Why do people use bleed valves instead of buying the right actuator, or is there another reason.

Do you feed them into the car.

what benifits do you get

Thanks in advance

 

Isnt a standard cossie amal valve basically a bleed valve?

 

there are benefits, when used correctly!

 

Anyone

 

You can use a bleed to give you a midrange boost spike - very useful indeed

They only have a bad rep because people are tempted to mess around with them

go read the msd website thers a write up on bleed valves there!

Gotta say mine was put on to make it easier for the tuner to adjust boost cus im such a fussy wanker! and i gotta say i aint tempted to play with it at all....mainly cus i cant adjust the fueling !

 

Would you care to expand

 

On my cossie i got one but it was on there when i got it, it runs stage 1 with a -31 i have never touched the thing in case i do some damage lol when i next get it set up i will ask what the benifits are and if they tookk it of would it make any difference.

 

it would take WAY too long to explain the benefits ... but it it indeed a valid form of boost control.

basically if you want to adjust the boost you need to restrict the pressure that reaches the actuator... you either do this via putting a restrictor in-line (ala Air-Air) or you bleed off some of the pressure (ala Bleed Valves). Both methods have their advantages and disadvantages.

adjustable srew type bleed valves only havea bad rep because people commonly misuse them. but a bad workman shouldnt blame his tools n all that...

ps i killed an engine by "playing" with my bleed valves :P

 

I run a bleed valve - have done for absolutely ages.

Have no problems with it at all.

 

You should JUST run an actuator, mainly as it will gradually open the wastegate as boost increases, slowing down the speed the car hits full boost.

Nowt wrong with a bleed valve if used properly.

 

i have a bleed valve that was put on by Jamsport but same as James i have never been tempted to change it lol

dont really fancy blowing up my engine
