Intake
Ok guys and gals. Please excuse my ignorance on this. I have a stock 89 gt vert, ecxept for a flowmaster catback. What are the advantages of a new Intake(example gt40)? How much hp will I gain from this ?
Thanx in advance. Bill |
there are a lot of things you can do before an intake will help you out...check my sig, there's a link to my webpage...you might find it useful

I agree with Stock865.0 ....BUT....if you really wanna switch out the intake, doing so would give you gains. About 10-15 hp on a stock head 5.0. If your not planning on changing out the heads anytime soon, a very inexpensive (way way less then an aftermarket intake), and viable alternative is to go with a stock ported lower intake. On a stock head 5.0, a ported lower will give you the same gains as an aftermarket intake. PM me if your interested in a stock ported lower intake.
Word to the wise, if heads are in your very near future, spend the money on an aftermarket unit straight out. |
I guess, we need to know what you want this car to do first...
Let us know your plans and our advice becomes much better... |
I'm just looking at ways to make it a little quicker. I really dont't race the car but I'd like the power to be there if I need it. I'm planning on advancing the timing this week end.

How long have you have you had that pricey flowmaster cat back (that is actually slowing you down)?
I say sell it to a nother mustang guy who wants the loud barky 5.0 with nice tips...use the the money to buy two Magnaflow (straight through design) yet extremely quite, some turn downs, and some stainless or even stock replacement flow tubes, and you can then bolt all that up yourself....save weight, runs quiter (a little noiser in the car...but do you really mind to be FASTER than them other guys????) How much are you planning on advancing the timing? Don't forget, the more you advance the timing the higher the octane you'll need to prevent detonation. |

that new bbk looks sweet and it delivers good power :tup

Spend the money on an aftermarket intake. Try to stick with the same manufacturer. ie- Edelbrock intake, heads. Trick FLow Intake, heads. Holly Systemax intake, heads.
It does depend on where you want this car to end up and how far you are willing to go and what budget you have. Be prepared for a surging idle and or hesitation when you begin to mix and match your setup. I would not suggest porting your lower because your heads are still stock and will not match up. Some guys used to take a old f-150 lower and port it. Technology has come to far for you to ignore it. I like the Edelbrock because you can gain easy access to the inner flow of the upper due to the removable end cap. Just my 2Cents. |

NOW with that said, the stock intake is no match to an after market intake once heads and cams start going in. When compared to street intakes, the runners are just to long, and the plenum volume to small to support big gains over 4800 rpm. But please don't start jabbering about stock intakes, when you don't have all the facts. NOT everyone with a mustang stuffs the engine bays with a bazzilion dollars worth of aftermarket goodies......most remain pretty stock. |
Why you getting so Jumpy? Lol. Seriously dude I was just offering my opinion, just because it does not match up with yours does not mean you need to rip it. Sorry I did not type for hours and go into detail. In no way was I ripping you either so read my post again. I will tell you one thing, paying for someone to port a stock lower is a waste of time and money. If you can do the work yourself then fine. But if he is going to pay for someone ...ie yourself to port a stock lower he might as well buy an aftermarket piece. Secondly, when you begin to change parts without tuning you run into issues with driveability. I guess I forgot to say tuning last post. I would rather do all my mods at once and spend a few hours at a reputable dyno facility to ensure all was well. Maybe my attitude in this area is one reason my car was always ready to run unlike most fools in woodbridge who hung out all night for the coffee.
Lastly, my car ran 11.16 with stock heads, stock intake, street tire at Cayuga once, I too know how to go fast with stock parts. Give or take some spray..... :chacha: Next time, try to remember we all have opinions, and we are here to share them with each other. :cheers: |
opinions are fair....I never fault someone if theres is different then mine. But the facts should be right. Scaring someone off on idea with false facts is not right. Not just for the person posting, but everyone else reading to learn. I'm a stickler for that sort of stuff..... sorry for the 'tude.
As for pricing, yes I do port stock lowers, but I will tell you this, I do a very complete job, but my pricing is a fraction of the cost of an aftermarket intake.......I don't post pricing, but lets just say it is "fair market value" Edit: Oh ya forgot to say...good one on the name thing (touche), thats actually pretty funny ....lol |
you want to learn a little something about the potential of the stock intake take a look at Tmoss' site at http://www.tmossporting.com/Home.aspx
just for anyone that is interested. there's lots of tech, flow, dyno, and testemonial info there.... |

I'm not new to this game and I disagree with your opinion StangSeller. Having said that you are entitled to your opinion as am I.
Do you know how many Mass Air units that allegedly come calibrated for a certain injector are a waste of time? I guess you have been lucky in your experiences. I have worked on 9 sec street cars that ran great as well, but only after they were fiddled with for a bit. By adding mods and not dyno tuning you are risking possible failures. You are also cheating yourself out of the hard earned dollars that these mods and their performance gains could offer you. This cannot be debated. Why else would professional race teams spend millions of dollars, miles, and hours testing new components? |
Hmmmm just noticed a guy was having issues after installing a exhaust system on his 85 GT. His idle is different and the car chugs on the highway. Please see his thread in the 5.0 tech category and offer him any advice you might have. It should have just bolted on with no driveability issues, shouldn't it have. I don't know, I must be an annoying newbie and an enormous smart ass. :biggrin:

While we are on the topic of intakes and surging, I have a problem with mine.
Everytime I push the gas pedal down and up, the engine rpm surges up and down. Will putting a ported and polished shifter ball help this problem? Or do I need to port match my lower stick to help the carburetor choke open sooner? thanks in advance O/S :cheers: |

I think a long winter has made us all go crazy! I guess if we didn't have to look at our prized Mustangs in the garage for 6 months of the year we would not suffer like we do.

I offered my opinion and you jumped on it so I offered some sarcastic remark. It was a joke. Dude have a sense of humour!!! You are taking yourself far too seriously.
That being said, we actually know each other and this would not be an issue if my identity were revealed. Nuff said. :cheers: |
By the way I was modding my Mustang before you were allowed to drive. :tup

I'm not sure if my last comment was ripping you or the reason why I can't get out of bed in the morning. :banghead:
