Next Step: Headers or MAF

Daniel50 · Jun 27, 2005

cant decide which to do next. My mods are in my signature. what would i benefit most from here? Ford Racing Unequals or a 75mm pro m mass air meter?

90mustangGT · Jun 27, 2005

MAF,

Until you get heads, headers arn't going to be worth it.

Michael Yount · Jun 27, 2005

....and I doubt if the stock maf is holding you back. I'd replace or have tmoss port that stock lower intake - that's the biggest restriction you have on the (mostly) stock engine right now.

BaXTeR3221 · Jun 27, 2005

I agree with michael, you'll get the most out of an intake change, whether you have tmoss port the lower, or if you just buy a new upper/lower set-up.

N8Miller · Jun 27, 2005

I would do a cobra intake. actully, i would get a performer because i like the edelbrock products.

OT: baxter, did you get your kit? i lost your AOL IM name.

tmoss · Jun 27, 2005

If your not going to change out heads, a ported lower is a cheaper way to make power. If you will be changing heads, the Cobra/Explorer is a good choice as is a used Performer.

stock maf , intake and tb is good for lows 12's....will support 300 hp

if you use your nitrous a lot you will definitely benefit from headers...go 1 5/8" long tube

if you don't use a lot of nitrous .... save your money for now , for heads

don't do an intake til you get heads, that is THE biggest waste of time and money known to a 5.0....even though 100 people will tell you do so.

it isn't worth 7 hp on a stock headed car.

i know this from experience, i did a gt-40 w/ ported lower and the car ran the same as b4.

i only put it on cuz i had it (and gt-40's look awesome) but doesn't do squat.

Actually, anyone who has put a ported stock lower, or a WELL MATCHED aftermarket intake (GT40, Cobra, Performer, etc.) on a stock headed car will pick up an easy 3-4 mph in their 1/4 mile trap speeds.

Sorry you made the uninformed decision to put a ported GT40 intake on a stock headed car. There again, not knowing the extent of the porting, or the condition of your engine, I can't really comment on what you did, but an intake is certainly not a waste of time by any means. Best bang for the buck on a stock headed motor besides gears.

NKau · Jun 27, 2005

Back to the original post, I would go with what most everyone else said and get an intake instead of spending money on headers/maf/tb; none of which are really neccessary for a while. An intake will give you a noticable power gain at higher rpms, and will still be there when you are ready to put heads on.

5spd GT · Jun 27, 2005

A ported lower sounds like a good idea.

Your not going to gain an "easy 3-4mph" with just an intake swap. That simply isn't going to happen.

Lyncher · Jun 27, 2005

get a nice intake like a performer or cobra..then save for heads!! Once you get the heads it will make the intake much more effective as well as the headers if you get em!

Yep, should have sent you message when i got it. Everything was there and it looks good, thanx

Daniel50 · Jun 28, 2005

well an intake is possible. since i dont wanna swap heads or cam. intake, s-trim, maf, headers, and injectors is what i got left for performance on this car.

tmoss · Jun 28, 2005

I'll let an email from a ported lower stock intake say it.........4 tenths is doable if you have the rest of the combo right..........

Hi Tom.
I got some new times for you. Run the car yesterday. I run new best.
13.64@100.17, 13.66@99.83, 13.54@100.6,13.55@99.6, 13.56@101.3
- I improved .46 tenths & gained 4 mph. But I know there's more in it. Do you have any idea what can help me. The only other mod i added with your ported stock lower was a 65Tb. The car really lights them up on the street. Also I had a cooling problem it kept running hot I give it a good cooldown but the water wasn't running right so I think I will get you new times next week (added above later). My radiator busted and ended my night early fan clutch give out and the blades broke thru.

Thanks bud
Frank

I like the idea of an intake as well. Do you have the rest of the exhaust (besides headers) already done? If not, I would do that before trying to put more air through the motor.

Flavadave4 · Jun 28, 2005

i agree to port the lower or a cobra/GT40.
the headers arnt really going to do alot for you with stock heads and intake!

Figured I'd post that just in case you missed it Dave

I didn't miss it

Was the variables the same? I gained 3mph from one track trip to another with no changes whatsoever. Just drove it different. So think an intake change would give me 7mph

3-4mph is the equivalent of a broad "torque curve" of 30-40hp roughly. So I ask you, from an intake?

Edit: Oh and I was talking about a stock engine (as in this case).

I'm talking about a car running consitent 96 mph traps running consitent 99 mph traps after an intake swap.

A better intake gives you 15+ hp with stock heads (I think we can agree there). I picked up 3 mph with nothing but a performer intake with what are to the best of my knowledge stock heads. Trapped consistent 96.x's with the stocker, and consistent 99.x's with the performer. The numbers may not make sense, but they are what they are. My sig should be updated, but I'm waiting until the heads go on.

So would that be 96.9mph to 99.0 mph? That would be 2.1mph...see where I'm going with that. (not 3-4mph) I just like to be more specific
