HKS SUPER SEQUENTIAL DV

[irish al]

Just fitted one of these to the car.

It is quiter than my baileys DV12.

Does anyone know if its adjustable to make it louder ??? the instructions are in chinese

st3ph3n i know u have got one, is yours loud ?

Its more like a whistle rather than a psssssssssshhhhhhhhhh

[jasonb]

You can adjust it but i am not sure how to but watch out as to much tension on the spring and you could

cause you turbo to stall and damage it

[dan_jess]

They have changeable inserts, purple, silver and gold, gold is the loudest

My m8 had the purple insert when he bought his sqv and u cud hardly hear it. Bought the silver 1 and its really quite loud now, not sure how much they r tho

[st3ph3n]

WRC No 1 told me how to adjust it, but I forget now. I think there's a wee bolt on one end you can adjust.

Is there not an issue with these vta d/v leading to damage to cylinders?

To some people sounding like a double decker bus is more important than thinning out thier oil and risk picking up a bearing.

Can it lead to that Grant?

Fooook that, safer with recirc

he thought of sounding like a double decker bus appealed to me but after reding various post on here i dont think ill be bothering

another stupid question whats the difference between a blow off valve and a dump valve

[the squiggle]

Do a search for Borewash on Scoobynet or google

The big ends on an Impreza are smaller than a Citroen Saxo and have to deal with a lot of horse power each

Oil quaility and viscosity are crucial in providing a compressive barrier in the Big End shells. Thin the oil out and the barrier that prevents metal to metal contact at the bottom of the power stroke could lead to spinning a shell in the Big End housing

If you do have a VTA then increase the frequency of your oil changes to compensate and if your oil smells of petrol when changing, fit a recirc dump valve

Basically both one and the same

Some times an external wastegate is referred to Stateside as a Blow off valve or Pop off valve

Spose

There would be warranty issues here as well eh ?

cheers for that grant so basicaly in a nutshell(nuts squirell get it) should be left as is .

reading on here about induction kits aswell would it be right to say a good panel filter is the way to go aswell

[the squiggle]

Fitting a cone filter to a std ECU will richen up the mixture and confuse the hell out of the MAF

The extra richness will negate any usable power gained from fitting an induction cone

On a std ECU a free flowing panel filter such as the APS or STI one will give the best gains

ok mr squirrell thas all the bad bits about dump valves now tell us the good bits about them they all aint bad.

[the squiggle]

They sound awesome and make your car sound like a full blown rally car with all those whistles and chirps.

I have run with Grants suggestions and will change my oil (with Motul) more regularly......I have the Turbo XS RFL dump valve and it sounds IMMENSE. I figure that if Jools is running one on his car then it cannot be too bad as long as you take the g-mans advice....

Picc of the daddy - different sounds to HKS ( which i really like) but louder ......

I actually thought of selling it to fund other mods but my fiancee demands that I keep it ( unusual for a non-petrolhead )

If you blip the throttle on a "heel toe" gear change on approach to the KH hairpin ot sounds like s3xual chocolate

Nice dump valve Carl

Just got myself another one off ebay to fit onto the fmic piping.

Sounds superb!
