7twentyguy Posted March 20, 2017 Report Share Posted March 20, 2017 Has anyone tried a hypercharger intake (Harley) on their Z24 motor? It has that old school bug catcher look and the butterflies open and close by vacuum. I picked one up over the weekend. Has anyone done this before? 1 Quote Link to comment
Crashtd420 Posted March 20, 2017 Report Share Posted March 20, 2017 Interesting idea.... had to look it up to see what you were talking about.... if I was gonna try it my only concern would be those vacuum butterflies not opening properly.... not saying they won't but that would be my first concern... Do they remain open once running? What popped into my head was make the butterflies mechanical and sync with the carb butterflies and poke it through the hood like a Mini blower...

7twentyguy Posted March 20, 2017 Author Report Share Posted March 20, 2017 .Exactly my thought, fab up a short intake tube, cut a hole in the hood and you have a mini blower look. Except for the offset. Quote Link to comment
Crashtd420 Posted March 20, 2017 Report Share Posted March 20, 2017 Before i bothered doing anything I'd first hook up a vacuum to see how those butterflies operate... I have no idea about your vacuum set up or what the it takes to operate those. last thing I'd think you want is them closing while your driving. As I stated worse case convert it a mechanical setup.... then the opening and closing will match your carb and pedal... Quote Link to comment
datzenmike Posted March 20, 2017 Report Share Posted March 20, 2017 Just glue it to the hood anywhere you like rather than destroying the hood with a hole. It won't affect your power increase. 1 Quote Link to comment
7twentyguy Posted March 21, 2017 Author Report Share Posted March 21, 2017 If I were looking for a power increase I'd do a motor swap.This is just to have something a little different Quote Link to comment
datzenmike Posted March 21, 2017 Report Share Posted March 21, 2017 Don't ruin the hood doing it is all. Double sided tape maybe but make it reversible. 1 Quote Link to comment
7twentyguy Posted March 21, 2017 Author Report Share Posted March 21, 2017 I won't be using my original hood, I picked up a spare last year its got a few small dents. If it doesn't look good it's not a big loss. Before anything gets cut I need to see if I can get the hypercharger to work properly, if it doesn't work I'm only out for the price of the part and my time and effort. 1 Quote Link to comment
datzenmike Posted March 21, 2017 Report Share Posted March 21, 2017 It's an air filter it doesn't 'do' anything. Well other than filter the air I guess. You have an air filter complete with cold air inlet from the high pressure area in front of the rad.. Where are you going to connect the valve cover hose to it? Quote Link to comment
7twentyguy Posted March 21, 2017 Author Report Share Posted March 21, 2017 I've got a small filter to fit on the valve cover, and you're right it's only an air filter. The whole reason I'm sharing this is if this has been done before,is the vacuum on a Z24 strong enough to hold the butterflies open so the air filter can do it's job. I put a straw over the tube where the vacuum line will go and I sucked as hard as I could, it opened the butterflies about halfway. Need to try plugging it into a vacuum line on the truck and see if it will open all the way. Quote Link to comment
Lockleaf Posted March 21, 2017 Report Share Posted March 21, 2017 A solid z24 will put down something like 18-20 inches of vacuum. If yours is tired it will ship less. Find out what those butterflies take to hold open. Run a vacuum test on your motor. Quote Link to comment
DrvnDrvr Posted March 21, 2017 Report Share Posted March 21, 2017 Mike, it's just a Sacratomatotown thing. 7twentyguy, that breather would look REALLY COOL popped outta your hood.Just my $.02 Hell, I still got snow in my yard. Quote Link to comment
G-Duax Posted March 21, 2017 Report Share Posted March 21, 2017 Even if the butterflies open as they should, the air filter inside is tinny, and if anything will make less power. I'm with Mike, glue it to the hood, maybe glue 4 of them to your hood, and look really trashy. Quote Link to comment
datzenmike Posted March 21, 2017 Report Share Posted March 21, 2017 I don't see how engine vacuum will hold the butterflies open. Engine vacuum is highest at idle and slowing down. When the engine is floored there is very low vacuum. Basically it will open when idling and close when floored. Must be spring loaded holding it open and use vacuum to close it. I looked this thing up and there was a whole page of complaints about getting it to work (on a bike).... problems driving in the rain..... Wow $300 for this??? I'm in the wrong business.

distributorguy Posted March 22, 2017 Report Share Posted March 22, 2017 I've actually tested air cleaners for Kuryakyn on my flow bench. Their designs are mostly well thought out and flow air VERY well. But any time you add a throttle plate to an air cleaner, you have several factors that can and eventually will impede proper flow. Even if the air cleaner's throttle plate is tied directly to the carb's throttle plate, you disturb the air entering the filter. If the throttle plate was switched to open and STAY open when the key is on, then you may have a solution? Quote Link to comment
datzenmike Posted March 22, 2017 Report Share Posted March 22, 2017 What's the purpose of extra throttle plates anyway? to make it look like a dragster??? I'm thinking clown shoes. 2 Quote Link to comment
7twentyguy Posted March 23, 2017 Author Report Share Posted March 23, 2017 Thanks for all the positive input lockleaf,DrvnDrvr & Distributorguy. It's the reason I posted in the first place, hell it's the reason I wanted to be part of this community. I always valued your opinion datsunmike I think you're a pretty bright guy. I was hoping to get some positive feedback from you but I guess you're having a hard time getting past what you believe is right or wrong for my truck. When it's done and if it works I'll post a picture. Quote Link to comment
Crashtd420 Posted March 23, 2017 Report Share Posted March 23, 2017 If you like it doesn't matter what anyone but your self thinks....its just looks that can be reversed... its nothing that's gonna cause an unsafe driving condition.... Quote Link to comment
distributorguy Posted March 23, 2017 Report Share Posted March 23, 2017 Like top fuel dragsters, throttle plates are on the air cleaner to keep things out of it when the engine is not running. Theirs are directly attached to the real throttles, but typically on a cam that opens the vent blades at a rate faster than the carb blades. Tricky, eh? Don't ever let the intake choke the carbs, or disrupt the straight flow of clean air. Quote Link to comment
datzenmike Posted March 23, 2017 Report Share Posted March 23, 2017 It's understandable that when it comes to form over function I try to save people from themselves. Of course you can do as you please. I'd just rather that you didn't cut up your truck for a 'look'. Let's face it, it IS just for a look. When you are done and have exhausted any chance of this thing being of any use, put the good hood back on and pass this on to a honderp owner. Lesson learned. 2 Quote Link to comment
720inOlyWa Posted March 24, 2017 Report Share Posted March 24, 2017 Thoughtful of you, Mike. And I appreciate it. One resists saying anything about taste and form, because it is a free world. But LeCorbusier had it right, form follows function. And, it seems to me- just my opinion- both the form and the function of a stock 720 are really just fine. A lot of youngun's want to drop their trucks on the street, which is up to them, but it negates the form ‘truck’, and, especially as the original designers had intended. I say this and yet I am considering grafting a perfect 84 KC bed onto my 85 cab and frame, just because it is perfect. Not that my truck is collectible by any means, but that pretty much nukes its originality. I still prefer my trucks at least functioning as intended- as trucks. Quote Link to comment
datzenmike Posted March 24, 2017 Report Share Posted March 24, 2017 If you have a race car, a real race car, it will look like a race car. It's function dictates it's form. 1 Quote Link to comment
willz Posted March 24, 2017 Report Share Posted March 24, 2017 First observation is this thing is sticking out of your hood and it's raining, and you're sucking a bunch of water into your motor (we get a lot of rain here in Washington). And my second is I don't understand how this is going to flow more air into the motor when all you're really doing is adding more piping. Engine bay temperatures while moving are quite cool surprisingly. Quote Link to comment
