At least I have full 2.5" exhaust from the manifold back to get the extra air out and a tune. I hear 65 is nice on a none boosted 3400 but to each there own.

Agreed.

See, this is the whole problem with most of you newbie modders on this site. You don't even understand how the engine functions and how mods affect it.

You are not getting any "extra air" out with a larger exhaust. You aren't getting any "extra air" in either with a larger TB or a CAI either. When you change those things you gain HP from removing restrictions that cause pumping losses in the engine (essentially friction). You aren't increasing air volume.

First thing you need to do is research volumetric efficiency, then get back to me.

Wow, and all this time I thought I was getting a higher CFM

Wow ****y. NOOB? Iv owned 2 Grand Ams the past 7 years and have been a active member on GAOC for years. I know my Grand Ams pretty well and I'm continuing to learn. Anyways you're telling me that removing restrictions and making a bigger breathing space isn't going to let it more air? By having a restriction of air is going to cause less air to come in at one time then if there were no restrictions. By removing restrictions you allow more air to pass through easier and faster Like if I had something stuck in my throat id obviously be getting less air do the restriction and by removing the restricting I would be letting more air into my throat again and I would breath easier of coarse.

If I'm wrong then sorry

Just because you own something does not mean you know everything about it. Sean you are a cool guy but hell even some things Aaron says I have to go Google to brush up on, He knows what he is talking about (most of the time

) with engines.

If you have stock exhaust manifolds then having a bigger exhaust will not make it "flow more air".

I've owned two Grand Am's over the past four years....and? Crap my neighbor has had two since like 1997, he is an expert.

Bryle James · 08-19-2013, 09:56 PM

Basically to increase throttle body size for more air, there will need to be a lot of other supporting mods to fully maximize the potential of it. Think of trying to funnel a large amount of air through a small tube, cut and joined in three sections. Expand the first section, but it's still going to bottle neck at the smaller, middle section. Expand all three sections, then you'll have a much more efficient air flow.

this is hilarious xD

Never said i knew everything about a Grand Am or tried to act like i knew everything about a Grand Am. I said I know my Grand Am's pretty well. I hate when people put words in my mouth.

Milzy headers are next even tho he pissed me off recently I like his headers from the reviews iv seen

Thank you for explaining.

99ga · 08-19-2013, 10:18 PM

so how about Having a CAI>65mmTB>PORTED INTAKES>HEADERS>2.5"downpipe>custom exhaust? would THAT get you the "extra air" he is talkkng about?

Bryle James · 08-19-2013, 10:37 PM

Depending on how well the ported intake manifold and head can flow, the 2.5 exhaust may be the bottle neck.

sleepyalero · 08-19-2013, 10:48 PM

Well 2.5 inch is ideal n/a on these cars really. 3 inch for boosted applications is best ideal option.

How did he make you mad?

Bryle James · 08-19-2013, 11:01 PM

I can think of a couple applications where a 3 inch is perfect for a naturally aspirated 2.0 or a 2.4 liter engine. That's why I say it depends how well the engine can flow. So yes, you may be right in saying 2.5 is all that is needed for this car.

sleepyalero · 08-19-2013, 11:25 PM

Well im talking 3400. The 4 cyl's are new game for me so it could be different there. Idk anyone boosted or n/a running anything bigger then 3"
