For a Race only intake manifold, witch one would you buy for a all motor B-18 set up. And Why.......

Alot of people with very deep pockets go with the AIR mainfold. it has been clamied that it out flows a certin size set of ITB's ( i cant remeber the throttle body diameter of the ITB's it is clamied to out flow though)
it is a pretty penny though. i belive from AIR it is 1800.00, and from endyn it is 1200.00

for a more economical manifold you could try the victor X for race only apps. they are said to lose power in the mid range but to gain a couple poines up top. but its manily for FI.

then theres Skunk2/ITR manifold. you can search and find all sorts of stuff on that one.

then theres the AEBS typhoon manifold. still waiting for dynos on that one (are there any yet?)

Then if you are running a hard core high compression race car 13:1 CR's i would begin to look in to a set of TODA, or TWM ITB's

those are the popular ones right now.
hope that helped some...you could also search and find some more stuff too though.

ITB's can be very rewarding, but honestly you can get great gains just from using your standard oem R manny.

plus they are a pain in the *** to tune.

 

There are atleast 2-3 dyno's so far on AEBS. They seem to be working well and making good power over ITR manifold.
