Hello, I have a 93 LX 5.0 with 125k on the motor. I currently have the following modifications:
-Vortech V-1 Supercharger w/9lb pulley
-Anderson FMS Power Pipe that goes into fenderwell
-80mm Mass air meter
-38lb Lucas Injectors
-255lph fuel pump
-NO FMU
-Edlebrock Performer RPM II Upper and Lower intake (ported)
-Stock heads - non ported
-65mm T/B
-BBK Headers, H-Pipe (No Cats) and mufflers
-Cobra Under-drive water pump pulley
-A/C delete
-200amp alternator
I know that is a lot of miles on the engine but it still runs great! I have yet to get it tuned and its currently at 16degrees timing. I have run it hard and have heard no detonation or pinging. I realize that is a lot of timing, so I rarely go past 4000rpm's.
I want to switch over to a 12lb pulley but I am wondering if that is way too much for it to handle. Probably, but I just want to be sure. I am planning on getting it dyno tuned this month, but dont have any clue what my A/F ratio is or how much boost I have. If I get it dyno tuned, I want to keep my setup and not switch pulleys afterwards.
Any clue how much HP I have? Is the 9lb perfect for this setup or can I go higher still? Dont want to blow the engine but my guess is it wont last that long if I up the boost...
PS- The car ran way better without the FMU
