i heard one of the cadillacs for 04 was coming with a supercharger. is this true? and if so can the supercharger be taken off and put on a 94 cadillac eldorado with a northstar?
No, not true unfortunately. You might be thinking of the IMAJ concept car. That is supercharged (425 hp) but is not a production model. You might have also heard about the CTS-V which is a savage machine in it's own right (Z06 Corvette engine putting out 400 hp). Originally there was talk of putting a supercharged northstar in the CTS-V, but GM scrapped the idea when they found out the northstar wouldn't fit in the CTS engine bay. The 2005 STS will have a "V" version that will be twin turbo.
People have been working on a supercharger for 93+ 4.6 northstars for years. The project seems to be at a standstill. Computer issues. Go to caddyinfo.com to find out more.
no ones taken time to figure out the computer issues, want a supercharger, if you have enough $$ its not a problem, get a stand alone custom built ecu. were not talking bolt on $3,000 hp, i know i saw somewhere someone had a supercharged northstar deville. but your talking mega $$$ - don't hold your breath for a kit.
Computer issues? I find that kind of funny seeing as people are dropping turbos and the like in Saturns for chrissake.
Well, Saturns need all the help they can get... but that's another post. There is a twin turbo kit for the 4.6 northstar, but it's for sand cars only. The piping won't fit under the hood. Computer problems seem to be the reason why the project is at a standstill. Don't ask me why, it's all Greek to me.
The computer calibration issues are basically what is stopping most of the supercharger projects. The mechanics of bolting up the supercharger are not the difficult but the cal changes required to make it run right are difficult. Plus, there are several different generations of Northstars to deal with...the 93-95 had speed density systems, the 96-99 were the MAF with OBD2 systems that are much more difficult to hack into and then the 2000 and later systems that are a completley different control system that is very very difficult to hack.
The other things making the Cadillac more difficult is the complete vehicle integration of the control system and electronics. It isn't enough to just get the engine running correctly with the supercharger. The trans is controlled by the PCM also . The production PCM cannot be just ditched and an aftermarket controller used as the rest of the car will freak out not seeing the production PCM operating.
Saturns and Hondas are much simpler cars and the PCM's only control the engine so they are easily replaced with an aftermarket controller that will accomodate boost. The Cadillac systems cannot accomodate this.
Bbob would be pissed... to think that the engine was developed in the late 80's early 90's ... and then to say its a piece of crap engine made in the 60's! When this engine probably has more electronic capabillity than the pos COMPUTER youre probably using Koz.
Northstars were made to be high-performance, and are high performance. You could practically transfer a n* into a sports car right now and it would be killer... oh wait its been done... the XLR, the Cien etc. etc.!
