: I see a lot of posts on supercharging a Northstar

I thought the Oldsmobile Aurora came with a supercharged Northstar. Seems the mechanicl parts would bolt right on without much modification and if need be, seems the onboard computer could also be interfaced.

Has anyone looked at using an Aurora supercharger?

Sorry for wasting anyones time, a friend of mine mentioned he had a Supercharged Aurora and said it had the same Northstar engine as my STS. I should have checked first but I took his word as being good. It apears that Oldsmobile did offer a supercharged Aurora but is was a 3.8 V6, sorry fellas.:banghead:

No, Oldsmobile never offered any sort of supercharged Aurora. They either had the 4.0 Northstar V8, 250 hp or the 3.5L 215hp V6

Your friend must be retarded. There were quite a few projects for the Roras but they all failed because the PCM could not be hacked. Physically its capable to have a blown 4.0L but nobody can program the computer to handle the boost.

There was a turbocharged Olds back in the '60s. The blower was made by Garrett, it had the most complicated waste gate controls known to man and included an anti-detonation fluid injection system. It was a contemporary of the Pontiac Tempest and the little Buick. Thus the BOP 215cu.in. aluminum V8.

Yeah ^^ That's the jetfire. Cool idea. It was about 10 or 10.5:1 with a 6psi turbo. Aluminum block 215ci. Used water injection to cool the intake charge. And IIRC side-draft weber carbs.

The Oldsmobile Aurora never did come with a 3.8L V6 engine. Starting in 2000 or thereabouts (someone can correct me please) with the 2nd generation cars, they had the choice of a 3.5L DOHC V6 (Shortstar), or the 4.0L DOHC V8 (Northstar). The Aurora, or any Oldsmobile for that matter, never received the S/C 3800 engine (if that's the engine to which your friend was referring).

Olds 98 had the SC 3800.
