The eRAM is a lightweight but powerful Electric Supercharger by eRACING of San Jose, CA. It's a 700 watt, 50 amp axial-flow compressor that puts out 3 lbs. of thrust at 750cfm. That translates to a 1 psi gain, and with two in series, net gain in pressure is about 1.5 psi. (One eRAM alone is .5psi but also relieves about .5psi of restriction, in most cases. A second eRAM adds another .5psi on to that number.)
I got together with Mark Kibort, designer of the eRAM and Super eRAM
Electric Superchargers on Tuesday, 7/29. We installed (rigged with gaffer tape)
an eRAM electric supercharger on my '94 Stealth base NT (which already was
slightly modded with K&N FIPK and resonator removed), doing before-and-after
dyno runs to determine if it does yield any real world HP gains. Well, it
works, and even with a less than optimal 'quickie' install, (blowing air at
around 40 degrees angle at the MAS honeycomb, instead of straight-on), we got a
real 5 HP in the entire range of 3000 through 5500 RPM. We had clear repeat
readings (3 runs each on the dyno at Frey Racing in Mountain View) of 170 HP
before, and 175 HP after installing the eRAM.
We met at 'The Dyno Room' at Frey Racing, which is a
company that's been around for 40 years and have respect in the racing
community. Judging from a dozen or so NASCAR types and SCCA entries in the
shop, I'd venture that these guys know what they're doing. All they do is
try to squeeze every available horsepower from the cars they work on. Our
little test on my car (with roughly 1/3 the HP of any of the other cars in
the shop) was treated with great respect by their dyno guy, a soft spoken
ex-racer named Terry Barnard (who had some interesting suggestions for
us...). He had me start at 2000rpm, then take the car through 2nd & 3rd to
4th gear and hang at 2000rpm... When he said "go", I banged it to WOT
through 5500rpm, then backed off and threw it in neutral. It really felt
like driving at 120mph (what it said on the speedo), between the engine
noise with the hood open and an humongous fan blowing cool air over the
engine (the fan was as wide as the Stealth)! -:-
