Great time, especially from a vortech.
I understand why you copped a lot of criticism, because people cant look at the big picture really.

For those who dont understand, the reason why centrifugals style superchargers are considered bad is that from a theoretical point of view.... they are. Roots style would have to be the worst, then centrifulgal.

Why? Area under the curve. The boost from a centrifulgal supercharger rises as a square of the rpm of the impeller blades. What this means is that you get 1/4 of max boost at 1/2 the max rpm, just over 1/2 the max boost at 3/4 of the max rpm and full boost at redline only.

eg. If you had a centrifugal making 16psi when the cars redline is 6000rpm, you would see 4psi @ 3000rpm, 9psi at 4500rpm and 16psi at 6000rpm.

This means that you end up with great peak numbers, but bad area under the curve.
i.e.


HOWEVER.
There are a lot of good points too. The main one is installation and cost. It is waaaay easier to fit in a cerntrifugal on most applications and they are about 1/2 the price of a good twin screw blower. Easy to intercool and boost comes out very cool.


Having said that, They are still great times and my hat is off to you.

Great results mate, glad to see some 1UZ's in this time bracket running that kind of MPH :-)

---
I agree Steven, centrifugal over old school Roots designs for sure. Cheaper, easy to intercool and much less of a 'heated' design (ie. can be kept relatively cool). Results are a lot more consistent also.

Really interested in going down this route, What are the things needed for this over the M90 supercharger kit?? is it direct bolt on with low boost??

You'll have problems running big boost with the factory computer unless its tuned with a piggyback device of some sort. I can tell you first hand that the OEM ECU is very protective of its engine and most supercharger installations are missing out big time just running with the factory computer and a fuel reg.

I recently installed an Emanage ultimate on Peter Taplin's supercharged UZZ32, it will be tuned soon! complete fuel adjustment via injectors, full ignition control, additional map sensor input = affordable performance and reliable tuning without the dramas. Its working with every feature enabled, something i've never heard of done before on a 1UZ! Needless to say its an exciting step forward, especially for those that were considering fully programmable units but wanted to keep the creature comforts the factory ECU caters for with the 32'.
