Ballpark Hp

[beej1990]

was just wondering if i could get some opinions on what i might have hp wise and what it might run in good conditions...also if i need a tune or not ive been told my car won't be able to get tuned cause of how old it is or something to do with the computer not exactly sure what they were talking about i thought it could get tuned just fine..i have no idea about tuning so idk

its a 1989 fox body, 5speed

the stuff thats done to my car:

its been bored to 306
gt40 tubular upper intake,cobra lower
24lb injectors
70mm throttle body
shorty headers into xpipe
edelbrock performer aluminum heads
trick flow stage 2 cam
king cobra clutch
3.73 gears

i know wanting to know hp and what it might run just by reading a little mod list is asking a lot i know it depends on a lot of different things i was just curious if anyone could just give me what they thought it might be..like i said im aware its just going to be a ballpark guess...and if anyone has info on tuning if it would help me or not or if it can even be tuned.

i would appreciate any feed back thanks

Several close combinations in the thread Noobz linked you to. Definitely get a wideband on it so you can make sure it's getting the fuel it needs.

Ok thanks

you did not list it, so, it probably wants a fuel pump.
yes it can be tuned, SCT comes to mind, and several others... there are also other online types, Bama comes to mind...
power guess, if it's in good tune and still making good cylinder pressure... 300ish hp/320ish tq (assuming you put a fuel pump in it)

I'm saying 270ish at the rear

Comparing your setup to others similar can help estimate the hp but to what end? If you want to know put it on a dyno, keep in mind you could be very disappointed.
Here is my nickels worth of free advice: do a systems check, fuel pressure, vacuum lines, plugs, wires and filters. Check for codes. If it acts up when you 'get on it' somethings amiss.
When you think you got it running at its best then put it on a dyno if you need to know the hp. A dyno will also expose other weaknesses.
It wouldn't suprise me if your combo would make 290-310 hp but I don't know the condition of the car or the engine.
