My car will start to misfire at WOT at higher speeds...around 60 i believe. Was wondering if I should change the plugs or is it some thing else. I just bought the car about 2 weeks ago so I'm not sure how old they are but the guy took very good of the car.

Here is a link to the car and its list of mods.

Also if possible could someone give me a estamated HP and torque with these mod including a cone filter.

Thanx in advnace:)
 
Wire situation....

You'll definatly want to look into your plugs and wires. If new plugs and wires don't solve the misfiring problem, then other ignition diagnositics should be looked at, but usually a misfiring problem is due to eaten plugs and wires.

You've got a few of the mods done to your car, figure that the

Free Flowing exhaust is worth=15hp
S-model Supercharger (I assume a 94-95) =30hp
10% O.D pulley =15hp
K+N panel filter =1hp
Removed air silencer =4hp

I could be off on some of the numbers, but based on what other's have reported those mods can do for the engine, your definatlly looking at about 60-70 more HP than stock.
 
you might want to check your coil pack, changed all my plugs twice and bought 2 sets of wires before I noticed a tiny crack at the bottom of the coil pack
