recirc questions

[Cam]

hi all new to the forum and mods to turbos so bear with me if i ask questions which you have all seen before ,i have tried the search but not been able to find the answer i need .i have a 2000/01 v70t5 auto which is standard apart from a small mod i was told about from a swedish volvo tech who worked on design and research stuff ,so i want a bit more sound from the car i had a 850 2.5 10v which with a filter sounded sweet ,the t5 is quiet so i know an exhaust is 1 answer but i also fancy induction/turbo noise/chatter.i have been told to forget the dumpvalve way but poss go blanking plate on the recirc or m.r.p s mod ,but i have just read about poss damage to the turbo with just blanking it off ,is this the case or not ,filter kits which is best any diy mods to the box

The whole Will it/won't it damage the turbo is an ongoing debate mate and best left alone lol.
An easy one is to get a big cone filter from Ebay for about a fiver, take the lid off the airbox, remove the maf from the lid, fit the filter to the maf and rest it in the bottom half of the airbox. You'll get some nice wooshy noises, especially if you remove the soundproofing from the bonnet (5 minute job)

Watch from about 1:30...

Beware though your fuel economy will drop serverly due to you revving it more to get the whoosh hish sound, but as a wise person once said to me forget about Miles per gallon, its all about the smiles per gallon.

I'm not sure on the blanking plate stalling your turbo tbh, can't see Martin putting one on his t5 if it was gonna screw it up. I'm pretty sure his is the original & has seen over 200k. Blanking plates are cheap enough & me personally would recomend forge Motorsport.
As for the noises, an induction kit will make your chatter louder when your plate is fitted but I have drilled my air box & removed the sound deadening under the bonnet with a plate.
For the box I can't help I'm afraid.
Sure someone in the know will be along soon though. Lol

[M-R-P]

Yep - mine has 203k and the original turbo. I fitted a series of valves to lock the waste gate closed but I had it switched off most of the time in case it caused undue wear.

[Biff]

Sorry mate, by time I'd started replying you'd replied.
From what I'm led to believe mine isn't affected by it but I looked into it before I bought a plate.

[M-R-P]

Like I said, the debate is still ongoing as to weather or not it's harmful to the turbo but there's also the stress to the rest of the system to consider - Intercoolers can split, pipes can pop off or split. Running standard boost pressure should be ok but I'm running an MBC and occasionally hit 16-18 psi.

[Cam]

So running standard boost with a blanking plate should be ok or just running a filter will produce a nice noise

[M-R-P]

If you're on a budget, do the cone filter thing first and I can show you how to make the rig to lock the waste gate shut if you want.

Will do thanks

I just have a cone filter on this and standard dump valve

Tuning for a reason or modding just to make noises? LOL all seems a bit pointless.

[M-R-P]

Just like changing wheels or tinting Windows or even detailing. It serves no purpose to performance but we do it to enjoy the car more. Hardly pointless.

Agreed, surely the whole point of modifying or customising is to stand out or break from the humdrum of everyday cars.
It's not all about flat out & max power for me. I think it's great people turn they're heads as I'm chattering away. Lol

That reminds me, I must get a video of the new "bark" I get from the recirc when I dump the throttle at 6psi

[Nutternick]

I was surpised mine was as loud as it is with just the filter changed

[M-R-P]

Says the video is private...?

[Nutternick]

Try viewing now should be working

[M-R-P]

That's better

I'll try getting one of mine in a bit

"bark" if you want something that "barks" get a 850 run it to 1/2 a bar in second and let go of the throttle
