    Well i just got my car out of storage and put the intake on ive been working on all winter.(on and off) And im pissed. theres very noticible vacuum leaks. It idles poorly and o yea many many whines coming from the intake. So my question is, the intake has the horns removed because there are BBB's in there and ported runners, Is there any thing special i need to do? i torque the intake to 16 foot pounds so i dont understand why this is happening. please help

    Have you listened to see where it is leaking? You just need one gasket between the butterflies and intake now. Are your hoses worn?

    Not a good idea if you have paint on your intake. Propane would be better in that situation.

    If you torqued the intake properly and nothing is in the way, it should be good. Have you connected all the vacuum lines?

    Did a vac line get cut when you were removing the intake? I can send you some new black silicone butterfly vac lines.

    Problem fixed, thank you guys for the help but im was just stupid when i put the intake back together, i didnt think to look for old gasket material and scrape it off so there were parts that had some bad mating surface. :bonk: :nut:

    wow, couldn't believe the difference a vacuum leak made! 1, I failed emissions for CO when everything else was wayyyyyy below the limit, 2 car idled like crap, and 3 it ran a 14.7 at 95 on nitrous!!! leak found, problem solved, and now the car is back to being way too fast for normal driving.

    If you ran that 14.7 in CO, that is a good time... That would be in the 13's near sea level, provided you had traction.
