supercharged H22

[motobmx105]

Cool build! What are you useing for tuning? How high are you reving it? Looking forward to dyno #'s!

Here is a similar setup but like said you have to have it stick out of the hood lol

nice valvecover.

Throw a set of vice-grips on it til you get the restrictor... Can't hype us up with all the major progress and then let us hanging for 2 weeks... Hell throw us some pix at least :P

[cincy90h22]

Unfortunately still waiting on my oil restrictor.. should have been in last week.

[bigpoppa694lyfe]

Where's the updates??? I'm stoked to see this thing finished

[cincy90h22]

That setup doesn't look too bad height wise.. except for the dryer vent intake LOL.

I am using crome.. can't tell you exactly how high I will Rev it, depends on where the power band ends up, realistically 7500, no higher than 8k

Sweet bro, keep us updated! Can't wait to see her up and running!

[cincy90h22]

My cams are not a full blown NA cam. Its a tuner series cam, designed for better high end power. The cams aren't aggressive enough with lift and overlap to create an issue when boosting.

Update:

Its alive!!! Still have charge pipes to run when I get all my couplers. And waiting on injectors. Then tune. Going on vacation next week so all my parts should be in when I get back.

If you look at my sig, I am not stock, and currently pushing 195 to the wheels. I hope to see enough gain to put me in the 300 range.

toycar - I already have my belt size and tensioner devices figured out. I don't see the need for another spring loaded tensioner, nor is there any room LOL. The charger itself cannot be slotted to rotate, its held to the bracket with 6 bolts.

N/A and forced induction are two completely different animals. Lungs vs gills.
If you have upgraded N/A camshafts, you'll be blowing your compressed air/fuel mixture right out the exhaust ports, wasting a good deal of it.
Header and exhaust will be useful for either, though, as will any headwork you may have (I have not looked to see exactly what you are running yet.)

I'm glad u are not doin this for HP numbers.. its all a guess rite now... you are doing this. Just because you can like you said.

I wouldn't want u 2 go thru all this and not hit ur hp range u want.


I am clueless on different sizes this and that on Turbo's, s/c, you guys know your stuff. I wish I new more so I can contribute knowledge wise, instead of askin questions =/.

[cincy90h22]

That's actually how I wanted to do mine. Move the alternator down to the AC position, and have all that room up top for the supercharger.



Is this really going to make 300hp? The H22 only makes 165hp or so to the wheels in stock form. 300hp will be damn near doubling that!
I expected my M45 (which is a COMPLETELY different animal) to make maybe 220-230 max when I installed it.

Really depends on the compressor. I don't personally think it'll hit 300whp, but Im not sure how much this thing flows. Its certainly not impossible.

Especially if he plays with the pully sizes to get the charger adjusted into his powerband.

[darkfusion42]

I have thought about something similar using a modified comptech kit for the 3.2 cl/tl, just reversed. Placing the shaft so the pully side matches ours would place the supercharger right where the battery would be, a battery relocation would solve that then the supercharger would be on the intake side. Haven't done much measuring though but seems doable.

[deevergote]

what about the opposite positioning? ie the alternator wayyyy down low and the sc up a bit higher on the top ac bolts and original alt bolts?

That's actually how I wanted to do mine. Move the alternator down to the AC position, and have all that room up top for the supercharger.

I dig it!


I read a few posts back something about pulley sizes and working with belts and shit.

There are a lot of companies that make custom belts on request, maybe contact a few and have something specific made for you.

For tension on the belt, I would consider a spring loaded auto tensioner or a crescent shaped opening in the bracket on one or two bolt holes so you can rotate the charger to apply tension, then bolt down. If you use a crescent design, use quality hardware, thread lock and locking washers. You wont regret it.


I ran out of injector(dsm 450's) before 300whp too. I run e85, but I was logging 25-26lbs/min at the time. No where near 300whp.

Im curious, do you have a compressor map for this charger? If so, doing some basic math will tell you what size pulley to buy for it to get into peak efficiency. The size of the pulley on the crank that this charger was designed for may have been much smaller/larger(diameter) than yours, and if it was than you will have a hard time getting this thing spinning at the right speed to make ideal power at the right RPM. You dont want this thing to have a hard time holding pressure all the way to 7,500 RPM, and you dont want this thing to wait to build pressure until 7,500 rpm either.


Basically, if you know the RPM you need to make in the compressor for the charger to get into its peak efficiency and you know the size of the pulley on your crank and the speed of the crankshaft-you can use this to determine the required size of the pulley on the charger to get you into peak efficiency (charger) during peak torque(on H22)

Pairing the two will make much nicer power band.

I dig your approach, If I was to charge an H22 I would have done the exact same thing. I've actually mentioned it a couple times that this is exactly how I would do it, Im happy to see it getting done.
