Blower Ratio for Boost
I am interested in increasing the boost on my motors(540s) and was wondering if someone could tell me the combos that would do this? I have 871 BDS blowers, 3 in. Gilmer belts with superchillers and would like to have 10 to 12 lbs boost. what pulleys would put me in this range?? My top pulley at present is a 55 tooth.Buttom unknown around 63 nearest I can remember.
Appreciate any help you guys can give me !!
Thanks

The Weiand technical info says:
If you have 454's, 5% overdrive will give about 11 lbs
If you have 502's 15% overdrive will give about 11 lbs
If you have 540's 25% overdrive will give about 11 lbs
I think this values is without chiller.
Here is a ratio chart.
