1 Bar Boost Spring 930?
 

Does anyone have the part# for a 1 Bar boost spring for a 1989 930? Or know of any other options that may be available.

You oughta ask the guys at Rennlist.com----- Turbo 911 Forum. It's a very active 930 site.

Or check our the 930 page on pelican... I would say it is actually more active than rennlist these days.

I think you can order the 1 B pretty readily. The two alternatives I could think of would be to swap out the stock WG with a TiAL unit or install an electronic boost controller. The EBC route works very well but you have to be very careful as it doesn't take but a slight adjustment to get to 1 B from stock. Too much juice and you will have a hand grenade on wheels.

I have had both a TiAl on my car as well as a EBC. Personally I prefer the EBC and will be selling my used TiAL.

Thanks for the ideas I will check it out.

1 bar might ping. mine did. .9 worked.
