A lot of people are going the paxton or procharger route because the boost doesn't kick in until over 3k

ugh, that's a loaded question lol. twin turbo is less constant stress on motor as well as more hp per psi due to no parasitic loss but then you have turbo lag and they create a lot more heat

twin screw power on demand, use more gas, constant stress on motor, parasitic loss and some heat

centi, out of boost until higher rpms, less heat, will still dtive like stock at low rpms

Re: Twin turbo or twinscrew supercharger???

personally I love the twin screw... but due to cost in the long run I may go centri, especially since it's a dd

Re: Twin turbo or twinscrew supercharger???

I agree, as long as you can put all that power to the ground... wider wheels/tires, ucas, lcas are all a must to put down the power, other things would be helpful as well

I think it's a great blower but pretty pricey. If you're looking for a range of power from say 550-700 the roush is an amazing blower for a lot less money. If your plans are to build a crazy fast track car the kb offers more potential but the roush would be good for what about 95% of us are looking for.

800+ hp on a Hellion TT '13 Boss...not mine unfortunately.

Not against any of the above mentioned options and personally would go Procharger on my '13 GT since I used to live 10 miles from them...

Re: Twin turbo or twinscrew supercharger???

You have quite a few choices there, both have their Pro's & Con's. Hellion makes a great twin turbo system to my understanding and I believe they have a bolt on kit out right now or it may still be in R&D. Twin screw, roots, centrifugal supercharger systems are all great and very reliable. The most common one being the twin screw design, it is quite efficient but not to say the other two supercharging systems are not as well.

I shall forewarn you though that "Not all boost is created equal!", just remember that saying. A turbo kit does require a bit more work to install, while most of the time a company's supercharger kit is just a bolt on and go type deal.

Be prepared to tune your ECU afterwards immediately, otherwise there will be consequences to leaving it untouched running with a faltered Air-Fuel Ratio.

Yes, to the post much above me that turbocharging does promote better fuel-economy. I have noticed this in a couple of different cars compared to supercharging. But that being said once again "Not all boost is created equal". Since a Centrifugal designed supercharger builds boost similar to a Turbo you will see somewhat of a better fuel efficiency by as much as 7%.

I do hope that this information helps you, I do have much more knowledge don't be afraid to PM me on this forum (preferably the forum not email).

Please anyone correct me if I may be wrong on what I stated above!

If you want to go pd go roush n go through MVP tuning for the kit. Those guys know what they r doing with a roush.

Centri go with a paxton. People I know r getting great numbers and to get more boost its just a pulley swap capable of up to 1000 rwhp

Turbo systems are complicated. Grease arch Jon Lunda twin turbo kit. Direct bolt on and he will fly out and tune the first so many sold. Over a year of testing went into this kit and the longevity of the motor

This is unbiased to the point that I run a whipple. I got my kit through evolution performance if u want to take a look at them.

Hope this helps

Hellion kit was virtually bolt on with no mods needed for the Boss, doubt it's much different for a GT depending on year.

$11k out the door for install, injection, and tune for that setup I posted earlier....pricey but that's what you get for 800+ streetable HP.

Re: Twin turbo or twinscrew supercharger???

real simple from someone who's done both in the past, same car.

If you want sick maximum power and to give the car the ability to sit on jackstands most of the time figuring out what the latest thing underhood that got fried because of heat, go turbo.

You want reliable, easy-to-tune power that's always "on" go with a centri supercharger, sized sensibly, from an A/R perspective. PD is fine too, if you've got the dosh, it's probably better on the street, based on the specs but, I can't speak from personal experience on that.

The only problem with hellion is the last time I checked they only had a dyno queen for a test car. They haven't put her on the strip for actual application and other forums have posts for bad installation set ups with hellion kits. 11k is extremely high when you can get a proven tt kit that has 9 sec passes on the strip and over a year of r & d for less then 9k. Plus a proven mustang tuner giving you a great base tune to either keep or run over to ur local dyno shop to fine tune it.

www.twinturbo50.com

You will see dyno and drag videos for this kit on here

And you aren't going to get 800 hp from a stock block without turning the thing into a time bomb. I am just below my fuel pump limits at 660 rwhp. Stock Blocks can handle 700-750 fly wheel with an aftermarket fuel pump and return system.

If you really want everyday power and street able then you want a twin screw. Look at the GT500. If u want power on the hard pulls there's nothing wrong with the centri. If you want big Top End and stupid dyno numbers go turbo. A takeoff GT500 blower would be nice.

I think i will be going with a twin screw, if i want to get 700 wheel hp do i need forged pistons, my local shop said no, if they do the right tune.

Absolutely, jegs sells the roush kit for $5600, that's a full kit not tuner... Then you would need bigger injectors and fuel pump, smaller pulley, custom tune... And get rid of your cats, JLT big air kit, and with install you should still be well under 8k

Well how much is the magna sc? That should come as a mustang specific kit with all supporting items and the upgraded fuel system lines and pump will cost u roughly 1200-1500 bucks. So assuming the magna costs 5500 and Thr fuel system costs 1500, you would be paying them 2500 bucks to do the full install. I did all the work for my sc myself but that's up to u if u want to pay 2500 bucks for the install. If you have a warranty with ford you could go to the dealer and have them cancel it since they won't cover jack after you install it.

Do you already have exhaust and an upgraded clutch? These are two items you'd want to do before the sc since the clutch is not meant for over 400 ft lbs of torque.

I'm a fan of bbk, same quality as everyone else American made but not so proud of their name they cost you an arm and a leg. What you have to decide is how much ur willing to pay for someone to install it. Plus you may want to look into a new stage 2 or 3 clutch since the stock one won't hold up.

That's a lot the Paxton kit costs 3k and the new clutch should cost 600 including install. Tuning on a dyno I paid 800. So they are doubling the cost of the parts for their labor.

A full Paxton kit is over 5,475 for the polished. The tuner kit from lethal is 4,500 and change.

That's pretty high for a Paxton... Unless you're tellin me that clutch (even at an overestimate of 5k installed for Paxton) was $2800... It ain't adding up right

I was told that bbk will not hold up well when i boosted the car and was making big HP.
Is that true??

Yeah I am telling u a guy who used to be on here pretty regularly was finding them at 3-3.5k and it was the black one. I'd just ship around verify you are getting the right prove from your shop. I always buy the parts and take it to the shop so they can't cloud their prices over with inflated parts costs.

Is that true??
I am running 9 psi of boost over the last six months. It isn't true, all pipes are made from quality metal and they are torqued down just the same. I think there were problems when people first started boosting foxes so they may be referencing that era of mustangs.

So bbk has pretty much the same quality as the kooks, how is the fit?
I dont care about the brand as long as they give me the best performance.

The fit is good. The long tubes come a little lower so there is a chance of bottoming out on them but I am also lowered too and it takes step bumps to honestly catch them. The starter can be tricky to install but if ur having a shop do it then no big deal.
