Good for about 8 WHP E-Ram (electric supercharger)

[d_m_kolb]

Please do not light me up for talking about this product before reading the whole post. A friend of mine bought a E-Ram. It's a electric super charger. I didn't figure it was going to do anything but he wanted to try it so he did. This is what he found.quote:Alright, tried the E-RAM this weekend. I didnt bring it to the dyno, I did about 10 G-TECH runs with and without it on the same stretch of road.The E-RAM should be mounted behind the MAF on MAF cars as it WILL screw up the reading significantly.On the MAP based accent GSi, the MAP sensor reads a +.9 psi at idle and a +.3 psi at WOT (6000 RPM). It gives about 4-5 WHP on the accent and I read as high as 12 WHP on the Tiburon. However consistently I was reading 8 WHP, 138 to the wheels with it and 130 WHP without the E-RAM (with 2900 lbs wieght entered). Keep in mind that my tiburon has a full breather system (I/H/E). The accent just had the CAI.I couldnt feel the E-RAM power up when I turned it on, however at high RPM the car did not lose power as it normally would, the power stayed strong until redline (6500 RPM).The E-RAM draws only about 30 AMPs when working at WOT, but at idle if turned on, it could blow the fuse, as its working harder drawing the whole 50. Also the inline fuse provided with the E-RAM is crap, the fuseholder burnt out on the first run. Not the fuse, the fuse holder. Couldnt figured it out, there was conductivty through the fuse holder, but the internal resistance had climbed so high that it would only let about 1 amp though.... So it got cutout, .Also the current that the E-RAM draws comes entirely from your alternator, not your battery like the site claims. Your alternator is CHARGING your battery at around 14.3 V. Your battery with the car off is at most 13.0 V. With the E-RAM on the system voltage with the car running, dropped to about 13.9-14.0, meaning that no power was being drawn from the battery, also you could feel the alternator working harder when you powered it up. (As if the dim interior lights didnt give it away).I had the E-RAM blow off the CAI twice, and the results were not consistent, but it did provide the gains it claimed.For now, the E-RAM is being mounted on the accent GSi.We figured out the reason it blew off the TB a couple times was because the TB was closing before the E-Ram shut off. Were working on that and will keep you posted. The E-Ram comes with a switch so that it only comes on at WOT.The E-Ram does what it claims. I'm making no money for saying this I have seen the prove. Is it worth $300 for 8 to 10 WHP, maybe that's a pretty good gain really. Here is the E-Ram website http://www.electricsupercharger.com

Ok here is a up date to this post. A friend of mine has bought the E-Ram and dynoed it on his Hyundai Tiburon 1.8L engine and his Hyundai Accent 1.5L engine.He was getting 5 to 7 WHP for the Accent and around 10 to 11 WHP for the Tib. Thats pretty good. Your probably losing around 25 to 30% HP lose through your trany so the actual crankshaft HP might be around 9 to 10 HP for the Accent and 14 or 15 for the Tib. Is it worth paying $300 for the E-Ram to get around 10WHP? That's up to the buyer, and what you will be doing with the vehicle. I think I'm going to get one in a few months. My buddy said you could really feel the car pull hard at WOT when the E-Ram came on.

Reread the post. The second post is not dynoed with a G-tech. It's actually dynoed with a machine at a garage. The numbers in my second post are the numbers he got when sitting on the dyno all trapped in. Also he ran the car with the E-Ram in place but where it didn't turn on. It didn't hurt performance just having it sit in the CAI. It still increased WHP by 1. So that means even when your not at WOT it actually help HP and then really helps HP when it turns on at WOT.

Well, the GTECH is not exactly right but it is usually around 1-4 off in the HP range, around .5 off in 1/4 mile times and 2-3 mph off in the 1/4 mile run. They are actually pretty good measures if you don't have the time to actually do the real tests.

I realize this and his normally HP increase was around 12 HP so I took off 4 HP and that leaves you with 8. Still a good mod for $300.
