How frustrating.Nothing from CHRfab will work on a stock Northstar still residing within a Caddy. The parts they sell are designed with work with standalone computer management in vehicle like hotroad, sandrails, ect. Basically all of there stuff is for non-oem or stock applications. Granted you could put it on there, but the engine wouldn't run very well, and you'd end up with a lot more problems than you want.
This engine poses the biggest challenge I have ever faced from a mechanic's standpoint. In my previous posts, I discussed my involvement with building high output small block and big block Chevy, Ford, and Dodge engines. Building power in those engines was a relatively straightforward proposition. Even a 1988 5.0 L Lincoln Town Car posed no serious challenges in building high horsepower. I have owned a few "modern tech" performance vehilces from BMW (the M5 was a nightmare from a reliability stand), but I kept returning to the Cadillacs and Lincolns because to me, they are the unsurpassed iteration of the quintessential luxury car. I like my bench seats and room to stretch out! Tim Allen Design's 400 hp DTSi notwithstanding, the traditional rules of hotrod application don't seem to apply in this case. What gives Cadillac? Why can a N/A SOHC Ford 4.6L V8 be built up to 300 hp with bolt ons, but nothing can be done to the Northstar?! There has to be something that can add 25 hp to that engine.Yeah no one wants to make anything for our Northstars. Every time anyone tries to get one of these other companies to help us out the company basically tells us to pound sand.
I've been looking at the intakes patterns on a 5.0 coyote and the pattern looks the same but I dont think the bolt pattern is I've got a 2006 buick lucerne with a 4.6 northstar and the intake has a boot that connects it to the throttle body so why wouldn't a tubular intake be made to up the performance or sheet metalI was looking at the intake manifolds on CHRFAB.com. Would any of these fit on the 275 hp northstar and give it any noticalble power improvement?
