supercharged H22

[cincy90h22]

This is true, but at the same time, that's a large unprotected rotating shaft running more than half the length of the engine bay. I'd imagine a sleeved shaft, or something along those lines, would be a safer option but the basic idea is the same. If you add a pulley to the end of the shaft then use a small belt to link it to the SC, which would be on some sort of custom bracket, I think it would work.

The only downfall to a setup like that is that IIRC that's a lot of weight added to the crank which, in turn, would decrease power. Granted the SC would overcome the power loss but it's something to consider. Honestly your current setup seems to be the closest way to running this setup properly and efficiently.

all your points are exactly the reason I am doing it my way.. Ive thought about this for years, researched and now Ive finally gotten around to doing it.

Two things I would like to add.. what would to do about applying adjustable tension to the belt connecting the shaft to the supercharger? I would just directly bolt the shaft to the SC. Also, you would still have to move the power steering pump (custom brackets) to keep it and have room for the pulley on the shaft to connect to the crank. Look at pics of the b16 civic with this set up and you will see all the different little things that you would have to custom make now that it is no longer made.

Sure there is a lot more room over by the tranny to work with. If I still had AC/PS I prolly would have went that route. All you would really need is two carrier bearings like our axles are mounted to the block with, and a straight shaft. Hooking it to the SC is a lil bit tricky but could be done fairly easy I think.

Jackson Racing made a supercharger for the h22 at one point.

That's been discussed a fair amount in this thread already.

I thought about that yesterday, it would be quite easy for me to put together a kit of brackets n such, let the buyer pick their own supercharger unit. Anyway, just a thought. The SC does not fit in the power steering location because the air intake sits too close to the exhaust header, unless you want to cut a big Hole in your Hood lol. So unfortunately AC and power steering cannot be kept with my setup. Which doesn't matter to me. Vortech Made a kit for the 97-99 civic B16, using a jackshaft to locate the charger next to the distributer, retaining AC/PS, but has been discontinued.

The idea of locating the supercharger on the transmission side does sound interesting for those who want to retain their accessories and I would imagine the mounting options would be a bit less restrictive. Still, I am very excited about your build.

The brackets was what me and joey were speaking about the rest was just hear say.

[cincy90h22]

No offense but to put together a kit, its gonna be way more than grand for everything. The SC alone would run about a grand (give or take) for a used one. And I wouldn't put used parts in something to sell, too much liability.


Anyway.. updates!
Made extra braces for the SC bracket. Revised the belt/pulley system for better coverage on SC pulley so it doesnt slip. unit completely installed. Charge pipes and intercooler mocked up. Sending to a buddy to tig weld tomorrow. I don't have a tig or I would myself. Sorry no pics, left the camera at home.

The brackets would be a decent idea, i was going to ask but you said you wanted to be unique so i didn't. If one could piece together a full kit for under a grand or so that would be a great investment for decent power.

I searched wikkedv16's name and came up empty on the FM root setup. It seems interesting, but i would like to know more. It could very well be an alternative for my project.

Yeah, he didn't post about it. We talked one on one about it. He's the one that talked me into buying my own supercharger. That kid can talk me into doing just about anything!

Definitely some CB7 History in the making. I see you mentioned 105hp is your expected gain; is your H22 stock? I did some research to see what used Vortechs cost and it seems if you look around long enough, there are tons of deals to be had on those units, and the rebuild parts are fairly "inexpensive". I would strongly suggest that whoever did the fabrication look into making the brackets into a kit that other members could purchase if this project was a success. I'd be interested myself if I could keep A/C. Speaking of, is there any reason why the blower couldn't fit in the P/S pump location? Or is that actually possible?

Flame suit? Why?

The only time people get flamed is when they make the 10,000th "duz ne1 make a supercharger kit 4 r cb7z?" thread
You're actually doing it, which is commendable! I don't know of anyone that has done a centrifugal setup yet in a CB. There's the one famous JRSC on the H23VTEC, and a CD with a custom roots supercharged F22B2. Then there's wikkedv16's attempt at a front-mounted roots blower on his sister's Prelude, which worked until it blew the charge pipes off... That was how my plan was going to go.

Keep up with it. Keep us updated. Good luck!




As for the intercooler, what you have there is essentially a turbo compressor powered by the crank rather than the exhaust gas... so an air to air intercooler will be just as useful for that as it would be for a turbo.

Certainly not the first.

on the snail style I would say yes, unless someone is has done it.
