Any mods for a Bonneville 88 SSE?
Talk to Jim W. He had an 89 SE with a Magnaflow muffler (sounds amazing). There are several options if you want an intake. A lot of members are currently looking into making one. I will give directions on one I made a few weeks ago.
And pop a 180 thermostat in as well. There are several performance mods for these engines. You'll find a lot of ideas here! Welcome to BC

why a 180 theromo stat? wants worse gas mileage? that mod is for supercharged cars, so that when they put a smaller pully on and the KR goes up, that helps it go down a little. heat = knock, 180 tstat brings the heat down a little, your car makes its most power and best air fuel ratio when its hot and in closed loop

All cars benefit from a colder intake charge, with no detractant to mileage.

all a 180 t stat will do will make your car take longer to get into closed loop, more time in open loop more gas (runs rich in open loop).
yep, cold air is more dense, more air = more power. but that 180 t stat will drop underhood temps by, maybe 10* tops, not very much, that in combination with the tiny amount of time that the air spends in your engine bay before going into the TB and then combusting ( maybe 2 seconds ) that air going into the combustion chamber is now, what? 1/6 of a degree cooler? .2hp? .3hp? thats being generous
I'm with Don. No 180 stat will make a mileage difference (unless there'* a contribuitng factor....something else wrong), and may increase the life expectancy of the drivetrain and it'* components.
