Boost on my 5.0

so i want to boost my 90 5.0 mustang without doing internals how much boost can i run? i heard i can go like 6-8 pounds on stock internals. and whats the cheapest way i can get a super charger or turbo that i just push those small boost numbers. thank you for any info

It depends on what condition the stock motor is in and what you consider "cheap".

Personally, if it's street car, I'd only go with a system with some type of charge-cooling. That would trim down your options to a centrifugal type supercharger or turbo.

Turbos make crazy torque on a 5.0, but installation is more complicated, and kits are more expensive.

Centrifugal superchargers make good HP, but boost with RPM. The hardest thing on stock internals is over-revving them.

Stock engines are "safe" up to 6 lbs of boost, maybe 8 lbs...if you are careful, use a good ingniton retard and always use permium gas, the higher octane the better.

The downside is the stock block startes to self-destruct when it gets in the 450-500 hp zone. You will start to run into head gasket failures, then getting enough fuel to keep up with the engine, then oil pressure becomes erratic.

Finally...boost is addictive. No matter what you say, now - sooner or later you will want to crank up the boost...just a little. a good after market super charger kit will deliver an easy, safe 50% hp boost at 5 - 6 lbs. At 10 - 12 lbs, it will double the factory rating. At that point heat, intercoolng, detonation and common sense will become your main issues.

one thing you need to remember its all in the tune
