Science Abuse Posted January 12, 2008 Report Share Posted January 12, 2008 So, this guy claims: 275cmf 1.2 - 2.3 lb of boost That's not enough to keep up with the sucking of your average engine...but. I've got an 87hp engine and I'm searching for a non-invasive and cheap 100+hp. I know at least one person here did a leaf blower. lol Can anyone help me develop this idea on paper? It's carbed engine 1.6l ohv Question 1: Now, since a carb draws fuel from vacuum, does that mean that I'll have to run a box if I make .001lb of boost? Or can I blow through the carb as long as I keep it low? Question 2: Will I need the boost to vary with revs? I.E. run it off of a transformers that speed up and slow down the electric motor with the engine RPM? Or, since boost= pressurized system, do I just plug it in, turn it on, and provide a weak BOV for when the throttle plate closes? It looks like I can have the power I want in a manner that can be easily removed if it fails. I'm wanting to plan it all out on paper first.

81mercury Posted January 12, 2008 Report Share Posted January 12, 2008 you have to be shitting me!....why not go the intake/exhaust and maybe a cam route first? Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted January 12, 2008 Author Report Share Posted January 12, 2008 you have to be shitting me!....why not go the intake/exhaust and maybe a cam route first? Because cams are $225, and very labor intensive. This engine only has to run for a day. A "power pack" from the only company that makes performance bit for this engine is $600 and only gives 40 more peak hp. I found some BFE lab that state there's 2.2 cfm per hp, so 275 cfm will support 123hp, just what I need. Quote Link to comment Share on other sites More sharing options...

81mercury Posted January 12, 2008 Report Share Posted January 12, 2008 yea spray it if it only needs to run for a day Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted January 12, 2008 Report Share Posted January 12, 2008 I don't like spray and I still say spray it Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted January 12, 2008 Author Report Share Posted January 12, 2008 I wouldn't spend a dime trying to make an 87hp car go fast. I'm not trying to make it go fast, I'm trying to make it less slow. It's no crx, but the showroom weight was 2200lb. "Run for a day" means all day....all of it.

DTM Brian Posted January 12, 2008 Report Share Posted January 12, 2008 I wanna dyno test one of these things. lol Quote Link to comment Share on other sites More sharing options...
verse Posted January 12, 2008 Report Share Posted January 12, 2008 When I dyno'd mine it made 59RWHP and 79FT/LBS. I was going to go the power pack way, but you'd be spending more than just swapping a 4AGE and be making less power. Quote Link to comment Share on other sites More sharing options...
twistedfocus1647545489 Posted January 12, 2008 Report Share Posted January 12, 2008 If you could rig up something similar that draws through the carb instead of being a blow-through, you'll likely have no issues with the carb itself. I have seen some aftermarket and even OEM draw through centrifugal supercharger or turbo systems (albeit not lately). I think J.R. Granatelli had a centrifugal supercharged fox-body back in the day that was draw-through. Maybe you could borrow some design cues from those applications.

Guest Removed Posted January 12, 2008 Report Share Posted January 12, 2008 spray it...very small shot will last some time.2 bottles! and with very small jets(say a 20-35hp shot) the bottle will last for a while! btw im still going to laugh!

I was going to go the power pack way, but you'd be spending more than just swapping a 4AGE and be making less power. Still too expensive and too damn hard to find. However, pick'n'pull is full of 4A-FEs, so many that I stopped counting. Also found a 4A-F and 2 7A-FEs. Complete engines are only $160ish without core.

93_ChargedCobra_342 Posted January 13, 2008 Report Share Posted January 13, 2008 I am going to guess that at their maximum boost level these units move practically no air. I think it will be a waste (of what 70 bucks), but if you think it may work go for it, Ive seen guys put close to a grand in a car and say id doesn't feel any different. These I believe are also use in marine application to evacuate fuel fumes from around the engine compartment before starting the engine.

I actually found it by going to Ben's (Satan) old house for a LAN party one night. I kept asking the people and a year later they decided to sell it to me.
