cheers tim, im thinking about down the track going a raptor for my vy but was just keep to see the difference between vy-vz
06VZ
The Raptor kits are inclusive of all parts, we have a power range of between 200 - 245rwkw and its more dependant on the particular vehicle than anything else. So essentially we are talking from 290 -325 Engine Kw. We have had reliability of engines and gearboxes although its nearly impossible to get the 5speed to shift under full power, the computer always wants to shut down engine power for a moment and then shift, this makes it difficult to get any kind of quartermile time.
The kits are standard with Front mount intercooler system now.
Where are you located? If in Qld then you can have a drive in drive out option otherwise we might have to search out a fitter near you that has VCM suite software to load and trim the tune for you.
More questions .........

I have attached a VY Intercooled chart and will add a link in here for VZ Intercooled since the forum thingy informs me I cannot load the VZ chart twice in the same thread.
VZ 175 manual chart (no extractors etc) VZ Alloytec Kit Development
VZ 190 Auto - extractors/exhaust mods and intercooled VZ Alloytec Kit Development
A suggestion to anyone wanting to know everything SC Alloytec, its all in this thread ...... just start reading, dyno charts etc etc .
Raptor Superchargers - Boosting S1/S2 3800's, Ecotec's and Alloytec's
why does the vz 190 have so much more torque?
i would say due to the diff in the motors
Both the VY and VZ had stock diff ratios, to be honest I do not know the original ratio of a VZ 190 5sp auto
The Alloytec is actually producing more torque hence the higher power figure
TAKE NOTE, the VY torque is engine torque, the VZ is showing torque at wheels (which has been multiplied through the drivetrain)

ohhhh that always helps
The diff ratio for the 6sp manual vz v6's and 5sp auto v6's is 2.87
Chuck Norris destroyed the periodic table, because he only recognizes the element of surprise
why has the vlc kit been taken off the raptor website?
Very sorry
When I updated I removed more stuff than I should have. VLC remains an option for EVERY Raptor kit, ie you can have the liquid cooled supercharger with every kit.
So whether it be Ecotec, Alloytec, BA Falcon, Magna V6 or Subaru supercharger system you can option to have VLC with any of them.

this might b dumb but wats VLC?
Hmm
I need to do a LOT more marketing on this little number
VLC ( Raptor V Liquid Cooled)
This means the actual supercharger has a water jacket on the snail and its own radiator and pump - cooling system. The charger actually runs at near ambient temps rather than 50C hotter.

Hmm..
Still saving....
There is going to be some serious dynamite unleashed in this thread possibly in the not too far distant future.
First thing up is we have been given the opportunity to test one of those aftermarket alloytec manifolds on Bren's VZ, place is at MSA's workshop, time still being set and tests will take place with CPR owner on hand to view and assist with the testing to be sure its all spot on.
Second thing, bigger fish are frying .......... some barriers that have stood in the way with tuning "could" be about to removed.
Both items are definite "must watch progress" items for the Alloytec owner who is looking for MORE POWER/TORQUE

sounds awesome tim cant wait
So who's gonna break the news Bren ......... hey hey hey
Will see what you write up first before I have anything to say

whoa, so the testing with the CPR6 has already gone ahead???
Judging by the "hey hey hey" it can only be good news!
Lets see, signs are promising in the communications I have had, of course I am 1000km away from the action so going on dyno operator feedback

Used to run a supercharged car with a belt setup like that and had nothing but trouble with belts slipping on the blower pulley and loosing boost. Even tried to put idler pulleys before the snout to give more wrap around the blower pulley but to no avail.
Ended up using a Gilmer drive setup with a pulley on the harmonic balancer, which would mean moving the blower assembly forward to the front of the car more.
Not saying your system wont work but with my findings those belts are no good IMO.
Genreaper
What brand of system did you buy, who did you buy it from?
You will be suprised to learn that the Raptor Alloytec VZ kit has zero belt slip issues, you may be further suprised that NO Raptor system suffers belt slip no matter what brand of vehicle it is bolted to. We only use 5 or 6 rib belt drives for up to 13psi, if you can't drive a charger at 12psi with no belt slip using a 6 rib belt then the system is poorly engineered. A 6 rib belt is good to power a supercharger that will provide nearly 500kw with ease, its not done often but .......... it can be.

It was a Toyato Supra Supercharger.
It was not a Kit it was on a full custom Drag car running 10 flat.
Mechanical fuel Fuel Injected, supercharged running Methanol.
500 HP 202 red motor.
It was running a 5 Pitch belt.
Then i whacked on an AutoRotor Supercharger, same problem again.
It was better with an Idler Pulley right near the supercharger snout Gear but still not much chop.
Only way i ended up fixing it was to use Gilmer drive.
The car was far from Poorly Engineered, maybe if you are using it for the hype, but when it comes to making power, i beg to differ. Chewed belts like they were going out of fashion. Was overdriven slighly on origional specs. Engine RPM up to 8000RPM usualy shifted at 7650RPM
Sure it may work to a part of it potential, but when its sliiping and not consistant you will never get a propper tune no matter how it sounds or goes.
Car run over Half a second quicker when converted to Gilmer drive, no more belt issues.
Maybe it will work on a street car with average power and setup but if you want performace the Belt system you are running is not the ideal setup.
No i am not taking the piss i am giving you facts and the experiences i have been thru with a similar setup.
Here is the car it was Run on.
Mind you running a street car to 6000 RPM may not be affected as much but in a race setup the problem is compounded.

All good
I can assure you and also our customers can too that no Alloytec, Ecotec or 3800 kit made by Raptor ever gets belt slip.
Right this moment the only thing we would like to improve with Alloytec is getting a better flowing throttle body/manifold and exhaust side of cylinder heads. If you got some good ideas and proven suggestions on that one go right ahead, this is an Alloytec SC thread for the benefit of bring newest and latest news/ideas/results to the Alloytec scene.
For now we are not even remotely limited by belt drive performance, we need more airflow at the T/B

Fair enough, i am interested in watching this setup and i had fitted a few Castlemaine Rod Shop setups and they were pretty poor with results on early model Buick motors, even tuned.
With the setup i used i actualy fitted dual throttle body's before the supercharger intake and not after in a blow thru system.
