I was wondering if a front mount intercooler is possible on a 1990 sc? If so what brand and dimensions should I look for?
And have you guys noticed any thing different in performance? Also as far as the length of the project is this a day project or a weekend kind of thing?
here's my example. cheap and alot less piping to run than the other examples.

So a ported 94 blower with a 10% only gets 15-16 pounds? Seems to me like you should be running more than that.

well thats a guess-timate cuz it pegs the stock gauge and im sure it will push a lil more.
thinking of putting my autometer gauge in to see what it really is.
i think its about right cuz stock they push 11-12 and porting causes a loss in total psi and then add 10% od.
Ok, I didnt know porting causes a loss on psi, what does it help then? Air flow?

You need to remember that boost is an actual measure of back pressure, not the amount of air going into the motor.
An example would be taking a ported '94 blower OD'd at 15% that is registering 20 psi into a motor with stock heads, stock cam, and stock exhaust. Now take that same blower on a motor with fully ported heads, big cam and a big arse exhaust and it'll only register 13psi, and make a crap load more power because more air is actually getting into the motor to be used. This is what you want to see happen.
The guys that are pushing 25psi.... if they could use the same setup but only see 15psi would make way more power because there is more air freely flowing through the motor, but alas, we don't have the head options that will allow for that .
