Can i run a small blower with 9.6:1 compression?
Can I?
I am not worried about gaining a huge amount of HP but i like the look of a blower.
Here are the specs on my engine:
Power: 430 HP @ 6000 RPM, 430 ft. lbs. of torque @ 4200 RPM
Displacement: 350 CID, 5.7L
Bore x Stroke: 4.00” x 3.48”
Compression Ratio: 9.6:1
Recommended Fuel: 92 Octane
Block: Cast Iron, 1 piece rear seal, 4-bolt main caps
Crankshaft: Forged Steel
Connecting Rods: Powdered Metal Steel
Pistons: High Silicone Aluminum
Camshaft: Steel Hydraulic Roller Tappet
Cam Lift: .525” Intake / .525” exhaust
Cam Duration @ .050”: 218 deg. Intake / 228 deg. Exhaust
Lobe Separation: 112 Degree
Cylinder Heads: Aluminum, 3/8” screw-in rocker studs
Combustion Chamber: 62cc
Valves: 2.00” Intake/ 1.55” Exhaust
Rocker Arms: Aluminum Roller, 1.6:1 Ratio
Valve Springs: 12551483
Balance: Internal
Maximum GM Recommended RPM: 5800
Ignition Timing: Base 10 degrees BTDC, 32 degrees total

Are you willing to up your octane. 9.6 to 1 is already getting up there on iron heads. Aluminum heads would probably be a good investment if you are going to try and run boost.

He has aluminum heads already. You could run a blower, but with non-forged pistons and rods, you'd want to keep the boost low and run the highest octane in your area. An intercooler would be a must and water/meth injection recommended but not required. I'm guessing this is gonna be more of a street vehicle than something going to the track?

He is right on. Sorry I missed aluminum heads in your build list. Water/meth injection would be a lot cheaper then a intercooler set up for a roots style blower. Plus you would get the octane boost to help control detonation.
