    :rofl: all this time we waited and it looks like that. Just give me a clean design, no excess anything.

    It's not that bad. If anything, it'll keep the supercharger cooler.

    Why does it have a boost gauge? I know the manifold pressure varies according to the throttle angle, but isn't the Roots supercharger a fixed-displacement design? Won't the maximum boost be exactly the same from idle to redline as long as you have the throttle pegged?

    It will be "close" from idle to redline, but the faster the engine spins and the more load on the engine the more boost it will see. I see 2-3psi more in 3rd gear at 6000rpm at 130mph, then I do at 6000rpm in 1st and 2nd with the same size pulley.

    Plus if its colder out, since its "fixed displacement" it will still be spinning the same amount; and unless they have a bypass valve hooked up to limit boost; on colder nights it will boost more then during the day because the air is more dense.

    I know its slow, its a buick regal, but it shows what I mean (dont mind the speedo, it had 23" slicks on the front so the speedo was way off)

    Oh, okay. I knew fixed displacement was the wrong term, but I couldn't for the life of me remember the right one.

    On the one hand I understand the attraction of a "power gauge", which is basically all a boost gauge is unless you're tuning the car yourself. On the other hand, people will be shitting themselves when the boost peak drops by 2psi on a hot day and they'll demand service, which of course will be totally unnecessary.

    You see more boost at high RPM? I guess that makes sense, though it does mean your intake is bottlenecking downstream from the pressure sensor. My guess is you need higher-lift cams and/or a ported manifold, if you don't have them yet. In a perfect world, a positive-displacement SC mated to a positive-displacement engine should have the same boost pressure across the entire RPM range.

    well, for one I had a supercharged tacoma with a modified roots blower... And if you wern't romping on it, it would show vacuum.

    sure, because EVERYONE did this when they drove their terminators in hot weather right?

    Almost all supercharged cars ive seen always have peak boost at higher RPM's, or under more load. (eaton cars, not talking about twin screw or centrifugal)

    Its usually not that big of a difference, .5 to MAYBE 2psi, but it does change. But I see what your talking about and it makes sense, but not everything is perfect I guess.

    Im sure guys are going to do pulley swaps on these, I wont be surprised if GM offers a performance kit through the dealer or something. Then they will be able to make use of the boost gauge. Seeing how much they gained and stuff.

    I doubt GM will offer TOO much while honoring warranty. Also, in for this car not being covered by the 5yr/100k...is the z06?

    You make the most worthless posts. I simply cannot believe it. One after another.

    Where did you get your engineering degree from? Not to many system engineers are 25 since it's a position usually filled by a senior engineer with 20-plus years of experience.

    This should be good.

    I have no idea. I'm just not erring on the side of caution when estimating the average intelligence of potential buyers.

    Where I got my degree is irrelevant. If you have a problem with my post, you can present your counterargument. I won't stop you, I promise.
