We see these size plenums on other NA engines often, so I don't think it would be a problem here. We can add N2O ports to any manifold order! You're welcome

 

Sorry if this has been posted, dont have time right now to read all 10 pages of the thread. Is this done yet or available for purchase or is there data sheets of gains etc.?

 

+1 I'd buy it! Any one know if anyone is currently making one? Also is this intake manifold only for boosted 2.4's?

 

i was jus about to ask that Q

 

read the thread but hahn has stated it'd be fine for a modifiend na. Think cams and valvetrain upgrade

 

yea but i thought it was only for boosted 2.4s

 

o so just getting the intake manifold wont really do much if i don't have those other mods then

 

ooic ok will it add anything??? at all

 

Don't know prolly not good for a bolt-on 2.4. If your truly interested call hahn and talk to them. It'd be nice for a direct port set-up

 

hmmm ill prolly email them

 

It is mainly for boosted cars.

 

oic...

 

Sounds great as long as it is fairly easy to install.

 

yea i just emailed them about it

 

I was just wondering would a smaller pully (The GM pully) help us 2.4 guys like the supercharger guys.

 

You mean an underdrive pully right, if so yes it will reduce the rotional mass being spun be the engine thus allowing for quicker lunches and faster acceleration. But it really will not add much if any HP.

 

not to mention if you're running a serious sound system or plan on going sc'ed on the 2.4 the underdrive is a bad idea as it'll give you less alternator current..

a lightweight one is just about as beneficial

 

Any new info on this ?

 

if there is one being made that is a direct fit with no mods to anything in an N/A app, i mite be down.
as long as it will benifit somehow and has a good hp/$ ratio! i would be looking for something that has more low/mid rmp power tho with it trailing off at the higher rpms. because, at least to my knowlege/way im thinking, my intake, headers, and exhaust are already giving me more higher rpm power, with it trailing off in the mid/lower rpms. so i wanna balance that out some. and gain back some of that lower end grunt and accleration. if im thinking wrong, please someone help me out. i wanna make some lower end N/A power. what can i do?

 

It depends on what mods you have a shorty header gives high end gain, a longer tube header gives low end gain, and the same goes for an intake mani, so this one would give high end gain . The way I always thought you want all your mods to get the same type of gains but I'm probably wrong on that
