Thread: Venom Coolers (intercool your snout)

I am not sure if this is in the right spot or not but i am trying to see the interest in the 3800 community of venom coolers. A venom cooler is like a inter cooler for your blower snout it can either be tied into your stock cooling system or your after market inter cooling system.

Here is a photo:


and a short video about the cooler:

I am excited for the release of the stand alone unit and the blower swap

I can imagine. Might even make a snout flush easier. Or maybe add an external filter.

What type of temp drops are expected here? I'm assuming this is for the oil in the snout?

temp drops appear to be in about the 100 degree range from what I was just told, but that also depends on the pulley size if you are tapping into you stock coolant lines or tapping into your I/C lines, here soon we will have stand alone units tho which will be the cooler with its own pump and little rad. to mount in the front of your car.

It does not go into the oil of the snout water jackets are made to cycle water around the snout and back out

I'm interested in this to see how well they do.

And what would be the price in this?

pricing right now just for the front-drive (snout) is $450 but the more that are wanting to buy the cheap it gets so if enough people are interested in getting one we can arrange a group buy for you guys. I will be bringing in a Gen 3 front drive later this week and we will be making one for "alkygto" and we will be sure to post some photo's of that.

In the price of $450 you get the liquid cooled snout, 3 feet of line and the fittings. We will be working on a stand alone system but do not have the pricing for that just yet.

here is a video that shows the temp of a blower

574 RWHP with Venom Cooler and ported blower - YouTube

if you want to skip to 5:39 that is when we take the temp reading of the blower

In the videos they claim that the Eatons suffer from bearing failure due to heat. I've seen plenty 200,000+ mile gen 3 blowers still running fine.

the snout is where all the heat of the blower comes from, by cooling the snout itself you help lower the temp of the blower itself in turn helping to lower your intake temps even more. Also even if you are running a phenolic you are still going to get heat transfer from the motor to the blower (not as much but it is still there) by keeping the whole blower cooler you eliminate heat soak which will take hp from you, and with a hotter blower you are going to be breaking down the oil and putting more stress on the bearings in the snout.

what size pullies where these 200,xxx miled blowers running? i run a 2.7 and I am pretty sure that mine will not last 200,xxx miles

Whhhhhhhhhhhhhhhhat!?!?! Most of the heat, in a supercharger, comes from the snout!? This statement alone makes no sense. Most people understand that two large rotors spinning at high speeds within .001 mm of each other is where most of the heat comes from. Yea, the snout does generate SOME heat, but not nearly as much as the rotors themselves.

And looking at our roots blower..........the snout isn't even CONNECTED to the LIM................so any heat produced at the snout has to go through the case of the blower to get to the LIM, etc, etc....heatsoak. Why try to put a fire out with a water bottle, when I can put it out with a bucket of water?

Your logic is way off dude. The heat from the supercharger has nothing to do with "the rotors spinning 1mm from each other". I mean "really"? Heat in a supercharger comes from compressing the air (in a supercharger it's called "adiabatic efficiancy"), heat transfer from the engines combustion, and from the friction in the front gear drive. That transfers to the rest of the case which is why we typically see higher temps by the front drive than at the TB side of the case. Again, a lot of conjecture here without looking at what is actually happening or even understanding how things work. And yet people pass themselves off as "experts" lol.

Has anyone watched the videos on Youtube? I think they explain how it works and show the temp differences. And that car is equipped with a "killer chiller" which was'nt even in use for the vid. When the KC was used in conjuction with the VC on the SC equipped with a SB the case was actually COLD to the touch after some spirited driving.

I will say it again. WHO CARES how cold the case is....The air coming out of it is the main thing.

If you don't have a IAT in your LIM then this thread is on it's way to epic fail.


What has failed to have been explained so far is:

How does cooling the snout cool the charge coming out of the blower?

A root style Eaton blower doesn't compress air nearly as much as a twin screw blower................so for you to tell me I don't even know what I'm talking about, and then say something like that, is complete hypocrisy.

But you're right, most of the heat that is generated is from the "compressing of air" and the two rotors spinning (exactly what I already said)........... So how is cooling a supercharger snout.........a piece that is totally isolated from the rotors, something that is going to increase efficiency??? You typically see higher temperatures by the snout because it is at the opposite end of the air intake..........therefore isn't being introduced to fresh, cooler air like the TB side of the blower. Yea, some heat is definitely generated by the snout, but not nearly enough to say a snout cooler is necessary. Many of us running full core intercoolers have superchargers that are "cool to the touch" after spirited driving.

You shouldn't throw statements like " adiabatic efficiency" around if you don't know how to spell them..........or how it relates to the M90 roots supercharger we have on our platform. You see, adiabatic efficiency correlates directly with how much work a compressor has to do to compress air to a specific point. Only problem with your logic is the M90 roots supercharger does NOT do that much compressing!! Unlike a twin screw supercharger or a centrifugal supercharger, the amount of compression that is generated is minimal. Actually, the roots style blower is by far the least efficient type available. Cooling the snout will not increase efficiency of the blower..............

So, Why do I need a snout cooler? Some people make the point that cooling that area will increase the efficiency of the bearings and coupler, therefore increasing their life span......I've only heard of a handful of snout bearing failures because of fatigue (a lot of bearing failure is because of improper pulley installation / removal), and I've NEVER heard of a supercharger coupler failure because of high heat and fatigue............

Most were on stock pullies. In that respect how many members are actually running a 2.7" pulley that haven't gone turbo yet?
