hi i have a 4x4 sapph running 370 bhp im going to put light blues in soon as i took it to harvey gibbs for a full set up as its maxing out on the greens. and i realy want an external wastegate with screamer pipe does any one have this fitted and how does it sound and perform on the car

 

they work realy well mate as it help with boost drop that happens with weak actuators... but you will need a good boost controller...

i personal love them when running big boost but alot dont they are like marmite lol

im in the process of having the silencer removed from my screamer pipe

 

i love that raspy noise i have to get 1

 

as i said its personal preference but i like it

 

if i was you id buy a 2wd manifold and get a reyland external wastegate peice to fit an external wastegate.

Good thing bout externals is you wont suffer with boot dropping off will just be constant at what ever boost you like, You can buy springs from 7-30psi

 

i thought screamer pipe was like a side exit? someone explain please

 

screamer pipe is a separate pipe coming directly from the wastegate dude, so youve got the deep 2.5-3" exhaust note, then the 38mm-60mm screamer pipe making a nice pitched scream when the wastegate opens on boost

 

listen to the vids above mate

 

so it doesnt just exhaust back into the existing system then? where does said screamer pipe go? or am i missing the point

 

You can make the screamer g back into the exhaust mate, but thats defeating the point as it will be quieter

hope this helps

 

Yes, I did an external wastegate setup when I went over to the gt30 turbo. It was a pricy package all in all but worth every penny. Like these boys said, your boost is so much more consistant, and much easier to adjust and set up (with the help of a decent boost controller).

The screamer pipe is just the pipe that comes off the wastegate, you could vent it back into the exhaust if you really wanted to, but most people will run the pipe down towards the ground and or bend it round to come out the side. Mine just goes directly down past the steering column and exits just next to the gearbox. They sound spot on when you are at full chat.

Reyland is the place to go. Martin hadland. He does all the kit needed

 

ive got one on the cossie ive just brought / which has gt35 and 1000cc injectors and proper management and fully specced engine to suit ....

but the screamer pipe has a silencer in it so aint the loadest but im taking it down to a local fabricator and having the silencer removed ....

so should sound good after along with the anti lag
