PINK71T/A ok what kind of s/c do you have ? most s/c come in at 5lbs to 8lbs of boost. from your info. you gave. i would say 6lbs of boost. you should use blower head gaskets and dont go over 9.5 to 1 comp.and use a 180 or 160 therm.stat. heres mine
thanks cmyindy |

You might want to accidently lose that 66 intake,its real performance drop,try a 68-71 if you must run a cast iron unit......PRO.....(have plenty cheap if you need one)

I really Have no idea who made it or what it even was
used on i found it in a box of Hodgepodge parts to diff vehicles Heck it might be off a diesel who knows The pics of your supercharger look huge compared to the size of this S/C on the side of it it says AIResearch M10 and on the serial number tag says Garrett ?? Diesel ? |

blown
I run a 6/71 blown 383 on the street at 7-8 PSI of boost and have no problems it runs 10000 miles a summer.If you keep boost below 10 PSI with a 7:1 motor,from the looks of your description you have about 10:1 comp so I wouldn't go above 6-7 Psi of boost max if you don't want to have head gasket or ring problems,also you should use a steel O-ringed head gasket Min if you plan to supercharge the motor (believe me it is all worth it I have put 40000 miles on in 4 years + no problems).
good luck. |

Too much squeeze for a SuperCharger
Yeah, I will have to agree with Bill, but one further. A supercharger heats up your intake charger so you really can't be 100% safe from detonation unless you are well below 9:1 compression.
A supercharger on a low compression stocker (smog motor) is a great combo! The beauty of supercharging is that your intake charger is *pressurized* that means you are not so much concerned with optimizing airflow with porting, intakes and so on. Its under pressure and you are easily able to achieve volumetric efficiency. The concerns with free flowing don't really apply so much on a street performer. In a race build up you are probably running against other supercharged cars, you need all the tricks in the book. I would recommend a cam for supercharging. You want little to no valve overlap because with a pressurized intake charge you are just wasting your intake charge out the exhaust (during valve overlap). Here again a STOCKER SMOG MOTOR is ideal with the exception of maybe forged dish pistons meant for supercharging applications. On a low comp stocker keeping the intake charge under 10 PSI should be plenty safe. Recommended reading is SA Designs STREET SUPERCHARGING book. A Most Excellent read. |

Thanks for all the info guys i think i'll just put The super-
charger idea off to the side right now and get a better intake and headers With my combo listed should i go with a Dual or Single plane (i was thinking Dual for Torque?) and a good set of headers for a E-body i don't want to be pulling them off all the time because of blown head gaskets which header is a good E-body header without Dishing out the Big Bucks!! Thanks Again Guys! |
