing half of.

thats great thanks for ll the info guys..ill have a scout on ebay and see if there are any actuators suitable for a approx 8psi...stevie are your actuators the type i could change the spring on..ill only be running a max 10psi on mine so wouldnt need anything to high....and john def let me know if you end up having that avonbar item up for grabs, as if i dont have one by then ill have that off you

2nd dibs please John :)
