A simple question.

[_Aramchek_]

How much HP (estimate) can be made doing the little simple and relatively cheap things before I'd have to start really getting in to spending a lot of time and money on my 91 SS?

[Aerotech]

Intercooler ($150)
Manual Boost Controller ($50-70)
Boost Gauge ($60-100)

You can have a hell of a lot of fun with just these 3 items. Turn up the boost to 11 psi or so, you'll be amazed. Probably around 180-190 HP.

Note: You MUST have all 3, or you'll damage the motor...

A $300 ebay exhaust can go a long ways too
