Can I supercharge my engine?

Here's the combo:

it's a 342 ford racing block

# 5.0L/302 2-bolt main M-6010-B50 HD Sportsman block
# Hypereutectic pistons with valve reliefs for N351, GT-40, and other inline valve Windsor heads. Valve notches approximately 6.5cc. Piston to deck .000" Nominal
# 3.40" stroke nodular cast iron Stroker crank
# M-6200-D50 SAE 4130 forged steel connecting rods
# Federal Mogul rod, main and cam bearings
# Balanced for 28.2 in./oz. early style damper and flywheel
# Assembled and ready for your heads, cam and timing chain set
# M-6013-B347 347 CID and M-6013-A342 342 CID. Stroker crank kits also available. See page 69

The heads are Dart Pro1

62cc chamber volume

The intake is a Weiand X-CELerator

I have a BIGGS carb, 650 double pumper
with an electric fuel pump.




My supercharger is a SN-93 Paxton, my plans are to use an intercooler and a water injection system.
Running between 6 to 8 psi for the boost.
According to the CR calculator of the Fordmuscle website, my CR is 9.96:1




What are your views on this?

first, any engine can be supercharged. the limiting factor is teh octane rating of the fuel you are going to use. the higher the octane, the higher the compression ratio and/or the higher the boost pressure you can run.

now to specifics;

if your engine is going to be used on the street, i would limit the boost pressure to about 6-8psi, and run at least 91 octane fuel, and limit the timing advance to around 28-30 degrees total. that should keep you out of detonation problems in most driving conditions, though you might have to cut the timing back further if you live in a hot area. one thing you can add is a boost timing retard system that automatically cuts the timing back to prevent detonation as well. again though limit your total timing advance to 30 degrees or less.

for a race engine where you will be running a higher octane fuel, or alcohol, you can run more boost and/or timing as needed, though i would limit boost pressure to 10-12psi and timing to no more than 32 degrees total advance.

He should get away with a little more with the Water/Alk injection. My worry is also with the pistons and crank. I'd definitely stick to your 6-8psi and stay on top of your water/alk bottle. If you tune it for that setup and run out your going to blow a hole in a piston from detonation.

I use 99 octane fuel here in the UK
