intake question

i just bought a '89 gt a couple weeks ago and im trying to figure out what cold air and intake system i should run. im looking at a bbk performance setup, or a trick flow specialties. :shrug: the motor is stock. any information would be appriciated. which system is better and what kind of horsepower gains would i see?

I would suggest doing a search but you can pretty much end the thread after what I am going to tell ya.

There are no horsepower gains over a stock intake with silencer removed and K&N filter. The only thing you stand to gain from the ones you mentioned are looks with matching performance. Enjoy!:nice:

Edit: There is one intake that is above the others. Its a Strype intake with direct ketchup injection. You can get it from S&B.
 
on a stock motor, there are other bolt-ons that are of a much higher priority than CAI and intake...entire exhaust system being tops on your list IMO...the intake is not the weakest link yet
 
So to clarify you want to put in a cold air and change your intake? I like the JLT cold air or the Anderson powerpipe. As far as intakes I like the trick flow street stuff for a stock set-up or a tubular GT40 would be nice too. What's the plans for the car?

And yes stay away from the Strype intake with direct ketchup injection

well, its going to be a daily driver with occasional track time. my goal is to make it a streetable 12 second car.
 
ok, so who makes the best headers, and should i go with an x or h pipe?
also would a 75mm throttle body do anything?

bbk and bassani are ur most reputable companys for headser i wuld personally use any ceramic coated bbk header and x or h pipe dont matter thats personal choice in which u think sounds better u might gain maybe 1/2 hp to 1 hp with the xpipe so really its more about which sound u prefer

hey, half a horsepower is better then none. can this be done with the motor in the car, or would i need to take it to a shop? im fairly mechanical and dont mind doing the work myself, but if its a major project that requires a lift, i dont have acces to one. any ideas about the 75mm mass air meter? i just bought a k&n first gen. cold air
 
A 75mm t-body is too big for a stock engine.And pointless if you don't have a matching spacer and open the intake to match.You need parts that work together,not just toss parts at the engine.Bigger doesn't always mean better with these parts.

Great advice, listen to it..

Look at the 93 Cobra and the add on items used with it - GT40 heads, Cobra intake, 1.7 rocker arms, cam. All were matched together to make a fast, smooth running street ca that you could take to the strip and get good 1/4 mile times. It not about big this and fancy that, making good streetable power is about matching the components together so that they compliment each other.
 
I preach this all the time, there's almost no such thing as "too big" with the TB (within reason). In a fuel injected car, all the TB does is get out of the air flow's way at WOT. It is NOT like a carburetor, we don't have to worry about maintaining "velocity" to get proper fuel mixing. The only thing you have to worry about when going with a bigger aftermarket TB/EGR, is grinding the the opening in the upper intake to port match. Just slapping a bigger TB onto an untouched, stock intake leaves a big step from the diameter difference that the air will get caught up on and will actually hurt the flow.

Now, I ran a 70mm TB/EGR on a stock intake for years, and I was able to port match it just fine. In fact, I know people who have done the same, and you'll read about how to do it in magazines from time to time. That said, Gearbanger101 (a mod on this site) told me that he once broke through a intake casting trying to port match it. I guess you just have to be careful and be prepared to replace the intake if you end up breaking it.

On that same note, running a bigger aftermarket MAF meter is also a very good idea. The stock unit is so small that it actually chokes a stock engine, let alone a modified one.

Finally, a word on CAI. Back when I was young and dumb, I bought a generic CAI from Summit Racing. If I could do it all over again (which I will at some point), I'd build one from scratch. Buy a couple silicone couplers and some 3"/3.5"/4" exhaust tubing (chrome or paint it, or maybe even use painted PVC), trim it all to fit and viola: you've got a very functional, very custom CAI, and you've probably spent less than you would have on one of those kits.
 
thats why im asking questions. all good input. last time i had a 5.0 it was bone stock, and i couldnt afford to do anything too it. i think my next step is going to be a set of bbk 1 3/4" long tube ceramic headers and an x pipe. that will be a few weeks away since i just had the transmision rebuilt. thanks for all the info guys :hail2:
 
Just my .02 here, but does anyone else think 1 3/4 is a bit big for a completely bone stock 5.0? I truly dont know the answer, but also know I am pushing a fair amount of horse through a 1 5/8 unequal length run of the mill set of headers...:shrug:

Could be like what Nik was saying though and not really matter.. dunno!
