It is finally finished! After four months of waiting (which was expected for a one-off piece), my supercharger crank pulley is finally done!

First I would like to thank Shawn B at Unorthodox Racing for all the help and great service he has given me! Truely a great person to deal with!

Specs:
-Front 6-rib section for alternator and power steering pump is stock diameter and pushed out 14mm further from stock. I have made the spacers and gotten longer bolts already in order to push out the accessory components to match the offset of the pulley for perfect belt alignment.
-Rear 8-rib section is for supercharger drive belt. I do not run an A/C in my car so this is soley dedicated to the supercharger. It is the factory A/C drive diameter. I did this so that I can run a larger pulley on the supercharger and have the same boost as a smaller pulley (in comparison to stock Vortech kit) which will help eliminate belt slip.
-Weighs just slightly more than the normal Unorthodox crank pulley and is much lighter than stock.
-Has timing notches

 

Here is my Bell Intercooler that I have also. While it is not massive it is more than large enough for my power goals and will flow a very nice amount of air due to the internal baffeling and multiple short rows. Also has bead rolled inlet and outlet to help prevent couplers from poping off. Thanks go to Gerhard Schruf at BIC for helping me out and being a pleasure to deal with.

 

Does this work with a vortech???? how much more boost did you gain??

 

Pulley looks sweet !
Waiting to see the outcome !!!!

 

**** my couch!! The pics dont work for me..

 

Nice work UR. And nice work to you. Cant wait to see the final product

gOOd ****!!

 

Haven't put it on my car yet so there is no telling what boost levels will be. I am making a custom supercharger kit if you search my previous threads so in all honesty there is no telling what my boost levels will be. I am going to be running a 3.25" pulley to begin with on the supercharger. However, since my piping is shorter than the stock vortech, my intercooler is different and my crank pulley larger there really is no way of telling right now what boost the 3.25" pulley will put me at. I don't see it being a problem to hit upper 300's with this pulley though.

 

looking good man. i like how you got the wider belt going for the supercharger.

 

On top of all this for less belt slip, my belt will be in the mid 300 lenght so it will be very short which will help reduce slip. I have a 330 8-rib avaliable and some above 360 so I am hoping that I can get one to fit or I may have to play around with idler diameters and what not.

Phunk, I need to get a connecter for -6AN fuel line to the stock pump assembly from you one of these days.

 

looks very good. i enjoy seeing custom projects taking a different angle. look forward to the results.

 

Thanks for the kind words everyone!

 

All my intercooling/intake piping is on order along with my hose couplers and should be here by the end of the week.

I just got done bending and fishmouthing the tubing for the main part of the front end and where the intercooler will be attached. I should have a complete update within the next 2-3 weeks with some pictures of the tubular front end (minus radiator support), piping done and routed (plus bypass valve and additional fittings welded in and bead rolled ends for secure connections), supercharger completely mounted and spaced correctly along with all other information that I have supplied already such as additional mods and fuel system setup.

One thing that has changed is the V-mount is still in the air. The main reason I am thinking I may not do it is there will be a risk of having too small of a radiator unless I go against the traditional mind set of intercooler on top an put the radiator there.

I am thinking that to begin with I may put the intercooler in front of the radiator like normal but the piping should still be significantly shorter. I should have some updates on that soon. At a later date I can switch the setup quite easily to a v-mount when I am comfortable with my research.

Another thing that I will have provisions for is a manual boost relief valve(s) on the piping that will act just like the wastegate setup that some have tried in order to run a smaller pulley and have boost earlier and then bleed excess boost up top. I brought the idea to the table for the company I work part time for (928 Motorsports) and we decided to test it on a supercharged Ferrari and it worked great and the car is running strong. Even better is that the modification was under $100 to do unlike the wastegate mod that many have done.

I am also working on converting my front bumper to a quick realease setup with quarter-turn dzuz fasteners.

 

Teasers :





Don't worry, that stock power steering cooler is going to be gone soon and there will be a PS cooler on the passenger side "wing" and a oil cooler on the driver's side.

Gonna start playing around with the piping and intercooler/supports and then the radiator and supports.

Stock crank pulley is still in for mock up purposes. Belt size is a K080370 so it is short. Gonig to test it without an idler pulley similar to how people like Audible run their alternator and later I will put a larger idler pulley on the slack side to get more contact if needed.

 

nice. Belt slippage should be low even with a small pulley. 33% more ribs and no extra accessories being driven in conjunction with the sc by the dedicated belt.

very nice!!!!!!!!!!!!!

If I still lived in NC I would give you some beer to help me... lol

 

help with what? you seem very capable with everything your doing. I really admire the custom work youve done.

the quick release bumper sounds nice! think itll be easy to replicate?

 

Lol, I was joking about your sig and I used to live in North Carolina when I was young.

When I get time to devote my attention to the the quick release I will let you know. I think it should fairly easy to duplicate since it will replace the black bracket that goes from under the healight to under the fender that has to bolts that go through the bumper.

I just think it is necessary for my car since I work on it so much lol.

 

Just some more pics witht he pulley installed and my solid motor mounts:



My new motor/transmission (actually the 2JZ/Turbo 400 we took out of the Probe to build this winter):

 

Your getting there.....good job !!!!!
