    hey guys,
    i've been into mustangs since i was 12 and lost a chance at a gt350 w/ a 351c clone, ever since then i've been hooked. Now i've got a 67 coupe ( very special unique project here for my dad) and a 2003 mach 1 - my DD and kept up well enough to win shows.

    that being said, i've always wanted a cobra to build to be the top rooster in the hen house i live in (AL). i was thinking 3.4 whipple, but decided to look into turbo's now im hooked. :banana: that being said this is a project that will take about 2 years due to an upcoming deployment:pepper:

    so i was wondering what yall's setups were, it's going to be a street DD with some track time... im especially interested in pump gas setups.

    if ya'lls have any info on the hellraiser that would be great to know pro/cons on it as well.

    Thanks guys

    what do you guys want to know? all the kits available should be suitable for street and DD and all of them can be run on pump gas. the amount of power and boost on pump gas I would leave up to your tuner to decide. most people you will find say 17-18# on pump gas. I think all the twin cars you will see 700+ at those boost levels.

    the hellion has a lifetime warranty on piping (all stainless steel) and 1yr unconditional on the turbo's. the wastegates recirculate into the exhaust. a handful of cars did experience smoking, but it was found out to be crankcase pressure being the cause. I am pretty certain hellion made changes to the kit or instructions for this, but I have been recommending a catch can/breather setup and have installed a couple that work great.

    other than that, the kit is a very nice setup. let me know if there are any other questions.

    i've seen some sick numbers from twins, 1 i saw was like 853on pump, and like right at 1k on c16...what does it take to get your car to that level?

    on the hellraiser, i read in a thread ~ 2 months ago a guy here has that kit, and was kicking some ass with it. but i really don't know that much about it, i mean, i read the parts list and everything watched the video, but how does it do in "real world" situations like driving 200 miles and handle in the city. the hellraiser kit is what first sparked my interest turbo's.

    > how does the compound boost work in this kit, and can the stock internals actually handle the stress?

    you can make great numbers with twins and even singles. leave it up to your tuner to help decide what they are comfortable with for boost and power on pump. just because someone did it, doesn't mean everyone can or should and who knows how long theirs lasted.

    the hellraiser is a nice kit, but not something you should put on a car unless you either have a motor built for high boost or are planning on building a motor for it. compound boost is no joke. you can hit 50-60# very easy if you aren't careful. if I were doing it, I would build a motor to handle over 40#. there are people running around with the kits and one of my customers was driving it a lot during the week. the nice thing about the hellraiser with the SC is the low end of it.

    so yeah, stock internals will work, but on lower boost. once you start running upper 20's and over 30's, I would definitely not plan on it lasting long. if you don't plan on building a motor soon, I would probably just consider running the twin kit without sc.

    thanks TRBO VNM some more questions,

    for a twin setup i knwo i dont really want anything smaller than a 57mm setup, but would a twin 67 be more efficient or even 72's?

    the problem with going larger is spool time. the larger you go, the longer it will take to spool up. if you have nitrous, then that will help them spool or an auto. but if you are sticking with the manual tranny and just bolting the kit up, I wouldn't go larger than the 61's. the larger turbo's are capable of making more power, but if you aren't spinning the motor to 7k or higher, the performance will suffer for street duty.

    i want the most i can get, out of pump then be able to put some 110/116/c16 and throw down sick numbers would the 61's do that for me? i would like 9's in the 1/4

    My old setup was a 8.5:1 forged bottom end/stock 01 cobra top end/hp twin 57s.. returnless it made 751/[email protected] return style it made [email protected], wouldve gone [email protected] but it popped a HG..

    New setup is in sig.. basically its a fully built billet 5.5 DOHC w/ race ported navi heads, gt cams, sully lower, hpp upper, HUGE return style fuel system, built 5spd trans and rearend and suspension. itll make 1200rwhp look easy, until I go with a BS3, turbo400, and bigger injectors :)


    edit: oh ya, on this setup Im running a custom TT kit w/ T4 precision 67s w/ t76 wheels, 3 1/2" downpipes, and 3" piping everywhere else.

    If you want pump gas, you need displacement.

    I understand that. but his first setup just says forged bottom end. I could say that about my bone stock motor, so I was just looking for a little more info. plus every tuner is different. who knows how much of it was from tuning.

    See the thing I like about the Hellraiser kit is the use of the stock supercharger. I want turbo's, but don't want the lag time. I would also like to use this car for summer driving and some track use.

    So what I am getting out of this thread is I can use this kit on a stock 03/04 motor, upgraded fuel system(return style) and the obvious drivetrain upgrades. Is this correct?

    I would also like to put down 850+ on this setup and will take the car to get tuned by Hellion if possible.

    Lag isn't that bad if you think about it. Much less likely to break expensive parts, and you're not winning any races if the tire goes up in smoke at 2000 RPM anyway.

    you don't have to have lag with turbo's from everything im reading it's not as bad for us v8 guys....optimal turbo size eliminates this correct? what can the stock shortblock of the termi hold?

    with or without the sc, you can use the car for summer or track use. the lag with the twin 61's will be about 4300rpm or so for full boost.

    you are correct, upgrade fuel and driveline to handle the power. but with the compound setup, you really need to consider a motor as well. if you are looking for 850, I would consider just the twin kit without the 61's and if you are concerned with lag, see about going with 57's. they will still make the power you want and spool better.

    you will have it have a pretty small turbo for no lag or for it to perform like the twin screw or eaton. the 66mm will hit full boost about 3k rpm. but then you are limiting yourself with the amount of peak power it will support. optimal turbo size is important, but again, sizing the turbo with the engine is a big part of it, but also looking at what the turbo can support.

    the stock motor can handle good power. there is a lot of debate about it, but I would say people have made 1000rwhp with it. the nice thing about turbo is you can go from 500rwhp to whatever power the kit can produce in a matter of 2 seconds. as long as you have the fuel to support it. so you don't have to run around town on 1000rwhp. if you are really starting to shoot for 900-1000 rwhp, I would consider building a motor or at least start planning it out.

    lots of good info here... im in the same boat as a ot of guys.
    here's what i would like and need your advice.
    i want to use the stock shortblock minimum of 500rwhp and i would like to be able to hit 700rwhp+ on pump gas, and maybe more on race gas. will the stock everything hold this?

    so how do you judge the correct turbo sizing?

    500-700 is no problem as long as you have the supporting mods and proper tuning. I ran that regularly with my first comp orange cobra. only turned it up higher a couple of times.

    turbo sizing, I really have not gotten into the compressor maps and spec sheets. I pretty much leave it up to the kit designers and what they offer.

    could you school me in some supporting mods, and how to read compressor maps?

    You will be very happy with 57's, lag is very minimal and it's not like you can't make a lot of power with them. You can hit 850+rwhp easy with 57's. 57mm Garrett's are rated for ~550hp each.
