Preparation for the STILLEN supercharger

Kyle@STILLEN

I don't know to be honest...I know that we run them on our GT R rally car and they work really well. If you find some of the video's of our GT R rally car on Streetfire you'll hear them. I would look for them myself but my computer at work doesn't have speakers so I won't be able to hear it.

So my dealer told me to be super careful and not to hit any puddles to avoid risking hydrolocking...I can't say I haven't hit a puddle or two but no issues... Should I be as concerned as they made it sound I should?

sorry I'm great at goin OT.

A puddle large enough to hydrolock your G3's would be 3 ft deep. Dont worry about it.

If you hit a puddle large enough to submerge your G3's...I hope you're also wearing a snorkle!!!

Seriously though, no you'll be fine. Your dealer is just being extra careful, which is good. The G3's are mounted very high, you won't have to worry about that.

StillenZ

cool.. I didn't think it was the problem that they were making it out to be... thanks for the answer... can't wait to hear some news at the end of this week!!! I might just drive my *** out to Cali to talk to your "guy" that's holding this thing up if I don't hear something soon! lol

god hydrolocking is never the problem anyone makes it out to be. Experiment for you take an air filter ram it into a sink the next time you wash it with the coupler side up and see how much water gets in. I used to run a cone filter outside of my car (like above the hood) because well the whole supercharger sat above the hood and i drove it on days that seemed like the big man himself was pissing on my car and never had any problems because by the time the water makes it through your filter it mixes with air and becomes a fine mist that just burns right through. I could see a problem if you drove into a lake tho like that Bugatti in the videos.

Edit: and damn right the sliders don't work i wish they did but then i just wander on over to the NSFW thread

Stillen, what HP level did your engineers design the intercooler for? GTM's is up to 700 hp.

I'm just trying to get an idea for future expansion, if needed.

Hydrolocking can be a huge problem if the filters are too low. Take for example the Nissan 300ZX engines. We used to have those things come in reliably every winter because all of the cold air intakes mounted the filters directly in front of the radiator just a few inches above the bottom of the car. It never failed, every winter for about ten years we would have about 4 or 5 cars in our shop getting rebuilt motors due to hydrolocking.

I've also seen a few G's and Z's with hydrolocked motors due to the intakes being mounted really low. It should absolutely be a concern. If it wasn't a concern then companies like AEM wouldn't worry about including their by-pass valves in their intakes.

With that being said though, you have to submerge the filters in order for the water to be sucked up through the intake. You have to look at the engine like a big air pump, that engine starts sucking in air pretty hard when running and even harder when boosted. It can absolutely suck up water and damage the engine.

Kyle@STILLEN

It's kind of hard to answer that question.

An air to air intercooler can pretty easily be rated to a certain amount of horsepower because you can measure the volume of air traveling through it efficiently.

However, with an air to water intercooler setup there are a few other things to consider. In the packaged standard form that the kit comes to you with no modifications, you can expect to support around 600 horsepower or so. However, if you decided to modify the system with a few minor little changes, you can support even more. An old trick used by many drag racers is to pack the coolant reservoir with ice. Obviously this chills off the water even further thus improving the efficiency even more.

Another option is to upgrade to a larger heat exchanger so that you can cool off the coolant longer thus lowering the temperatures further.

Because there are so many different things that can be done with an air to water intercooler we can't really put a blanket number on how much horsepower the intercooler can support efficiently.

What I can say is that we are using a heat exchanger which is larger than the heat exchanger that Magnusson supercharger's uses on their kit for the Corvette's.

How much horsepower do you want and what do you plan on doing with the car? Is this going to be street only? Road Course car? Drag racer? Dyno queen?

My car will be used on the street only, do you have a S/C kit if I want about 450whp? Nothing too crazy, just a complete turn-key kit.

Kyle@STILLEN

As much as I want to answer this question I'm having to keep my mouth shut. Until we're ready to release more information and have dyno's to support our claims I can't definitively answer any questions regarding levels of horsepower.

Kyle, I want at least 400 whp. Are you going to give me at least 400 whp?

Kyle, thanks for the reply. The exact power goals are not yet known, but I would definitely consider pushing 550-575 on a built block.

I am aware of the ice trick as many Mustang drag cars used it. I dont plan on using that method as I am a road course kind of guy. I would like something a little more permanent. If you guys have a bigger radiator available, or know a place where I can get one, that would definitely be something I'm interested in. I'm sure a higher rate coolant pump would be needed, but its all still hard to tell until you guys release more information about the kit's components.

When it comes to boost, I would prefer to overbuild.

That's fair, but when you can start giving info, I'll need you to suggest which route I should take to achieve a safe power level on the stock block.

StillenZ

Kyle, if you wanna PM me I promise that I won't tell a soul... It'll just be our secret! This is the first time I have felt the need to contradict anything that M4A1 has said but I'm gonna be needing 450-500 Unicorns! lol lol lol (sorry prolly not that funny to some, but a few will understand)

I will also send you one of the best frozen pizza's that you have ever had in your life not playin, you name the toppings lol... A little bribery never hurt anyone right?
