Stock 2g mani. How much hp possible?

[boost97gst]

Can i make 400whp with my ported 2g mani? I've got all supporting mods(In my profile) and engine is coming back soon. I would hate to find it wont flow enough after reassembling everything though. Ive also ported the o2 housing just about as much as humanly possible . Its pretty damn big.
Same for the stock 2g IM. 400 possible on that?

Edit: Im sincerely not trying to "bench race" . Im simply asking if i need to upgrade a couple components while theyre easily accesible

Yes. There are numerous members who have made significantly more power than that on the 2G manifold.

Ok, thank you. You can mark this resolved if youd like.

If you're interested you can look through the members' dyno results. Click on the member's user name to see their setup. You should see 2G IM's starting to show up in the low 400's power range.
