Tumble flaps are the little flaps in the manifold that vary their "openness" at lower RPMs in order (correct me if I'm wrong) to run slightly lean. It is an emissions sort of thing.. They open up as you go to higher RPMs ( I think somewhere in the 3000rpm range).focus_racer19 said:what the hell are tumble flaps? And will the MM intake manifold fit a 2.3?
I think the word on the street is that if it retains the tumble flap capability, you will have to swap them onto the new manifold. Aero could prolly speak to this better.focus_racer19 said:so all I gotta do is take the MM outta the box and bolt it on?
MM intake vs. Cossi means:Canadian ST said:I would have to go with the Cosworth. Cosworth have proven them self in the racing industry. I also think the Cosworth manifold is the better looking of the two....
a) Walter posted a dyno a while back on focaljet of him working on the silver car which was very similar to the black car, the differences being a .9 more compression and the new intake manifold. he made significantly more torque and hp and he's not through with the manifold or the tuning.y2kpedo said:a)has more torque been proven?
b)has emission legal been aproved?
c)looks might be irelevant but real racer apriciate brand names, such as AEM vs BOMZ (for the zetec engine)
im not sure how this is going to be emission legal, specially on the green states. $$ has to in to that get a CRAB legal "thing."
please update me if this has already been done.
and about the price, i would not mind if it was the same price as the cossi as long as it is better. with more torque, the tumble flab, CARB legal, etc
