School me on supercharging a 360
remember with pump gas 93 octane will only support 9 lbs of booost with out a computer controlled engine,,
and when choosing a roots type super charger you need to rememeber,these were designed for diesel engines so the formula is this
6 .71 = 6 cylinder x 71 C,I.
8.71 = 8 cylinder x 71 c,.i.
when converting it to a gas engine 6x71 = 426 thats the engine C,I thats the biggest gas engine it will work on making boost and not over heating the engine,,,
all the roots type you see from BDS and such are new offf the shelf units made to be effective on a gas engine,,and made to look show pretty,, but they are also most all of them the small bore case,,
dyer is the guy that started the street super charger movement back in the 1970s,,,but they were converting real GMC super chargers off of diesel engines full size true 6.71 cases,,my dyers blower is a 1965 GMC unit,thats why if you look close it is not as pretty as a off the shelf made for the street eye candy,.,
BDS boost chart is a guide and not 100% accurate,, boost figures depend on real time compression,,not advertised compression,, real compression comes from the piston and chamber size of your heads,,
if you dont have your motor CC ed by your machine shop before assembly your only guessing at what compression you really have,, but you can always put a boost guage on and hammer it,,see if you can read the guage while driving on the street,, no so easy in my car LOL,,,
ive never had a good experience wit hthe people at BDS,, ask 10 questions you will get 20 incorrect answers,,
pick up a copy of street super charging and read it,,you will learn a lot,,
