Brad Posted April 8, 2005 Report Share Posted April 8, 2005 Was at the local dealer the other day and started reading the book on the 2005 Devilles. I noticed that the base and DHS models retain the same Northstar as in years past which is rated at 275HP and 300 lb-ft torque. However the DTS is now powered by a 290HP and 285 lb-ft torque engine instead of the usual 300HP and 295 lb-ft torque model. Anyone know what prompted the change? Also I noticed that the engines are now called the Northstar NHP - what does the NHP stand for?

STS Scott Posted April 8, 2005 Report Share Posted April 8, 2005 I noticed that too and was wondering the same thing. It slipped my mind though. Now you've got me wondering again! Hmmmm....

SGT.ROCK Posted April 9, 2005 Report Share Posted April 9, 2005 Maybe it was detuned to run on nasty 87 octane. I think they should make all cars run on 93 octane and do away with 89 and 87 octanes. Link to comment Share on other sites More sharing options...
Brad Posted April 9, 2005 Author Report Share Posted April 9, 2005 Thanks Guru! I knew you could sum this one up in a hurry. Brad ---------------------------- 1999 Deville Concours [sOLD] Blk/Blk w/gold package Link to comment Share on other sites More sharing options...
JasonA Posted April 11, 2005 Report Share Posted April 11, 2005 Maybe it was detuned to run on nasty 87 octane. I think they should make all cars run on 93 octane and do away with 89 and 87 octanes. <_> All 2000+ Northstars are optimized to make 300 hp on 87 octane fuel. Nothing is gained by putting premium in a 2000+ Northstar vehicle. And really, you can put 87 octane in a pre-2000 Northstar car for an imperceivable (like, less than 5 hp) power loss.
