Does amyone know if the plastic restrictors in the amal valve should be removed?

Does it make any difference?

 

i got a spare one if you need it. someone said when i had the stg3 stuff on mine i should have opened the holes out but i didnt bother.. its off a 2wd tho so not sure if the same..

 

Rejetting the amal valve will alter your boost curve. It works like an electric bleed valve.

 

Depends on you mapper, and what they prefer to do jet wise!

 

i tried it with them out, and it holds a lower boost level , i know i can adjust it up again, but it seems to come on boost slower than before, i just wondered if it was a done thing or if i shouldnt do it? cant really see any gains from it tbh?

 

As said it purely depends how you want it set up, when karl set mine up with a 28psi spike on greens I have no restrictors in the amal valve IIRC

 

This may help, Mike Rainbird just posted it up in GD:


First set the wastegate preload to 9 psi by temporarily connecting the compressor outlet to the actuator using a short piece of tube.

This should be about half a hole of preload if using a -31 (as in when you place the actuator rod over the wastegate shaft, you can see half a hole showing).

Then reconnect all the amal valve piping back to normal.

The restrictor in the amal union that normally goes to the airbox needs enlarging slightly. Change this to around around a 1.5mm increase using a suitable sized drill bit (it might be worth going up in 0.5mm steps, as you can always make it bigger, but you can't make it smaller!).

With this done the boost should be holding about 15-20psi.

If want more than the above results you will need to enlarge the restrictor in the other amal union, but like the above, go up in 0.5mm increments for the same reason.

Once you get NEAR what you want, THEN use the actuator to fine tine the boost limit. But DON'T slacken it to reduce boost (in case the restrictor was opened out too much) otherwise the wastegate will rattle. Also don't wind it in more than a holes worth - open the restrictor a bit more instead to get the required bleed off.

Hope this helps?

 

cheers mate, i think i will put em back in!

 

dont give JTECHSAFF any advice, if it goes wrong he'll be persuing you for compensation

JTECHSAFF when anything goes wrong.

 

LOL @ jeremy scott who is affraid to post his own name incase his boss finds out what hes said.

 

If copying and pasting is a crime, i put my hands up, guilty as charged. but to be honest, if you didnt want these things to be seen........... just maybe you shouldnt have said them?

 

LOL @ james wills, who hasnt a clue who he is referring too

oil oil everywhere but not a drop in the sump

 

actually its fixed and 5000 miles in. plenty of oil in the sump no thanks to Cosworth.


Well done three posts and cracks at me....... shame you cant be of more use really.

Just to say, if i do get a pay out which i doubt i will, but if i do all the money is going to charity........... i dont want it or need it
