We tried it with a 300(something)cc golf cart engine a few years ago, nothing at all...

 

Well i'm not comparing it to a turbo or supercharger... you need to take a deep breath. This is obviously bothering you... I'm looking for someone who can explain what would be required of the fan to allow for a power gain of some kind.... Saying it's a crappy *** fan doesn't validate anything.... showing me what type of vol. is required on behalf of the fan to make this work would.

For those who say an N/A engine is not effiected by the forcing of air that is not done by pressurizing the air, then why the ram air system? Why are their proven gains from free mods and expensive pieces of ducting from SLP (ram air)?

 

this is more of what I was looking for... was it one of this ones you buy or did you hook a vaccum up too it?

 

Just an electric high speed fan with a sealed tube...

 

Somebody show me a currently mass produced electric motor that can power a fan 3" in diameter at a high enough RPM and with enough strength to flow 700+ cubic feet per minute of air at velocities exceeding 300 feet per second... and that weighs less than 1000 pounds...

What's that? You can't? Oh... didn't think so...

 

The ability to DRAW cool, dense air into the intake is what sells these items. They DO NOT FORCE air into the engine.

 

I'll make it simple the tuner at www.revxtreme.com Jeremy formato tested it on an ls1. We got a loss of 5hp to the wheels by adding it. Took it back out and 5hp reappeared. End of story!

Thanks!

 

97blkz thank you


End thread!!!!!!!

thats all I readlly wanted if you read my first couple post... then it seemed impossible to find...so i started probing.... I wasn't the first curious to see if they worked...

 

so wait. we all told you EXACTLY what would happen and that wasn't good enough? Do you think that we just pulled the theory that it wouldn't work out of the air? There are reasons why it will not work and we covered all of them,.

 

Because it's a restriction simple to the point. The amount of air it moves through the closed system is less then the amount of air flowing without it. The engine is a suction device, put anything in front of it and it will be a restriction. You put a K&N on it provides less restriction. You add an electric motor you've created restriction. Now the vacuum has become greater between the engine and motor, but less between the motor and air filter. Simply put the electric motor cannot provide enough CFM that the motor can do on it's own. Case in point, my current motor w/ a 91.5 mm turbo at 24lbs of boost makes more power(1248 RWHP) then my old motor at 30lbs w/ a 106 mm(1238 RWHP). Reason being that the heads flow better and can make more power with less boost, less restriction. And that's coming from the baddest **** LT1 out there.

 

Do you have that green one, with a front clip conversion???


Im not trying to be diff. I just want some clear answers, not it's dumb and wont' work....

Seeing as it's been test on an LS1 and produced a loss I will accept that it's a full restriction.

Now for a question that moves into this Ram Air? Is this air just cooler and therefore more dense or does it this reduce the restriction on of air to the T/b?

and just one last thing. Does anyone know what a Stock LT1 or Ls1 inhales (CFM's) at idel and at WOT? This is the mathmatical answer...

 

colder dense air is all you get. Ram air is a name used by GM. it is not a fucntional part. you get the same performance from any CAI

 

I know actual ram air doesn't kick in until like 200mph... i was just curious if ti was "flowing" air into the induction system there by reducing restrictions.....

 

are u serious?? lol, u think i'm bothered by a person who can't read all the answers already posted?? it's the interweb.......

 

A stock displacement LS1 at full throttle at 6200 RPM will consume ~500 CFM. This is assuming 70* ambient air temp and an engine VE of 80%.

At an 800 RPM idle it will take in ~50 or 60 CFM.

 

not trying to diff. again just asking if this is correct.... If you had a fan that propelled more than 500 CFM would it still be a restriction????


yeah my flame suit is still on.... this is a serious question i'm just trying to understand these princples....

 

I can probably find a fan for my living room that moves more than 500 CFM of air. The issue is the fan's motor being strong enough to propel that VOLUME through a 3"-4" tube. There is a reason a turbocharger's 3" exducer has to spin at 60,000+ RPM to supply the flow and velocity needed...

 

bingo. remeber. you are not just flowing air speed, you have to figure air volume. at the BEST you are only going to come "close" to pushing the amount of air into the motor with the fan as the motor would be pulling itself without the fan. there is NO WAY TO GAIN from it. It's just not going to happen. The motor is a beter air pump then any electric fan will be. Period

 

ah... I like that answer... i'm a true noob to FI... so this was to help w/ my understanding there as well... i've been lurking around FI section trying to accommulate so knowledge there...

Thank you all for the input it is appreciated...

 

no problem, glad I could help
