Default 1993 ssei

I was just wondering how much hp my ssei bonneville has without adding a a 80 series flowmaster muffler and a Cold air intake system(K&N X stream air filter) and a new supercharger pully and a drilled 180 thermastat.

And roughly how much hp it has after adding those

I'd say your sitting around ~190 FWHP, so you made back your drivetrain loss (~20%).

Stock for a 93 is 205hp, 260tq. With the pulley, intake, and exhaust, count on 230-235hp. The intake and exhaust only support the pulley change, and don't add much by themselves.

Remember that even though you would be approaching the Series 2 hp/tq spec, your peak delivery is at a much lower rpm. The S2 would out-distance you on the top end.

If you don't have a scantool or fuel pressure gauge, a 2.3" pulley would be the safest smaller size to go to. If your fuel pressure is good (at least factory spec) and you have a scantool to scan for KR, go for the 2.2" pulley. But be advised that if you get KR with the 2.2", you'll have more work to do ($$$).

190 (FWHP) x .20 (Drivetrain loss) = 228 (HP) right on with Willwren'* 230-235 HP.
