can you run anti lag with a dump valve fitted thanks

 

Yep, but needs to be dual piston type....

 

talking of dump valves, i have a bailey, and a mate has a bailey, they look the same from the outside ,but mine has a rod through the middle that you can see from underneath, but his doesnt . whats the difference?

 

You can, but seems to work a bit better without.

 

would it not be pointless though, because when you are off throttle e.g braking for a corner and the anti lag is keeping the boost up for when you re-apply the throttle, the dump valve would be getting rid of the boost created from the anti lag running

just a quick thought, probably completely wrong but would like to know

cheers

you dont run anti lag ALL the time do you?

What about proteting the turbo when your not running it

 

my thought on the subject is that a dump valve has a spring in it that keeps it closed. the spring force has to be overcome by a difference in pressure for the dump valve to open. that normally happens when you still have boost pressure one side of a closed throttle, and vacuum the other side of it.

with ALS activated, you don't have that pressure difference due to the bigger bypass valve, so the dump valve will probably stay shut (depending on the spring force).

am i right?

 

You have a dual piston one.

Nick,
Yep, that's my understanding. Dual piston ones seem to have a better set up for keeping the piston closed.

 

is that good

 

Do you still run ALS mike? Didn't hear it at national day or was I just not listening hard enough?

 

I had to turn it off as the exhaust kept melting the anti-roll bar bushes as it was .

 

..i ran anti lag with a single piston bailey dumper

 

has anyone made a marram shaft for a GT35 yet? , recon mild anti-lag would still kill it?

 

...i was told by Universal turbos NOT to run any anti lag with the GT series.
