Just Fitted Hks Sqv, Couple Of Differences?

[cal_type r]

Hi guys.

Just fitted my new HKS V2 Dump Valve, some peice of kit, very happy aswell.

Just a couple of differences when driving you might be able to clearup? I had a blitz one on before and when the engine was on decent overrun you could feather the throttle and make the car pop and bang but now it wont do it, the throttle feels just that bit more responsive. Also with the blitz there was a bit of tuirbo chatter aswell as the blow-off from the valve on lift-off, now its all from the valve. Lastly it sounds like you can hear the turbo boosting through the bov itself! When the car comes on boost im 99% sure theres a drawing whiny noise coming from the SQV. Its 100% connected correctly just wondered what you think?

Cheers

Theres a spring that can be loosened and tightened. If its tight you will get turbo chatter, as the valve isnt fully opening and sending the air back into the fins of the turbo. The pops and bangs will be coming from the overun induced by the knock on effect of a tight spring.

I was told by AWD not to mess with the spring setting as it is factory set

Im not overly impressed with my SSQ either.

I thought there would be more of a WRC style "chirp" off it?

Dont get me wrong, it is loud, just not what i was expecting......

just be glad its working , mine broke sent it back to the supplier they sent it to hks and they have been chasen HKS up about it for over a month now even the supplier is saying its out of order how slow HKS are when something goes wrong , a think its shocking after the money there parts cost ,a wont be buyin anything else from them again

What one do you guys suggest then.

HKS rubbish, Blitz are the same i thought. Just brands really....

So what one is the best functioning one.

On the Mr2's we came from it was best just to run the standard one. If you wanted the noise just take the recirc pipe off. HKS seemed to work ok on them but the Blitz were rubbish.

Its interesting cos the spring in the blitz one was backed right off as slack as it would go and i was still gettin a good load of chatter.

Im very happy with the noise, do miss the bang pop though, am i right in sayin that the purple insert is the loudest one to fit?

Disapointed to hear about bugeye 29s not working, it is ridiculous considering the price of them!

At the end of the day, its just a valve. I would suggest not messing with anything on your car if you dont know what your doing. Most people will have a play with the spring, but not realising that with every adjustment the car needs to be remapped to suit its new parameters.
