There is no way this can help your top end HP. Low end has some potential. Whether it helps enough to be worth $300 bucks???
If no one is willing to drop $300 and do an experiment, no one will really know if this will help low end responsiveness. You might want to check and see if their performance guarantee will apply for your application - if it does, then it is a risk free endeavor.
I have heard about folks buying these things to cool brake rotors on racers. The eRam company has been around for at least 5 years, and while they typically make more sense on lower HP applications, you guys might be onto something.
I hope someone steps up to experiement - it would be interesting to see what happens, or doesn't happen.
Good luck, all!

All innovative people throughout history in aviation, engineering, medicine, science etc have been laughed at and been the butt of jokes but they have continued in their pursuit of knowledge. I pray that if any of you ever get an idea that you are passionate about that you find someone that will encourage you instead of laughing in your face. That being said, I am putting my wife's salad shooter inline with my turbo!!!

Who's and which cheek? Just having fun with you. I think Stephen has a good idea and hope Mike will allow him to test the eRAM on his dyno and publish the results here. I don't know Mike but it would really help his cause to let Stephen test it.
Damn! My x-ray glasses just failed!

Guys don't get your hope up on this thing.
There is a huge difference between bolting a hair dryer on the intake of a high compression NA civic and a 930. If there was any benefit to our cars from this you would have seen them on the Porsche race cars long ago. Or maybe even on NA street cars. Companies spend big bucks to get 10hp from an engine (varioram, variocam for instance) imagine forgoing all that and just bolting a fan on your aircleaner. The engineering and manufacturing savings would be huge.
Now as a brake cooling system it might be pretty cool.

Like i mentioned, i wonder if it will decrease lag, or to what extent.
by the way, what is the baseline hp you expect on the car to be modified?
If the hp to the wheels is over 250, you may be in excess of the pressure generating capabilities of the eRAM at that those mass flow rates. however, if there is restriction in the air box, it could work fine.

So that pretty much eliminates all Porsches except early 911's and 914's. Back to bolting it on 4 cylinder Hondas.

You may not understand the potential of such a device. Ive demonstrated the eRAM in front of crowds of people at a dyno and seen the positive results.. actually, for reasons you may or may not understand, the gains are mostly at the top of the HP curve at the higher rpms! my 240hp 928 engine got 10hp to the wheels with the eRAM on and then removed and off the car's engine.
the several 911s with 195 or 200 rear wheel hp , stock, got 10 hp to the ground with the eRAM just attached to the intake of the stock air box, using a KN filter.
we are not talking about a hair dryer. 850watts, 60 amps, 27,000rpm, 3lbs of thrust out of the eRAM is really nothing like most have seen before. AND the proof is really in the air box or air intake tube when we get an accurate pressure reading from a very accurate pressure sensor and it shows, vacuum of about .5-.7 psi, and with the eRAM on at WOT and at REDLINE, the vacuume drops and moves to a slight pressure. remeber, we are only talking about 1psi net change in the intake, but thats 6% or so, and on a 200hp rear wheel hp car, turbo or NA, thats about 10hp.
I think with this group, we are talking about turbo lag, and you may see gains in the bottom end due to faster spool up. i dont know. ill have to look at the 200 rear wheel hp dyno runs we did 10 years ago on a MR2turbo , just to see if the turbo spooled up quicker (set at 17psi boost on the turbo, not absolute, so the gains were 10hp on top of the 17psi of the turbo setting)
