From the description I would say it was engaged mid run.
Of course if multiple runs were made with/without it installed the same day that would be a better test.

This is what would take place between a DOHC 2.5RS vs a SOHC 2.5RS. One has a better low end (SOHC) and one has a better top end (DOHC). They both get to the 1/4 mile mark at the same time, however the DOHC would have a slightly higher trap speed. In the end, it would pass the SOHC 2.5RS had they raced further. Ok...that's ONE example. I tire of typing!

I was speaking of a model airplane engine. the E-ram may have helped him with his trap speed simply because the svx breathes deep. In low end there is more than enough flow to keep the engine satisied. Once it starts flowing more(higher rpm) the intake may become a little more restrictive(this is where the fan may help) this will bump his trap speed up but to be honest I feel it mainly effected HP rather than torque since the torque is more relative to ET like trap speed is relative to a power/weight ratio. So torque curves remaining relatively the same the time will be relatively the same but when HP is bumped, the trap speed gets bumped....Hope it wasn't too cunfusing for ya cuz it is still confusing me

Those Starter motor powered turbines look neat. Can't say I'd install one of those either though. What guarantee do we have that the injectors will be able to provide enough fuel even w/ it blowing into the MAF. I'd rather run stock than lean. The SVX (USDM) runs frighteningly lean as it is. I like having piece of mind that lean detonation is not on my engine's transcript.
Just my $.02 |

Now, if the motor speed responds to RPM then this would make sense. However, my understanding is that you basically have a small electric motor constantly blowing the same rate into the intake. If this is the case, then how would the engine benifit at high RPM while being starved / restricted at lower RPM? If the motor can meet the demands at high RPM why does it cause restrictoin at lower RPM? It just doesn't make sense to me. I'm guessing that if the e ram is spinning at the same rate at all times then it may have to do w/ intake vaccum but that's just a guess. I'm trying to think of variables in the intake system and VAC is one of them. I honestly don't know though and that's why I'm asking. Well, now that I racked my brain over this concept, I suppose if it was turned off at low RPM then forcing the air to move around the inactive fan blades would cause restriction. Thoughts anyone? What were the connections involved when connecting the e ram? Last edited by SEA Sleeper; 05-27-2005 at 12:47 PM. |

I think that $300 for .3 seconds is'nt worth the dough Better off buying a tornado fuel saver(buy it now Ebay price $35.99) .I had a Tornado i my GMC V6 Sonoma and it made quite a difference!!! I'll bet the Tornado can give .3 tenths ,For $36 bucks MUCH BETTER DEAL I think i'll get one for my Subie FYI: The Tornado Model for our svx's is KI-75!! THAT'S MY 2 CENTS

He said he also gained 5mph in his trap speed. 5mph!!! Powered, if you happen to get your hands on another one of these, PM me. I'd like to do some dyno runs with and without it.

Sorry it took long to return,my increased trapspeed was do to worn tires and massive wheelspin.I think the e-ram works somewhat by cramming more air into the engine at low rpm and giving you a ramair effect at high rpm.I purchase new tires and my car still pull a 14.92 at 94mh,without the eram.I'm sure it will pull a 14.7 after I install an inline pump with the later to be purchased eram.Well people will always doubt something will work but with the stage one software it will be a fairly strong setup without nos.Also the inline pump will be for something else a little further down the road.

I get the impression that he was saying that by the time he got to install the e-ram, traction had become worse, but he was able to maintain consistent 1/4 mile times because his trap speeds were improved by the e-ram. So, the e-ram provides a HP improvement out to at least part of the 4000-6500 rpm range utilized by the 4eat during full throttle runs.

With my new tires my 60 ft dropped from 2.2 to 2.16 but my trap was still around 94mph,I was saying that with my worn tires and the added power of the eram that caused the increase in trap speed,hell I have ran a 14.5 at 110 on nos second gear wheelspin is a blast.
