Default Intercooler

Can I put an intercooler in a Bonneville and if so, how much HP gain could there potentially be?

You certainly can add an intercooler. Although you wonít necessarily gain more power from it alone. Adding an intercooler often allows one to add more timing or turn up the boost more to gain more power. But looking over your sig you donít have much in the way of mods; so there is plenty of things you can do to much cheaper to gain more power at your current mod level.

Even with a cam and headers & full exhaust on my car Iím not even thinking of a intercooler yet.

Haha well I was just wondering

If you don't mind me asking, how much were those things (cam, headers, exhaust)
Cause, currently, I'm looking to by a whole new exhaust system and I'm a bit foggy on it.

It gets pricy fast...

My whole exhaust system probably cost me $1'600-1'700 or more
Headers - 875 (I installed them)
Mufflers - 250
Tips - 160
Custom bent pipe - 200
Other costs for bolts, gaskets, hardware


I installed the cam myself also which again saved me ton$
Cam - 300
Springs - 135
Timing set - 100
Retainers - 30
Install kit - 130
About $50+ for other bolts, lubes and hardware

Rough total for the cam ~ $750



I think a good starting point for you would be 1 range colder plugs, 180 degree thermostat and a 3.4" or 3.5" supercharger pulley if you are looking for more power.

Well for exhaust I was going to get a catalytic convertor, resonator and mufflers and tips, but I never considered getting headers. I think I will though.

I was already going to buy a PCM, a scanner, a thermostat, etc. Pretty much all the things in the Intense Package 1, except for the FWI.

Actually here'* what I'm going to buy, or consider buying, from now until spring:

Mufflers & tips
Catalytic Convertor
Headers
180 stat
gatorback belt
3.4 or 3.5 pulley (which is better?)
Scanner
Intense PCM

Now granted not all those things add HP, but out of all of that, approximately how much HP gain can I expect?

Depends, it comes down to a matter of scanning. You want to run the pulley that will give you the least amount of KR while 0 degrees of KR is what we all aim for.
