hey guys, ive been working my 87 Mustang for a while now but i was wondering what else i could to to the engine to gain some performance and HP that i havent already done. So far my engine mods are...

1-Trick Flow Upper and Lower intake
2-Roush heads
3-Adjustable fuel regulators (and 190 LPH intake pump)
4-24lbs injectors
5-Fuel Rails
6-Throttle body (the guy said 75mm, but at least 70mm)
7-Underdrive pullies
8-Air intake ( not sure if its aftermarket or stock, it has the chip on it like it but im not sure, anyone know? )
9-E.L. headers, look like crap but do the job.
10-MSD 6AL and ignition system
11-Accel Spark plugs and wires
12-(if it matters) H-Pipe and Mac Cat back Exhaust
13 new Rad with dual Fans

Thats about all i can think of at the moment But is there anything else i can do to the engine get some HP ? (except S/C or Nitrous, thinking about it ) But first i wanted to know if i can do anything else, like maybe get new heads, i dunno how good these heads are, or what to compare them too, most people dunno what they are. Or would a fender well CAI help? And is this one aftermarket or no, im not sure anymore,lol.

But yeah let me know what ya think and suggestions are helpful, thanks guys!
Also heres a few pics of the engine, incase i forgot something ya might be able to see it....

Bigger MAF?

[The Novice]

Well i bought the car with most of this stuff on is, is there an easy way to tell how big the one i have now is? And would a bigger MAF really increase HP a lot?

So i guess i could do a Fender well CAI, ill have to move the MSD box though, but what CAI do you guys like? Btw is fenderwell really better And adds more HP than the non fender well? b/c i would imagine that the engine is sucking in so much air does in the engine bay and heat rises and as your going 70 MPH down the road and air is constantly being blown through does fenderwell kind really make it that much better and add more HP? Sorry just wondering.

Also BBK had an ad once for a CAI kit, ans it said 10-14 HP to the wheels, is that B.S? How much HP do ya think i could get outta a good CAI kit? Sorry for all the questions, but i really appriciate the help!

Also any other ideas? Thanks guys! - The Novice.

I call bullshit on the numbers, but its a def improvement, i have a MAC and its the exact same as a bbk i had on my last car, same quality, i dont think its worth 150 bucks id just wait till one pops up on craigslist, thats what i did

So the K&N BS too, they say the yare the best and that they filter more and all that junk, is it any better than anyone else, or just get anything? But Def. Fenderwell though? Also am i pritty much shit out of luck wit any other mods? i cant think of anything else i can do....i was enjoying putting new things on my car

my guess they are Roush 200 heads. those are pretty decent heads. you might be able to get more out of them at the machine shop.

So ya thinking maybe a lil port an polish action? I always wonderd how big can you port heads, like i dunno, does porting increase your HP a lot, very little or is it more just help the fuel go threw faster?

[stangfreak]

i've seen posts saying they flow more than afr 165s and posts saying less but so far none of these chuckle heads provide any flow numbers to back it up.

Have you done gears yet ?
3.73 gears vs. stock is like a whole new car for $500

depends on the head. i plan to make 550hp on stock cast iron D3VE heads

[stangfreak]

here's an interesting quote concerning Roush 200 heads

"i have ported most the diffrent heads out there and have ran quit a few myself.the world product heads respond well to porting(so should the roush very similar).i ported a set and didnt remove to much material and they went from flowing a max of 234 on the intake and 141 on the exhaust,after ported they were 286 on the intake and 201 on the exhaust and they picked up everywhere even at .300 they were already up over 30cfm from before.these heads seem to work well on a carbed combo but not always well on a fuel injected combo.havent figured that one out yet.

BUT..if you dont like porting heads get something else these are terrible heads just to bolt on."

Well that sucks,lol. I dont have a Carb. and the yare crap stock, Do you think i should port them or get new ones. if the guy said they are more for carb than EFI? Also would i need to go to a porter who knows these particular heads, or should he know what he's doing? Also, got a guess on price? B/c i think ill have to deside if i should port or just get new ones depending on how much this porting thing will cost. Thanks again for your help guys!!

maybe sell them and put the money towards something like AFR 185s?

Do you know if thats the stock MAF? it looks like it to me. I'm wondering how you are running 24#ers with the stock MAF (if thats the case), unless the previous owner had a chip burnt or you're running a Cobra computer. If thats the stock MAF with no changes made to the computer and you're running those injectors, then yes, you should notice a nice increase if you get a bigger MAF cal'd to the 24's.

Well forgive me if im wrong, but its an 87 so it had speed density, and the previous owner did the MAF conversion, So wasnt there no MAF on the 87's so it would have to be aftermarket correct? But is there a way i can find the exact size of the MAF? Also while im at it how can i know by looking at the injectors if they are really 24lbs or not? Also just to make sure im looking at the correct thing, the MAF is by the throttle body right?

How much do ya think i could get for them, i dunno how much they were new and they havent been on there for more than 10K (supposedly, previous owner.)

Also AFR 185's eh? those wont be too big for my 5.0? Would ya say those or Trick Flow's? i hear those are good too, but are AFR's better?

again guys thanks for the help, very much appriciated!
