I know this may sound strange but how do you think a elec. radiator fan mounted on top of a air filter forcing about 1200 cfm. through a modified tbi larger injectors etc.would work.Could use a switch on throttle link.to engage it of course it would require a cowl hood and tweaking etc.I know this is not a compressed air system like a supercharger but maybe it could improve breathing of engine.And it would be cheap if it works! I just woke up so hope this dosent sond to crazy.

Found this on a discussion board.

What you think about this guys??

I too have a 305 in my Firebird and have done all those little things to it. Let me tell ya first off that the K&N filter ain't worth the money and high octane doesn't make much of a differance either but they don't hurt. This is what I'm doing to mine. Hows about 100 hp for less than 100 bucks? Do I have your attention yet? You may have already read this somewhere but if not here it is anyway. Go find a leaf blower or shop vac with a blowing unit, Next get a fuel line splicer and regulater. Mount the leaf blower in your engine compartment some place, Then go ahead and splice your fuel line and install one end to the blower fuel supply, set the regulator at about 3pounds. From there remove your factory breather, make a hose that goes from your intake to the leaf blower outlet do some rigging to where you can control the blower from inside the car and presto! You have a poor mans Turbo Charger! Now if you have TPI Induction which I don't then you'll be fine on your fuel to air ratio, but if not then you'll probably wanna get an after market fuel pump with more flow, Electric is the best. If you are familiar with a cold air box then go ahead and make one of those to replace your old breather. This settup will hopefully let you run high 11's or low 12's at the 1/4 mile strip, of course if you really wanna hall *** then you can do a twin settup, thats what I'm doin. Well Good luck and trust me this is worth a few hours under the hood.


One Guys response to the topic.

Hey maximus-firechicken, aren't most leafblowers 2 stroke and most(all) f-bodies 4stroke? Are you going to mix the entire fuel tank of your car as 2 stroke fuel to run the blower? You're talkin' some duckies there bud$$$$$$$$$$$$ And I'm not the brightest tool in the box, but you left out the part about tying in the pressure side to the top of the tb so that this guy would understand. It may work, but I won't ride with ya.

i found this one somewhere on here and seems interesting but i would not do it

i think it wouldnt work but thats just me

I think thats THE oldest urban legend on this board. That's been around since the black and yellow days if not before.

JRoy91RS

There's a lot of good info in the archives (mostly in the power adder section), that deconstructs this idea and exposes it for what it is. Check it out. It won't work.

Tas

I wish I was in the orginal archives more. I was mostly on the non-tech board that never got archived. I didn't know enough to be on the tech board :P Hard to believe, ay? we had some real brainiacs back then giving advice, unlike now were every dingus spouts their opinion as cold hard fact.

My view on this topic:
It's a waste of time, money, and effort. If it isn't producing boast then it really isn't doing anything except swirling the air. Turbulant air flow is a bad thing for performance, that is why the open element is one of the best designs. The filter straigtens out the air and it flows super smooth into the engine. This is one of the reasons TPI is nice, they have the smooth runners. This is also why the velocity stack and none drop base air cleaners are the best for just about ANY engine!
You don't want large amounts of air just sitting ontop of the TB unless you have custom eprom work to adjust the amount of extra fuel is "pumped" in on a fast throttle blade opening. This is also why some people are having problems with the "lag" when they install an open element onto the TBI. You instantly give the engine more air but since TBI is a speed density system, it doesn't know that it's getting more air. So what happens is you'll get a lean condition which will create a big delay in power. That is why it is recomended you boast the fuel pressure slightly, this isn't the best fix but it helps. Custom eprom is the best thing because a slightly modified engine running speed density system is going to be far from stock. MAF monitors air flow so custom eprom work isn't needed and you usually can't feel a delay after the ecm "learns."
Does this stuff makes sence? I hope I cleared up the reasons why open element is one of the best setups and how you'll only make more power if you have boast or more flow (less turbulance).
One good alternative is to make a ram air setup. With a good setup you can usually get 1/2 a lb of boast around 50mph. It's like 5 free hp after you get up to that speed, it's cheaper than a home made blower attempt, and it will definatly weigh less!
Take it or leave it, prove me wrong (good luck ) just don't flame.

The idea of having another little engine in side your engine compartment does exactly sit right with me. I would never even consider the weed-wacker power adder idea.

are there any advantages to running open element vs. stock setup.. the stock setup draws outside air.. the open air draws a lot of hot air from under the hood.

The stock element is drawing in from one corner of the air cleaner so the flow isn't as smooth as it looks. It might suck in a little cool air but doesn't come close to the flow of an open element. The dual snorkel setup would be perfect for a car making around 240hp! It would be smooth and cool. Anything making more than 300hp is not going to want to breath through a straw. Think of it this way:
A baby vs an adult! Baby has no problem sucking on a bottle and a straw is the largest before it gets messy . An adult can drink faster by just opening mouth and tilting drink and head back ! Same idea in theory. The difference between taking in warmer air is a disadvantage but it doesn't outweigh the flow advantage of the open el. This is why you get a cowl hood and seal it off from the engine compartment. That seems to be one of the best intakes. Either than or install a huge spacer and drill a hole in the hood .

I was tellin' a guy at work about this "idea". After he took the confused look off his face, his first response was this great scenario.

1st guy: Wanna race?

2nd guy: Yea! Hold on a second. (Pop hood. Walk around to front of car. Yank on pull starter)

Sound effects:
Brrrrr...bluh bluh bluh...
Brrrrr...bluh bluh bluh...
Brr...vrrrrrrrrrrrrrrrrrrrrrrr........

2nd guy: (Close hood. Open door. Sit in car) OK. YA READY?

1st guy: What in the hell is that?

2nd guy: Nothin', Why?



I laughed my a$$ off from that visual!!! Especially the sound effects. I never thought of how you would have to start the damn thing.

For some strange reason, I feel like getting in photoshop and see how this crazy contraption would look.

Maybe I'll post the results!
I'm sure it will look SWEET! LOL.

I totally agree with that. I miss the old days when we had some people who knew their stuff, and the people who didn't know for sure, didn't say anything.

I used "Z28Boy's" engine photo, because it was a perfect look for that "blower" I couldn't find a decent pic on the 'net besides that one. Very special thanks to Z28Boy for his photography expertise.

I call it the torocharger. Tell me what you think. Took me 15 minutes to complete. Not a gas blower but electric...see the cord?

I think it would be sweet actually

Hahaha! Beautiful picture! All you need is a 1320' long extension cord!
Somebody wrote in to CarCraft with the idea of using their heater blower motor as a power adder. Marlan's response was that small compressors or fans aren't good at overcoming restrictions or building pressure. I don't think it would flow enough air to justify itself, either.

No guts, no glory.

Posting Image at Power adders board to see what they think!

Update! I am trying project Torocharger on a '79 Plymouth Volare Station Wagon, my friend (owner of a shop) said it was good for 3-4 psi, and he needs a slant6 power adder! Seriously, I wouldn't try it on my car just so fast, but maybe on his ugly car! I will get pictures out when we are finished, could take a few weeks to get pics! But hey, what the hell, you know...
It's worth a try. We are planning on putting a cold-air duct in the grille going directly going into the blower. By the way, Toro advertises 220 miles per hour blowing velocity! Oh, well...nothing better to do this summmer.

*COUGH COUGH COUGH* Whew, who forgot to dust

So this is what happens when you smoke too much crack Id rather put the money towards a turbo.

On a small motor like that Im not surprised it worked. On a large high output 350/383/400+ the leaf blower would probably do little, and may even become a restriction at some point.

That video is really funny but it doesn't prove that a leaf blower adds power. You would likely see those same HP numbers with the car going down the road with the normal effects of an air intake taking place. A car sitting still doens't quite ingest air the same way as it does when it is at speed. How is this TBI related?

lol, j/k i have no clue...

my leaf blowers good up to 210mph hummmmmm....
i should find one more and i could make twice the power oh ya!
