Dump Valve

[GT4 BOOSTER]

fitted this today , thanks to KEN sending me the hose. i just gotta turn the grub screw tomorrow so i get the psssssssstttttttttt sound that i'm happy with

it only took 2 days to get here all the way from Malaysia

[Chris.S]

how much was that and is it worth fitting one

59-95 plus delivery, its no different to the standard recirc bov in terms of worth , it just sounds good when you change gears and it dumps.

Looks excellent matey. Good price too.

I especially like the looks of the outlets.

well i finally got some sounds from it today . i had to re route my boost gauge pipe though as it was bleeding too much air from the dump valve and i was getting no whooooshhhhhh at all. Now it gives out an allmighty WHOOOOOOOOOSSSHHHHHHHHH at every gear change ,i have still got to route the boost gauge somewhere , the only place left i think is the spare pipe behind the manifold , and with hands like shovels its not gonna be easy .

[daktari]

I don`t know if your layout is the same as mine but your better of going in from the righthand side of the engine as you look at it. Slightly more room to get your shovels in.

is that where yours is teed into martin. i teed into a pipe directly from the manifold to some kinda valve but my gauge is now vibrating like hell as if too much air is in it now ???? the right hand side looks pretty good to me , fiddly but good.

Yep. It`s an 8mm tube with a rubber blanking cap on mine. I just used a 8mm - 4mm reducer and that was that. No problems. Originally i had it teed into one of the vsv pipes, but i had the impression it was under reading. At least you know that you`ll have an accurate reading direct from the intake.

[Daz_s16]

The gen 6 has a recirculating one fitted as standard. The gen 5`s didn`t. Tho most do now. :D

Booster - I cant believe you actually want it that loud, on my Astra it p!$$ed me off when I had to drive it daily. Changing gear in traffic was embarrassing, personally I found it was making people turn heads for the wrong reason. Mate also had a Saph and he thought the same. It was only when I started using it for Track days that it felt like it belonged! Ohh and obviously on a weekend cruise its a great addition to the noises' of the countryside!!!!

Marc. Roughly how loud is it in comparrison to say a :- Sonic boom??? or Hedghog farting??? The Blitz used to be fairly mellow with the filter, but it`s got the horn now....... Ooops, Sorry, Horn fitted now. And i would liken it to compressed air being expelled to the atmosphere at high pressure.

The R2D2 is the second loudest bov going and the noise it makes , tis kinda like a WOOOBOOOOOOWWWWW.

Had Dawesy's Blitz one on until it arrived and definately prefer the R2D2

:D I like the sound of that.... No pun intended.

what ken said.

its like when a tyre fitter squeezes the tyre from a steel rim , and the air explodes out. it blew my hand out the way when i revved the engine setting it up. Frightened the life outa me.

nice one booster... a dump valve is a MUST on a turbo car :D
