    wow, um, how about both at the same time? no? not really? darn, well for now
    i too like Turbos and am getting one day. I like the lay around and wait for it effect. I like it when he thinks "haha, i won already", then BAMB!! right in the kisser! Sounds kinda cool too. so I vote turbo

    yeah, do it! i've seen many twin-charged cars work decently.
    a couple things i read in this thread bothered me.

    "headers won't work on a turbo car" of course they won't because they are replaced with exhaust manifolds with flanges for turbos. wtf?

    LAG- the way a lot of you seem to think of it indicates you have never been in a turbo car. my experience with turbo cars has been i4 and i6 smaller displacement. (2.0 and 2.5) even those cars with larger turbos dont exhibit the kind of turbo lag you guys think is present on big v8s with properly sized turbos.

    "single turbos are usually better" not really. for max hp and power under the curve TT are better. more expensive and complicated, but proven in many applications. drag racers don't seem to care about anything but the peak HP number... go figure.

    "boost is boost" really? so 10psi from a garret t25 is the same as 10psi from a mitsubishi t78? no, it's not and i'm shocked granetelli didn't mention this.

    "BB reduce lag" not entirely true. BB does nothing over conventional cartridge bearing housing turbos as far as intial spool. nothing. the big advantage is in transient response. (on/off throttle)

    which brings me to.... how either system behaves at a race track. transient response is a non-issue for most superchargers. all that matters is what rpm youre at. a turbo will be on and off boost as you modulate the throttle. this doesnt matter if all you want to do is drag race. for everything else it matters .

    i dont and have never owned an american car with a v8. i want to though. it just suprises me how ignorant many people here on this board are. i.e "turbos or for the rice, heeyuk yuk"
    i think that reality is that for all out power and speed turbos are better. that being said there are still many reasons to go with a supercharger. linear boost production is attractive to many as it ends up still "feeling" n/a. (i myself like this)

    the backpressure argument- silly squabbling. with no exhaust whatsoever any setup will make more power. at the cost of literally a couple ft/lbs of tourqe in some instances.

    once we can all agree that turbo is best the internet battle over the intracacies (sp, wtf?) of turbos can begin. (ex mani design, internal/external gate, twin scroll worth it?, VNT turbos, etc...)

    I've seen many single turbo kits that outperform most TT kits on the market.
    Most single turbo applications turn out higher peak rwhp and work more efficient than asynchronous TT. hint. see what a single turbo can do to a Supra for example.

    hint. see what kind of turbos the top hp supras have.
    a really high peak number is a cute trick, but REALLY big single turbos actually pay the huge lag penalty. 1000whp from 8-9k rpm is nice, but not if it's coupled with 250whp at 5k rpm... you would think that on a v8 board a broad powerband would be more valued since v8s specialize at this, unlike the revvy 4cyls...???

    sequential tt is cool for a great power band in a lower hp application. not really necessary these days though.

    heheh, that's why for street legal, one of my friends is putting a single turbo 600rwhp easy on his supra.. the TT setup got him to 450rwhp. if you're talking drag race 800-900rwhp anything is possible but for street legal single can outperform in most cases the tt

    you are wrong. tell your friend to try twin hks 2835s. thatll smoke well past 600whp and make more power down low than your buddies single turbo.
    you have no idea what youre talking about.

    ok, since on the topic of twin-turbos, what happens if you have two different sized turbos? One big one and one smaller.
    What will that do to the powerband? Would the smaller one pick-up first and then the larger pick-up where the smaller one left off?\
    Sounds like a neat theory anyway. im sure ill get slapped around for this one.

    heheh... you may have some tech point but it's opinion based, I doubt you tried the highend tt package vs a single turbo highend one. but you like to disregard my point because you feel you are right. that's your opinion but don't make blanket statements. you smell like an ignorant then.
    and yes I have an idea what I am talking about, it may not be what your opinion is, oh well.

    We have fitted a single turbo to one car, no lag goes hard but a pig to fit.
    Just finished a 402 ci with a Vortech V7YSi with 15 psi and it rocks.
    I'd pick a blower PD or Centrifugal depending on when you want your power.

    noice, I saw this video of a silver color Supra 1200rwhp or so this guy from Houston, single turbo, damn the guy was soooo freaking fast, he did 8.5 in 1/4.. 170s trap speed. omg!

    1200hp and only 170mph - that car must be real heavy - like 3100lbs

    I am re-voting Turbo AGAIN. A positive displacement can't even come close. The centrifugal is still a great choice but the turbo is the king of torque. My Vette speaks to that. I tried a huge procharger. While it made like 800 it was loud and flat down low as compared to the litel twins



    only 9psi and REAL pump gas



    15psi and 100 octane

    Speaking of wheels - I want to get wheels for my WS6 - I am looking for Z06 type. I hear you can stuff a 17 x 12 in the back is that true and where do I buy rims at the best price

    I would prefer a turbo car over a SC because I do alot of road course. My Shelby GLHS (2.2T) has a nice powerband 3500-6500 rpm (300lb/ft, 2300 lbs) perfect at the track with no power loss like a SC at high rpm.

    SC cars are great on the street, step on it and bye! My wife has a SC Mini Coop and the 1.6l feels like a V6.

    For these LS1 cars, I love em NA. My Z28 at the track is so controllable and reliable I would only do NA mods. I only pop the hood at the track to check the freakin power steering fluid (I need a better cooler).

    Once you start to boost it, something always comes up IMHO.

    Anyone out there able to do 30 minute track sessions WOT in the summer in a boosted F-body?

    I love to see the dyno sheet! And to your Vette, the only thing to say is "Holy Crap Batman!!!"

    yeah they weight about 3400 stock, not sure what he did on the weight,
    one of my friend actually met with him on a Supra meet here in Dallas.
    my bud has a 94 TT Supra 390rwhp. he said it must be the slowest Supra around cause everybody he knows runs single turbos and stuff, going at least 700-800.. eheh more money more boost

    I personally get a rush from both systems, and both can be tuned to aquire tremendous results. Yes, turbo's seem to do much better overall on the dyno, but then again I've seen supercharged systems spank turbo charged systems making significantly more horsepower than them at the track. Definitely boils down to personal preference, as far as the "simplicity" of the install is concerned, for one. Both systems can propel our street cars to sub ten seconds in the quarter mile, and that is a damn fast time for a freaking street car. I'm personally looking into the Gale Banks TT kit for my next project car, a Motown inspired Twin Turbo 454 small block, Holley Stealth Rammed, '89 Iroc....
