    Installed intake

    Hey, I just installed that intake my cousin gave to me, it looks nice, but after installing it I noticed that my engine compartment needs to be cleaned out. You guys may not believe it but my 97 deville has got a little better throttle response. Have you ever looked at that stock box?? A tiny little hole is the only air inlet. If you guys have any questions just throw at me. I can give you the guy he bought it from. Also is there anything I have to watch out for when washing out the engine compartment?

    Don't drown the coils, ICM or the alternator. You might have to blow out the plug wells if too much water gets in them and it starts missing. Personally, I was never too careful.

    Regarding the air box, our old Guru (a GM powertrain engineer) told us that the intake was designed to deliver all the air that the Northstar needs at WOT. If you stop and think about it, why would they build a world class performance engine and restrict its output by something as simple as restricting the intake opening.

    Re: Installed intake

    I am going to put an intake on mine to.I seen a lac like mine wit a volant intake,hooker headers,bosche titanium 4 spark plugs,corsa exhaust,took off speedlimiter, and put new chip. He says it feels WAY! faster than stock, and that they haven't messed with any computer so far after having it on 6 months.So i plan on doing most of the same except for air filter(i'm going k and n)...I know ranger is very very very knowledgeable (don't know if i spelled that right) when it comes to the northstar or any cadillac. But if a northstar was really tuned to the max at factory people wouldn't make leagal aftermarket parts that show improved hp/tq.

    Re: Installed intake

    I see your point ranger, it is a class leading engine, but there are always alternatives, and new technology is coming out every day. My car is a 1997 and I am sure that the filter designs and intakes now are better than before. In 1997 it had the best parts, but even then, they have to make the equipment as quiet as possible, which results in loss of power.
    Does the old guru ever come on anymore? It'd be interesting to learn new stuff from him. I am going to get into engineering after hs , work for GM.
    Are bosch plugs bad or something??? I have seen a prototype chip, but none for the deville, they are too expensive for the little horsepower. All I want to do to my car is new mufflers and fix some bumps and bruises the car has.

    Get the Hooker part# for those headers.

    Do you mean "claim to show" improved hp/tq?

    They claim more than they show, but there is improvement.

    That made me laugh out loud. I love it when I go to the parts store and people actually buy some of this crap... Especially the BS bosch plugs. I think in the near future, I will market a new spark plug with six instead of four and sell them for fifteen dollars each.

    I don't mean to sound like an a**hole, but do you have any idea what you talking about?

    Hooker does not make exhaust headers for the N*. No one does, unless you count a jig that you fabricate a set on by yourself. If it's a Deville '96 or older there is no "Chip" and you can't remove the governor. I just hate it when people start spouting things they've heard from people who claim to have done things that are impossible, and have people believe them. I have no doubt that with a little finesse you might be able to get one of their block hugger headers to kinda fit, but no one manufactures stock replacement exhaust headers for these cars.

    Re: Installed intake

    yes hook does make custom headers for some extra $$$ i've called about them already and the governor chip can easily be removed from the mechanic i go to for 112 bucks(he's been working on Cadillacs for more than 20 years and thats the place where the dealer i bought my car from sends theirs.)Said there should be no computer error and the hp/tq gains were on a dyno.plus it was chip made by fastchips.the gain with all the things wasn't all that much but better than stock.It was 24hp gain and a 16tq gain.
