If your not changing the heads or cam. I wouldn't worry about changing the injectors. No matter how much bigger you make the T/B or the intake you still have the restriction of the heads and the cam.

Idon't know where the TB thing came from,I don't thinkIever mentioned chaging that, anyway. VFAST, the ultimate goal is between300-325hp.I currently have: bbk shorties, 2.5" off road x (i only have 2 weeks tillIwinter parking the car so i'll finish the exhaust in spring, manaflows and 2.5" tails), WMS velocity tube w/ k&amp;n. Also besides the lightening maf you mentioned allI could find were the pro-m's for the 94-95's.Where doI get this chip you speak of? Anyone know of any other maffor the 94-95 cars?</P>


anyway this is kinda my plan:</P>


current mods+, cam, ?maf &amp; 24# injectors?, intake &amp; heads in that order. The heads will be last andI haven't determinedwhat brands asof yet for anything. Opinions welcome! I can teel youI want areliable street car with occasional trips to the track, seeing its only about 5 minutes from my place there is no excuse to not go.</P>


I'm not sure if this combo will net 300hp or not butI figured it would be close.</P>

C&amp;L also makes a MAF. </P>


If you eventually plan on running different heads and cam then I would go ahead and switch to #24's. If you have them on a stock motor it won't hurt it as long as you have the proper MAF for it. The computer has all the A/F tables to maintain the correct A/F. </P>


As for heads....that's a matter of a lot of opinions and what you eventually want the car to run (how much your willing to spend). AFR, TFS, WP, Ford, Edelbrock, etc. all make heads that will get you to your current goal of 300-325.</P>

Now that you mention it I remember seeing the C&amp;L.</P>


Yeah I think i'll just upgrade to a 24# systemso I don't have to kick my own a$$ later.</P>

mmmmmm did I **** MD off?

Ok here's what I've got:
306 block (factory bored .030)
forged rebuild, 8.5:1 cr
Edelbrock performer heads, throttle body (70mm iirc, perhaps 75? yeesh, I don't remember)
professional products power + intake manifold u/l, egr
FMS 30lb injectors (more on that later)
FMS F303 cam
FMS MAF (75mm?)
MAC CAI
MAC shorty equal length
MAC o/r H pipe
flowmaster 40's
adjustible fuel pressure regulator
and for the rest of the drivetrain
some sort of reman'd T5
3.08 gears &gt;I THINK&lt;
17x9 Cobra R replicas w/245/45r17


That combo, with ~1000-1200 miles on the engine, made 260 rwhp and 284 rwtq shutting down at 5000 rpm. The F303 makes peak power at 6000 rpm, so I don't know what the true max output of the engine is yet. Since then I've bought the Tweecer RT and I'm trying to tune the thing so that it'll make decent power.
260/284 translates into about 300-310 crank hp and 325-340 ft-lbs (depending on which number you like to multiply by)

The reason for the larger injectors and low compression is that I had intended to build the motor for a future supercharger. Now I wish I had gone with 24lb injectors and 10:1 compression and just left good enough alone. With higher compression and more efficient metering of the fuel it's probable that the engine would make closer to 400 hp.

You could probably see 325hp with the intake, exhaust, and heads, using the stock cam.

The head test I saw showed that the AFR 165cc head was the best of the bunch (for a street head), followed closely by Edelbrock's Performer.

Stepping up to the 185 and other street/strip heads you lose a bit of your bottom end, iirc (Not worth it on a daily driver in my book).

Carcraft gained 100hp on a 5.0 by putting AFR 165 heads, 1.7:1 roller rockers, and some sort of 4 barrel intake on it.
Fuel injection is more expensive to make run properly, but the total potential is greater IF you can tune it.

Thks for the info. This should prove useful in my quest!</P>

No I just noticed it. I know what an FMU does, but I didnt know how it worked *oops shouldnt have opened my mouth* I thought it increased voltage to the pump to put out more fuel pressure. I am retarted, you got me, wont happen again <IMG src=smileys/smiley2.gif border="0"></P>


Thanks for the lesson <IMG src=smileys/smiley19.gif border="0"></P>

naw wasn't calling you out..just for someone in the market for a supercharge would have read up on it..If I were you I would buy the supercharging hand book just remember you can never learn too much..hope the book helps.. you can sned more juice to the pump for more fuel pressure

horatio...you might want to try a set of 24 injectors as well as a 65mm throttle body ..If you have a 75 it's not helping...
