I'm planning to do a few things to my car since my job cut my hours and school has not started yet.How much more horsepower APX will this add:

Removal of AC Compressor
Adding Underdrive Crank and Alternator Pulleys
Adding a Magnaflow High Flow Cat
Throttle Body Coolant Bypass

Im guessing around 15 HP all togather from the underdriving,extra exhaust flow and weight removal.

 

don't bother with the alternator under drive pulley, you will run into charging issues

 

Yeah , I was thinking about that but I dont have any big energy draining stereo system or anything.Just a cassette player.I dont even use my fog lights.

 

Hate to burst your bubble, but I don't see fifteen horsepower at the rear wheels there.

3-5 at the most.

Removing the AC compressor didn't add any power, it took away 15-20lbs, but when the clutch isn't engaged it doesn't use any power.

The Magnaflow cat may flow more than the stocker, but the real restriction is in the manifolds and "Y" pipe that preceede it.

I'm not tying to be hatin' on ya, and I know you want to make some more power, but don't get overly optimistic about it.

 

even though you don't have anything major putting starin on the alternator, you will still run into problems. the gain vs the risk is not worth the price for the pulley

 

Actully on that show on Hist Channel "Full Throttle" , 68 Mustang version that dude said an AC compressor takes 4-6 HP just to drive it with the belt when its not engaged.

 

It can't possibly take 4-6 hp to turn it. Take the belt off and turn it by hand; it spins effortlessly.
Also, I just put a high flow cat on my car and it made no difference in power. It does sound better though

 

Hmm 3-5 HP most is pretty weak considering that like over $100 worth of mods.

 

That's how it works. If you'd ratehr spend the money for power, I'd suggest a cam swap (about 200 bux if you do yourself), or Nitrous (about 500 bux). Outside of port work and custom type stuff, there isn't much you can do to these cars to make a decent amount of power for under 100 bux.

 

I second that F-Bod.

V8 Slayer, we're not here to try and discourage you from modding your car, but a lot of us have "been there, done that" and learned form our own mistakes as to what works and what doesn't.

Keep in mind everything you hear on TV and in the Mc Donald's parking lot ain't always true, and we'll help you sort out the monkey spank from the fact

If you want noticeable power out of one of these, look at some of AIM91's mods- he put a LOT of effort into porting the heads, combined with boosting the compression and a good set of headers. Then he combined it with a converter matched to the engine's powerband and 3.73 gears.

 

Does fabricating your own turbo system count as custom type stuff? I'm hovering around a $110 investment currently if I count some of the flex exhaust I'm using to finally pipe the exhaust OUT of the engine bay...

(On the other hand, the setup basically put the nails in my old 2.8's coffin... that's gonna cost more than $100 to rectify.)

 

Maybe it takes power becasue its an old stly compressor and they did something different then the newer free spinning ones

 

I was wondering what was going on with your setup. I still have my old 2.8, If I blow this 3.4 up with too much juice, I'll either go back with a set of forged pistons and a rebuild, or build that 2.8 for turbo and put it back in and sell the 3.4 stuff. Doesn't seem like this 3.4 will die though (knock on wood). We'll see how it does on the 22nd, FINALLY gonna get track times with juice

 

Status report is pretty simple.. I'd rather drop in a 3.4 than go about giving the small journal 2.8 new bearings and valve seals .... absolutely no faith in that motor.

 

weight reduction & suspension. make the most of what power you have, then decide on what other combo of mods in the order that you cain afford shoudl come next.
