    Best modifications you can do are porting the supercharger, using some type of intercooler whether it's a Double Intercooler or a front mount, catless exhaust, ported heads and a cam, a converter, and 3.73 gears.

    Everything else is very minimal gains.

    Browse around a few performance sites:

    I guess ill pick up a set of high flow 2.5 cats and a 3 dynomax ultraflow mufflers 1 duel in duel out and 2 singles and bend up a exhaust on my bend pack this weekend . Maybe that will give me something.

    Some strange combinations you have. A 3.5 fresh air intake, 76MM maf, I assume a stock throttle body. Not very well matched. Porting the blower wont do you much good pulling air through a stock plenum and TB. The 10% will generate way to much heat and pull the timing on the top end even with a fan on the IC. The exhaust will do you a world of good and you should feel an improvement. The 180 degree thermostat wont do a lot of good unless you program the fan to come on sooner. You need a chip in the computer for that. The top will get you little to none improvement untill you get to a much higher level of HP.

    1 Exhaust
    2 Bigger TB and plenum
    3 Better IC with that 10% over drive
    4 SCT chip and tune

    These are the basics. If you want the biggest bang for the bucks

    1 An autorotor, if you can find one
    2 Cam and heads

    All kinds of bolt ons wont do what the cam and heads will do for you

    For bolt ons you can go Magnum Powers inlet for SC and at least a 75mm TB. The S port charger or MPII would be a greaqt upgrade if you can find one...Or hav eyour charger ported

    The exhaust is definitely a restriction. The cat section and resonator have got to go.

    A nice tune will wake it up as well. Unsure what your best fuel pressure should be but that can throw things way off. Someone here will chime in for sure. You can do tweaking with the fuel pressure. 42lb lightning injectors can be had cheap and if going for a tune a good idea at this point..There will also come a tim ethat the 190lph pump will not do

    A nice converter 2400 stall and thw 94-95 autos have no trac loc..Youll want to get that>>>if you have a shop a nice gear swap would do wonders. 3.73 are good track gears with 4.10'a beig ideal IMO

    after all this..When you arent 100 % happy...A good head and cam package will make all teh difference

    a 85mm throttlebody and a mp plenum are on the horizon. Just doing this slowly this is my beater car to get back and forth to work with. I spent to much cash on my vette this month so the beater will have to wait for some more mods. I currently have one of the fastest C6Z06's in the country. All motor 10.51@132 nitrous 9.94 138. built 100% by me. Currently the car has a 25.5 sfi certified cage good to 7.50 et and building a new 445ci nitrous motor to make over 1000 rwhp.

    if thats the case then no need for an 85mm. 75mm will flow plenty.

    George,

    You have a dyno. DO you also do tuning? If not I may have someone for you.

    Let me know

    The 75MM is a perfect fit for a 3" intake tube but since you have a 3.5" tube and your going to up grade, get the big TB so you are matched.

    ahh, forgot about that. well for a 3" intake and 76 MAF and 75 TB match up perfectly.
