bypass valve for novi 1000

i need one for my 89.if can get one that makes noise that would be great. any suggestions would be great...thanks

The one's that make noise are typically for turbo applications and are vented to the atmosphere, whereas w/ a supercharger you vent the metered air back into the charger inlet pipe. Most of us use a Bosch bypass valve, you can find a couple sources and the part numbers in the post titled "New Member's Here", there's a link there on bypass valves.

great thanks for the feed back

No problem, be sure to search around as the price can vary greatly. If you live in a city of any size you may be able to find it locally.

i keep hearing about this saab part that is used as a bypass valve does anybody have a part # or know of a place to get it???

Crap, I just tried the links in the thread I recommended & they are dead. I'll drop Ian a line and see if they are retrievable. In the meantime, I'll see if I can dig up the part #'s for ya.

Links are fixed & here's the part#

Bosch part #0 280 142 108

There's a few recommendations for on-line sources in the thread I fixed.

i tried several places in town including the saab dealer with that part # and none of the ones i had were good i tried 0280142108....0280142110 and no luck...please help

I am using this Bosch bypass with my Novi 1000 part # 0 280 142 110 and it works great. I purchased my bypass from expressautoparts.com Ph # (212) 590-2448 The bypass is for a 2000 saab; 9-5 turbo V6. Hope this helps you out.

Ok 007, I searched for 30 minutes, these damn things have gone up considerably. I paid less than $25 from expressautoparts a little over a year ago & now it's ~$50

Try this link, it was the cheapest I could find:

5150 LX I paid the same price for my bypass from expressauto parts. I guess when a lot of people started buying the Bosch bypass they jacked the price way up.

That's the only thing I can figure, more than likely some guy cashed in on the deal & bought a bunch, then sold them for 2x's what he paid.

Someone posted a while back on another source but I tried like hell to find that link to no avail.
