Basically what I'm looking for is, who's has the most Horse power out of thier 2.8L Fiero with the use of a supercharger and or Turbo? As a few of you know I have been working on a 86 Fiero GT from Michigan that has a rebuilt 2.8L with some minor internal mods and it has a RSM superchager kit. WOW I said "RSM" 
When this car was brought to me, the owner Curtis York and his father Barth York had said to me they have been trying for years to get this car working right. First thing first I installed a boost gauge, Mr. York said to me when the charger was installed the car would put out 8 psi. of boost. Well once the gauge was installed I say at best 3 psi. First problem. Second I took a look at what was used for programming, well not much again. So after a few months I have installed a water to air intercooler, reprogrammed computer, installed knock sensor and modual, 2 bar map sensor, custom cranck pulley, custom blower pulley and idler, injectors and so on I got..... 235 Whp and 291 Torque...... now the car hits 11 psi...

So all I want to know is who out if Fiero land has the highest horse power 2.8L Fiero? Looking forward in for your replies.

Thanks
Joe

Sounds like a commercial for the Fiero shop, point here is that if horse power is desired it is a waste of time and money to retain the original 2.8l engine. Dan

Joe I could be wrong, but I don't think you'll find any significantly modified 2.8's here.  Most who have them are either maintaining them in near-OEM configuration, or chucking them in favor of something newer.

That makes for a nice upgrade.  What did you do to that motor to make so much power on 11 psi?  By my calculation you shouldn't be able to make more than 215 whp without other major mods.
