We Put This All-Inclusive System Together With All Of The Components Needed To Make 750rwhp* On e85
The GT550-S550-750HP is engineered with all of the components you need to make 750rwhp safely, consistently, reliably and without any shortcomings. We have taken the guess work out of figuring out what you do and do not need. Every component has been chosen and matched to reach 750rwhp. No one else offers kits that are this inclusive. All other kits require a laundry list of parts after the purchase of the blower to reach 750rwhp and make consistent power. If they can even get there.
The system is built around our industry leading billet intake manifold and intercooler. The manifold/intercooler is the foundation of any positive displacement supercharger system. Not the supercharger. It doesn’t matter what supercharger a car has if the intake manifold/intercooler are not up to the job. With most supercharger systems you can upgrade the supercharger. But, you can’t upgrade the intake manifold/intercooler. In most cases the intake manifold/intercooler you start with, is the one you’re stuck with…. forever. Our intake manifold/intercooler has the capacity to cool the intake air charge over 60% better than second place (two way tie between Whipple Gen 5 and VMP Odin) and 300% better than third place on back. That’s not a little better, that’s a whole lot better. Add to that our industry only integrated composite heat barrier and it gets better. Nothing can control intake air temps like the GT550.
The GT550-S550-750HP comes with a integrated composite heat barrier. It is not an add on, it is part of the manifold. The composite heat barrier greatly reduces the amount of heat that travels from the cylinder heads into the intake manifold and therefore the air inside of it….which you want as cool as possible. The composite heat barrier is a complete game changer for positive displacement blowers. The entire intercooler system works better with it in play.
No other supercharger system is engineered to make 750rwhp. The intake manifold/intercooler is the same one we use in out 1000rwhp kit (GT550-S550-1000HP). The GT550-S550-750HP manifold/intercooler has the cooling capacity to cope with up to 36psi of boost and 1800+rwhp.
Our tensioner system is the only one we know of with enough travel and spring pressure to handle the job. The correct amount of travel is PARAMOUNT when designing a tensioner system. If you have enough travel you can ensure that the tensioner never hits its hard stop. That is what breaks oil pump gears and cam drive sprockets. They have also been known to break crank snouts. As far as we know not one single GT550 customer has broken their OEM oil pump gears or cam drive sprocket. That’s not a guarantee they won’t. But history is on the side of them not breaking. Our tensioner design also has enough spring pressure for the job. No need for added idlers for more belt wrap, trick blower pulley coatings, etc. All you have to do is set the tensioner to spec (as far as we know we’re the only company that provides setup specs) and forget about it.
System is complete with everything you need except a tuner and a tune. We can supply you with the tuner if you need one.

What is the safe limit of my stock motor?
The safe limit of your GenI Coyote motor is 750rwhp and 7,250rpm’s. You’re flirting with danger running any more than that. You can run this kit at the safe 750rwhp and 7,250rpm’s until your motor is forged.
How much boost can a GT550-S197-750HP kit make?
The GT550-S550-750HP will make 11-12psi of boost out of the box which will get you 750rwhp*. The blower will make a lot more boost than that. But you will run out of fuel injector after 750rwhp on e85. You will need bigger injectors to run more boost.

How hard is it to install?
Installing a GT550 kit is no harder to do than any other positive displacement blower kit. And easier than some. There is a little more “hot rodding” when installing a GT550 kit but nothing that is mentally challenging. Just a little more time consuming. That’s splitting hairs though. The instructions (which can be found on this site) are very thorough and everything is explained in detail. Installing blower kits is not “hard”. They’re time consuming because there is a lot to do. But they are not “my brain hurts” hard. Most people are capable of doing a blower install for their first big project.
It will take your average home mechanic 16-18hrs to install. Basically, a weekend. If you’ve done blower kits before or are a little more advanced it takes about 10-12hrs. If you’re a “Pro” expect it to take you 9-10hrs.
Can I still use my OEM strut tower brace?
Sorry, no.
Can I run the GT550 kit with my cams, ported heads, headers, etc?”
You sure can.
Can I put the big aftermarket GT500 blowers on the GT550 (Whipple, Kenne Bell, etc)?
With the correct adapter plate, yes.
What other supporting modifications will I need?
To make 750rwhp you will need BIG exhaust. 1 7/8” headers into 3” all the way back preferably. We can supply you with the exhaust. That takes care of “needs”. Of course, “need” and “want” are two complexly different things. Supporting mods that you “want” are pretty much endless. The kits have a lot of these as options. And we can supply anything else your heart desires. Our sister business Department Of Parts carries nearly everything.
Who can tune my GT550 kit?
Any tuner that can tune a Mustang can tune a GT550 kit. Most tuners will find that the GT550 kits are easier to tune than some others because it uses stock Ford parts for all of the tuning related items (injectors, mass air sensor, intake air temp sensor, etc)
You can get your car tuned at your local dyno facility or you can have it remote tuned. The simple explanation of remote tuning is that you do driving tests for the tuner. You then email them your logs (the data your tuning device sees), they make changes, then email you back an updated tune. You repeat this process a few times until your car is tuned properly. Remote tuning works very well and 9 times out of 10 it is what we do ourselves.
Why doesn’t Department Of Boost supply tunes with their kits?
To be perfectly honest the number one reason is it’s a PITA and tuning is not what we do. If we wanted to offer tunes there would be a infrastructure put in place to support that and we simply aren’t big enough to add a “department” for tuning.
Additionally, we are not fans of supplied or “canned” tunes for blown cars. Even if we purchased a blower kit from another company we wouldn’t run the supplied tune. Supplied tunes are very, very safe. And that means they are down on power and run very soft. Supplied tunes need to be that way because every car is a little different. If they were to supply a dialed in tune it’s possible that someone will put it in a car with some other mods other than the blower and it will not be safe anymore. Canned tunes are pig rich and don’t have much timing. They run like crap.
You really, really want a custom tune for your car. The number one reason is so you can be 100% sure you are tuned safe. The number two reason is you want your car to make all the power it can make and run well. Tuning is incredibly easy in this day and age. There are dyno shops on every corner and if you don’t want to do that there are a couple of tuners that do remote tuning which is a great option.
Are the GT550 kits 50 state emission legal?
No
Why doesn’t my shop want to install a GT550 kit?
Some shops won’t want to install your GT550 kit. Not all, but some.
Your shop doesn’t want to install your GT550 kit because of one simple reason, money. We are not saying that they’re wrong for basing it on money. Making money is what they’re supposed to be doing after all.
When your shop puts a blower on your car they are usually selling you that blower, which they make money on. They make money because they are set up with one or a few blower manufacturers (or distributors) and they get their kits at a lower price than you do. We have already priced our kits as low as they can go and that is the price we give our customers. We didn’t pad the price so we can afford to sell the kits to shops for less than we do our customers.
Most shops bill by the hour ($100/hr for example). And they pay their employees by the billed hour. If the shop charges you 12hrs to put a blower on and it takes them 14hrs they “lost money”. And the employee isn’t going to be too happy because they just got paid for 12hrs but it took them 14. If a shop sticks with one or two different blower kits and only installs those they can get really fast at them and make more money. They will still charge for 12hrs, but if they can do the job in 8hrs because they have done so many of them they are very happy. There is nothing wrong with this at all, it’s smart. But if they’re only installing a certain kit and doing it faster than 12hrs every time they are going to be less thrilled about tackling a different kit and maybe seeing their work time balloon to 12hrs+. It’s not that your shop doesn’t want to install a GT550 kit. They just don’t want to install a different kit then they’re used to.
Your shop makes money when they sell you the blower and they can make more money per hour if they get fast at a certain kit(s). That is why some shops won’t want to put your GT550 kit on. There is nothing at all wrong with this. They should be doing everything they can to maximize profit and stay in business.
Can I put a blower on my high mileage car?
Yes you can. But it depends on what shape the motor is in. And that mostly boils down to cylinder sealing. If you’re at all concerned about running a blower on a high mileage do a compression test. And if you’re really worried do a leakdown test. If the numbers are good you can put a blower on.
How many GT550 kits are out in the world?
We sold our first GT550 kit 10/2015. There are over 250 GT550 kits out there (as of 12/2019) in the world now. It has been completely tested and proven.

“Who can tune my GT450 kit?”
Any tuner that can tune a Mustang can tune a GT450 kit. Most tuners will find that the GT450 kits are easier to tune than some others because it uses stock Ford parts for all of the tuning related items (injectors, mass air sensor, intake air temp sensor, etc)
You can get your car tuned at your local dyno facility or you can have it remote tuned. The simple explanation of remote tuning is that you do driving tests for the tuner.

Remote tuning works very well and 9 times out of 10 it is what we do ourselves. Arguably the best tuner in the world for the 3v is Manuel Pazo from Tudyno. He is who we use for 3v tuning. He can be contacted at manual@tudyno.com. You can also find him on Facebook.
