I sent an email to Unorthodox asking whether it would be possible to have some kind of UP will a supercharger (in particular by tibby's) - because the currently offered ones would worsen performance.
However it is possible to get one custom made and therefore get the benefits of an UP.

Here is the reply from UR.

"A custom stock diameter crank pulley would have to be made in order to
maintain the same boost as you currently have because an underdrive pulley
would reduce the boost.

Custom Pricing Schedule

Alternator Pulleys: (single belt, double belts start at $250)
-3 to 6 rib starting at $175
-7+ rib starting at $200

Crank Pulleys:
Single belt
-3 to 6 rib belt section starting at $275
-7+ rib belt section starting at $300
Double belt
-3 to 6 rib belt sections starting at $325
-7+ rib belt sections starting at $350
Triple belt
-3 to 6 rib belt sections starting at $375
-7+ rib belt sections starting at $400

Power Steering Pulleys: (single belt, double belts start at $300)
-3 to 6 rib starting at $200
-7+ rib starting at $225

Water Pump Pulleys: (single belt, double belts start at $300)
-3 to 6 rib starting at $200
-7+ rib starting at $250

General machining w/CAD design is billed at $50 per hour. All machining is
done by our in house prototype machinist. He is a Class A german machinist
with over 40 years of manual machining experience, from submarine to
aircraft parts. We use only the finest manual lathing machines available
today, impeccably maintained to hold the tightest tolerances you've come to
expect from Unorthodox Racing Inc.

CNC Custom parts are two to four times the quoted prices for custom manual
made components due to the higher cost of the CNC equipment and the
programming time involved in order to run custom CNC parts. Set up time for
custom CNC parts can take 5-6 hours not including the additional
programming.

Thanks for your interest,
URI"


I have to say that I wasn't aware that other pulleys were available for the Tiburon. Plus would the outlay for a custom machined pulley be worth it for the extra bhp and any potential problems? (seeing as no-one can really confirm that an UP is a safe mod)

instead of going through all the trouble.. just change the blower pulley and make more boost.. that should be a much cheaper method of getting an extra 10-20 hp.

Good point. Just have them make a smaller pulley for the S/C. I have seen this done before when the crank pulley (or what everone drove the S/C) was left at the stock diameter. Just have them reduce the s/c pulley by the same percentage as the crank pulley. That will maintain the same ratio and therefore the same boost.<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

Hah hah they're trying to sell you the more expensive option.. no real surprise there I spose.

Just change to a smaller diameter blower pulley.

what about having near stock size pullies, just at a must lighter rate, in combination with smaller sc pulley, etc. That's an expensive upgrade, but will allow you to keep your options (ac) and still free up hp.

I have considered having lighter, but same size as stock pullies. I have also though about reducing the diameter of the s/c pulley and running at 8psi instead of 5.

But to be honest, I want to see if the s/c will run trouble free for atleast 6 months before messing with anything.
