Horsepower? You mean airflow...? How much airflow will the stock 2G intake manifold manage?

Stock intake-stock throttle body
#4-327, #3-308, #2-300, #1-300
Runner length on #4 runner is 10"
Total CFM 1235

After further review I think the stock manifold they are using is stock evo 8/9 manifold. All the pics look like 8/9 aftermarket manifolds.

Here is a pretty good discussion that pretains to us.

I'm making 452 to the wheels with my stock 2g intake and I don't think it is my limiting factor.

 

[krishansheanh]

Yeah the stock manifold is fairly good. Most people around here get custom ones welded because they're cheap and efficient

 

[Chaosweaver]

a stock 2g intake manifold can take between 420-470ish HP...personally i would trade up at about 400...but thats personal preference.

What? And what happens at 470HP? The danger to manifold light comes on and the floor falls out?

Funny, most DSMers who have actually made these sort of numbers say the manifold didn't become a restriction for them until around 600 HP.

I no rite? What people won't do to boost their post numbers. Misinformation seems to be an everyday thing now, only if there was a team of people who would search for these types of posts and delete them. These people could even issue some sort of warning for repeat offenders, oh well.

That's funny.

Look at 2gGSX. He put down 658 on a stock 2g IM before switching to auto and adding a JMF Drag to his list.

All you have to do is report the post, and they'll get to it when they can.... but not if they never see it.

I wasnt trying to boost anything. Actually, i was trying to help with the information i knew and more that i had found. If that information was incorrect, then i do apologize to the OP. However, that is no reason for you and others to be disrespectful, especially since you're a supporting member and know that one of the rules is "be respectful". Thank you.


OP: If my "misinformation" and personal preference led you down the wrong path, i apologize. I was simply trying to help you by using my, a mechanic friend's, and the search option's information.

 

[eclipse96dsm]

well yea i guess how much boost not horse power sorry about that. and Z to the jokes but time to be serious here so please answer. for what im understanding i could take it any where from 20-35 psi??

 

[SOADweskey]

The stock intake is very strong, I don't know if anyone has ever damaged one from to much boost. I have only gone up to 34psi on mine and I never even worried about it. I don't think the cast aluminum is going to burst from boost before you engine melts itself.

 

[lb_gst99]

So this thread got jacked... but i'll agree with SOAD even though I'm not boosting 32psi..I've seen to many DSM's with 600+ that have stock 1g or 2g IM. You'll be fine. No need to spend the extra money, depending on your HP goals.

 

[eclipse96dsm]

well my hp goals are definitely 500 for now but my bottom end is made for 800+ any how. whats the best intake manifold gasket i could use?

I use this and love it. Perfect fit and a noticeable decrease in IM temps.
