Fitted the .48/60 T3... Interesting results! LEAKS FOUND!

Thats normal when on boost Rob, does yours do it off boost? You can also adjust the MAP sensor lag factor to try and eliminate it too.

It happened at a very specific rpm points, i believe it was some sort of resonance in the map vac pipe, as a shorter/longer pipe changed the problem rpm. Not a huge problem any more but it took some head scratching at the time. Map sensor noise shows on nearly all other logs to its not obviously the map straight away.

Looks like it could well be my actuator...
With a whole hole of pre-load it only holds 11psi (MAP) which is far too low, i'm sure it should be somewhere nearer 20psi with that much pre-load, but I can now get it to hold just about 20psi using the Apexi so it's looking like a -34 is on the shopping list!

Sounds like you found your issue Karlos. I've come across this issue before hence why I asked about pre-load right at the beginning.

Definitely not right. When I used a -31, I tensioned the spring so that the waste gate lifted at 11 psi then the amal valve bled the air off to up it to 15 psi. Even then it wasn't a full hole.

apart from that when it comes on boost i do not get time to look at the gauge to see what the pressure is actually doing ,i am using a zeitronics gauge & it was not in the best position but i will get a new 80mm boost gauge when i finish this rebuild .

Well done Karlos... Sounds like that could be the issue! I bet it proper rewarding being able to map it to your new turbo. Would sort of gains do you think you might see BHP wise?
On a side note, as mines on standard OFAC (stage1 superchip) and it has no way of knowing theres a 40/55 t3 on it or any t3 as ofac's designed for a t2 turbo. Would it be leaning off as you say yours now needs more fuel?

I found when setting up electronic boost controllers, if you want to ultimately be running 2 bar odd, it's a good idea to set the actuator to hold 12-14psi with the controller off (actuator pressure) , then you don't need to use much over 70% duty on the controller which is when they work most efficently in holding higher boost levels

It's very rewarding yeah for sure, BHP wise... hmmm I'd love to smash the 300bhp barrier but that is far from easy! Jimbo has done it on a .48/55 so my 60 trim can flow enough it's just whether my new manifold, headwork and cam are suitable and of course if my mapping skills are up to it!
lolRegards your learning off, if the chip was not written for a stage 3 T3 then yes your are correct.

Would that not mean it would open late if pressure is leaking through the diaphram?

It's an XR3i one (like what Christian ran) with a cossie TB but will have an enlarged plenum as stock it is quite small IMO.
Here's the only pic I have so far, should be finished by the weekend!
After looking at an EFI manifold and then this one the difference is night and day flow wise, even down to little things like the end of the runners on the EFI manifold being smaller and with a bulge interupting flow where the injectors fit, should see a big difference I think!

I don't know mate, maybe on bigger turbos. But my cam is a lot bigger than yours and I just saw 303 with some brave ignition timing
My mate has his engine on the dyno shortly with Newman phase 4, same spec head as mine tubular manifold and crazy cage inlet, 60/.48 I'll let you know how we get on with that, hoping for 300bhp

Yeah you will need a chip written to run with a stage 3 T3 or it will be lean for sure.
Dont think I'll be quite 300bhp but high 200's easily, I have gear based boost control so 1st and 2nd will be throttled right back to aid traction

Ah, a neat trick...! Im sure that pays dividends in the "traffic light gp's"! 250bhp in an Escort will be rapid, anything more will be a nice bonus for you i guess!
Well thats sorta the final nail then really, MS it is next then! Of course then about 6months of learning to map it correctly - there will prob be plenty of PM's your way m8 asking for all sorts of assistance some about MS aswell lol!

Fitted a brand new Garrett -34 Actuator today, half a hole of preload and still doing it! Still wont hold any more boost really than before.
Here's a vid of what I'm talking about, it isnt the clearest as the car is quite bumpy and typically it didnt do it quite as bad as some other times but you get the idea....

We were in 4th gear from about 1500rpm to the limter then into 5th.

Hello Karlos,
I suggest that you remove your boost controller from the equation.
Plumb the -34 wastegate actuator to the turbo. Simplify the boost control.
Now see what happens.
Take a video.
Cheers
Perry

Karlos, yes you're right. I don't know why I said there might be a pin prick in the diaphragm.
You have unstable boost so i suggest you ditch the boost controller and try it purely on the actuator.
This is a good video of actual surge. The boost gauge would be going spastic and having an epileptic fit while it's occurring.

lolWith it off peeks about 14psi and holds about 12psi, duty is about 62% Rick.

It can't hurt Karlos, its just another potential problem to eliminate, once you have eliminated it you can look else where, but suppose the boost controller (or solenoid) does have an unexpected fault which is causing your unstable boost, and you don't test it you'll just be chasing your tail around for ages
Can't hurt to unplug it, wind up the actuator and try can it
