Upper intake manifold on APOC

Yo guys,
On the American Performance of Colorado website it has a Upper intake manifold that is port and polished. It says something about its made for the 62 mm throttle body. Is that the stock throttle body? or an upgrade i have to get also?

Someone please let me know?

62mm is an upgrade.

Thats crap they make u get a bigger tb to buy their intake manifold ... lol

damn money hogs

Not really...besides it'd be pointless just to buy the mani without enlarging your TB. Airflow is only as efficient as your smallest constriction.

I also suggest getting the lower too. While you in there, miuns well go the whole nine

Why would you get a bigger intake manifold without getting a throttle body. People should understand the upgrades and how they work before they buy them.

If you upgrade your intake manifold without upgrading your throttle body, how is the new intake manny going to increase air flow any more then stock, if anything it would probably decrease velocity. You need a bigger valve to let air into the intake manifold to actually make it any useful. Same as for upgrading your manifolds and throttle bodys without buying a less restrictive intake. Air doesn't just appear out of no where. There has to be a massive air flow coming from the beginning, air isn't just made during the process.

Does that help at all?

And they always tell you to upgrade intake in conjunction with exhaust. That is why many first go with a cai and cat-back, although the SLP cat-back exhaust may be a little too big for the average alero tuner, it still helps. Getting rid of restrictive flowing devices helps incredibly, until you do it to the point of no or little velocity.

my quote thing isn't workin so i'm gonna just manually do it:

:rolleyes: This is true and also the reason why getting larger diameter exhaust pipe AFTER the cat is basically pointless (or at least NOT worh the $$). Your cat is 2" inlet/outlet and ur factory "headers" are small too, the only way ur gonna gain some good HP is if you replace ur headers, cat, AND ur whole exhaust piping.

First of all, their prices are pretty reasonable. No name to toss out insults at our sponsors. You don't HAVE to buy a ported TB if you don't want to... just like you don't HAVE to get a CAI to use the TB or a polished upper manifold to use a lower polished manifold... or headers to use an exhaust...

Bottom line is the more of those things you do, the better each mod will work.

I don't get it... why would they be money grubbers if they're just porting different parts?

I know I don't like working for free.

you dont have to buy the tb to get our manifold. our manifold is just ported to work with the tb.
it will work with a stock tb as well but its kinda like this.
whats the point of having bigger lungs when your breathing through a straw.
Manifold doesnt do much without the tb. tb doenst work right without the manifold.
but if we wanted to make you buy them both we would just sell them as a packege only.

Personally, I think getting port & polished U & L Intake Manifold is a waste of money. Unless, you port & polish the block with it. Yeah you are getting bigger holes on your IM's but if the block holes aren't as wide as IM's, the bottleneck is still there.
However, I DO think getting the bored-out TB IS worth the money, regardless of bored-out IM's and the block. Personally, I think the stock TB is too small and bigger TB will definitely help.
If you got the money, upgrade:
TB >> U & L IM's >> Port and Polish the block >> Headers >> Exhaust
Optional:
Cut out the resonator and the catalytic converter.
Along with an Air Intake System, you will easily go (on V6) from 170HP/210Torque to 210HP/260Torque, if not more.
Put Mobil One Fully Synthetic Oil too. It IS the BEST oil. If anyone disagrees with me about Mobil One, you don't know what you are talking about, PERIOD.

Actually getting a larger tb without getting the uim done is just completely stupid and pointless. The tb needs to be port matched to the uim to get a decent benefit. As for the lim you should probably get your heads done.

Im not sure what you are talking about with the whole block bit. If you go p & p and can afford it, get the larger tb to go along with uim, lim and a nice set of heads.

As far as hitting 200 crank hp that can pretty much be done with E/I/H. A few minor adjustments and 210 would be pretty easy to reach.

Now 200 whp is another story. Probably wont see that NA until the cam is finished.

I have changed out LIM gasket myself and when I looked at LIM intake holes and the intake holes on the block, they were the same size. Now, if you got P/P U & L IM's with bigger intake holes while you leave the intake holes on the block the original size, the bottleneck is still there. It's like lining up three people across, trying to get them through a door that can only fit one person at a time.
However, I DO think that the stock TB is too small and it will benefit from a bigger TB. Our IM's are pretty good and efficient as it is, stock.
Well, let me know what you think about that.

Are you talking about boring the engine block to increase the cylinder volume?

I always thought the cylinder heads controlled the flow of air into the cylinder.

I'm at 186 whp all motor right now. getting 14 more without a cam could be possible. heads, matching lower, 3500 upper and a good computer tune may put me there. but when I do my heads I'm getting my short block done too and it will get a cam so I'll never really know
