john555 0 Posted October 22, 2008 Report Share Posted October 22, 2008 ok can any on tell me how fast the charger spins at what boost, as iv found up rated bearings but cant figure out which one i would need i only want to run 20psi max i know the pully would be tiny but im gona machine some uprated pullys also who in the uk can rebuild the vortech vf engineering charger Link to post Share on other sites
Eat this 2 Posted October 22, 2008 Report Share Posted October 22, 2008 its limited to 20 psi due to the compressor blades going supersonic and ruining the airflow mate imho youve got no chance of hitting 20 psi with the ribbed normal belt i reckon youd have to make some kind of toothed belt/pulley combo i have enough trouble at 12 psi Link to post Share on other sites
xyber 1 Posted October 22, 2008 Report Share Posted October 22, 2008 If I was going 12psi or more Id sell my V9 and swap to Rotrex mate, much better solution than chucking money at a high boost V9 setup and never being 100% happy Link to post Share on other sites
john555 0 Posted October 22, 2008 Author Report Share Posted October 22, 2008 i was thinking about increasing the other pullys sizes meanin i could use say a 8 psi pully to get 18psibut toothed pullys are another idea i could look at but would take a lot more time to machineand i want to stick with my v9 for now as it would only cost the pric e of the bearings and a remap to run the extra boost plus i love the sound of this charger Link to post Share on other sites
xyber 1 Posted October 22, 2008 Report Share Posted October 22, 2008 may be of use to you mate http://www.superchargerrebuild.com/?page_id=6 Link to post Share on other sites
john555 0 Posted October 22, 2008 Author Report Share Posted October 22, 2008 ah cool thanks mate im guessin if i just go for the top bearings i shouldnt need to worry about them giving up ill probly only aim to run 17 18 psi but id rather be safe than sorry Link to post Share on other sites
xyber 1 Posted October 22, 2008 Report Share Posted October 22, 2008 yeah best route is definatly over engineering it, nice and bomb proof, with 20psi being the max, realistically 18 psi is probably as far as you would want to take it probablyI think 20psi is approaching 65,000 rpm, seem to remember seeing those figures back along and something like after 50,000 rpm the efficientcy tails off quite sharply so will sap more power to run Link to post Share on other sites
