Does or has anyone played around with one or two of these ? Wondering if they are worth the $$$$ ??? New pipe and a couple of these should be worth around 60 HP.....

You can by the higher CFM models at Home Depot for much cheaper. You can even get them in a gas powered version if you don't want to put the electrical load on the system.

Coolest thing since ShamWOW! Works about as well too.

not 60hp, but we did see about 7-8hp on a 240rwhp 928 '84. With the holbert machine in the 320rwhp range, we saw a near 5hp gain but the main gain was a flattening of the Hp peak. (much broader)

they are designed for 200rwhp type cars and less, or you can put one on each intake tube. (kind of expensive for the gains) Generally designed for the porsche 3.2 liter AFM type set up and 10hp gains were found there . Otherwise, they are really for the Hondas as a perfect adder to the intake pipe most employ.

Let me know if you need specifics.

Also, they are working on a DC brushless version right now. (going to the dyno this month) that runs a 2000watt version on two oddessy batteries (separate) . about 2psi on a 5 liter engine. Called the "Ultra"

HEY!!!!


Oh wait you said ShamWOW, not SharkWOW..




Concept is sound for small increases on NA cars. The dual intake design makes it a challenge on our cars. Running in parallel will give you more flow but not nessessarily the ability to run a higher pressure. Most of the stuff on ebay and at HD is junk and not capable of providing even a 1psi boost.

Mark's stuff looks good on paper. There is a much more powerful version coming out for 5.0L engines, but again our dual intake will pose an issue.

The concept is very sound, use stored energy in the battery to drive an electric "Supercharger". The issue is having a big enough unit to truly raise PSI and then to provide it with enough power to run with out having a parasitic drain on the engine cancelling out the effect. Or having to have a bank of heavy batteries, again cancelling the effect of extra HP. The new E-ram should have a seperate 24V battery and charging link so for short WOT burst it will indeed provide some boost. Still were talking 1-1.5PSI boost verse a SC at 9 to 20PSI and a Turbo at 15-32PSI. But an extra 7-10HP for $500+/- is on par with headers both in benefit and price. For the guy who doesn't have $7-9K for a real boost set up it could still be worth it.

Flame me now, but I do plan on beta testing the new E-ram as soon as it's ready. I'll be running a pair in parallel. My airbox is already epoxied **** and sealed. So they go right behind my cone filters.

"The new e-RAM-HHP-24V is roughly 3.5X the power of a single e-RAM (e-RAM 833 WATTS, e-RAM-HHP 2800 watts), which allows the HHP to generate roughly 2.5X the air-flow over a standard e-RAM, creating the same 5% HP gain on larger, higher horsepower engines as is normally seen from our standard unit when mounted on smaller, lower horsepower engines."



One of the issues with only providing 5-7 extra HP is dyno runs can vary that much run to run on the same day.

So there are no bunch of flat fans one can put on top of the air filter and sealed to the raised upper air filter box roof?

Nor is there room to jam a slim fan between the air filter and the MAF?
Not sure how the MAF is going to meter the air coming right off a fan.

Is mine an E-Ram supercharger or Eaton M112? I think an Eaton.

flat fans cant do the trick. centrifugal electric fans, dont have the flow, axial flow fans, need to have a lot of power to make pressure at these air flow rates of a 4.7 or 5 liter engine.

It takes power to make power. the equations are pretty simple. you can get about 1psi for near 1000watts of mechaical energy. (near 1500watts of electrical energy in) there is efficiency of the motor, and the fan itself.

we did do EXTENSIVE tests with the air box, measuring ram air under idle, but 100mph, then WOT, etc. interestingly, the stock air box creates .25psi of vacuum. AND when you seal the stock air box. *(as it leaks naturally at the air filter seal) you raise the vacuum to near .5psi. The eRAM can neutralize the vacuum and provide slight pressure. Again, we had repeated results with the .3.2 liter porsche 911 of 10hp on top of 200 rwhp. on the 928, it was a bit less. more like 7hp on top of 235rwhp.

the trick is the dual intake and making pressure for a larger engine like a 5 liter. thats where the new Ultra version comes in . with a much higher rpm fan producing near 3psi static pressure and something in the 1.5 to 2psi range at 500cfm, it should provide some good gains. Its not rocket science here. If we produce 1.5psi, the gains will be near 10% hp increases.

There is no other way to do it, except with an electrically driven centrifugal blower, but then, it needs to run all the time as it is in the air flow tract. one of the nice things about an axial flow design, is that it has very little restriction for part throttle operation and can be used with a binary control (on or off) to use its potential. yes, axial flow fans can make pressure . they were used in early passenger aircraft for pressurizing the cabins at high altitudes.

Hope that clears some things up.

ShanWow actually works, I own four of them! (actually I have the knock off brand, still works great!)

Okay thats quite enough! Its all about Zorbees!!!!

Hoops88S4

Original Zorbees!!

danglerb

What sort of heat rise do you get from a pair of those 1000 watt hair driers?

mark kibort

pv nrt (use .5psi and see what you get)

Its minimal and not a significant factor.
