    Yeah still need some long tubes and a tune then I will plan on graduating

    I will need a new transmission/dif if I keep going. (I can feel mine getting weaker) Which I fully plan to as long as I continue to have money to support it. Have also considered getting a 3k stall or something of the sort. Not sure how much I want to cam as I don't really want to loose my luxury...Well see when that road comes though.

    I'm taking my roomates srt8 to Tracy next Friday to install headers. Should get it up to almost 600to the crank and hopefully have the TB to take home to my car.

    Re: Any update on that RX throttle body...

    I figure my transmission has over 100,000 miles on it. Even with a recent flush/filter/fill service and an external cooler, its only a matter of time before it grenades. I think the exact same thing about my differential. The transmission choice is obvious, for me. Built from scratch Level-10 Bulletproof 5L40E with, like you said, a 3,000rpm stall. But that is $3,500 I really do not want to spend until I have to.

    The cheapest differential upgrade would probably be a V1 pumpkin. All the V1 guys who modify their engines upgrade to latest and greatest version of the rear end. That should leave plenty of first generation diff's laying about for cheaps. We CTS-Jr owners would have to go forced induction just to make the V1 baseline, so we do not have to worry about blowing up any Vee-car rear ends. Plus, that gives us 3.73 gears... fun.

    Re: Any update on that RX throttle body...

    As good as that sounds, I can't justify spending $3500 right now either lol. I will probably just do an upgrade rebuild when the time comes. Hopefully not for a while though. Wonder how hard it'd be to get an extra gear in there..6 speed auto would def be nice.

    I never gave thought to the V dif. That is a great idea really,, cheap and semi-strong..BUT, would you need to get the whole rear axel to go with it though? or would it be plug and play? Atleast I'd know I could beat on it without breaking things hehe.

    How are you liking it?
    Hey, look! I found a thread that was specifically about the throttle body, and it was active in the past week!

    How are you determining that without seeing what Tlorenzen's AFR, knock count, timing, etc looked like before and after? He's making more power by getting more air and fuel through the engine, as is the case with porting the heads or long tube headers or just about anything else. It shouldn't be any more or less safe without a tune than with other, more aggressive mods.

    Based on what you posted in the original RX throttle body thread, I think that 50bhp gain is a bit suspect...

    Producing crank horsepower number from a chassis dyno is pretty sketchy, particularly if you have no baseline run upon which to base assumptions of drivetrain losses. And even if you knew the stock drivetrain losses, they're not linear as the power output of the engine rises - from what I've learned over the years, the drivetrain losses (as a percentage of BHP) go down as BHP goes up.

    I am curious why RX would have their dyno displaying BHP. There's a reason basically nobody does that.

Just have to be willing to have it done.
    If I were you I would save yourself lots of time and money and skip the built short block. Definitely skip the cryo - I don't know what one would want to do that for. It's highly unlikely you'd see any notable gains from balancing and blueprinting, as modern engines are much better in that regard than older engines. The same is probably true of knife edging the crank; with all the focus on maximizing powertrain efficiency (to get those all-important good EPA mileage numbers), the factory will want to minimize windage losses so the crank is probably already good.

    Go to town on the heads - as long as it's done properly, that's going to give much better return on the investment.

    Setting things straight! Honestly, I'm not really sure why the dyno was set to crank numbers..I thought it was kind of weird myself, but I'll ask him when I go back over there and see if can get that fixed. We did have a computer plugged in and o2 sensor in exhaust if that means anything.

    Welcome to the forums. Glad to see we have another member committed to Tracey's throttle body.

    AAIIIC,
    Machining the heads and swapping cams are something I really want to do. I just emailed MACE to see if they offer any upgraded valvetrain components. I already know they offer a camshaft kit that is designed for use with the stock valvetrain, but if I am spending the money to P&P my heads and swap cams, I would like beehive springs and higher ratio rockers and cams ground to best utilize the new gear. So I am seeing if they offer such things. They also have a die-hard double row timing chain kit that I am interested in. Hopefully they get back to me with a favorable reply.

    Update: Got an email from Tracy today. Unfortunately, he isn't sure if the TB will be done or not on Friday. I will call VMAX tomorrow to get a better one

    Just talked to vmax today. The first pass just finished and hes not happy with how it turned out. Said something to do with epoxy idk. But anyways it isn't ready and will, unfortunately, still be a while. Sorry for the bad news as I want this back in my car as much as you guys want it haha. Will know a little more tomorrow.

    I would rather wait and have it be amazing, than have it now and have to deal with any issues.
