And so it's begun. after already having built a turbo setup and learning a hole lot from it. Im back at it again. This time, its a roots style supercharger mounted right on top of the 3uz. The reason why is I'm going after the daily driving fun factor of the instant torque the roots blower provides. especially since I have the dragon tc to really build up some torque when the throttle is mashed. So I've been on the fence about either buying the 2uz bullet cars supercharger intake manifold or building my own. I determined it would be much cheaper to build my own and it'd be a better fit since the bullet cars manifold is 5 1/2 inches tall including the top plate. that's not including the other five plus inches the m112 supercharger height is. well over 1 1/2 higher than the factory hood will allow. So, bought a older model 2001 2uz intake manifold with injectors and fuel rails. it will work perfect because the runners are individual and are about 4 1/2 inches tall so they'll give me plenty of height to work with. basically, chop off the top portion of the intake. so measure from the bottom of the flanges and go up 4 1/2 inches and probably use a band saw and make on clean cut all the way across. but before doing so, make a jig that the intake can bolt to so that when the cuts are made the two separate pieces can now be rebolted back onto the jig plate. than the simple task of make basically a box that measures about two inches tall. the aluminum plates will be coming from a place call "onlinemetals.com". they sell .375 thick plates of cast aluminum for fair prices. couple of pieces of that that measure 12x24 and some careful measuring and cutting and ill be able to fab up a manifold that the supercharger can bolt to . As soon as I get the manifold in from ebay ill begin the making of the jig and the first cut. ill keep ya'll posted. thanks.

 

Really looking forward to this! Hopefully everything works out smooth and maybe you can make me a manifold for mine in the near future

 

f'in sick!!!

 

Yes, this will do just fine.

 

Dopeee, u are my hero


Any updates?

 

Woah man u read my mind, notice how we posted at the exact same time

 

Ya im in the process of making the jig that the supercharger manifold will be bolted to while its cut up and welded on. I have to make sure its precise when it fits back on the engine. And lucky me, at work we just had a 2003 tundra with the 4.7 come in for an overheat issue which ruined the rings on number six. so were putting a new engine in it and I get to keep the old motor so now ill have a mockup engine on a stand that I can use while I build the manifold. if all goes well, I will make more manifolds for sale if clublexus allows me too but thatll be down the road.

 

So I made the jig for the supercharger manifold today. Basically it will hold the two bottom pieces in position after the top half is cut off and the custom box is made and welded in place. Im now on the hunt for a band saw that can cut horizontally so I can make a precise cut across the manifold. I took some measurements today also buy removing my intake and determining how high the front coolant crossover pipe is and how high the manifold will have to be fabricated to be above it but still be below the hood so the pulley can clear. So it's coming along nicely.

 

we need a like/thank/godly button of some sort on this forum!!!

great work!!! if you can get this to work on the 430, i may be coming your way once you make more manifolds!!!

thanks for pioneering this!!!

 

Agreed^
I'm definitely subscribing to this thread...

 

So I had free time at work so I yanked the intake manifold off and proceeded to place the supercharger on top of the engine and begin adding blocks of wood under the supercharger until the pulley almost touched the hood. The purpose of this was to get a measurement of how much intake manifold height total I can get and still be able to mount the supercharger on it and close the hood. keeping in mind the pulley is the stock size that came on the cobra which is 3.5 inches diameter. planet soarer calculates and has proof that that pulley with our crankshaft pulley on our cars will make 6 psi. Just what I'm looking for. TO START!!!!!! So all said and done I have come up with a solid height allowed for the custom supercharger manifold which is 3 1/2 inches tall. Now that I have these numbers I know just where to cut on my 2uz intake Im using. So far so good, I'll keep pics coming as progress is made.

 

:drool:...

 

dude!!! sick build, looking forward to the outcome !

 

Yup, hopping on this bandwagon- I want one, too.

 

In the process of ordering the aluminum materials to fabricate the intake manifold out of. its 6061 billet aluminum and is ideal for automotive applications.
