The thread on my actuator was knackered and it may not have been functioning to well so I bought one of these.

 

If build quality is anything to go by it will be good. Its a solid bit of machinery, twice the weight of the flimsy Courtenay uprated one. Also you can change the spring in it to alter the 'static break off point' whatever that does

 

Fitted but not really tested yet. Will feed back later.

Just been for a 'spirited drive' around MK's dual carriageways and roundabouts and its a vast improvement. Not N/A delivery or even the smoothest turbo delivery but loads better that it was. builds up nicely, holds reasonably well on part throttle and releases boost smoothy.

 

Maybe my last one was fooked but its certainly better than I ever remember it being in the last 7 years,

That's good to hear Paul, I'll be giving it a go as well I know you've had the same issues as me about the switch type power delivery so can you now regulate part boost more accurately and is the on/off transition a lot smoother? Also, did you have to pre load the actuator the way Courtenays did with the others or is it totally reliant on the spring weight? Sorry about all the question but need to find an acceptable solution.

It's called a super charger

Oooh, look who just piped up Just couldn't deal with all the whinnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnning, beside I prefer a challenge not just stamp and wait

Yes I believe so. Will take a  little more time to evaluate properly but first impressions are good Also, did you have to pre load the actuator the way Courtenays did with the others or is it totally reliant on the spring weight? Sets up exactly as the standard one does. Setting was a lot easier as the nuts/rod were obviously new but they are stainless steel so hopefully should not rust or get affected by the heat as much.

 

10PSI spring seems to work the same as previous actuator. Overboosting to 25 and settling around 16-21. The 25 is a little higher than before...maybe I should wind it off a turn or two?

 

Not sure what effect having a different spring would have. Do ask Courtenay and let me know.

I think it's called an aftermarket ECU and decent remap!

[siztenboots]

but this one is also courtenay branded, ie. price inflated

In the long run, absolutely.

To be fair it's cheaper from Courtenays than on their own website.

Back in the day we always used to fit a -31 type actuator when upping the boost.

 

Granted it was on Cossies/Integrale's tho
