modify the runner length is a way to change the power curve... longer runner usually means power/torque gains translated lower on rpm than before
now I don't know about those guys you mentioned but you don't specify where (at wich revs) they were searching for more power
even the runner diameter/shape can have a huge role when searching for more power as the intake ports on the head... all need to be engineered as a whole system. A runner is not only a runner... it's diameter or it's optimal lenght depends from intake port size and from plenum shape and size. If then you change the plenum of if you heavily enlarge ports in the head maybe you'll need to change the runners... I had a lot of fun "playing" with pricey engine simulators of a friend's shop and there are a lot of variables in game.
thats general rule... :confused:

3.2 engine revs little bit higher so to tune intake for it, runners must be shorter. Also, 3.2 engine has double vanos (I think) which should give more power in low and middle range so intake system can be more optimized to give more power on high revs.
good point but some 3.0 guys retrofit 3.2 runners for more power :confused:
and m3 GT's they have single vanos and short runners with same intake and more hp

I have some questions about ITB's to disscus with you guys here ....
shorter runners are good for high rpms and longer for low -mid rpms we all ready know why ....
so...
1. Why m3 e36 3.0 with 286hp use long runners and m3 3.0 GT's with 290hp and m3 3.2 with 321hp use sort runners? some 3.0litre people upgrade the runners with EVO ones.
2. e30 m3's have 8.5 litre intake plenum for 2.0-2.5 litre engines. We need big intake plenums?
3. Why metric mechanic in camber pulse intake make tha tube so sort ?it wasnt better if the make them longer ? or make more distance from the intake valve ?
4. dbillas desing use short runners and small plenum and far away the butterfly from the valve . what about this?
5. every m3 have the Maf in the center of the plenum (dbillas too) CSL;s and every other plenum i have see it have the maf boot in the front. which is better?
6. some engines uses metal runners and some others use plastic ones . which is better?
one more
7. how long it has to be the runner in to the plenum ? does it matter ? dbillas does not put the runner in the plenum why?
only this for the momment .
(sorry for my "inglish" )
:cool:

I have one more point that im thinking today if i didnt use a plenum with my ITB's only with straght line runners with some stand alone ECU runner longer does it matter ?

i post some pictures of my ITB setup is not completed yet and am running with stock ECU and some PVC (plastic) tube (temporary of course) for plenum

in metalic disa open the side cover remove the buterfly leave tha axle and you are ready (or leave it like that)
in plastic one brake the plastic butterfly and cut the axle that moves the butterfly a lot of people do that here in greece dont desconnect it otherwise you gone run in save mode map
sorry for my english...

a question for ITBs guys where did you put crankcase ventilation ? and where to connect the canster hose ? and if you have problems with the brake vacum ?
