BUILD YOUR CUSTOM SYSTEM

We Put This All-Inclusive System Together With All Of The Components Needed To Make 750rwhp* Using E85

To run this system at 750rwhp you must have a built/forged shortblock 

The GT450-750HP is engineered with all of the components you need to make 750rwhp safely, 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.  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 THREE TIMES better than second place. That’s not a little better, that’s lightyears better! In fact, this is the only intake manifold/intercooler available that is capable of keeping temps down far enough to guarantee that you don’t have massive power loss due to heat. Add to that our industry only integrated composite heat barrier and it gets better.

The GT450-750 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 650rwhp. The intake manifold/intercooler is the same one we use in out 1000rwhp kit (GT450-1000HP). It’s the only intake manifold/intercooler in the business that has the cooling capacity to correctly cope with more than 8lb of boost (about 400rwhp). The GT450-750HP manifold/intercooler has the cooling capacity to cope with up to 36psi of boost and 1200+rwhp.

System is complete with everything you need except a tuner and a tune. We can supply you with the tuner if you need one. Arguably the best 3v tuner on the planet has done hundreds of GT450 tunes. He can get you all set up and you never even have to go to the dyno!

What is the safe limit of my stock motor?

The safe limit of your 4.6L 3v motor is 450rwhp and 6,000rpm’s. You’re flirting with danger running any more than that. You can put this system on a stock shortblock motor. But you will need to run the blower speed so it only makes 450rwhp. This kit is intended for motors with built shortblocks. You can put this kit on a stock motor. We will have to supply you with a pulley correctly sized to make only 450rwhp though.

How much power can a GT450-750HP kit make?

The GT450-650HP will make 750rwhp reliably and consistently. Requires a forged shortblock.

How much boost can a GT450-750HP kit make?

The GT450-750HP will make 17-18psi of boost out of the box which will get you to 750rwhp.

How hard is it to install?

Installing a GT450 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 GT450 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 run the GT450-750HP kit with my cams, ported heads, headers, etc?

You sure can. Positive displacement blowers don’t care much about what motor they are bolted to. Would a “blower” cam work better than a “naturally aspirated” cam? Yeah, just a touch. Nothing you could ever feel in the seat of you pants though. As far as things like ported heads, headers, exhaust, etc. they simply make the blowers job easier. So, if you already have a bunch of bolt ons and you want to put a GT450-750HP kit on it’s no problem at all.

That said, you don’t need cams, ported heads, headers and big exhaust to get 750rwhp out of this kit. You can put this kit on a motor with good pistons and rods with everything else stock and it will make 750rwhp. You don’t even need headers.

Can I put the big aftermarket GT500 blowers on the GT450-750HP (Whipple, Kenne Bell, etc)?

You can use a Eaton 2.3L or 2.65L TVS with the GT450-750HP. The big TVS’s can be run up to about 1200rwhp on e85. If you’re looking for more blower than that you’re going “big time” anyway and should be looking at our 3V R-Spec kit. It was designed from the ground up to run huge blowers on the 4.6L 3v motors.

As far as the other big GT500 blowers go (2.8, 3.2, 3.6, 4.7L Kenne Bell’s and 2.9, 3.4, 4.0, 4.5L Whipples) the short answer is no. The big blowers will physically bolt up to the intake manifold but there will be a few issues getting it to work reliably.

First off is the drive belt situation. The 4.6L 3v motors have a 6 rib belt. All entry level blowers use that same 6 rib belt system. It’s adequate for most 3v applications but when things get turned up to “kill” the system needs to be converted to 8 rib. And even this will get you only so far. Stock GT500’s come with their own dedicated 10 rib belt for the blower and A/C compressor (they run a 6 rib belt for the other stuff). You need that 10 rib belt when playing with the big GT500 blowers. There is no easy way to convert the 4.6L 3v to a 10 rib belt to drive those big blowers. You could maybe possibly get away with running an 8 rib system on a big GT500 blower if you weren’t spinning it very hard, but it would be problematic, there would still be some fabrication necessary to make it all work and why put a big expensive GT500 blower on and not run it hard? That’s a colossal waste of money.

Second problem is that the blower offset front to rear is a little different on the GT450 so rear elbow/inlet will poke through the faux firewall a little.

Long story short is that if you’re looking at going “big time” with a 3v (over 1000rwhp) you want to be looking at a kit designed specifically for those goals. Our 3v R-Spec kit. There is a lot more to running huge blowers than “will it fit”. They need all sorts of supporting systems to work properly.

What other supporting modifications will I need?

The short answer is none. You can bolt a GT450 kit on your car and run it as is with no problems. Lots of people do this. 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 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. 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. A great tuner 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.

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 GT450 kits 50 state emission legal?

The short answer is no. It’s not because they couldn’t be made to be 50 state legal. It’s just that we don’t deal in large enough volume to be able to afford to get the kits certified. But…….

This is all in theory of course, we would never condone doing something illegal…….We aren’t in a state with emission testing so all of this is what we have head or been told. We don’t have any first hand knowledge.

There are a lot of people running GT450 kits in states with emission testing. What state you live in would determine how easy it is to get your car to pass the emission test. If your state simply tests the emissions at the tailpipe they are pretty easy to pass. Most good tuners can write you a tune to get past the sniff test. If your state has a visual inspection, it will be tougher. The good news is that the GT450 uses stock Ford parts so when you pop the hood your average person is going to think it’s stock even though they are looking at a supercharger.

You best bet when dealing with emission compliance is to get in touch with your local hot rod community and see what they’re doing. People get past emission every day in every state with aftermarket parts. The trick is figuring out what you need to do.

Can I put a GT450 kit on my 2005-2010 Mustang with an automatic transmission?”

Yes. The only difference between a manual and auto trans supercharger kit is the tune. Your tuner will be the one who “makes it for an auto”.

Why doesn’t my shop want to install a GT450 kit?

Some shops won’t want to install your GT450 kit. Not all, but some.
Your shop doesn’t want to install your GT450 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 GT450 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 GT450 kit on. There is nothing at all wrong with this. They should be doing everything they can to maximize profit and stay in business.

How many GT450 kits are out in the world?

We sold our first GT450 kit 1/7/12. There are over 500 GT450 kits out there (as of 12/19) in the world now. It has been completely tested and proven.

These are the top supporting mods/upgrades that every blower project needs to consider. And a few pretty bits. Over time a vast majority of blower cars end up with these options. These are items that do not come standard with any blower kit. With us you can get them right out of the gate and save yourself a few dollars because you won’t end up buying them twice. Once when you buy the kit, and again when you upgrade.
